Electrical connection
1. Unscrew the hood screws and remove the hood.
2. Establish the electrical connections in accordance with the
circuit diagram; see fig. 20.
– Connect terminals 18, 19 and 20 in accordance with
requirements; voltage < 50 V.
3. Determine the direction of rotation and, if necessary, correct it.
Determining the direction of rotation
The internal wiring means that the direction of rotation (looking
through the drive towards the output shaft) and limit switches are
assigned as follows:
If the mains voltage is present at terminal 2, the output shaft
rotates anticlockwise (in the direction "open/max.").
– This direction of rotation is restricted by the upper switch
(max.). If the switch is activated, the mains voltage is
present at terminal 4.
If the mains voltage is present at terminal 3, the output shaft
rotates clockwise (in the direction "close/min.").
– This direction of rotation is restricted by the lower switch
(min.). If the switch is activated, the mains voltage is present
at terminal 5.
If the drive rotates in the opposite direction to the control
commands, swap over the connections of terminals 2 and 3.
Close the hood again and tighten the hood screws.

Warning
Check the tightness not until the total plant is ready
for start-up.
Danger of chlorine break-out!
Note
More possible reasons for insufficient operating

5.2.3 Checking the tightness of pressure gas lines
Pressure gas lines are all lines from the gas containers to the
vacuum regulator.
If the plant is equipped with a nitrogen rinsing device:
Check tightness roughly with nitrogen.
Detailed checking with amonia.
Checking the tightness with nitrogen
Close all container valves
Open container connection valves and all shut-off valves up to
the gas dosing system
Open the connection valve of the nitrogen cylinder
Slowly open the valve of the nitrogen cylinder, until the lines
have a pressure of about 10 bar (read at the manometer of the
vacuum regulator).
Apply soap water to all components under pressure
– Formation of bubbles and/or pressure drop at manometer:
Leakage in pressure lines!
Depressurize the plant!
Eliminate leakage!
Check tightness again!
No formation of bubbles, pressure at manometer does not drop
significantly within one hour: Pressure lines are tight.
Checking the tightness with ammonia
Open all container valves and container connection valves and
quickly close them again
Slowly pass the open ammonia bottle along pressure-gas
leading parts
Formation of white mist: Leakage in pressure lines!
Depressurize the plant!
Eliminate leakage!
Check tightness again!
Fig. 27 Formation of white mist: Leakage in pressure lines!
– No formation of white mist: Pressure lines are tight.
Fig. 28 No formation of white mist
Fig. 29 Danger of leakages
5.2.4 Servomotor tests
5.2.5 Checking the servomotor's direction of rotation
The servomotor is controlled by an external controller. This
means that the servomotor's direction of rotation depends on the
controller's cabling and settings being correct.
Warning
Maximum nitrogen pressure 16 bar!
Danger of damages and chlorine break-out when
being exceeded!
TM04 0849 0908TM04 0697 0908
Warning
Liquid ammonia must not come in contact with parts
of the plant!
Danger of leakages by corrosion!
TM04 0698 0908
Warning
The drive may only be commissioned if the hood and
cable entries are properly closed.
Warning
Please note that the process of commissioning the
drive will cause associated fittings/levers/rodding to
move.
Warning
Check that all the emergency equipment/functions on
your installation are working correctly.
Warning
Once all adjustment work has been completed,
check that the drive and the fittings/levers, etc.
operated by it are working correctly.
Warning
Never work with a damaged drive.
Caution
When commissioning, all the installation's
components must be ready for operation.
Note
Follow the installation and operating instructions for
the components used.
Note
Observe the installation and operating instructions
for the controller and the gas dosing system.
