Description
The NRGS 15-1 is a compact-type system consisting of a
level electrode with four tips and an integrated level switching controller. The compact system is used as water level
controller / limiter, for instance in steam boilers, (pressurized)
hot-water installations as well as condensate and feedwater
collecting tanks. Function
The level switch NRGS 15-1 is a compact-type system consisting of a level electrode with four tips and an integrated
level switching controller. The equipment works only with
water having a min. electrical conductivity of > 0.5 μS/
cm at 25 °C. In the integrated level switch a time-delayed
switching channel, an output relay and a signal LED are assigned to each one of the four electrode tips. The functions
of the switching channels 1 and 4 are fixed, the switchting
channels 2 and 3 can be adjusted via code switch to suit
individual requirements. The tips of the electrode are cut to
length on site in order to establish the desired switchpoints
of the associated switching channels. The following functions
are possible:
n Electrode rod 1 exposed / switching channel 1 energizes
relay 1 = low level 1 with optional performance test and
lock-out function
n Electrode rod 2 exposed / switching channel 2 energizes
relay 2 = low level 2
n Electrode rod 3 exposed or submerged / switching channel
3 energizes relay 3 =timed pump control (fill/discharge
control)
n Electrode rods 2 and 3 exposed or submerged / switching
channel 3 energizes relay 3 = on/off pump control (fill/
discharge control)
n Electrode rod 4 submerged / switching channel 4 energizes relay 4 = high level
