GUDEL FlexxPump4 D - Fig. 5 -13 Switching Time Diagram: General Error

5.5.3.3 General error
The following causes may lead to a general error (the list is not exhaustive):
• Overpressure in the lubrication line
• the voltage supply does nit lie within the specified parameters (undervoltage/overvoltage)
• Internal fault in the lubrication system
If there is a general error, the lubrication system issues the following signal on PIN 4:

For general errors, the lubrication system issues a Low (+0 V) signal on PIN 4 lasting more than 3 seconds. The output signal on PIN 4 is High (20...30 V) during normal operation. During an actual mo-
tor run of the lubricating system, the signal switches to Low (+0V). Normally this takes between about 7 and 17 seconds, depending on the length of the lubrication lines and the viscosity of the lubri-
cant. Afterwards, the signal switches back to High.
