Version STM.. (cable entry M20x1.5/NPT ½“, see
rating plate)
Fit the cable gland with the appropriate degree of
protection.
For pin assignment see Figure 2.
Tighten the screws with a torque of 0.5 Nm.
Check that the cable entry is sealed.
Close the cover and screw in position.
Functional Check
Warning! Danger of fatal injury as a result of faults
in installation and functional check.
Before carrying out the functional check, make sure
that there are no persons in the danger area.
Observe the valid accident prevention regulations.
After installation and any fault, the safety function must
be fully checked. Proceed as follows:
Mechanical function test
The actuator must slide easily into the actuating head.
Close the safety guard several times to check the
function.
Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
Guard locking by solenoid force: Activate guard
locking.
The machine must not start automatically.
It must not be possible to open the safety guard.
3. Enable operation in the control system.
It must not be possible to deactivate the guard locking
as long as operation is enabled.
4. Disable operation in the control system and deactivate
guard locking.
The safety guard must remain locked until there is no
longer any risk of injury.
It must not be possible to start the machine as long as
the guard locking is deactivated.
Repeat steps 2 - 4 for each safety guard.
Inspection and Service
If damage or wear is found, the complete switch
and actuator assembly must be replaced.
Replacement of individual parts or assemblies is
not permitted!
No servicing is required, but regular inspection of the
following is necessary to ensure trouble-free long-term
operation:
correct switching function
secure mounting of components
dirt and wear
sealing of cable entry
loose cable connections.
Safety switches STM must be exchanged completely after
2 millions operating cycles.
Note:The year of manufacture can be seen in the bottom,
right corner of the rating plate.
Exclusion of Liability under the Following
Conditions:
if the unit is not used for its intended purpose
non-compliance with safety regulations
non-compliance with safety regulations
failure to perform functional checks.
