Safety information
Before working on the plant, you must ensure that it is safely isolated from the voltage supply. Turn the equipment switch OFF
and remove the mains plug. Connection, repair and maintenance works may only be carried out by qualified personnel.
Before commissioning, the plant must be checked in accordance with EN 60204 (11:1998) and the recognised rules of sound
engineering. High temperatures arise at the connected components. Relevant precautionary measures are to be taken on
commissioning or rather during operation.
Application:
This control system from EWIKON can be used to operate EWIKON hotrunner systems in dry industrial rooms.

Introduction
After switching on the supply voltage, the controller displays the initialisation information is displayed followed by the first
combination of the display menu (c.f.. Page 5). The power output is switched off.
The controller is operated using the 4 "Shift", "UP Arrow", "DOWN Arrow" and "Select" keys.
The display consists of two 4-digit 7-segment displays, the upper (larger) one usually shows the actual value or the parameter
name, the lower (smaller) one usually shows the
setpoint value or the parameter setting.
Furthermore, diverse LEDs are available
for displaying the:
- Operating mode (230V / 5V)
- Correct supply voltage (POWER)
- Standby (ON flashes) or
heating mode (ON continuously lit)
- Faults (ERROR)
- Increase mode ( ) or Decrease mode ( )
- Fuse failure (FUSE)
The key functions are kept
the same in all menus:
- The "Shift" key is used to switch between
the 2 different basic menus "Display” and
“Command", if the key is pressed for
> 2 seconds the parameter menu appears.
Pressing the Shift key in the "Error Messages"
sub-menu automatically acknowledges the error
and returns the display to the normal
display menu.
- The arrow keys are used to change values
and to switch commands On or Off. Changes
in values are automatically accepted after
2 seconds (display flashes until then),
commands are accepted directly, without a
waiting period. The old value is retained if you
page forward before accepting the value.
- The "Select" key is used to page forward within
a menu, e.g. to the next display combination or
to the next command. In the parameter menu the
"Select" key has an additional function:
After entering a valid password and pressing the Select key for > 2 seconds, the user arrives at the 1st parameter level.
If the password entered is also valid for the next level, pressing the "Select" key for > 5 seconds brings the user to the
2nd parameter level.
The sequence structure is sketched in the overview diagram on Page 5.
After approx. 30 seconds of no key being pressed, the last display menu combination is automatically shown.
Any access right set is reset after approx. 5 minutes of no key being pressed.
The setpoint values in the display menu are identified by the following preceding characters (units):
-"C" for temperature setpoint value
-"P" for percentage setpoint value 230V operation
-"A" for ampere setpoint value 5V operation
In the case of the actual values only the percentage and ampere values are preceded by the units,
not the actual temperature value.
If the temperature sensor is defective (interruption), "500" is displayed instead of the actual value.

Operation and adjustment of the controller
The controlled is adjusted in 4 different menus, whereby the focus is on the "Display" and the "Command" menus. If configured
correctly, all the controller operations (Switch On and Off, increase or decrease mode, changes to setpoint values) can be carried
out in these two menus.
The configuration is set in the "Parameter menu", where the basic settings (temperature control or control mode, 5V or 230V
operation, increase and decrease values) can be made. The operational performance of the controller can be significantly
influenced in the lower parameter levels, which can only be reached by entering a password.
If faults are identified, the "Error messages" menu is called up, if several errors occur, these can be displayed consecutively.
The error messages can only be called up from the "Display menu", display of the error messages is suppressed during
configuration and command input.
The menus are described in detail in the following chapters.
Display menu
Three different displays are possible in the display menu, the required combination is chosen using the "Select" key.
Depending on the display selected, the following pairs of values are shown:
1) Display of actual temperature value and the setpoint value of the operating mode set (closed-loop or open-loop control),
the possible displays are e.g.:
- for closed-loop control, 230V or 5V: " 250"
"C.250"
- for open-loop control, 5V: " 250"
"A. 80"
- in case of sensor break: " 500"
"C.250"
In this display, it is possible to change the setpoint value using the arrow keys.
2) Display of actual temperature value and manipulated variable of the power output, in percent (230V) or ampere (5V)
depending on the type of hotrunner.
3) Display of the actual temperature value and measured current value of the power output.
In 230V operation, this value equates to the power consumption of the connected heating, it is displayed with a resolution
of 0.1A (e.g. display: "A 1.5"). The channel heat output can be easily calculated or checked using the formula "P = U * I"
(where: P = heat output, U = mains voltage, I = power consumption).
In 5V operation, the displayed value equates to the power consumption of the downstream load transformer (primary side),
the value is displayed in a resolution of 0.01A (e.g. display: "A2.13").

7
Command menu
All the functions required for the operation can be activated or deactivated in the command menu, the required command is
chosen using the "Select" key. The "UP Arrow" and "DOWN Arrow" keys are used to switch the various functions On and Off.
1) "Ctrl" "Off/ On", switch the hotrunner On or Off
The heating mode is switched on using the "UP Arrow" key and off using the "DOWN Arrow" key. If the hotrunner is switched
off, "Off" appears in the display, and "On" if the hotrunner is switched on. Parallel to the input in the command menu, it is also
possible to switch the controller On and Off via the digital inputs. To do this, the 24 V DC signal socket must be connected
accordingly, see Chapter "Connector and connection assignment" on Page 15. Furthermore, the controller is also fitted with a
self-optimising function, to optimally adjust the control response to the connected heating load. In this way, both extremely fast
nozzles and slow or time lag manifolds can be precisely controlled. The necessary settings for the various types (PID
temperature control, see Section "Parameter level 1") are permanently stored in the controller, these are automatically selected
by the controller during a "learning phase".
To do this, after the controller is switched on, a defined output power is given on the heating load for a certain period of time,
depending on the heating performance, the control parameters are then adapted to the controlled system. However, the
optimisation phase is only carried out if the actual temperature lies below 100° C when the hotrunner is switched on and the
"Opti" parameter in the 1st parameter level stands at "1" (delivered condition).
2) "Ctrl" "InDe", switch increase (increment) and decrease (decrement) mode On or Off
The increase function is switched On or Off (alternating function) using the "UP Arrow" key, the "DOWN Arrow" key is used
accordingly for the decrease function. Priority is always given to a decrease adjustment. Parallel to the input in the command
menu, it is also possible to switch the increase or decrease mode On or Off via the digital inputs of the controller. To do this,
the 24 V DC signal socket must be connected accordingly, see Chapter "Connector and connection assignment" on Page 15.
In increase mode a maximum time limit continues to act to prevent a continuously excessive temperature level.
After the set time of the "tInc" parameter in the 1st parameter level has expired (delivered condition = 600 seconds), the
increase mode is automatically aborted, if it has not been quit manually beforehand. The maximum time limit function for the
increase mode is switched Off with the setting "0 seconds".
3) "Ctrl" "Save", Save function for the set values
Inputs or changes in values are first stored in the non-volatile memory (RAM) of the controller and is used as the current
operating setting. Only after a save function is this data written to the non-volatile memory (EEPROM), and is then available
later, even after the supply voltage has been switched Off and On. During the save function, the increase and decrease LEDs
flash alternately, the controller does not accept any further inputs during this time. The save can only take place if the
hotrunner is switched off, not while the heating mode is running.
The process can either be triggered manually in the command menu or automatically after the hotrunner is switched off.
To this end, the "Save" parameter in the 1st parameter level must be set to "1" (delivered condition).

8
Parameter menu
The basic configuration of the controller can be adjusted in the parameter menu, so that only the display and command menu
are required for the actual operations. Changes to the controller's operating performance can continue to be made in the lower-
lying parameter levels. The required setting can be chosen using the "Select" key, the changes to the values are made using the
arrow keys.
1) "Mode", Temperature-control operating mode ("C") or manual open-loop control ("P" or "A")
Select the operating mode of the connected hotrunner, either temperature control (Select "C" for °C) or open-loop control.
In open-loop control mode, a differentiation is made between 5V operation (Select "A" for current control) and 230V operation
(Select "P" for percentage value control). The input for the setpoint, increase and decrease values is made in "°C" (C), in
percentage (P) or in amperes (A) respectively depending on the parameter "Mode" and "Type" settings. In the delivered
condition, the temperature control operating mode is set.
2) "Type", hotrunner type "5V" or "230V"
Select the operating voltage of the connected hotrunner; "5V" or "230V", for 5V operation the controller must be equipped
with an appropriate transformer (e.g. 1-zone controller 5V/230V, Art. No. 68010.201). The selected setting is signalled by
the two LEDs below the display.
ATTENTION: The "Type" parameter cannot be adjusted if the hotrunner
(heating mode) is switched on!
3) "CInc" / "PInc" / "AInc", increase value for the current operating mode
The increase value equates to a 2nd setpoint value for the closed-loop or open-loop control circuit, e.g. to set a higher
temperature level for a brief time while starting up to make it easier to open the hotrunner. The value entered is added to
the setpoint value of the increase function is switched on. The increase mode can be switched On and Off via the command
menu or the digital signal input.
Possible setting ranges for the increase value are:
- for automatic (closed-loop) mode: 0...200°C
- for controlled (open-loop) mode: 0...50% or A
4) "CDec" / "PDec" / " ADec", decrease value for the current operating mode
The decrease value equates to a 3rd setpoint value for the closed-loop or open-loop control circuit, e.g. to set a lower
temperature level for a brief time in case of malfunctions to avoid burning the material. The value entered is subtracted
from the setpoint value if the decrease function is switched on. The decrease function can be switched On and Off via the
command menu or the digital signal input.
Possible setting ranges for the decrease value are:
- for automatic (closed-loop) mode: 0...200°C
- for controlled (open-loop) mode : 0...50% or A
5) "PASS", Password for access to the other parameter levels 1 and 2
Enter the password to be able to make changes in the other parameter levels 1 and 2.
The access authorisation is automatically reset if no keys are pressed for 5 minutes.
ATTENTION: Some of the settings which can be made in the other access levels have a severe effect on the
operating performance of the controller. The values should therefore only be changed by trained,
expert personnel!

Tolerance band monitoring ("tbOn", "tbC1" - "tbC4", "tbA1" - "tbA4" and "tbdy")
Tolerance band monitoring enables automatic monitoring of the injection moulding process with respect to compliance with the
setpoint values entered. In this way, various reciprocal actions can be triggered in the open communications network with the
injection moulding machine, e.g. decreasing the hotrunner in case of machine faults or interruption to the injection operation in
case of faults in the hotrunner. To do this however, the link between the control device and the machine must be made via the
24V signal cable, Art. No. 60070.019.
The monitoring function is switched On by the "tbOn" = "1" parameter (delivered condition "0").
Tolerance band windows can be entered for temperature ("tbC1" to "tbC4") and current ("tbA1" to "tbA4"), furthermore it is also
possible to set a release time lag ("tbdy", delivered condition "0 minutes"). This is used for delayed switching off of an error
message in case of tolerance band deviations, to allow the hotrunner system sufficient time after the heating up phase to
develop an adequately stable thermal condition.
There are two pairs of limiting values each available for the temperature and the current monitoring, this enables a differentiation
to be made between warning messages (in case of slight deviations) and fault messages (in case of larger deviations). The set
limiting values apply relative to the set setpoint value, so that if the latter are changed the tolerance band values are automatically
adjusted accordingly. The warning messages and fault messages are displayed in the error messages.
Drying function ("Cdry", "Pdry" and "tdry")
A drying phase is always run through in 230V heaters following the switching on process to remove any residual moisture in
the hotrunner system. Here the controller works in phase angle control mode, to avoid damage to the connected heating loads.
Compared to the pulse package mode used in normal mode, smaller voltage peak values are shifted to the heating in phase
control, thereby avoiding arcing due to moisture.
In the drying phase the heaters are controlled with an adjustable maximum output ("Pdry", delivered condition "50 %") for a
minimum period ("tdry", delivered condition "600 seconds") to a preset maximum temperature ("Cdry", delivered condition
"120 °C"), only then is the setpoint value entered started up.
The drying phase is bypassed if the actual temperature value is above the set drying temperature when the control device is
switched on.
Ramps function ("Crmp", "Armp" and "Prmp")
When switching on the hotrunner system or if changes are made to the setpoint values, the ramp set determines the slope or
speed (change per second), with which the new setpoint value is started up. This makes it possible to influence the heating speed
of the hotrunner system. When making the adjustment, it should be remembered that sluggish heating loads, e.g. manifolds,
cannot achieve rapid temperature changes due to physical restrictions.
Separate adjustment possibilities are available for each of the operating modes temperature control ("Crmp", delivered condition
"1°C / second"), current control 5V operation ("Armp", delivered condition "2A / second") and percentage value control 230V
operation ("Prmp", delivered condition "5% / second).

11
PID temperature-control ("t-vp", "t-tn", "t-tv" and "Load")
The HPS-C control system is equipped with a PID control algorithm, which guarantees optimum control performance and small
deviations between the actual and setpoint value during operation. During the system's heating up phase, special additional
supporting functions act, as the connected controlled system (hotrunner) performance mostly deviates here from the subsequent
operation.
The "Load" type is determined in the normal case by the controller itself for each channel and depends on the type of heating
connected. In total, a sub-division is made into 10 different types, for each of which certain controller presets are stored in the
system. The following table shows reference values for the various settings, although the controller can contain deviating values:
Load type Hotrunner type t-vp (amplification) t-tn (reset time) / s t-tv (lead time) / s
0 230V, very slow performance 25.00 150.0 0.5
1 230V, slow performance 20.00 120.0 0.4
2 230V, average performance 15.00 90.0 0.3
3 230V, fast performance 10.00 60.0 0.2
4 230V, very fast performance 5.00 30.0 0.1
5 5V, very slow performance 1.10 60.0 6.4
6 5V, slow performance 1.05 48.0 6.4
7 5V, average performance 1.00 36.0 6.4
8 5V, fast performance 0.95 24.0 6.4
9 5V, very fast performance 0.90 12.0 6.4
If necessary, the control characteristics can also be adjusted manually, if the automatic identification does not achieve a good
controlled result. Here, either the load type can be changed, whereby the settings stored in the system are automatically
accepted. Alternately, it is also possible to individually adjust each of the 3 control parameters.
Thermocouple type ("tC")
The HPS-C controller temperature measurement is designed for the connection of a thermocouple, in total, 3 different types of
thermocouple can be connected. When the device is delivered, the type Fe-CuNi "L" (setting "2") according to DIN 43710 is set;
the types Fe-CuNi "J" (setting "1") and NiCr-Ni "K" (setting "0") according to DIN IEC 584 can also be used.
The assignment of the setting and thermocouple type is listed in the following table:
Setting Thermal element Type Sleeve colour *) Plus leg *) Minus leg*)
0 NiCr-Ni K green green white
1 Fe-CuNi J black black white
2 Fe-CuNi L blue red blue
*) Colour coding of the thermocouple connection cable, deviations from this are possible.

Parameter level 2
Parameter level 2 is only accessible to the manufacturer. However, the possible settings and limiting values are listed here for
information purposes. Parameter level 2 is reached by pressing the "Select" key for at least 5 seconds in Parameter level 1,
if the valid password has been entered.
The following lists the parameters which can be changed in this level in tabular form.
Display Designation Unit Min value Max value Preset value
"CLdn" Lower temp. set limit °C 50 150 50
"CLup" Upper temp. set limit °C 250 500 450
"ALdn" Lower current set limit A 10 50 10
"ALup" Upper current set limit A 50 125 125
"PLdn" Lower percentage set limit % 0 25 0
"PLup" Upper percentage set limit % 50 100 100
"ILim" Maximum current 5V A 50.0 125.0 125.0
"I-vp" Current control P component - - - - - 0.00 5.00 0.40
"I-tn" Current control I component Sek. 0.0 30.0 6.0
"I-tv" Current control D component Sek. 0.0 10.0 6.4
"IMdn" Lower measured value current calibration A 10.0 50.0 10.0
"ICdn" Lower adjustment value current calibration A 10.0 50.0 10.0
"IMup" Upper measured value current calibration A 100.0 150.0 100.0
"ICup" Upper adjustment value current calibration A 100.0 150.0 100.0
Set limits ("CLdn", "CLup", "ALdn", "ALup", "PLdn" and "PLup")
The setpoint values for the corresponding operating modes can only be changed within the specified limits.
This means that the available adjustment range can be limited, e.g. for critical materials.
The limiting values can be changed within the ranges given in the table.
Maximum current 5V ("ILim")
Here the maximum current can be limited in 5V operation, e.g. to avoid damage to critical hotrunner systems. The controller
complies with this limiting value in temperature controlled and in current controlled mode.
Current control parameter ("I-vp", "I-tn" and "I-tv")
Apart from the temperature control, the controller also has a current control with PID characteristic, which is used in 5V operation.
If necessary, the control parameters can be optimised here manually.
Current calibration ("IMdn", "ICdn", "IMup", "ICup")
In certain cases, it can be necessary to adjust the recording of the measured current values in 5V operation, e.g. if an 8V type is
used in place of the transformer with 5V output voltage (for high heating conductor resistances). Here both the rate (slope) as well
as the level of the measuring range can be changed, however, a separate current measuring device (clip on amperemeter or
multi-meter with current clamp) and with appropriate accuracy must be available for the calibration.
The measured controller values which have been read off at the lower and upper point of the measuring range are entered as
the lower and upper measured value. The values which were measured at the same position using the separate current
measuring device are entered as the lower and upper calibration values. The calibration should be carried out at 10A and 100A,
so that the measuring inaccuracy is kept as small as possible over the whole working range.

Error messages
Apart from the normal operating functions, the HPS-C control system also provides other extensive monitoring functions in order
to identify problems or errors in the hotrunner system or in the controller at an early stage.
Errors or warnings are displayed in the "error messages" menu, if the hotrunner system (heating mode) has been switched on,
the fault and warning message output is also set and the red "ERROR" LED is switched on.
If several errors have been identified, these can be displayed consecutively by pressing the "Select" key. The "Shift" key is used
to return to the display menu and the error is thus automatically acknowledged. If the cause of the error is not found and removed,
the error message is displayed again after approx. 5 seconds.
In case of error messages, "Err" is always overlaid in the lower line, the corresponding error designation is displayed in the top
line. The displays have the following meanings:
