Electrical Noise / Interference
Process Technology electronic controls are engineered, tested and
manufactured to conform to Europe’s CE levels of electrical noise and
interference found in typical industrial installations.
It is always possible for electrical noise and interference to exceed the level
of designed-in protection. This can happen, for example, if arc or spot-
welding equipment is close to the control or if they share a common
power line. It can occur if flame ignition systems or electrostatic
precipitators are in the vicinity of the control.
A more common source of interference occurs when the control is
switching inductive loads such as contactor coils, solenoids or motors. The
collapse of the magnetic field when loads such as these are switched off
can create an electrical “spike” that can cause a malfunction of the
microprocessor used in the control.
Even if the control doing the switching is unaffected, a nearby control may
be affected. To eliminate or minimize this problem, transient suppressors
or “snubbers” can be employed across the inductive load.

(Inst allation continued on p age 6)
General Description
The DQ15D digital temperature
control is a programmable and
microprocessor-based controller
designed to operate two relays for
temperature control.
Features
The temperature sensor (RTD or
thermocouple) sends a signal to the
DQ15D to compare to a value
preset by the user as a Set Point
(SP). Set Points LEDs are SP1 and
SP2 on the front panel.
• In heating mode if the sensor
signal is lower than the
SP1 Set
Point value, DQ15D energizes the
SP1 relay and its isolated contacts
close.
• In cooling mode if the sensor
signal is higher than the
SP2 Set
Point value, DQ15D energizes
SP2
relay and its isolated contacts close.
• DQ15D has an optional Alarm
Condition feature. After you
activate this feature, when the
sensor signal exceeds the Alarm Set
Point, DQ15D goes into an alarm
condition. In an Alarm Condition,
both relays de-energize and the
screen displays a flashing AAA.
• The power save, night setback
feature permits the use of a second
heating Set Point to conserve
energy when required.

Wiring
This section provides wiring notes
for Power Heating/Cooling relays
and Over Temperature Protection.
Over Temperature Protection
Component failure in a temperature
controlled process can result in
damage to the product, heater over
temperature, and the possibility of a
fire. To safeguard against these
hazards, install over temperature
protection to interrupt the heater
power supply in case of low
solution level.
Process Technology heaters include a
thermal fuse standard (Protector I, II,
or III) on the heater to monitor
heater surface temperature. These
devices are designed to cut the power
to the heater in case of low solution
level. In addition to thermal protec-
tion, Process Technology strongly
recommends the use of liquid level
controls to monitor solution level
and shut off heaters prior to over
temperature conditions.
Ensure you read and adhere to all
Over Temperature Protector
Installation instructions and
warnings.
6Remove the knockouts before
reattaching the rear cover or
inserting the control in the panel.
7Insert DQ15D through the
prepared opening and slide the
retaining collar over the case from
the rear of the panel.
8Hand tighten the collar, securely
tighten the two (2) collar screws.
9Install a suitable liquid-tight
conduit fitting through the knock-out
opening following manufacturer
instructions and install field wiring.
10 Using the Power, Heating and
Cooling Relay Wiring illustration in
this chapter, install the required
input and output wires. Use
National Electric Code and local
codes for determining wire sizing,
insulation, terminations, etc.
Warning
Overtemperature protection is
required in any system where a fault
condition resulting in high tempera-
ture could produce a fire or hazard-
ous condition. Operation without
thorough safety precautions can
result in equipment failure, property
damage and personal injury.
Installation and Wiring
Typical Heater Installation only. Follow your system-specific installation instructions.

Extending Wiring
Except when wiring thermocouples,
you can extend the factory supplied
1000 ohm RTD sensor with standard
22awg or larger electrical hookup
wire. The effect of an additional 22
awg sensor wire length on the value
is approximately 1°F for every 65 ft.
Warning
When dealing with THERMO-
COUPLES, you MUST use specific
thermocouple wire when extending
the sensor wire length. Use of
incorrect extension wire can cause
hazardous operating conditions.

Warning!
Calibration procedures require the
removal of the rear cover of the control.
It also requires that power is ON,
exposing the technician to potentially
lethal voltages. Exercise EXTREME
CARE and wear tested electrician’s
gloves whenever power is on.
Equipment needed
•PCN 5416 or 5419 board.
•An NIST traceable sensor
simulator (calibrator), a precision
20 mA or higher calibrator/tester,
or a precision DMM for
verification.
Calibration Procedure
1Turn OFF all power.
2Remove rear cover.
3Remove sensor leads.
4Install appropriate sensor
calibrator, i.e. resistors or thermo-
couple simulator.
5Remove ONE lead of the 4-20
mA output wire and install the
DMM or tester in series with the
external loop and this terminal.
OBSERVE POLARITY.
6Restore power to control.
7Verify basic instrument sensor
input accuracy by simulating various
sensor inputs and observing the
display values. If out of tolerance,
perform appropriate sensor calibration
before proceeding.
8Simultaneously press and hold
and for approximately 6 sec. The
screen displays
AC.0 .While the 0 is
flashing, use to enter 33. The
screen changes to display L followed
by the current lower process limit,
i.e. 0°, -20°, 0V, etc.
9Use or to alter the lower
display value. Press
SET to store the
new value. The display will then
read hexadecimal 2AAA or 4.0mA,
verify that this is the value displayed
on your 4-20 mA calibrator/tester
or DMM.
4-20mA Output Option
The DQ15D is available with an
optional 4-20 mA output signal
proportional to the measured
(displayed) temperature. This
option is useful for source
transmitting the measured
temperature to a current loop-
sensing device such as a PLC,
remote intelligent display or chart
recorder. Use Terminals #2 and #3
for 2 wire 1000 ohm RTD.
Factory calibration is verified using
an intelligent NIST traceable 4 digit
DMM, a NIST traceable sensor
calibrator, and an intelligent display.
The factory range setting is 0-500°
F vs. 4-20 mA. Custom ranges can
be accommodated if specified at
time of order. Field calibration can
use a similar arrangement or a 4-20
mA calibrator for verification.
Since calibration is an involved
operation, it is suggested that it be
performed only after determining
that the measured values differ
from factory settings, or if the
output range is to be altered.
Use Terminals #2 and #3 for 2
wire 1000ohm RTD.

Error Conditions
Sensor values that are out of range
will generate an error display. The
temperature range is as follows:
Celsius: <-40° C or >+538° C
Fahrenheit: <-40° F or >+1000° F
Calibration Error Messages
If calibration or setup information
stored in the memory becomes
corrupt or erased, DQ15D
switches to its default calibration
and setup settings. A flashing letter
cdisplays on the left side when
DQ15D switches to default
settings. The size and position of
the letter c will define the exact
nature of the problem.
cA small c in the upper left-hand
corner indicates the control is
relying on default (factory set)
calibration values. This happens
when the control is new and has
not yet been calibrated (setup).
cA small c in the lower left hand
corner indicates the control is
relying on default configuration
values. This is a rare condition,
but may occur if the control has
been calibrated for use with a
two-wire RTD sensor but the
configuration parameters have
not been changed from their
default values. Changing any of
the configuration or Set Point
variables will turn off this
indication.
CA large C on the left side of the
display indicates default values
are being used for the
configuration and the calibration.
This can occur in a new control
that has never been calibrated or
configured, or if the memory has
been erased.

configuration of the control, the new
configuration must be saved. To save
the new value, press and simulta-
neously. This will cause the control to
store the new values internally and
then reset the unit.
Sensor DIP Switch
When using the sensor 5416 or 5447
boards, an on-board DIP switch
must also be configured.

ON OFF OFF 100 ohm RTD
OFF ON OFF voltage
OFF OFF ON current
OFF OFF OFF frequency
Note: Switching off power to the unit
before saving the new configuration will
cause all changes to be lost.
RTD Error Messages
If the screen displays one of the
following messages, the control
relay de-energized due to an RTD
condition.
HHH A thermocouple or RTD
sensor is improperly connected, or
the control read an open circuit.
UUU The RTD sensor shorted.
Note: Thermocouple shorts cause a
new junction/measurement point to be
created. This will lead to false readings
and dangerous operating conditions.
Shorted thermocouples will not result
in an error condition. Instead, incorrect
readings will be displayed.

U2, Signal Offset
This setting can be any number from -9 to +9. It represents an offset value
applied to the signal received from the sensor. Units (°C, °F, ohms) are
dictated by sensor type selected in
U1 settings.
Temperature Sensor -NumberrepresentsdegreesC orF asdeterminedbyF5 setting

U3, Output Signal Offset
U3 adjusts the optional 4-20 mA process value output. It can be any number
from -9 to +9 and is added to the signal level to cause the value to be rounded in
an intelligent receiving device. This does not affect display value.
Thisfunctionrequires eitherthe optional5416 or5419sensorboards.

Temperature Sensor -NumberrepresentsdegreesC orF,determinedby theF5 setting
VoltageSensor -Number represents tenthsof avolt(0.1VDC)
CurrentSensor -Number represents hundredths of milliamps (0.01mA)
ResistanceSignal Device -Numberrepresentsohms
FrequencySignalDevice-Setting represents hertz (counts/second)
U4, Signal Filter
This setting can be any number from 1 to 64. It represents the number of
samples taken from the sensor and maintained in memory which are then
averaged to provide an active filter of the signal. Using a small value for this
setting will cause the DQ15D to respond more quickly to sudden changes in the
sensor signal level, but will cause the unit to be more susceptible to EMI/RFI
noise. As the value increases, the susceptibility to inference reduces.
The default setting value is four (4). When sensing temperature with a 100ohm
RTD (2 or 3 wire), set the value to twenty (20) to reduce control error.
When sensing frequency signal, this setting establishes the time period for
the controller to wait for a pulse signal. Use two (2) for this value, when
measuring frequency. This causes the control to measure frequencies as low
as 1 hertz while updating the display once every two seconds.
U5, SP1 Set Point Dead Band
This setting, which may be any number from 1 to +99 represents a dead
band that only applies to the
SP1 SET POINT . This is the heat Set Point.
Thedefault andminimum forthesetting isone (1).

This bandwidth applies to the low side of the SP1 SET POINT. If the U5
setting is set at 5° F and the SP1 SET POINT is set at 115° F, then the Set Point
relay is de-energized when the (displayed) temperature reaches 115° F and it is
reenergized when the temperature falls to 110° F.
