 5.7 Three electrodes and one float switch
English (GB)

Use CU 211 in systems with three electrodes and one float switch
in applications such as tank filling. The pump is controlled by the
liquid level in the tank.
– The electrode, pos. 1, is a reference electrode.
– When the electrode, pos. 2, no longer registers liquid, the
pump is started.
– When the electrode, pos. 3, registers liquid, the pump is
stopped. It is possible to set a stop delay which delays the
stop of the pump.
– When the float switch, pos. 4, is lifted up by the liquid, the
high-level alarm is activated.
– The pump can be stopped by means of the manual on/off
switch, pos. 5.

The three electrodes may be replaced by float

Note
switches.

5.7.1 DIP switch setting

English (GB)
The DIP switch settings apply to CU 211.
• Switches 1, 2 and 3: System type

This setting encodes the system type.

CU 211: Three electrodes and one float switch in a tank filling system.

• Switch 4: Start delay and automatic test run

This setting activates a start delay in the range from 0 to 255 sec. (random) after the power supply has been
switched on.
Automatic test run is carried out every 24 hours.

This setting causes the pump to start immediately after the mains supply has been switched on.
No automatic test run.

• Switches 5, 6 and 7: Stop delay

The stop delay is the time from the stop signal is given until the pump is stopped.
The pump must not run dry.

0 sec. 60 sec.

15 sec. 90 sec.

30 sec. 120 sec.

45 sec. 180 sec.

• Switch 8:

Switch 8 has no function in connection with this system type, but keep the setting in this position.

• Switch 9: Alarm resetting

This setting ensures that alarm signals from external alarm devices and the built-in buzzer are reset
automatically. However, an alarm signal will only be reset if the cause of the fault no longer exists.

At this setting, the alarm signal must be reset manually by means of the reset button.
See section 2.1.1 Resetting of alarm.

• Switch 10: Restarting

This setting enables automatic restarting after the motor PTC resistor/thermal switch has caused the pump to cut
out. However, restarting will not happen until the motor has cooled off again.
Warning
When the pump(s) connected is (are) used in potentially explosive environments,
switch 10 must not be set to this position.
This setting requires the pumps to be restarted manually after the motor PTC resistor/thermal switch has caused
the pump to be cut out. Reset by means of the ON-OFF-AUTO selector switch.
Warning
When the pump(s) connected is (are) used in potentially explosive environments,
switch 10 must not be set to this position.

19
 5.8 Flow switch
English (GB)

Use CU 211 in systems controlled by a flow switch in applications

such as draining systems. The pump is controlled by the flow in
the discharge line.
– The pump is stopped when the flow switch, pos. 2, registers
that there is no liquid flow.
– When the pump has stopped, a settable start delay sets in,
and after that the pump will try to restart. The restart attempt
will be interrupted when the settable dry running time has
elapsed if the flow switch still does not register flow.
– The pump can be restarted manually by means of the
switch, pos. 1.

TM04 2754 2908

5.8.1 DIP switch setting

English (GB)
The DIP switch settings apply to CU 211.
• Switches 1, 2 and 3: System type

This setting encodes the system type.

CU 211: Flow switch in a draining system.

• Switches 4, 5 and 6: Dry running time

The dry running time is the time the pump is allowed to run after start even if the flow switch registers no flow.
The pump is stopped again if the flow switch still does not register flow.

10 sec. 2 min.

20 sec. 3 min.

40 sec. 4 min.

1 min. 5 min.

• Switches 7, 8, 9 and 10: Start delay

The start delay is the time from the pump stopped until the pump attempts to restart.

No restart * 15 min.

1 min. 17 min.

2 min. 20 min.

3 min. 25 min.

5 min. 30 min.

7 min. 50 min.

10 min. 70 min.

12 min. 90 min.

* If the DIP switch was set to "no restart", the pump kan only be restarted by means of the switch.
