connection of the Hand-held Terminal IndraControl VCH 08.1 via the connec‐
tion module IndraControl VAC 30.2 without causing an unintended stopping of
the plant.
NOTICE
Before commissioning the IndraControl VCH 08.1 do observe that the stop but‐

Functionality of the stop circuit jumpering
Fig.7-5: Stop circuit jumpering
If the Hand-held Terminal IndraControl VCH 08.1 is not plugged in, the contacts
K1.1 and K1.2 of relay K1 in the IndraControl 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 operation.
If the 17-pin connector of the IndraControl VCH 08.1 is screwed on the Indra‐
Control VAC 30.2 connection module, NC contacts ST1.1 and ST1.2 are
switched in the stop circuits via leading contacts. The IndraControl VCH 08.1
is still without voltage supply and the stop button has no effect.
If the 17-pin connector is completely screwed on the connection module, relay
K1 switches and supplies the IndraControl VCH 08.1 with voltage via NO con‐
tact K1.3. Simultaneously, by opening contacts K1.1 and K1.2 the stop circuit
jumpering is deactivated. The stop circuits are active, the control is ready for
operation, and the stop button is integrated in the stop circuit.
