INSPECTION
After removing the VC-MP temperature controller from
the shipping container immediately inspect the unit for
damage resulting from mishandling in shipping. Inspect
for loose components and mechanical damage such as
bent sheet metal, marred front panel screen, etc.
Remove the spare ABC15 fuses and mainframe zone
edge connector contact (required for anti-arc circuit)
and save them for later use.
Note: If the unit appears damaged or the container
is missing components, contact your sales
representative immediately! Use or modification of
the controller or its packaging will decrease the
likelihood of freight claim reimbursement.
INSTALLATION
THIS VC-MP IS EQUIPPED WITH A
HIGH VOLTAGE ANTI-ARC CIRCUIT!
AND IS ENABLED – TO PREVENT
ELECTRICAL DAMAGE TO THE
CONTROLLER IF ACCIDENTALLY
REMOVED FROM THE MAINFRAME WITH
POWER APPLIED.
The controller WILL NOT apply power to
the load unless mainframe zone edge
connector contact #3 is installed.
Inspect each mainframe zone edge connector for the
required contact. If the contact is not already installed
remove the mainframe rear cover (refer to
manufacturer instructions) and install the contact
supplied with the VC-MP. (Insure contact is locked in
the connector by gently pushing on it from the front.)
Step 1: Verify installation Step 2: If not, install
of contact. provided contact
Note that the contact itself completes the triac gate
(drive) circuit. No wiring, or wire connection, is required
to the #3 edge connector contact.
The anti-arc circuit can be disabled by installing a
#22-28 AWG wire jumper into the printed circuit board
jumper position P5. (Soldering is required. See Fig. 2,
Component Layout.)
It is highly recommended that the anti-arc circuit
not be disabled in this manner! If the controller is
inadvertently installed or removed from the mainframe
under power it will suffer severe damage, and possibly
be destroyed. The user is encouraged to take
advantage of this protective feature.

WARNING!
THE CONTROL SYSTEM MAINFRAME MAIN
POWER DISCONNECT MUST BE IN THE “OFF”
POSITION BEFORE INSERTING OR REMOVING
CONTROL MODULES TO PREVENT OPERATOR
INJURY AND DAMAGE TO CONTROL SYSTEM
COMPONENTS!
Check the controller red power switch (Fig. 1 Item #1)
insuring that it is in the “Off” (O) position. Pull the
plunger of the black locking device (Fig. 1 Item #8)
back into the “out” position.
Align the controller PC board top and bottom rear
corners with the respective card guide rails in a
mainframe control zone. Slide the controller into the
frame, keeping it parallel with the frame surfaces, until
it meets resistance of the edge card connector. Place
thumbs on the upper and lower right corners of the
controller faceplate and firmly press it into the
mainframe until the backside of the faceplate meets
the frame.
Gently push the plunger of the black locking device into
its locked position.
OPERATION
Refer to Figure 1 to become oriented with the
controller displays, indicators and user controls.
The following control events are listed in
order of priority.
POWER ON
FIRST TIME USE
When the controller is turned on for the first time it will
start with the following factory preset parameters:
United States: ……...…….…. Automatic Control Mode
Setpoint = 200°F
Degree Mode = Fahrenheit
Export Models: ……….…….. Automatic Control Mode
Setpoint = 100°C
Degree Mode = Celsius
REPEAT USE
When power is reapplied the controller will operate
using the same modes that it was using at the previous
power off (unless any of the advanced feature DIP
switch settings have been changed).
For example, if the controller was in Auto Control mode
when it was turned off it will return in Auto mode.
Likewise if the controller was shut off in Manual Control
mode it will return in Manual mode.
WET HEATER GROUND FAULT
This diagnostic routine is bypassed if the process
temperature is greater than 212°F (> 100°C).
When the controller is first turned on output power
is disabled for 15 seconds. During this time period
the controller monitors load current (amps). If the
controller, with its output power off, monitors no current
flow, or current (amps) less than 200 milliamperes
(0.20 amps), it determines that there is no recognizable
ground fault and continues in Slow Start Control mode
as detailed below.
THIS DIAGNOSTIC ROUTINE IS PERFORMED AT
START-UP IF THE CONTROLLER IS IN AUTO
CONTROL MODE OR MANUAL CONTROL MODE!
If in Manual Control mode the controller will display
0% power output (disabled) until the 15-second time
has elapsed. Upon completion of the test, without a
ground fault, the controller will continue in Manual
Control mode using the percentage of power output of
the push button input switch.
The user may increase output power during this
test. However, doing so will abort the wet heater
ground fault diagnostic routine and also prevent the
controller from restoring the previously saved power
setting!
NO THERMOCOUPLE AT START-UP
If in Auto Control mode, and a thermocouple fault is
determined due to a lack of an acceptable T/C signal
the controller will continue to disable the output and
display the appropriate T/C diagnostic code. See
Diagnostic modes listed below.
If the controller is set to Manual Control mode and
no T/C signal is applied the wet heater ground fault
diagnostic will still be active.
Note: The alarm output will not be active in this
condition unless the controller is switched into Auto
Control mode. Upon start-up in Manual Control mode
with no T/C signal present, the VC-MP controller
assumes that the operator has intentionally not
provided T/C input, therefore disabling the alarm
output.

User’s Manual October 18, 2016

FAULT DETERMINED
If the controller senses current flow greater than or
equal to 200 milliamperes (0.20 amps), it deduces that
current is leaking to ground by a conductive path
caused by moisture. In this event the following
diagnostic code is displayed in the Process
Temperature display window accompanied by the
associated condition code LED:
DISPLAY SHOWN WITH FAULT INDICATOR
In this event the VC-MP controller will also apply a
signal on the mainframe communications bus
(optional) that can be used to activate an audible
and/or visual alarm accessory.
In the event of this fault the operator may continue in
one of the following three ways, listed in order of
precautionary weight:
1. The operator can turn the control system off
and investigate the severity of the probable
fault.
2. The operator can wait for controller response.
The VC-MP will continue to monitor the current
(amps). If the current (amps) is reduced to less
than 200 milliamperes (0.20 amps), or the
Process Temperature exceeds 225°F (107°C),
the controller will continue with normal
operation.
If in Auto Control mode and current flow
(amps) is decreased, and the temperature is
lower than 225°F (107°C), it enters the Slow
Start Control mode.
If in Manual Control mode the controller will
stay at 0% output power (inhibited) until the
current is reduced or the temperature exceeds
225°F (107°C). In either case the fault will be
cleared and the previous power setting will be
restored, and the module will operate normally.
If in Manual Control mode and no
thermocouple signal is present the wet
heater fault will continue until current flow
(amps) stops, regardless of the load
temperature. (Without T/C feedback the VC-
MP has no way to determine load
temperature.)
3. The operator can override the diagnostic
routine. The controller must be set in Manual
Control mode and power must be manually
increased from 0%. (See Function Control
instructions below to change control modes).
CONTROL METHODS
SLOW START CONTROL
For Wet Heater Bake-Out
Disabled If In Manual Control Mode
SLOW START MODE INDICATOR
Upon start-up, the controller always enters Slow Start
Control mode when all of the following conditions have
been met:
1. The controller is set for Auto Control operation.
2. The process temperature is less than 212°F (<
100°C).
3. The wet heater diagnostic is completed without
a fault condition.
Slow Start control utilizes a special power control
routine designed to avoid heater destruction due to
conductive paths to ground caused by moisture. While
maintaining a low power setting, the VC-MP controller
ramps the load temperature to 212°F (100°C) at a 1-
degree per second rate of rise. When 212°F (100°C)
has been achieved the controller quickly reduces
power to slow the temperature rise for a period of 1
minute. Upon completion the controller will continue to
drive the process temperature to the setpoint.
To disable Slow Start Control the controller can be
momentarily changed to Manual Control mode and
then back to Automatic Control mode.

AUTOMATIC CONTROL MODE
In Automatic (Auto) Control mode the VC-MP controller
uses a PID algorithm to determine the required output
power to hold the Process Temperature equal to the
Setpoint Temperature.
This type of control is a “closed loop” system and
requires a thermocouple feedback signal. The Closed
Loop mode indicator indicates this control mode:
CLOSED LOOP MODE INDICATOR
The Setpoint Temperature is determined by the
operator and indicated on the push button switch:
0
25
SETPOINT DISPLAY
The Setpoint can be easily adjusted up or down at any
time during Auto Control mode operation by
depressing the increment or decrement push buttons
for each individual digit.
AUTOMATIC PID TUNING
The VC-MP controller uses a PID (three term) control
algorithm to determine the required load power needed
to reach and maintain the Setpoint Temperature. Every
thermal system has different characteristics. To
accurately control each dynamic system the VC-MP
must “learn” each load’s characteristics individually. In
addition, every system’s variables change with
temperature changes. For example, a load’s set of
control variables may be different at 200° than at 350°.
To accomplish “learning” each load’s variables and to
eliminate complex operator intervention the VC-MP
controller automatically enters a “tuning” routine when
the Process Temperature reaches a point less than or
equal to 80°F (45°C) below Setpoint Temperature. The
controller will go through a sequence of applying
different levels of power to monitor load response. The
VC-MP takes the information it “learned” and adjusts
the PID control variables accordingly.
Note: The VC-MP automatically calls this tuning
routine at power-on regardless of the current Process
Temperature. The controller also repeats this tuning
process when the operator makes a Setpoint
Temperature change greater than or equal to 100°F
(55°C). The controller will not tune if it is turned on
with a process temperature greater than the
setpoint.
MANUAL CONTROL MODE
In Manual Control mode the VC-MP controller
regulates load power determined by the user selected
Power Output setting. The power delivered is constant
and will only change with user input.
This type of control is an “open loop” system and
requires no thermocouple feedback signal. The Open
Loop mode indicator indicates this control mode:
OPEN LOOP MODE INDICATOR
The Power Output setting is determined by the
operator indicated on the push button switch:
0
25
POWER OUT DISPLAY
The Power Output setting can be easily adjusted up or
down at any time during Manual Control mode
operation by depressing the increment or decrement
push buttons for each individual digit.
The Power Output setting is two whole digits and a
tenths, for example, 25.5% power (note the decimal
representation on the front panel graphic). The power
output is rounded per the tenths digit to the nearest
whole number.
USER INTERFACE
The user makes various control mode and setting
changes using the two momentary switch keypad and
the Setpoint / Power Output setting push button switch
on the controller front panel (Fig. 1 Item #3, 4 & 5).
The operator simply pushes and holds the desired key
until the variable change is recognized on the
appropriate display.
It may be noticed that the VC-MP controller does not
accept quick individual key entries. The operating
program has a switch closure delay time requirement
that must be met before the controller will accept input
as a good key and react accordingly. This
precautionary measure is included to prevent the
controller from reacting to environmental noise.
CAUTION: The operator should not use anything other
than their finger to actuate a keypad key! The use of
pens, pencils, screwdrivers or other tools will damage
the keyboard assembly. Such damage is considered
abuse and is not included under warranty coverage.

PCS Company VC-MP 15 Amp Hot Runner Controller Document No.: ED-1503-MN-006-A

The individual controls are described as follows:
0
25
SETPOINT / MANUAL POWER OUTPUT
PUSH BUTTON SWITCH
The Setpoint / Manual Power Output push button
switch is the operator’s means of adjusting the desired
setpoint temperature (Closed Loop / Auto Control
Mode) or Percent of Power Output (Open Loop /
Manual Control Mode).
The input value can be easily adjusted up or down at
any time by depressing the increment or decrement
push buttons for each individual digit.
The Power Output setting is two whole digits and a
tenths, for example, 25.5% power (note the decimal
representation on the front panel graphic). The power
output is rounded per the tenths digit to the nearest
whole number.
If the VC-MP is operating in one of the View Modes
(instantaneous power output monitoring or load current
/ amps mode) and the value of the push button is
changed the controller will terminate View Mode and
the LED display is returned to its default display
depending on the operating mode in use.
AUTO / MANUAL CONTROL KEY
The Auto / Manual Control Mode key switches the VC-
MP between Automatic (Closed Loop) control mode
and Manual (Open Loop) control mode.
If the Auto / Manual key is pressed when in a View
screen (see below) the controller will terminate View
and return the controller to the default operating
display. (Setpoint display in Auto Control and Power
Output % in Manual Control.)
VIEW PROCESS MODE KEY
The View Process key is active in both Auto and
Manual Control modes. The first closure of the View
key will activate:
CURRENT (AMPS) MONITOR MODE:
Whether operating in Auto Control mode or Manual
Control mode the VC-MP allows the operator to
continuously monitor load current (amps). The
monitored value is the average current (amps) being
delivered to the load. Because the VC-MP applies
power to the load using a pattern of voltage pulses,
true instantaneous current would be rapidly changing
from second to second and would be difficult for the
operator to interpret. The displayed average value is a
much more useful quantity to the user.
CURRENT (AMPS) DISPLAY
When in View AMPS mode the of the LED
display.
When operating in Auto Control mode a second
closure of the View key will activate:
AUTOMATIC CONTROL (%) OUTPUT POWER
MONITOR MODE:
As stated above, when in Auto Control mode the VC-
MP controller uses a PID algorithm to determine the
required output power to hold the Process
Temperature equal to the Setpoint Temperature. As a
result the output power is constantly changing. The
operator can view the instantaneous power settings
being applied to the load by using the View key.

LOAD POWER INDICATION
In either Auto Control mode or Manual Control mode
power being delivered to the load is indicated:
LOAD POWER INDICATOR
The indicator flashes concurrently with the firing
(closing) of the load power output device (triac). Power
is delivered by time proportioned preset patterns. The
time interval between pulses is proportional to the
power requirement. The lower the power, the slower
the flash. Conversely, the higher the power the faster
the flash. For example, at maximum power output
(99.9%) the LED indicator will be on continuously. With
power off (< 0.5%) the indicator will never turn on.
WARNING! The Load Power Indicator lights
when the triac is turned on by the controller’s MCU
and is independent of voltage applied to the load!
The indicator not being illuminated is not a guarantee
that the control device (triac) is open. The VC-MP
controller will recognize a shorted triac fault (See
Diagnostic instructions below) and will notify the
operator. But, in this situation, the VC-MP controller
can not open or control the failed triac.
For this reason it is imperative that under a load fault
condition that the operator switch the controller power
disconnect switch (Fig. 1 Item #1) and also the
mainframe system disconnect to the “OFF” positions
before removing a controller or interconnect cabling.
TEMPERATURE SCALE INDICATION
- or -
SCALE INDICATOR
The VC-MP controller will operate in either the
Fahrenheit or Centigrade temperature scales. DIP
switch SW4:1 must be set accordingly before the VC-
MP controller is turned on. See USER SELECTABLE
OPTIONS above or refer to Fig. 2, Component Layout.
It is not necessary to calibrate the VC-MP when
changing between temperature scales.
DIAGNOSTICS
The VC-MP controller has the capability to diagnose a
variety of unusual operating and fault conditions and
alert the operator so appropriate adjustments can be
made.
These conditions are described below and presented
with the associated display mnemonic and Condition
Indicator.
OVER SETPOINT ALARM INDICATION
Alarm mnemonic alternates with Process Temperature
display.
When the Process Temperature exceeds the setpoint
by 30°F (17°C) or more the VC-MP alerts the user of
an over-temperature alarm condition.
In this event the VC-MP controller will also apply a
signal on the mainframe communications bus
(optional) that is used to activate an audible and/or
visual alarm accessory.
UNDER SETPOINT ALARM INDICATION
Alarm mnemonic alternates with Process Temperature
display.
When the Process Temperature is lower than the
setpoint by 30°F (17°C) or more the VC-MP alerts the
user of an under-temperature alarm condition.
In this event the VC-MP controller will also apply a
signal on the mainframe communications bus
(optional) that is used to activate an audible and/or
visual alarm accessory.
Note: This feature is only active during normal Auto
Control mode operation. It is disabled through Slow
Start Control and PID Auto Tuning modes and
initializes when the process temperature reaches
setpoint.

Accidental Fault Indication may be invoked when
trying to start very heavy, slow changing loads. If this is
suspected the operator can override the fault by
increasing the Output Power setting. This action should
be continued until the Process Temperature is driven
to or above Setpoint Temperature. Once this
temperature has been reached the VC-MP can be
switched back into Auto Control mode and normal
operation should commence.
If this attempt fails to increase the Process
Temperature a true fault condition may exist. The
operator may take the following course of action:
1. TURN OFF CONTROLLER AND MAINFRAME
SYSTEM POWER and disconnect the
interconnect cabling from the mold. It is now
safe to thoroughly inspect the suspected faulty
thermocouple and take appropriate action.
Service personnel should make certain that the
appropriate T/C is connected to its respective
controller and inspect all associated wiring.
2. If the operator allowed the controller to run at
99% power and realized no temperature
increase, and trouble shooting the control
system power and T/C circuits determined no
error, there could be a design problem with the
mold. If the tool is being run for the first time
and will not come up to temperature, the watt
density of the problematic zone heater may be
too low. A thorough review of the mold design
by a qualified engineer may be necessary.
Additionally, low line voltage can lead to poor
response from the heaters. Again, if no
thermocouple errors are discovered, a full
system analysis may need to be done by
qualified personnel.
IF THE CONTROLLER IS IN MANUAL CONTROL
MODE it will continue to supply output power even
though a T/C fault is indicated. (The feedback is not
necessary for “open loop” control).
USER SELECTABLE SHORTED T/C
SAMPLE TIME or DISABLE
As stated above, accidental fault indication may be
invoked when trying to start very heavy, slow changing
loads. If this is suspected the operator can change the
Shorted T/C diagnostic test sample time. The VC-MP
requires a temperature rise of 3°F (1.7°C) over a
preset time period to not call a Sho fault. The factory
default time is 90 seconds, but heavy thermal loads
often require more time than this to register changes in
temperature. If the user suspects such a load is being
controlled the test time period may be changed to 250
seconds by activating the “Sho T/C LONG DELAY” DIP
switch of SW4. (See Fig. 2). The switch bank SW4
must be set to the user’s requirements as detailed in
Figure 2, Component Layout.
If the user continues to experience errant fault
recognition the Shorted T/C diagnostic can be
disabled. In the same manner as enabling the Sho T/C
long delay, the “Sho T/C *OFF*” DIP switch of SW4
must be activated as detailed in Figure 2, Component
Layout.
CAUTION: IT IS STRONGLY RECOMMENDED
THAT THE SHORTED T/C DIAGNOSTIC NOT BE
DISABLED! Under this condition the VC-MP will
continue to apply full (99%) output power to a load that
may have a faulty thermocouple. Under these
circumstances THE PROCESS TEMPERATURE
DISPLAY IS NOT REPRESENTATIVE OF THE TRUE
TEMPERATURE OF THE LOAD. The heater may be
creating an extremely high temperature that could
create dangerous and volatile conditions.
To change the printed circuit board SW4 Sho DIP
switches it will be necessary to turn the VC-MP
controller and mainframe power **OFF** and remove
the controller from the mainframe.
WARNING!
THE CONTROL SYSTEM MAINFRAME MAIN
POWER DISCONNECT MUST BE IN THE “OFF”
POSITION BEFORE INSERTING OR REMOVING
CONTROL MODULES TO PREVENT OPERATOR
INJURY AND DAMAGE TO CONTROL SYSTEM
COMPONENTS!
Switch SW4 is located near the top of the printed
circuit board and is easily accessible without removing
the VC-MP side panel.
Note that if both the “Sho LONG” and “Sho OFF” DIP
switches are accidentally selected the VC-MP will
recognize the errant switch selection and respond to
the Shorted T/C diagnostic in the Long 250 second
time period. Having both Sho DIP switches activated
will be interpreted as an error by the VC-MP.
Load Fault
OPEN OUTPUT (LOAD OR TRIAC)
DISPLAY SHOWN with
LOAD FAULT INDICATOR
When the VC-MP senses load current (amps) less than
or equal to 100 milliamperes (0.10 amps) while it has
output power set greater than 25% this fault mnemonic
will be displayed on the Process Temperature display.

PCS Company VC-MP 15 Amp Hot Runner Controller Document No.: ED-1503-MN-006-A
User’s Manual October 18, 2016
Page 12 of 15
There is either a failed open condition with the output
control device (triac) or an open in the load power
circuit, such as the interconnect cabling, mold
connector or heater wiring.
THE VC-MP ANTI-ARC CIRCUIT MUST BE
COMPLETED! (Refer to the voltage anti-arc feature
section above). If the Anti-Arc circuit is not closed by
either the mainframe edge connector contact #3
(preferred, anti-arc enabled) or by installation of PC
board jumper P5 (anti-arc disabled), the VC-MP MCU
will not be able to turn the power output control device
(triac) on!!
The VC-MP controller in the faulty zone may be
swapped with another working controller to verify
proper operation of the output control device (triac). If
the triac fails open the controller MCU will not be able
to apply power to the load.
This Load Diagnostic is active in either Auto or
Manual Control modes.
The controller will remain in Auto Control mode with
output power on until the load current (amps) exceeds
100 milliamperes (0.10 amps). If this occurs the VC-
MP will then continue in normal Auto Control mode.
In this event the VC-MP controller will also apply a
signal on the mainframe communications bus
(optional) that is used to activate an audible and/or
visual alarm accessory.
Disable oPO: Driving very low current loads or a high
impedance input of a load switching device such as a
solid state relay (SSR) could result in a false open
output fault. It may be necessary to disable the oPO
Open Output diagnostic by activating the “oPO *OFF*”
DIP switch of SW4 as detailed in Figure 2 of the
Component Layout.
To change the printed circuit board SW4 oPO DIP
switch it will be necessary to turn the VC-MP controller
and mainframe power **OFF** and remove the
controller from the mainframe.
Switch SW4 is located near the top of the printed
circuit board and is easily accessible without removing
the VC-MP side panel.
Load Fault
SHORTED OUTPUT (LOAD OR TRIAC)
DISPLAY SHOWN with
LOAD FAULT INDICATOR
When the VC-MP senses load current (amps) greater
than 100 milliamperes (0.10 amps) while it has output
power turned off (0% output power) it will display this
fault mnemonic on the Process Temperature display.
The controller will remain in Auto Control mode with
output power off (0%) until the load current (amps)
returns to less than or equal to 100 milliamperes (0.10
amps) If this occurs the VC-MP will then continue in
normal Auto Control mode.
WARNING!! The VC-MP is not in control of the load
and corrective measures should be taken
immediately!
There is either a failed closed (shorted) condition with
the output control device (triac) or an uncontrolled
closure of the load power circuit beyond the control
module that is causing the load to heat out of control.
The operator should turn VC-MP controller power and
the mainframe control system power “OFF” and
determine the cause of the problem.
The VC-MP controller in the faulty zone may be
swapped with another working controller to verify
proper operation of the output control device (triac). If
the triac fails closed the controller MCU will not be able
to turn off power to the load.
It is critical that the VC-MP controller power switch
be turned “OFF” before removing the VC-MP
controller! If the triac has failed shorted, there may be
current flow through the module. Removing the
controller under these circumstances can result in
operator injury and controller / control system damage.
THE ENABLED VOLTAGE ANTI-ARC FEATURE
WILL NOT ELLIMINATE THIS DANGER!
This Load Diagnostic is active in either Auto or
Manual Control modes.
The VC-MP has set the output power to 0% (off) and if
in Manual Control mode the Power Output Push
Button Switch will be inactive! The VC-MP will not
allow the operator to increase power in this
uncontrolled situation.
If the probable fault drives the Process
Temperature out of range (exceeds 999°F / 537°C)
the shorted output mnemonic (ShO) will alternate with
the open thermocouple mnemonic (oPE). This manner
of indication was selected to notify the operator that a
short fault might have driven the temperature over
range, rather than defaulting to only the open
thermocouple indication. If these two fault conditions
occur the VC-MP will be forced into Manual Control
mode with output power turned off (0%).

PCS Company VC-MP 15 Amp Hot Runner Controller Document No.: ED-1503-MN-006-A
User’s Manual October 18, 2016

In this event the VC-MP controller will also apply a
signal on the mainframe communications bus
(optional) that is used to activate an audible and/or
visual alarm accessory.
AUTOMATIC T/C FAULT HOLD
CONTROL MODE TRANSFER
ALTERNATING MNEMONICS
The VC-MP controller has the ability to automatically
switch from Auto Control mode to Manual Control
mode and maintain output power in the event of T/C
loss (closed loop break). When this transition is made
the VC-MP will continue with ouput power set to the
average power required to maintain setpoint prior to
the T/C fault.
When the VC-MP enters this mode of operation the
above detailed mnemonics will alternate on the
Process Temperature display at 3-second intervals.
The alternating mnemonics alarm the user of a fault
condition, indicate the type of fault (reversed T/C used
in the example above) and inform the operator that the
VC-MP automatically changed to Manual Control
mode.
Note: This output power level will most likely not be
able to hold the former setpoint but it will bring the load
to a constant temperature that may be close to the
former setpoint value. As the controller is working in
Auto Control mode it is continually changing output
power to maintain Setpoint Temperature. These
continuous changes are required to keep up with
process upsets to the thermal system.
When this occurs the value of the Power Output
Setting of the push button switch will be ignored
as the VC-MP controller will continue to deliver the
average power to the load.
If the user changes the Power Output push button
switch HOLD will be terminated and the power
output will immediately be controlled by the push
button switch, regardless of what the HOLD power
was.
Additionally, when the user changes the power
setting the VC-MP will record the Manual Control
Mode setting in its non-volatile memory and the
controller will return to Manual Control mode the
next time it is turned on.
ENABLING AUTO T/C FAULT HOLD
The VC-MP ships from the factory with the Auto T/C
Fault Hold feature enabled.
To disable the feature: Prior to applying power the
operator must disable this function. The “AUTO T/C
HOLD” DIP switch of SW4 must be changed from the
factory default setting (T/C Fault Hold enabled) to the
open circuit (“deactivated”) position. (See the
Component Layout of Figure 2.)
Once disabled the VC-MP will not automatically
change to Manual Control mode with power in the
event of a T/C fault. To again enable the feature the
operator must switch the DIP switch to the active, or
closed, position.
TYPE “K” THERMOCOUPLE
SELECTION
The VC-MP can be changed to operate with type “K”
Thermocouple feedback. Prior to applying power the
operator must change the T/C input to type “K.” The
“TYPE ‘K’ T/C” DIP switch of SW4 must be changed
from the factory default setting (“J” type) to the closed
circuit position (“K” type). (See the Component Layout
of Figure 2.)
The thermocouple amplifier and conditioning circuitry
of the VC-MP was designed to operate specifically with
the industry standard type “J” thermocouple. By
selecting the type “K” option, the software of the
controller mathematically compensates for the
difference between the type “J” and type “K”
thermocouple signals and is accurate enough for most
control applications. Recalibration of the VC-MP in type
“K” mode is not necessary.
MAINTENANCE
The VC-MP controller requires very little maintenance
for continuous, reliable and accurate operation.
Depending on the atmosphere of the facility it may be
appropriate to periodically clean the main printed circuit
board assembly. This should only require blowing off
dust and debris using clean and dry compressed air.
If the printed circuit board has been soiled and the air
is not sufficient it is acceptable to clean the board,
components and component leads using ISOPROPYL
ALCHOHOL only. Be sure that the board and
components are completely dry before reapplying
power to prevent unsafe and damaging short circuits.
If the faceplate / keyboard assembly needs to be
cleaned use only a DAMP RAG AND MILD
DETERGENT. Gently rub the polycarbonate overlay to
remove any oil and debris. Be sure that all components

PCS Company VC-MP 15 Amp Hot Runner Controller Document No.: ED-1503-MN-006-A
User’s Manual October 18, 2016
Page 14 of 15
are completely dry before reapplying power to prevent
unsafe and damaging short circuits.
CALIBRATION
The manufacturer recommends that the VC-MP
controller be calibrated every 12 months to maintain
accuracy and to perform within the operating
specifications. Arrangements can be made with a sales
representative to have the VC-MP controllers
calibrated using standards and equipment traceable to
each region’s respective governing agencies.
TEMPERATURE CALIBRATION
There are two temperature calibration potentiometers
on the main printed circuit board (See Fig. 2). Pot R27
is used to set the low end of the temperature scale and
pot R19 is used to set the high end of the scale.
For the highest accuracy it is recommended to
calibrate the VC-MP controller in the degrees
Fahrenheit (°F) temperature scale.
A “J” type thermocouple calibrator (millivolt source) is
required to calibrate the VC-MP. The simulated T/C
signal must be applied directly to the controller edge
card “finger” contacts. (Fig. 2; T/C polarity is critical).
TYPE “J” T/C TEMPERATURE CALIBRATION
STEP 1: With the thermocouple input set to 200°F
(93°C). Slowly turn Pot R27 (Low Cal) as required until
the VC-MP Process Temperature display reads the
same as the simulator (200°F / 93°C).
STEP 2: Change the calibrator input to 800°F (427°C).
Slowly turn Pot R19 (High Cal) as required until the
VC-MP Process Temperature display reads the same
as the simulator (800°F / 427°C).
Turn the potentiometers slowly and STOP when
resistance is met to avoid unintentional physical
damage to the components!
STEP 3: Repeat steps 1-2 as many times as
necessary until the low end and high end displays
consistently match the simulator.
Note: It should only be necessary to repeat these steps
2-3 times to calibrate the VC-MP. If calibration has not
been achieved after several attempts there may be
component malfunctions that need serviced. Contact
your local sales representative or distributor to make
arrangements to return the controller for repair by an
authorized technician.
TYPE “K” T/C TEMPERATURE CALIBRATION
It is not necessary to recalibrate the VC-MP using a
type “K” T/C input to operate properly in type “K”
Thermocouple input mode. Insure that the controller is
in calibration using the standard type “J” T/C input.
CURRENT (AMPS) CALIBRATION
There is a current (amps) calibration potentiometer on
the main printed circuit board (See Fig. 2). Pot R46 is
used to set the load current scale.
STEP 1: Drive a known resistive load with the VC-MP
set in Manual Control mode with output power set at
99%. Full output power will eliminate the pulsing action
of the VC-MP lower output power and is the only way
to accurately calibrate the current (amps) circuit.
The resistive load may be a heater less than 3600
watts. Whatever type of load is chosen must be
capable of safely dissipating the supplied power of the
VC-MP to prevent a hazardous condition.
STEP 2: Unless it is already known, measure and
record the resistance (ohms) of the load and the
applied voltage, and calculate the load current. For
example:
240 Volts (applied) ÷ 41 Ohms = 5.8 Amps
OR
If the power (watts) of the load is known, calculate the
load current using the applied voltage. For example:
1400 Watt Heater ÷ 240 Volts (applied) = 5.8 Amps
STEP 3: Switch the VC-MP into Current (Amps)
Monitor mode.
STEP 4: Adjust pot R46 until the Current (amps)
Display of the VC-MP displays the correct calculated
load current (amps). From the examples above, 5.8
amps.
Turn the potentiometer slowly and STOP when
resistance is met to avoid unintentional physical
damage to the components!
