10.4.4.14 Checking the bearing noise
The bearings of the drive motor and the compressor
must be checked for unusual running noise, espe-
cially in comparison to previous maintenance. Recur-
rent vibration measurements are recommended.
10.4.4.15 Checking the solenoid valves
for capacity control
See the following sections in the start-up chapter:
•
"Checking the control slide adjustment"
•
"Checking the control slide adjustment times"
10.4.4.16 Checking the oil heater
Check the electrical function using a clamp-on
ammeter.
Check the outer temperature of the oil separator and
compare with the temperature of the machine room
(while the screw compressor package is at a stand-
still).
10.4.4.17 Maintenance of the compres-
sor drive motor
Hint!
The compressor drive motor must be
maintained in accordance with the
"Motor documentation".
Maintenance of the compressor drive motor includes
the following activities:
– Lubrication of the motor
Lubrication intervals and quantities according to
the "Motor documentation" or "Type plate".
–
Cleaning of the motor (externally)
Select a suitable cleaning agent according to the
"Motor documentation".
10.4.4.18 Checking the start regime
See the operating manual of the compressor control
system.
10.4.4.19 Checking the safety devices
See section entitled "Checking the fault monitoring"
in the start-up chapter.
The safety devices are checked by moving to the
switching points (limiting values). For details, see
also the operating manual of the compressor control
system.
Limiting value = parameter list
Moving to the switching point is achieved by throt-
tling the pressure-side stop valve.
10.4.4.20 Checking the operating parameters
Hint!
The operating parameters are checked via the TouchPanel. The checking intervals recommen-
ded in the table must be observed. The project-related setting values and limits are given in
the parameter list.
Inform the manufacturer contract partner if the parameters are outside the allowable limits.
