Setting banking-up of condensate, mode 2 and 7
The precondition for this operating mode is:
n
the use of the measuring electrodes NRG 6-7, NRG 6-8 (with integrated condensate
temperature measurement at the steam trap)
With the parameter dtC the factory set difference of 40 K between the temperature measured at the
steam trap and the switchpoint “Banking-up of condensate”. The value can be changed in increments
of K up to a max. limit of 00 K.
In the parameter mode
CAL the condensate temperature from all steam traps is polled, the difference
dtC is subtracted and the result saved.
Starting from the parameter mode
ALL, the switchpoint “banking-up of condensate” can be adjusted in
increments of 5 K for each individual steam trap (C.xx) in order to match the settings optimally to the
operating conditions.
