The SET menu allows you to change the operating mode and the
cartridge size of the FlexxPump 250 / 400 time. You can switch
between hour mode -h- and empty time mode Et
5.5 PRO menu
Being in operating mode hour mode -h-, you can change the break
time h as well as the number of cycles c (number of strokes).
Being in PRO menu the rst step is to set the break time h and after-
wards the number of cycles c; direct access to the number of cycles
c is not possible.
Running empty time mode Et, you can change the emptying time Et
in months.
5.6 FIL menu
This function enables you to prell connected accessories (tubes,
distributors,...) with the lubricant contained in the lubricant cartridge,
especially during the initial start-up. However, the process can also
be aborted manually at any time.

The FlexxPump 250 / 400 time can be switched off completely by
switching off the supply voltage.
The output signal at PIN 4 can be tapped for further processing
(e.g. indicator light or external control). The maximum permissible
current output must not exceed Imax < 20mA. No inductive load
(e.g. relay) may be connected!
5.8 Input and output signals

OFF switched off low, permanent
ON ready for operation high, permanent
E1 cartridge empty 0,5Hz square wave signal, permanent
E2 overload low, permanent
E3 undervoltage low, permanent
E4 fatal error low, permanent
 The FlexxPump 250 / 400 time does not process any control
signals until all errors have been eliminated.
 Error E2 (overload) must be acknowledged with switching the
pump off and on after elimination of the cause(s).
 Error E3 (undervoltage) must be acknowledged with switching
the pump off and on after elimination of the cause(s).
 IMPORTANT: There must be at least 60 sec. between switching
off and on!

3. Mounting
1. Separate the housing from the power unit by turning the retai-
ning ring counterclockwise.
2. Turn the cap on the lubricant cartridge counterclockwise and
pull it off .
3. Place the full lubricant cartridge on the
FlexxPump 250 / 400 time (label facing front). Turn the lubricant
cartridge twice clockwise onto the FlexxPump 250 / 400 time.
4. Place the dismantled housing on the FlexxPump 250 / 400 time.
Fasten the housing to the power unit by turning the retaining
ring clockwise.
5. To connect the FlexxPump 250 / 400 time with an external
power supply system add a proper connecting cable to the
electrical interface on the side of the FlexxPump 250 / 400 time.
DANGER
Damaged or flawed electrical connections or unlicensed hot
components lead to heavy injuries or even death.
4. Commissioning
1. Mechanical fastening
Fix the FlexxPump 250 / 400 time mechanically. Pay particular atten-
tion to the maximum tightening torques permissible!
2. Electrical connection
3. Power on
4. Execute FIL function
5. Hydraulic connection
Connect the consumer hydraulically to the FlexxPump 250 / 400
time. If you connect tubes to the FlexxPump 250 / 400 time make
sure that tubes and connectors are installed tightly, cleanly and
correctly.
 Ideally, use tubes prelled with the appropriate lubricant.
6. Check settings on the FlexxPump 250 / 400 time
Check the required values for the lubrication point at the factory set-
tings of the FlexxPump 250 / 400 time and adjust them if necessary.
Factory settings: operating mode=hour mode.
5. Operation and settings
Two operating modes can be selected.
Thehourmode -h- allowssettingthenumberofcycles(c)withinabreak
time (h) in hours. The cycles are evenly distributed over the break time.
Breaktimesbetween1...240hour(s)andcycles between 1...30 can be set.
The empty time mode Et allows the emptying time of the cartridge
to be set in months. Emptying times between 1...36 month(s) and cyc-
les (c) between 1...30 can be set.
