Function
Service for the power supply of the detectors. The native 24VDC voltage can be
loaded up to a maximum of 100 mA.
Triggering the application process according to configuration. The trigger signal can
be delivered by a photocell or PLC. The impulse must have 10-30 VDC, a duration of
at least 50ms and the correct polarity. The input is protected against polarity rever-
sal. The current is limited by a protective resistor (2.2 k). The transition from an
inactive status (no current flow in the optocoupler) to the active state (current flow in
the opto-coupler) is recognized as a trigger signal (leading edge).
Function corresponds to the [START] button (comp. Fig. 6-3 page 40) on the control
panel and can be switched for the remote activation using a potential-free contact.
Switch the input against the ground (GND) of the labeller.
This input corresponds to the [Reset] button (comp. Fig. 6-3 page 40) on the control
panel and can be switched for the remote activation using a potential-free contact.
Only switch the input against the ground (GND) of the labeller.
Function
general error. Output from the READY/ALARM relay. The signal is active (READY =
N.O.; ALARM = N.C.), if all of the following points are met:

[START] button has been pressed

Operational readiness of the printer, regardless of any pending print jobs.

Printer currently not in the pause mode (for PAX).

Labels and ribbon available.

Operating pressure is within the defined pressure range.
