comfortable connection of a hand-held terminal. All clamps for fixed wiring to
the control are located at the rear side of the connection module in the control
cabinet.
VAC 30.2 and VAC 05.1: The connection module VAC 30.2 and VAC
05.1 for hand-held terminals with stop button is equipped with a
fine thread screwed plug at the front side. For the VAC 30.2 connec-
tion module, the integrated "automatic stop button jumpering" al-
lows temporary integration of the hand-held terminal into the safety
circuit of the running machine without accidental stopping the ma-
chine.
VAC 31.1: Hand-held terminals with red-yellow EMERGENCY STOP
pushbuttons can only be temporarily integrated into the safety cir-
cuit if the plant is in safe state or if a certified jumpering mechanism
is available. The connection module VAC 31.1 is equipped for such
devices with a bayonet ending with additional short-circuit connec-
tor. The hand-held terminal may be only connected if the plant is in
safe state. Plugging or unplugging a hand-held terminal during the
operation would immediately set the system to standstill.
The connection modules depend on the safety components of the hand-held ter-
minal:
