ORP OVERFEED

The ORP Overfeed timeout occurs when the CAT 4000 has been feeding chemical

for a time greater than the selected maximum feed time and has not reached its set

point. A properly selected Overfeed timeout prevents the unit from continuing to

feed chemicals when the chemical supply has been diminished or a chemical feeder

has become clogged or broken. First, check the chemical supply and chemical

feeder. If both are in order check the Overfeed timer setting as it may need to be

increased to keep up with chemical demand.

ORP TANK LOW

The ORP Tank Low alarm will sound when the chemical being fed falls below the

chemical level in the tank. First check the chemical level. If the level is above the

sensor, check the sensor for obstruction or calcification.

NO FLOW

The CAT 4000 is equipped with a flow sensor to prevent the controller from feeding

chemical in the absence of proper recirculation. First check the filtration system to

ensure that it is running and that water is moving through the flowcell. If water is

flowing and the alarm is still sounding check flow sensor for obstruction.

When using the optional Digital Flow Sensor, the digital flow alarm setting can be

entered in gallons-per-minute to send a No Flow alarm when the filters require

cleaning or backwashing.

SERVICE REQUEST

The Transmit button on the CAT 4000 sends logged data to the PoolComm web site

for immediate viewing and generates a service request alarm.

KEY INSERTED

When a service technician visits the CAT 4000 he may insert a service key (optional),

which will be logged by the controller to document the time and duration of his visit.
