General notes on installation

• Check the cable entries and dummy plugs for tightness.

• Tighten the hood screws so they are all equally tight.

• Continuously overloading and blocking the drive will damage
it.

• Spark-quenching capacitors may adversely affect the drives'
direction of rotation and result in damage.

Cable entries

• When storing, installing and commissioning the servomotor,
care must be taken to ensure that the cable entries have been
properly sealed. Only cables appropriate for the diameter of
the cable entries must be used.

Installing the hood

• When installing the hood, you must ensure that the O-rings
underneath the hood screws and the O-ring in the drive
housing are properly seated.

• The connection face of the hood must not show any signs of
damage.

• Tighten the hood screws equally.

Housing/Hood

• No additional bores may be drilled into the drive housing or the
hood.

The servomotor may only be fitted by a qualified
specialist.

When a gas dosing system with servomotor is
ordered, the servomotor is installed on the gas
dosing system ready for connection.

Electrical connection

See Section 5.2.4 for warnings and notes relating to
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.

Warning
The internal wiring of the drive must never be

modified.

Close the hood again and tighten the hood screws.

5.2.3 Checking the tightness of pressure gas lines

Caution

Note

Note

English (GB)

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).

Warning
Maximum nitrogen pressure 16 bar!
Danger of damages and chlorine break-out when

being exceeded!

• 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!
