Gestra NRGS15-1 PN25
BRAND : Gestra
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 ?S/ 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 submer...

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
