DLS FlexxPump 125 Quick Start

The FlexxPump 125 DLS only processes the control signals listed

in the table up to a maximum length of 14 seconds. If a high level
(+24 V DC) exceeds the defined tolerance level, the FlexxPump 125
DLS does not react. If a high level (+24 V DC) is applied to PIN 2
of the electrical interface for longer than 15 seconds the LCD will
display --- and the FlexxPump 125 DLS does not react.
Control signal 2 seconds
Immediately after the control signal drops the motor run of the
FlexxPump 125 DLS starts and 0.16 cm³ lubricant is conveyed to the
outlet. Simultaneously, the FlexxPump 125 DLS sends a low level
output signal to the external controller (PLC) to confirm the duration
of the motor run.
In order to ensure a reliable and unambiguous recognition of

the control signal a break must be observed. The control signal 2
seconds requires a break time of at least 22 seconds between two
identical or different control signals.
Control signal 12 seconds
The control signal 12 seconds triggers the FIL function by the
external control.
Control signal 14 seconds
The control signal 14 seconds is used to acknowledge error
messages of errors E2 and E3.

Additional character on the LCD
Displayed when the cartridge is empty and needs to be
replaced.
MAX After each cycle the maximum back pressure is displayed
in bar.
The FlexxPump 125 DLS does not process any control signals until

all errors have been eliminated.
Error E2 (overload) must be acknowledged with the control signal

14 seconds after elimination of the cause(s).
Error E3 (undervoltage) must be acknowledged with the control

signal 14 seconds after elimination of the cause(s).
6. Maintenance
NOTICE
A used lubricant cartridge must not be replaced on the FlexxPump
125 DLS as the integrated stroke counter of the FlexxPump 125
DLS is automatically reset by the cartridge sensor after a cartridge
has been removed. Only use full lubricant cartridges.
