o oil viscosity
o oil temperature
o adjusted vacuum
o length and cross section of the suction line
o position of the IFPM/S relative to the reservoir
In exceptional cases, for example at very high tanks, the vacuum
chamber can overflow. This can be detected, if oil comes out at the separator. In
these cases it is suggested to throttle the suction line, for example with the inlet
ball valve.
5. Failure messages
• In case of malfunction of a component, the system will shut off and one of the following
messages will appear in the display:
- No oil
- Overflow
- Filter clogged
- No lubricating oil in v – pump
- Motor overload hydraulic pump
- Motor overload vacuum pump
5.1. No oil
• This message will be displayed if no fluid reaches the lowest level switch after a certain
amount of time. The reasons for this error could be the following:
- high viscosity
- small diameter of the suction line or too long suction line
- suction height to high
- closed inlet ball valve
- contaminated solenoid valve
