Error message: General
The following causes may lead to a general error message (the list is not exhaustive):
- counterpressure in the hydraulic lines is too high
- destroyed electronic component on PIN 4 due to electrical overcurrent
- internal error in the FlexxPump
If a general error message is active, the FlexxPump issues the following signal on PIN 4:
For blocked hydraulic lines or other errors, the FlexxPump issues a Low (+0V) signal on PIN 4 lasting more than 30 seconds. The output signal at PIN 4 is High (+20...30V) during normal operation. During an actual motor run of the FlexxPump, the signal switches to Low (+0V). Normally this takes between approx. 9 and 18 seconds, depending on the length of the hydraulic hoses and the viscosity of the lubricant. Afterwards, the signal switches back to High.
Malfunction | Cause | Measure |
|---|---|---|
Lubrication system does not lubricate | The measured counterpressure was too high three times in a row. Hydraulic connections or hoses may be blocked, hoses too long, and/or lubricant too stiff/hard. | Remove cause of the counterpressure, switch off the power supply to the FlexxPump and switch it on again. The fault is set to zero. The FlexxPump starts up again. |
