Mechanical Mounting - ASO Safety Solutions ISK 77 Manuel D'utilisation

SCE open:
Stationary safety edges for Opening direction of movement.
SCE close:
Stationary safety edges for Closing direction of movement.
ISK:
This connection is not available for the SPK 77 device variants. With the ISK 77 device variants, the SPK 55
stationary coil core is connected here.
OPEN_OUT_H, CLOSE_OUT_H:
Control output as high side switch for the Opening direction control circuit (OPEN_OUT_H) and for the Closing
direction control circuit (CLOSE_OUT_H). If the idle state is detected at the safety edges and if there are no
faults present in the device, a voltage is output at the respective control outputs (corresponds to the supply
voltage).
OPEN_OUT_L, CLOSE_OUT_L:
Control output as low side switch for the Opening direction control circuit (OPEN_OUT_H) and for the Closing
direction control circuit (CLOSE_OUT_L). If the idle state is detected at the safety edges and if there are no
faults present in the device, the respective control output is pulled to Gnd potential.
OPEN_OUT1, OPEN_OUT2:
Control output for the Opening direction for the ISK 77 R and ISK 77 W variants. If the idle state is detected at
the safety edges for the Opening direction and if there are no faults present in the device, the switch-on state
is output (ISK 77 R: connections short-circuited, ISK 77 W: approx. 8.2 kΩ between the connections).
CLOSE_OUT1, CLOSE_OUT2:
Control output for the Closing direction for the ISK 77 R and ISK 77 W variants. If the idle state is detected
at the safety edges for the Closing direction and if there are no faults in the device, the switch-on state is
output (ISK 77 R: connections short-circuited, ISK 77 W: approx. 8.2 kΩ between the connections).
TST_MOD, TST_SIG, TST_COM:
By applying a separate voltage to the TST_MOD connection against TST_COM, the mode for requesting
the test is selected. Applying a separate voltage to the TST_SIG connection against TST_COM controls the
external test request according to the selected mode.

7. Mechanical mounting

Mechanical mounting of the safety relay is to be performed professionally at a suitable mounting location.
The provided assembly instruction are recommendations only. The actual arrangement of the individual
components depends on the design of the gate in question and the conditions at the installation site.
The switching unit must not be mounted in the immediate vicinity of strong sources of heat.
The switching unit may be mounted in any orientation. To prevent moisture penetration, it should, however,
be installed so that the cable conduits point downward.
The procedure for constructing the ISK system can be found in the separate assembly instructions.
