13.2 Setting
Systems for parallel operation with 3 levels (4 electrodes),
page 100.
The module CU 214 has a 10-pole DIP switch in the bottom right
corner, see fig. 11.
Note:
During setting, the controller must be off circuit for at least
1 minute to ensure the correct configuration during start-up after
change of the DIP switch setting.
The DIP switch setting offers the following possibilities:
•
selection of starting delay and automatic test run (switch 4),
•
setting of stop delay (switches 5, 6 and 7),
•
selection of automatic alarm resetting (switch 9),
•
selection of automatic restarting (switch 10).
Fig. 11
Set the DIP switch as shown in fig. 11.
Each individual switch (1 to 10) of the DIP switch can be set to
position OFF or ON.
Note:
The DIP switch
must
not
be set to other switch combina-
tions than those described in this section.
Set the switches 1 to 10 as follows:
•
Switches

,
2
and
3
, application type:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
•
Switch

, starting delay and automatic test run
(only in the case of battery back-up):
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
•

This setting determines the actual application type
(par-
allel operation with 3 levels (4 electrodes), page 100)
.
At this setting, the start-up is delayed within the range
from 0 to 255 sec. (random) after the electricity supply
has been switched on
when
the liquid level is suffi-
ciently high.
Automatic test run carried out every 24 hours.
After the electricity has been switched on, the pump will
start immediately
when
the liquid level is sufficiently
high.
No automatic test run.
The
stop delay
is the time from the stop signal is given until the
pump is stopped.
It must be ensured that the pump is not running dry.

Switch 8 has no function in connection with the actual
application
(parallel operation with 3 levels
(4 electrodes), page 100)
, but this setting
must
be
maintained!
This setting ensures automatic resetting of alarm
signals to external alarm devices and the built-in
buzzer. 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 (the reset button is
described in section
).
This setting enables automatic restarting after the motor
thermal switch has cut out the pump. Restarting will not
be carried out until the motor has cooled to normal
temperature.
When the pumps connected are used in explosion
hazard areas, switch 10
must not
be in this
position!
At this setting, the pump must be restarted manually after
the motor thermal switch has cut out the pump. To restart
the pump, push the ON-OFF-AUTO selector switch into
position OFF for a short period (the ON-OFF-AUTO
selector switch is described in section
When the pumps connected are used in explosion
hazard areas, switch 10
must
be in this position!
