L.E.D. Status Codes
L.E.D. Status Codes
•
L.E.D. on steady
: Indicates normal operation.
•
Steady one second flashing:
Indicates dirty probes, reading in the capacitance
mode. The unit will still operate but will give the following status code of 1 second
on, 1 second off (steady 1 second flashing). This status code will continue until the
probes are cleaned and the power has been reset. Note: No other status codes will be
displayed until the dirty probes are cleaned.
•
Two flashes and off for 5 seconds
: Indicates make-up valve ran for more than 1 hour.
The unit will continue to fill, with the following status code of 1 second on, 1 second
off, 1 second on and then off for 5 seconds before repeating. This status will continue
until power has been reset.
Possible causes
: leaking tank, obstructed fill / defective
valve or reduced flow rate.
•
Three flashes and off for 5 seconds
: Indicates shorted probes or high conductive
water. The unit will continue to operate but will give the following status code of 1
second on, 1 second off, 1 second on, 1 second off, 1 second on and then off for 5
seconds before repeating. This status will continue until the water is diluted or the
short is removed from the probes and power is reset.
•
Four flashes and off for 5 seconds
: Indicates black probe (P6) reads covered, but
White probe (P5) does not read covered (White should also be covered because it is
longer than the Black). This will cause the fill solenoid valve to short cycle and lead
to premature failure of the fill valve. The unit will short cycle and give the status code
of 1 second on, 1 second off, 1 second on, 1 second off, 1 second on, 1 second off,
1 second on and then off for 5 seconds before repeating. The unit will continue short
cycle until the condition has been corrected (clean white probe) and reset the power.
•
L.E.D. does not come on after power up or resetting power
: Indicates unit inoperative.
