In adjustment, follow the paragraphs “VERIFICATION of APPARATUS FUNCTION And its LOCATION”,
“fitting on VALVE” and “ADJUSTMENT of ACTUATOR with VALVE” of these instructions.
For safety reasons, the system is delivered in the state of induced error of Calibration when the functions are
limited in order to reduce the risk of damage to the actuator by wrong wiring.
Record of position CLOSED, OPEN and AUTOCALIBRATION
– The actuator must be adjusted in such a way that the recorded position would switch off the actuator before it is
switched off by torque. For tight closure, the torque relay for torque Closed is only connected into the control circuit.
The actuator can be shifted either manually or electrically. The actuator in version CONTROL can be started from
menu MOTOR in program DMS2. In this case, the actuator does not react to the set position and can only be
stopped by the torque relay. In controlling from menu MOTOR, no torque may be induced. The torque must be left
manually.
If, during adjustment, the torque is reached in the end-limit position, the torque must be left by means of a hand
wheel.
– The actuator is set to position Closed and position Closed is stored by long pressing of push-button C
(without
entering the Menu).
– The actuator is set to position Open and position Open is stored by long pressing of push-button O.
– The calibration routine is started by means of push-button P
(in remote control) that, in the three-position
regulation, will measure actual inertial masses of the system and store them into the memory of the control
unit. In the two-position regulation, pressing of push-button P only cancels the error of Calibration.
– In recording the end-limit positions, signalling relays and the position transducer are also set.
– In case the actuator stroke is to be increased and the switching off is set to “from position”, the actuator will
switch off during shifting in position O or 100 %. To further change the position, press C or O, and, while
keeping it depressed, the actuator can be further shifted. After required position is reached, it is stored to
memory by pressing push-button C or O.
Parameters that can be changed by user are set by manufacturer as follows:
1. Tripping torques:
100 % or required value (it is not recommended to change the value
without consulting the supplier of the valve, etc.).
2. Relay 3 and relay 4: signalization SZ 1 % and SO 99 % of stroke
3. Time of blocking: 2 – 8 s according to rate of actuator shifting
4. Position of blocking: 5 % of stroke from end-limit positions (it is not recommend to change
the value by more than 10 %)
5. Characteristics of position transducer: closed 4 mA, open 20 mA
6. Relay READY: w not remote
In version CONTROL:
1. Setting of control signal:
closed 4 mA, open 20 mA
2. Insensitivity of actuator in regulation: 1 % (it is not recommended to set insensitivity higher than 3 %)
3. Response in case of loss of control signal: stop
4. Way of switch off in end-limit positions: PO + PZ
