Trident Water Management System
Trident Operation
When the Networker is turned ON, and the cooler is required to start from an empty
tank, the pump is delayed until the tank has sufficient water for it to operate.
As the tank fills, the water eventually makes contact between the Common Water
Sensor probe and the Low Water Level Sensor probe, at which point the pump can
start operation (Pre Wet).
When the tank fills to the high water level, The N-E5 switches OFF the water inlet
solenoid.
During the course of normal operation, with the water inlet solenoid closed, the tank
water level is evaporated down to the low water level.
The water contact between the Common Water Sensor and the Low Water Level
Sensor probes becomes open circuit.
The N-E5 will then switch on the water inlet solenoid again to refill the tank to the high
water level.
The N-E5 module is programmed as part of the overall control, if the expected water
levels are not achieved within designated times, then the N-E5 will go to water level
limp
mode operation.
As the water level control probes will be constantly subjected to water and electrical
power during normal operation, it is expected that a coating will eventuate, depending
on the water quality.
