·
Check whether the connecting flange clings to the valve/gearing.
·
Fix the flange with four screws tightened to allow moving of EA. Then the fixing screws tighten
uniformly crosswisely.
2.1.2 Electric connection and checking of function
Follow up with connecting the EA with mains or master system.
1. Follow instructions in the part "Requirements for professional qualification"!
2. While laying electrical line abide by the instructions for heavy current installations.
3. Cables to terminal boards or connectors lead through screw bushings.
4. Before initiation ES into operation internal and external protection terminals are needed to be
connected.
5. Feeding cables are to be fixed to the solid construction at most 150 mm from the bushings.
Checking of supply connection
·
Connect a supply cable to the actuator and check whether phases are connected properly.
·
Press the button SB2 "open" on the control board. The output stem should move
counterclockwisely looking to the output shaft from the control chamber.
If the power supply is reversed it is necessary to press the button "stop" and change phases
connection. Then perform the check again.
Checking of the torque switches
·
Press the button SB2 "open" on the control board. The output shaft should move in the direction
"open".
·
Press the lever (42) in the direction to the output shaft, what switches contacts (20) MO (S1) and
the actuator should stop.
·
Press the button SB1 "closed" on the control board. The output shaft should move in the direction
"closed".
·
Press the lever (42) in the direction from the output shaft, what switches contacts (21) MZ (S2)
and the actuator should stop.
Checking of the position switches
·
Press the button SB2 "open" on the control board. The output shaft should move in the direction
"open".
·
Press the spring (36) to switch contacts of the switch (37) PO (S3) and the actuator should stop.
·
Press the button SB1 "closed" on the control board. The output shaft should move in the direction
"closed".
·
Press the spring (36) to switch contacts of the switch (37) PZ (S4) and the actuator should stop.
Checking of the indication switches
The indication switches are ordered as additional equipment. If not agreed else they are
adjusted to operate next before positions "open" and "closed".
2.2 Dismantling
Before dismantling it is required to disconnect the EA from mains!
Do not connect and disconnect live connectors!
·
Disconnect the EA from mains.
·
Disconnect the leads from the EA terminal boards and loosen the cables from bushings. Pull out
the connectors in case of the connector version.
·
Loosen the fixing screws of the EA flange and disconnect the EA from the valve/gearing.
·
While sending the EA to be repaired put it into a package solid enough to avoid damages of the
EA during transportation.
