5.0 Error messages, possible faults and remedy
5.1 Error messages in the display
Message in the display Possible cause Remedy
Thermal fault 1 The control contact of the pump in question
has tripped If the pump in use does not have the relevant
thermal motor protection switch, the function
must be disabled in the menu (see section 4.2.
above, section on Thermal fault 1, thermal fault
2).
Check pump, remove foreign body as required
if blocked. Check that the motor has cooled
sufficiently.
Thermal fault 2
The limiter contact of the pump in question
has tripped If the pump in use does not have the relevant
thermal motor protection switch, a jumper must
be used for each pump used (see section 6.3.
below, section on Thermal motor protection
switches).
Check pump, remove foreign body as required
if blocked. Check that the motor has cooled
sufficiently (dry running).
Once the pump has cooled down, press the
Acknowledge button to enable the pump.
No load Phase 2 is missing or the control system is
operated with no load. Check mains supply, pump cable and pump
Overcurrent The motor current is higher than the value
set in the current monitoring Check pump for functionality and check current
monitoring setting
Overflow alarm The level has exceeded the overflow level Check pump for functionality and check
overflow level setting
Overflow float switch Contact for overflow float switch has closed Check pump and float switch for functionality
Switching point below
tripping point The settings for the switching point and
tripping point overlap Check the level settings
Overflow below the
switching point The settings for the overflow alarm and
switching point overlap Check the level settings
Runtime fault Pump runs uninterrupted for longer than the
set period Check pump for functionality
Float switch malfunction
Plausibility check of the float switches;
sequence incorrect Check float switches for functionality and
electrical connection
Protection against dry
running
activated Contact for protection against dry running
has opened Check pump and float switch for functionality
Interface <3 mA Signal for the external level probe lower
than 3 mA Check level probe, explosion barrier and
electrical connections
Check the switch points
The measuring range of the external level
probe has changed. Switch points are
outside of the measuring range Check the level settings
Rotating field fault One or two phases are missing, or rotating
field is incorrect Check whether all 3 phases and if the rotating
field is correct
ATEX: Level below
tripping point The ATEX mode is activated, and the level
is below the tripping point of the selected
pump In areas with a potentially explosive
atmosphere, the level must rise above the
tripping point for the pumps before they can be
activated.
If the pumps are not located in areas with a
potentially explosive atmosphere, the ATEX
mode can be disabled in the menu.
