Controller Storage
The controller unit is subject to damage by electro-static discharge (ESD) when the sensor cables
are disconnected. Always reinstall the BNC protective covers prior to storing or transporting the
HCC 1000 controller unit.
Winterization
The pH sensor should be prepared for storage as outlined above and protected from freezing tem-
peratures. Although the HCC 1000 controller is designed to withstand a broad temperature range,
winter storage in a secure location is desirable.
The flow cell and poly tubing must be drained prior to exposure to freezing temperatures. Either
purge all water using compressed air or thoroughly drain through the valve ports and tubing con-
nections.
Each HCC 1000 controller is manufactured to the highest quality standards and then thoroughly
tested before leaving the factory. State of the art design and fabrication technology ensure years of
trouble free operation. Most apparent malfunctions can be solved through the following corrective
actions:
No lights are illuminated when controller is powered on.
1.
Check circuit breaker and/or receptacle for proper operation. Connect to functional ground-
ing-type GFCI protected power source.
2.
Check for damaged power cord or connector.
Alarm light(s) and tone are observed.
1.
Ensure that filtration system is functioning properly, flow is adequate, and water chemistry is
in balance.
2.
Ensure that sensor and power cables are properly connected to their respective connectors on
the controller unit.
3.
Check chemical feeders for proper operation.
4.
Ensure that flow sensor is properly installed and connected.
pH chemical feeder is not activated as expected.
1.
Ensure that acid/base feed mode is properly set for your chemical feeding requirements.
2.
Make sure "auto" pH feed mode is selected.
3.
Check pH Setpoint.
pH requires frequent calibration.
1.
Clean the pH sensor as outlined in the maintenance section. If sensor continues to provide
unstable readings after cleaning, replace sensor.
pH readings are inconsistent or slow in response.
1.
Ensure that sensor cables are properly connected to their respective BNC connectors on the
controller unit.
