Description:
• If an error occurs on the lubricator, it transmits a low-level signal to the controller on PIN 4.
This signal must be present without interruption for at least 4 seconds before the error message
can be acknowledged.
• The 10sec 24 V signal (9.9 s ... 10.1 s) can then be transmitted to the lubricator.
• After the signal drops to 0 V the error is cleared and the LCD displays CLr.
If an error had occurred during the execution of a control signal, this sequence will be resumed after
rectification of the error.
