PROBLEM WHAT THIS MEANS CORRECTIVE ACTION
“SENSOR READS
ZERO”
You are trying to perform a span calibration of the
conductivity and the conductivity sensor reads
zero.
1.
Check wiring.
2. Ensure sensor is full immersed in water.
3. The model 3323 for cooling towers will
not accept a span calibration below
about 200 µS. Cycle conductivity
higher and re-calibrate.
{ALARM FLASHING}
“COND:Fouled SENSOR”
Conductivity sensor is not reading properly.
1.
Clean sensor.
2.
Check wiring. Verify that all
connectors are fully mated.
3.
Replace conductivity sensor.
{Alarm Flashing}
“ORP: HIGH ALARM”.
ORP is too high with respect to the high
alarm setpoint.
1.
See {RLY: TIME EXCEEDED}.
2. Check the High Alarm Value.
3. Check relay setpoints and deadbands.
4. Check chemical drum levels.
5.
Check proper operation of chemical
pumps.
{Alarm Flashing}
“ORP: LOW ALARM”.
ORP is too low with respect to the low alarm
setpoint.
1. See {RLY: TIME EXCEEDED}.
2. Check the Low Alarm Value.
3. Check relay setpoints and deadbands.
4. Check chemical drum levels.
Water meters not
accumulating.
There may be a problem with the wiring or the
reed switch in the meter may be bad.
For water meters other than the contacting head
type, check the manufacturer’s user manual for
that particular water meter.
1. Approximately 24 volts DC should be
present at the input terminal when the
water meter contact is closed. That
should change to zero VDC when the
contact opens. Check these voltages and
for correct wiring.
2. Is the controller configured for your type
of water meter?
