- REMOTE MACHINE ALARM SIGNAL
The unit is fitted with a relay that is activated whenever a machine alarm condition arises. The contact of this relay, which is
normally open when no alarm is present, is connected to the two terminals for the remote signal. Refer to the machine’s wiring
diagram.
The voltage that can be applied to these terminals must not exceed 24V. This voltage must be taken from a transformer with separate
primary and secondary windings, in compliance with the legislation in force. The maximum current value is 1.1A at AC11.
