8.3.1 Error E1 (empty level) - External control (PLC)
The integrated microelectronics of the FlexxPump 125 is equipped with an automatic
counter which counts the number of dispensing operations after a new and full car-
tridge has been tted. For a cartridge with 125ml lubricant there are 780 strokes, for a
cartridge with 250ml lubricant there are 1560 strokes. The small mathematical dieren-
ce is considered as protection against the entering of air into the hydraulic system. This
ensures that the empty status message (error E1) is transmitted to the external control
(PLC) in time. For this purpose, a separate, unique output signal is provided, which can
be easily and reliably detected by the external control (PLC).

Description:
The FlexxPump 125 is properly connected to an external controller via the electrical
interface and connected to the power supply.
The Pulse-Control-Mode PUL is activated on the FlexxPump 125, E1 is displayed in
the LCD and the red LED lights up.
Error E1 (Empty state signal) can only occur immediately after a donation.
Error E1 (Empty state signal) must and cannot be acknowledged. Remedial action is
described in chapter 9.2.
At the same time as removing the cartridge, the FlexxPump 125 sends a permanent
low level (0 V) as output signal to PIN 4.
The FlexxPump 125 does not process control signals until all errors have been
eliminated.
