Switching off all the outputs or individual zones will not protect any of the outputs against hazardous
voltages!
Before working on the connected heating elements, the associated connections must be unplugged, or
the entire H 1250 control unit disconnected from the mains power!
Before the H 1250 is opened, it must be disconnected from the mains power!
4. Electrical connection
The H 1225/... power/signal cable is to be used for the power and thermocouple connections between the tool and the
control unit.
If all the control zones in the H 1250 /. . . are used, it is essential to observe the following:
Maximum power consumption
H1250/1x16 …. 3600 Watt
H1250/2x16 …. 7200 Watt
H1250/4x16 …. 14400 Watt

6.1 Alarm displays
Thermocouple error
Lights continuously when a thermocouple is broken or reversed.
The actual value display shows "- - -".
If automatic actuator operation is activated, the current heating power of the controller
appears in the set point display after a short time.
Temperature deviation
Lights during the heating phase until the setpoint temperature is reached,
and if the temperature falls below the set limit temperatures.
Excess current
Lights up if the set maximum current is exceeded.
Heating circuit interrupted
Lights up in the event of a defective FF16A fuse on the module, or with a heating failure or
cable fracture.

6.2 Function displays
Set point value
Temperature display °C
Second set point value temperature reduction
Display for "lowering the set point temperature", factory setting 150°C.
The temperature can be changed with the arrow buttons.
This function is activated via the PRG button.
This requires the control unit to have been deactivated via the I/O button.
Set point value display = OFF
If the control unit is switched off and on again with the main power switch,
Previous set point is reactivated.
Third set point value temperature increase
Display for "raising set point temperature", factory setting 250°C.
This can be changed with the arrow buttons.
This function is activated via the PRG button.
This requires the control unit to have been deactivated via the I/O button.
Set point value display = OFF
If the control unit is switched off and on again with the main power switch,
Previous set point is reactivated.
Heating output
The button can be used to display the current heating output in % in the set point value
display.

8. Controller start-up
8.1 Switching on / soft start
After a careful check of the cables, connect the tool to the control unit.
Switch on the control unit at the main switch.
Use the arrow buttons to activate the set point display and enter the desired set point value.
The controller module is switched on with the I/O switch and the soft start is activated for 5 minutes
(factory setting) up to 120°C max. SOF appears in the set point value display.
The "Temperature deviation" alarm display will light up.
After the soft start has been completed, the pre-set set point value will be displayed.
The control unit now heats up the tool uniformly.

Instruction manual H1250
HASCO hot runner 11
The "Temperature deviation" alarm display will light up.
Once the set point temperature on the unit 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 5).
The soft start can be bypassed by pressing the automatic control / PRG button combination.
The automatic mode button must be pressed first in this case.
After switching the unit off and on with the mains power 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!
8.2 Manual mode
Manual mode is called up by pressing the "Manual mode" button.
The desired heating output (%) is set with the aid of the arrow buttons.
9. Programming
The programming function 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, the PRG button must be pressed for approx. 3 sec.
The control unit confirms that the changed parameters have been permanently saved by the decimal point in the top right-
hand display blinking for a short time.
The temperature control will continue to operate normally in parameter mode.
9.1. Reset all parameters / factory settings
To return all the parameters to the factory setting, the "PRG" button must be briefly pressed at the same time as the
operating voltage is switched on with the mains power switch. "RES" appears in the display.

11. Safety information
Connecting cable H 1225/... and connection housing H 1227/. . . are to be used for the electrical connections (power and
thermocouple connections) between the control unit and the tool.
This guarantees optimum control accuracy.
The control units are coordinated with HASCO's range of standard elements.
No guarantee of trouble-free functioning can be given if components from other companies are used.
Connection, repair and maintenance work may only be carried out by trained electrical technicians.
During work on the control units 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 H 1225/. . . power/signal cables must be regularly inspected for mechanical damage and replaced if necessary.
The units must be positioned so that they are free-standing, to ensure sufficient ventilation and cooling.
The control units must be protected against moisture and wet.
The units are to be used in a technically meaningful way.
Before changing the fuse, the unit must be disconnected from the mains power.
Only experienced users should operate this equipment.
