Trident Water Management System
(cont.)
Abnormal Operation
Water Limp Modes
The Trident water management system will automatically adopt a controlled
operation, if it detects the malfunction of the sensing probes, or detects water in the
tank when it's not expected.
There are 4 water management errors modes, and these operation modes are
communicated to the Networker to indicate the malfunction.
Low Water Level Sensor (failure) - Error 40
High Water Level Sensor (failure) - Error 41
Drain (operation failure) - Error 42
Water Sense Failure (both low and high level sensors)
-
Error 50
Water Limp mode errors 40, 41 and 42,
do not require the cooler to be shut down
,
but the coolers filling and flush operation is time controlled.
These errors (where available) will only be
displayed during
the time the
water inlet
solenoid is open
and will alternate between the error screen and the normal display.
The N-E5 module will
delay, for 4 minutes
, any Limp mode error display at the
Networker, just in case the error rectifies itself.
Should the Limp mode condition correct itself, then normal operation and function
times will be restored.
Error 50
is different and will cause a
lockout
, but provides the user the facility to
reset the operation at the Networker. However, if the condition is still present after
reset, the unit will lockout again.
