Function
X54. connector. Basic control signals
Male 4-pin connector located at the front of the unit and identified as X54.
Female aerial plug connector with a push-in connection supplied as an
accessory. The basic control signals are sent through it.
The following table shows the main data of the aerial connector and the wire
to be connected:
Pinout
Pin description
When the control circuit is supplied with +24 V DC (A18 connector) the
module runs an internal test. If it runs OK, it closes the status QC-BPM
OK status contact · pins 3 and 4 ·.
This contact stays closed while the supplied +24 V DC are maintained
and internally the module runs properly.
The consumption of these control signals is between 4.5 and 7 mA.
Installation
See section, 8.6.10 CONNECTIONS FOR BASIC CONTROL SIGNALS.
