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).
