6. Commissioning
Conditions:
●
The fail safe unit was mounted to the valve:
➭ page 33,
●
All electrical cables are connected:
➭ page 33,
●
The type of seating (limit or torque seating) and the tripping torque (torque
switching) have been set in the actuator to suit the mounted valve.
-
For detailed information on the customer-specific version, refer to the order-
related data sheet.
- The “Type of seating” and “Torque switching” settings are described in
the operation instructions pertaining to the actuator.
Commissioning of the overall combination of actuator (gearbox), FQM and valve is
made as follows:
1. Perform initialisation:
➭ page 24, Initialisation
2. Set end stops:
➭ page 25, End stops in the fail safe unit
3. Perform reference operation (adaptive end position setting):
➭ page 26, Reference operation (adaptive end position setting)
6.1. Initialisation
If all prerequisites starting the initialisation phase are fulfilled, initialisation starts
automatically to put the combination consisting of actuator (gearbox), FQM and valve
in ready for operation state.
Further information: ➭ page 29, Indications during and after initialisation .
Prerequisites for starting initialisation:
●
Power supply applied.
●
Actuator controls are ready for operation (booted after power supply connection).
●
+24 V DC is applied at
ESD
input (refer to wiring diagram).
●
Actuator controls are in operation mode Local or Remote (selector switch position
on Local control or Remote control).
●
The fail safe unit is in the configured fail safe end position.
(The end position switch
LSO/LSC of fail safe unit must be operated.)
Sequence for initialisation
A constant force spring is wound within the fail safe unit thanks to the electric motor
acting as mechanical energy buffer for the fail safe operation. Simultaneously, the
actuator runs into the configured fail safe end position to make sure that both actuator
and FQM fail safe unit are in the same position as the valve.
Information
●
Clicking noises during initialisation or the fail safe operation are normal and do
not represent a fault.
●
For repeated FQM tripping (fail safe operation), a pause of minimum 15 minutes
must be obeyed after the fourth fail safe operation to allow motor cool down.
After successful initialisation, the FQM fail safe unit is ready for further commissioning,
for standard operation as well as for fail safe operation.
