The instrument offers
two modes
for purge operations (water drain) of the SV.
-
TIMER mode:
for easy programming or in case of conductivity probe fault, the operator may enable the Timer mode; the SV is driven by the
internal timer regardless of the conductivity reading in the operating Cooling tower.
-
CONDUCTIVITY mode:
processes the conductivity level to control purge operations; the displays show the measured EC values and drive
the relay output connected to the SV solenoid valve. Electroconductivity is monitored by a setpoint: once this is reached, the instrument
commands solenoid valve opening and drains the desalinated and conditioned water.
The first step requires enabling the drain SV (solenoid valve):
