The IndraControl VEH 30.2 is provided with a 2-circuit, 3-stage enabling de‐
vice, which is operated by two actuators integrated in the housing. It consists
of single switching elements and can be used in safety circuits up to catego‐
ry 3 (EN ISO 13849-1), if the evaluation is appropriate. For this purpose the
two circuits have been electrically isolated and designed in a redundant man‐
ner.
In operation modes with enabling device one of the both actuators of the
IndraControl VEH 30.2 has to be consciously held in the central switch posi‐
tion. Releasing or firmly pushing through the actuator causes the stop of dan‐
gerous movements. When moving back from the pushed through position to
the inactivated position, there is no enabling signal.
A further safety operating component of the IndraControl VEH 30.2 is a 2-cir‐
cuit stop pushbutton. The switching contacts are directly guided outwards via
the connecting cables and can be connected via the IndraControl VAC 30.2
connection module. The automatic stop circuit jumpering allows to loop in the
hand-held terminal without interruption. The operation of the plant can be
stopped in all operation modes with the stop pushbutton (stop category 0).
The enabling device is activated by one of the both actuators. These actua‐
tors are attached at the left and right side of the device and are mechanically
coupled in a manner that it is not possible to activate them simultaneously.
The enabling device of the IndraControl VEH 30.2 is designed according to
"safety technology". The enabling button must be connected to the control in
a manner that the requirements for electrical circuits for safety purposes ac‐
cording to EN 775, EN 60204, EN 13849-1, EN 1088 and VDI 2854 are fulfil‐
led. A succeeding control has to fulfill the monitoring of the switch according
to the standards and regulations valid for the respective machine and/or in‐
stallation.
Because of its proper wiring with the safety contactors of the drive control,
dangerous movements can only be executed in certain operation modes
(e. g. installation mode or test mode), if the enabling device is hold in the cen‐
tral (= enabled) position. The enabling circuit on its one must not trigger dan‐
gerous movements. For this, the following commands are required:
Provide a time- or clock-dependent limitation of the enabling func‐
tion.
These movements are immediately stopped if there is no activation or in
completely pushed through position (panic position). Switching back from the
panic position means that the device switches electrically directly to the inac‐
tivated position. A new movement is only started after entering the corre‐
sponding commands with new enabling.
