Description:
• The lubricator’s sensor pin detects whether a cartridge is screwed onto the lubricator.
The amount of lubrication in the cartridge is not detected.
• Error E2 interrupts running dosing sequences and prevents further control signals.
• Error E2 is displayed until a cartridge is screwed on; the error need not be acknowledged.
NOTE
An opened cartridge may not be screwed on again. Only full cartridges may be
installed because the counter is reset by removing a cartridge
