Manual commissioning
(s. chapter 10.2)
•
Ensure secure connection between valve and actuator.
•
To activate the individual commissioning push button B1 for minimum 7 seconds.
•
For manual operation use push buttons B1 and B2 until the required open valve position is reached.
•
Start commissioning of both positions and store them by simultaneously pushing the buttons B1 and B2 for
minimum 3 seconds.
•
After successful commissioning, the green LED is flashing 7 times.
•
Push button B1 to return to normal operation.
•
After successful commissioning, check the found or adjusted stroke by comparing the set value and the valve
position.
•
In case of unsuccessful commissioning the green LED is flashing quickly. Please check valve mounting.
•
For commissioning, a stroke of at le
ast 1 mm in direction “close with force” is required before the actuator has
reached its mechanical stop. Furthermore, the actuator must be able to perform a stroke of at least 5 mm.
10.6
Manual operation
(s. chapter 10.2)
10.6.1 Buttons
•
Push button B1 and B2 simultaneously for minimum 3 seconds to change to manual operation mode.
•
Push button B1 to retract valve stem.
•
Push button B2 to extend valve stem.
•
Push button B1 and B2 simultaneously for minimum 3 seconds to exit from manual operation mode.
10.6.2 Handwheel
•
Press the handwheel towards the housing: the motor is deactivated.
•
Keep the handwheel pressed and turn it:
o
to the left: the valve spindle moves downwards.
o
to the right: the valve spindle moves upwards.
•
Release the handwheel: the handwheel is inoperative, after 5 seconds the motor is reactivated.
11. Operation
The operator of an electrical system in a potentially explosive atmosphere must keep the equipment in proper
condition, operate it properly, monitor it and carry out maintenance and repair work. See also IEC/EN 60079-17 /
IEC/EN 60079-19.
During operation, all internal parameters, such as the required motor torque and the current position, as well as the
operating states of the drive are permanently monitored. This ensures that the actuator is positioned with optimum
accuracy and that the valve is always closed correctly.
Cut-off in end positions
Depending on the setting of the DIP switch S2.1, the end position switch-off takes place in operation in one end
position at the position found/selected, in the other end position by force. (s. chapter 10.2).
12. Commissioning
•
Before the first commissioning, the equipment must be checked for its suitability in the
corresponding zone on the basis of its marking. The values indicated on the type plate and in
the applicable documents must not be exceeded. Open the cover (s. chapter 8.), put the
actuator on the valve (see chapter 7.), connect the electric supply (s. chapter 9.).
•
Open the cover (see chap. 8), place the actuator on the valve (see chap. 7), make the electrical
connection (see chap. 9). (see chap. 9).Perform automatic (s. chapter 10.5) or manual
(s. chapter 10.6).
•
Close the cover (s. chapter 8.).
