Operation, alarm and test
Setting banking-up of condensate, mode 2 to 7
The precondition for this operating mode is:

the use of the measuring electrodes NRG 16-27, NRG 16-28 (with integrated condensate temperature
measurement at the steam trap).
With the parameter dtC the factory set difference of 40 K (admissible condensate undercooling) between
the temperature measured at the steam trap and the switchpoint “Banking-up of condensate” can be
changed. The value can be changed in increments of 1 K and must be between 0 and 100 K.
In the parameter
CAL the condensate temperature of all steam traps is polled, the difference dtC is
subtracted and the result saved.
Starting from the parameter
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.
The parameter
tlo
allows you to set the lower temperature limit within a range of 0 to 100 °C in
increments of 5 K. If the condensate temperature is below the temperature limit, the alarms "Banking-up
of condensate" and "Steam loss" will neither be indicated nor stored.
