5.4.6 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:

Fig.5-11 Switching time diagram: Error message: General information
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 viscos-
ity of the lubricant. Afterwards, the signal switches back to High.
