The following table shows the configuration possibilities. The display's top line shows the
option, the bottom line is the value that can be changed.
1. Line in display
Configuration
option
Explanation
Basic load ON
0 – 200 (500) cm
This value establishes the switch-on point for the first pump
Basic load OFF
0 – 200 (500) cm
This value establishes the switch-off point for the first pump
Peak load ON
0 – 200 (500) cm
This value establishes the switch-on point for the second
pump
Peak load OFF
0 – 200 (500) cm
This value establishes the switch-off point for the second
pump
High water
0 – 200 (500) cm
When the configured value is transgressed, the common fault
report relay and the high water relay will switch
Running time max
0 – 60 sec.
The value 0 deactivates this function. If the value is set between 1-60
min. the pump shuts off if the set operating time has been exceeded
without interruption
Run time altern.
Is deactivated
1 – 60 min
When the configured time is transgressed in basic load mode,
there will be a pump change.
Start delay
0 – 900 sec.
After loss of power, the pumps won't start until after the
configured time has passed. The display shows the remaining
time.
Stop delay
0 – 180 sec.
The basic load pump will continue to run after transgressing
the shut off point until the configured time has ended.
Interpump Delay
0 – 60 sec.
When both pumps are triggered, then the 2nd pump won't turn
on until after the configured time has passed.
Force activation
Is deactivated,
1 – 10s
Is activated = When the pumps are not triggered for 24 hours,
then they will automatically run for the configured
Acoustic alarm
Is deactivated,
is activated
Is activated = when there is an error, the internal piezo buzzer
will sound
Intermitt. alarm
Is deactivated,
is activated
Is activated = The error report relay is clocked.
Instead of a blinking light, a more economical solid light can
be used.
Pump alternation
Is deactivated,
is activated
Is activated = After each use of the basic load pump, there will
be a change to the other pump.
P1: therm fault 1
Is deactivated,
is activated
Is shut off = On block 31, 32 (pump 1), no bimetal contact
(warning contact) is connected.
P2: therm fault 1
Is deactivated,
is activated
Is shut off = On block 38, 39 (pump 2), no bimetal contact
(warning contact) is connected.
ATEX mode
Is deactivated,
is activated
Is activated = If no liquid is configured via level detection, then
the pumps cannot be started. This applies for the manual
function, as well as for 24-h switch on and remote control
systems.
Service mode
is activated,
Is deactivated
Is activated = All settings can be modified
Is shut off = Settings can be displayed, but cannot be modified
Level control
Internal converter
(optional)
Float switch
4 – 20 mA Interface
Level detection via dynamic pressure or bubbler system
Level detection via float switch
Level detection via external sensor (4 - 20 mA)
20mA => Level
0 – 1000 cm
