Lights up during the heating phase until the setpoint temperature has been
reached.
Is constantly lit if the set limit temperatures are exceeded or not reached.
Alarm output active.
Excess current
Lights up if the set maximum current is exceeded.
Alarm output active.
Heating circuit interrupted
Lights up in the event of a defective fuse FF16A on the module, heating failure or cable fracture.
Alarm output active.

6. Controller start-up
6.1 Switching on / soft start
After a careful check of the cables, connect the mould to the control unit.
Switch on the control unit at the main switch.
Use the arrow buttons to activate the setpoint display and enter the desired setpoint value.
The controller module is switched on and off with the I/O button and the soft start activated.
SOF appears in the setpoint value display. After the soft start has been completed, the setpoint value that was
entered will be displayed.
The control unit now heats up the mould uniformly, drying out moist heating elements.
The "Temperature deviation" alarm display will light up.
Once the setpoint temperature that was entered has been reached, production can be run with the calculated
parameters.
The "Temperature deviation" alarm display will go out.
If malfunctions occur during start-up, the reason for the error will be shown by the appropriate displays on the
control unit (see Page 6).
The soft start can be bypassed by pressing the automatic control / PRG button combination.
The automatic control button must be pressed first in this case.
After switching the unit off and on with the mains switch, the soft start will be active again.
The soft start can be permanently deactivated via parameter 17 (page 8).
Note! The soft start provides protection for the electric components.
It is recommended to run a soft start!

6.2 Open-loop control
Manual operation is called up by pressing the "Open-loop control" button. The desired heating output (%) is set
with the aid of the arrow buttons.
7. Programming
Programming mode is activated by pressing the PRG button (for about 3 sec.).
The first menu item "P00" appears in the actual value display. The setpoint value display shows the value of the
parameter.
This can be changed with the arrow buttons.
Pressing the PRG button twice again will call up the next parameter.
To exit program mode, press the PRG button for approx. 3 sec.
The control unit confirms that the changed parameters have been permanently saved through the decimal point in
the top right-hand display blinking for a short time.
The temperature control continues to operate normally in parameter mode.
7.1. Factory settings
To return all the parameters to the factory setting, keep the "PRG" button pressed when the operating voltage is
switched on.

10. Safety information
Connecting cable Z 1225 /. . . and connection housing Z 1227/. . . are to be used for the electrical connections
(power and thermocouple connections) between the control unit and the mould.
This will ensure optimum control accuracy.
The control units are coordinated with the HASCO standard components range.
If parts from other manufacturers are used, perfect operation cannot be guaranteed.
Connection, repair and maintenance work may only be carried out by trained electrical technicians.
During work on the control unit and on the cables, devices, machines and tools connected to them, all parts must
be disconnected from the mains power.
The system must also be safeguarded against being unintentionally turned on again.
The power/signal connectors Z 1225 /. . . must be regularly inspected for mechanical damage and replaced when
necessary.
The units must be free-standing to ensure sufficient ventilation and cooling.
The control units must be protected against dampness and wet.
The units are to be used in a technically meaningful way.
Before changing the fuse, disconnect the unit from the mains power.
