Error Messages
"Current min"
The minimum permitted current of the respective unit is undercut for
longer than 5 seconds following switching OFF of the unit. The
value of the current, which is measured, is saved as environmental
condition.
"Current max"
The maximum permitted current of the respective unit is exceeded
for longer than 5 seconds following switching ON of the Unit. The
value of the current, which is measured, is saved as environmental
condition.
"Flooding"
A flooding alarm is identified as, despite the maximum, activation
time of the clarified water pump, no change of the float has been
identified.
"Float supply"
For the measurement of the float level, the float is supplied with a
separate voltage, which is used for diagnosis. An error “Float
supply” leads to the generation of a default value “Float up”, i.e. the
processes run in normal mode with cyclical flooding alarm as
pseudo error.
UVS
®
(Under Voltage Signalling / Voltage failure detection)
The UVS
®
simplifies the safeguarding of an efficient operation. If there is a power failure (supply
voltage < 100 V), e.g. through the activation of the residual current circuit breaker (RCCB) or a
fuse, an acoustic alarm is initiated. The pulse tone continues, depending on the charged status of
the accumulator, for up to 24 hrs. The signal is deactivated by pressing any key or as soon as a
sufficiently high voltage is generated. Adjustments do not have to be undertaken. A power failure is
recorded in the logbook.
