Set SW1-1 and SW1-2 both to OFF. Connect the 24V DC (+) to the SIGNAL [+] and the ground to
GALV [-]. For example, a PLC can supply this type of voltage pulse (this depends on the type of PLC).
STOP :
Input for interrupting coding
This input must be grounded with a potential-free contact or an NPN open collector. Connect the
wires to J3, PRE EXT and GROUND. The maximum current which will run is 30 mA. The coding unit
remains at temperature. When the contact is opened again, the HQC will be ready to resume coding
after about 1 second.
With this input the packaging machine, for example, can start/stop coding.
Outputs:
Signal busy with printing
This signal is grounded as soon as the cylinder is activated. This
output is an open collector which can switch 24V DC 30 mA. The connection you use is on J3,
called PRINT. It is used to synchronise the HQC with the packaging machine, if the packaging
supports this.
Preheating signal
As soon as the STOP button on the Control Panel is activated or the STOP
input is triggered, this output is grounded. This output can switch 24V DC, 30 mA.
Heating signal
This output is grounded as soon as the heating element is activated. This signal goes
down to the zero throughputs of the mains voltage. This output can switch 24V DC, 30 mA. A pulse
train can therefore be observed by using a pull-up resistor to, for example, the 24V CC. The pulse
train is present when the red TEMP light is illuminated. This output can be used, for example, by an
intelligent PLC with a high speed counting input. In this way the PLC can monitor the heating function
of the hot printer.
