6.1 Auto-test RUN
The Auto-test function can be used to switch on the
pumps when these have been turned off for a long
time.
The pumps are switched ON by the clock or after a
set period of inactivity (c24).
How to start the auto-test: activation by clock
(c24=1)
If the pumps are running, the auto-test is put on hold
and this text is shown on the display in blinking
mode:
tSt
When the pumps are in standby, the auto-test starts
and the test in progress and the pump in use are

ing the OK button.
What does the auto-test do?
Auto-test activated by clock time
The Auto-test function involves the following settings
and sequences:
1. Enabling the function (c24=1)
2. Setting the day, hour, minutes of the test (h26,
h27, h28).
3. Switching ON pump P1 after the set time.
4. Stopping pump P1 after the set time (h29).
5. Waiting for a minute
6. Switching ON pump P2.
7. Stopping pump P2 after the set time (h29).
Auto-test activated after period of inactivity
The Auto-test function involves the following settings
and sequences:
1. Enabling the function (c24=2)
2. Setting the inactivity time for Pump 1 (t24) or
Pump 2 (t25).
3. Switching ON Pump P1 after the set time (t24).
4. Stopping pump P1 after the set time (h29).
5. Waiting for a minute
6. Switching ON Pump P2 after the set time (t25).
7. Stopping pump P2 after the set time (h29).
The Auto-test is interrupted if the pressure or the
level in the system changes, requiring the pumps to

6.2 Starting and stopping the pumps (pa-
rameter c14)
The following description is valid when the sewage
software is enabled (parameter c02=0). If filling is
enabled in the parameter (c02=1), the start and stop
functions are reversed.
6.2.1 Float switches
The pumps are switched on and stopped by the float
switches. Various options are provided.
0=G1 and G2
Pump 1 is switched ON and stopped by float switch
G1.
Pump 2 is switched ON and stopped by float switch
G2.
1=G MIN
Pump 1 is switched ON by float switch G1.
Pump 2 is switched ON by float switch G2. Both
pumps are stopped by G MIN. The high level alarm
is activated by G MAX but neither of the pumps is
switched ON.
2=G MAX
Pump 1 is switched ON and stopped by float switch
G1.
Pump 2 is switched ON and stopped by float switch
G2.
The high level alarm is activated and both pumps are
switched ON by G MAX. Pump 2 is switched ON
after 2 sec. This option is to prevent excessive and
rapid filling of the tank.
3=G MIN+G MAX
Pump 1 is switched ON by float switch G1.
Pump 2 is switched ON by float switch G2.
Both pumps are switched ON by G MAX. Pump 2 is
switched ON after 2 sec. The high level alarm is ac-
tivated by G MAX. This option is to prevent exces-
sive and rapid filling of the tank. Both pumps are
stopped by G MIN.
6.2.2 Electric probes
Pumps are switched on and stopped by electric level
probes. Various options are provided.
Common probe "S COM" has to be connected.
0=S1 and S2
Pump 1 is switched ON and stopped by probe S1.
Pump 2 is switched ON and stopped by probe S2.
1=S MIN
Pump 1 is switched ON by probe S1.
Pump 2 is switched ON by probe S2.
Both pumps are stopped by probe S MIN. The high
level alarm is activated by probe S MAX but neither
of the pumps is switched ON.
