Function as timer

The TIMER function can be assigned to each of the 4 relays.
As a timer the relay works completely independent of the measured value and continues working
during the calibration procedure when the measured value and other relay functions are frozen
(see also chapter "Calibration").
This operation mode can e. g. be used as "hand control" with self-defined times.
The times T 1 and T 2 are input in the parameterization level under "PARA TIMER".
Illustration of the timer function:

Function as limit contact

If a relay is configured as a limit contact with UL / LL, free assignment to a parameter is possible.
The relay can be assigned to the following parameters:
Parameter
UL LF
LL LF
UL TEMP
LL TEMP
Parameters which have already been assigned are no longer offered in the menu during the
configuration of the next relay.
90
The time T 1
The time T 2
During T 1 the relay is inactive,
during T 2 it is active.
Explanation
UL = upper limit value
LL = lower limit value
LF = Conductivity value
TEMP = Temperature
Configuration
