Fig.12-3: STOP circuit bridging
If the hand-held terminal is not plugged in, the contacts K1.1 and K1.2 of re‐
lay K1 in the VAC 30.2 connection module keep the stop circuits 1 and 2 of
the control closed. The STOP circuits are active; the control is ready for oper‐
ation.
If the 17-pin connector of the hand-held terminal is screwed on the VAC 30.2
connection module, NC contacts ST1.1 and ST1.2 are switched in the STOP
circuits via leading contacts. The hand-held terminal is still not supplied with
voltage and the STOP pushbutton has no effect.
If the 17-pin connector is completely screwed on the connection module, re‐
lay K1 switches and supplies the hand-held terminal with voltage via N/O
contact K1.3. Simultaneously, by opening contacts K1.1 and K1.2 the STOP
circuit bridging is deactivated. The STOP circuits are active, the control is
ready for operation, and the STOP pushbutton is integrated in the STOP cir‐
cuit.
The VAC 30.2 connection module must be permanently supplied with voltage
(24 V) via pin 1 X1.1 or pin 1 X1.2. To ensure that the STOP button is inte‐
grated, a voltage monitoring has to be provided at this point. The connected
hand-held terminal can be supplied via pin 3 X1.1 or pin 3 X1.2 with 24 V.
