Coupling guard has been disassembled.
1.
Take the measurements at the circumference of the cou-
pling in two planes with a 90° offset.
2.
Check the light gap towards the outer diameter using a
straightedge (1):
Position the straightedge over both coupling halves.
Adjust the motor if you detect a light gap at the outer
diameter (
Motor adjustment, page 17).
3.
Check the gap size using a feeler gauge (2):
Permissible gap size (
Dimension drawing, page 46
et seq.).
Use a feeler gauge to measure the gap (A) between
the coupling halves.
If the measured gap size is impermissible, adjust the
motor (
Motor adjustment, page 17).
4.
Install the coupling guard.
5.9 Motor
adjustment
1.
Adjust the motor in a way which ensures that the coupling
halves are accurately aligned and use adjustment shims if
required.
2.
Check the motor adjustment.
3.
Repeat the adjustment process if height or angular offset
have not yet been fully compensated.
4.
Then, tighten the motor screws.
5.10 Electrical connection
RISK OF ELECTRIC SHOCK
Risk of death from electric shock!
►
Any electrical works must be carried out by qualified electri-
cians only.
►
Observe the IEC 30364 (DIN VDE 0100) and for potentially
explosive areas the IEC 60079 (DIN VDE 0165) standard.
DANGER
Risk of death from rotating parts!
►
Make sure to only operate the aggregate with all covers
(fan hood) installed.
5.10.1 Motor
connection
Observe the manufacturer's specifications for the motor.
1.
Connect the motor in accordance with the circuit diagram.
2.
Exclude any risk associated with electric power.
3.
Install an Emergency-Stop button.
5.10.2 Checking direction of rotation
DANGER
Risk of death from rotating parts!
►
Use protective equipment when carrying out any works on
the aggregate.
►
Keep an adequate distance to rotating parts.
CAUTION
Risk of material damage caused by dry running or incorrect
direction of rotation!
►
Pump filled with operating liquid up to the middle of the
shaft (
Filling, page 18).
1.
Switch the aggregate on and immediately off again.
2.
Check whether the direction of rotation of the motor is in
accordance with the arrow indicating the direction of rota-
tion on the aggregate.
Wrong direction of rotation may result in damage and es-
cape of operating liquid at the mechanical seal.
RISK OF ELECTRIC SHOCK
Risk of death from electric shock!
►
Any electrical works must be carried out by qualified electri-
cians only.
►
Observe the IEC 30364 (DIN VDE 0100) and for potentially
explosive areas the IEC 60079 (DIN VDE 0165) standard.
3.
In case of deviating direction of rotation: Swap the two
phases.
