8.3.2 Error E2 (overload) - external control (PLC)
Error E2 (overload) signals a hydraulic overload during a dispensing process, e.g. if the
maximum pressure is exceeded.
Description:
LUB-V is properly connected to an external controller via the electrical interface and
connected to the power supply.
LUB-V has been successfully controlled by the external control (PLC) immediately
before the occurrence of error E2 and has (attempted to) perform a dispensing operation.
Pulse control mode PUL is activated on LUB-V, E2 is displayed in the LCD and the red
LED lights up.
l
When the maximum permissible pressure is reached during or after a dispense,
LUB-V sends a permanent output signal as low level (0 V) to PIN 4 for external control
(PLC).
l
The error E2 (overload) must be acknowledged with the control signal 14 seconds
(chapter 8.2.3) after elimination of the cause(s).
LUB-V does not process any control signals until all errors have been eliminated.
