15.2 Checking the setting of the limit switching
.
Set selector switch to position OFF (0) (figure 34).
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 31).
.
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 33, subclause 20.2.
15.4 Checking the PTC tripping device (option)
.
Turn selector switch to position TEST (wiping) (figure 35).
If the PTC tripping device is working properly, the tripping of the motor pro-
tection is signalled 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 36):
The fault signal is reset if the device is working properly.
In case the selector switch position TEST does not initiate a fault signal, the
wir
ing and the selector switch have to be checked by the AUMA service.
If no other options (clauses 16. to 18.) require setting:
.
Close switch compartment (see page 31, clause 19.).
