15.2 Checking the setting of the limit switching .
Set selector switch to position OFF (0) (figure U-1).
The controls’ power supply is maintained in position OFF.
.
Move actuator manually into both end positions of the valve.
.
Check if limit switching is set correctly for both end positions. Hereby observe
that the appropriate switch is tripped in each end position and released again
after the direction of rotation is changed. If this is not the case, the limit
switching must be set again.
When limit switching is set correctly:
.
Set selector switch to local control ( I ) (figure S).
.
Perform test run at the local controls via push buttons OPEN - STOP -
CLOSE.
15.3 Checking the type of seating
The valve manufacturer states whether switching off in the end positions should
be by limit switch (limit seating) or torque switch (torque seating).
.
For checking the setting, refer to page 35, subclause 20.2.
15.4 Checking the PTC tripping device (option)
.
Turn selector switch to position TEST (wiping) (figure U-2).
If the PTC tripping device is working properly, the tripping of the motor protec-
tion is signaled via the collective fault signal (refer to wiring diagram) and via
the fault indication light on the local controls.
.
Turn selector switch to position RESET (wiping) (figure U-3):
The fault signal is reset if the device is working properly.
