Inadmissible operating methods
Installation on uneven and / slanting foundations.•
Securing transport devices to the acoustic hood, e.g. using eye bolts in the accou-•
stic hood element, winding ropes without expansion braces etc.
Non-observance of operating data.•
Non-observance of maintenance intervals.•
Incorrect direction of rotation.•
Switching on - during run-down.•
- during reverse rotation.•
Inadmissible increase in pressure.•
Remaining under or exceeding maximum rotational speed.•
Exceeding the maximum temperature.•
Pole change to lower rotational speed before motor has come to a standstill.•
Operating without a properly connected fault indicator / control is not permited. •
Risk of total machine damage!
Operation without assemblies or with damaged assemblies which serve for the •
protection of persons and machine.
Overlling the maximum oil level.•
Operation without oil.•
“Reasonably foreseeable misuse” that can result from easily forseeable
human behaviour:
Operating the machine without having lled the lubricant.•
Operating the machine with too much lubricant.•
Operating the machine with reduced intake performance, e.g. due to a soiled •
intake lter, starting strainer etc.
Assembly and commissioning of the rotary piston machine with intake-side and/or •
discharge-side ange sealers, protection covers or similar.
Insufcient ventilation at the installation site, no insulated lines.•
Open re or sparks created by welding, separating or similar in direct proximity to •
the unit. Risk of re!
Operating the machine without an isolated protective device, open belt or coupling •
drive.
Risk of injury from rotating components!•
Taking out the transport securing pin under the hinged motor support during ope-•
ration.
Only applicable for belt drive machines.•
VM compressor •
Continuous operation of the compressor where �i = 4 and there is a differential
pressure of < 2 bar.
VML compressor •
Continuous operation of the compressor where �i = 2.3 and there is a differential
pressure of < 1 bar.
