Replacing the Fuse Protecting Powered Relays

CAUTION: Disconnect power to the controller before opening front panel!

Locate the fuse on the circuit board at the back of the controller enclosure under the plastic safety cover. Gently

remove the old fuse from its retaining clip and discard. Press the new fuse into the clip, secure the front panel of

the controller and return power to the unit.

Warning: Use of non-approved fuses can affect product safety approvals. Specifications are shown below. To

insure product safety certifications are maintained, it is recommended that a

Pulse

fuse be used.

7.3 Replacing the System Fuse (For model codes with relay option 8 or 9 only)

CAUTION: Disconnect power to the controller before opening front panel!

Locate the system fuse on the lower right-hand corner of the circuit board at the back of the controller enclosure

under the plastic safety cover. Gently remove the old fuse from its retaining clip and discard. Press the new fuse

into the clip, secure the front panel of the controller and return power to the unit.

Warning: Use of non-approved fuses can affect product safety approvals. Specifications are shown below. To

sure product safety certifications are maintained, it is recommended that a

Pulse

fuse be used.

8.0 TROUBLESHOOTING

CAUTION: Disconnect power to the controller before opening front panel!

Troubleshooting and repair of a malfunctioning controller should only be attempted by qualified personnel using

caution to ensure safety and limit unnecessary further damage. Contact the factory.

8.1 Calibration Failure

Calibrations will fail if the adjustments to the reading are outside of the normal range for a properly functioning sys-

tem. Refer to the instruction manual for the specific sensor being used for further information.

8.1.1 Contacting Conductivity Sensors

The calibration will fail if the adjustment to the gain is outside of 0.5 to 2.0.

Possible Cause

Corrective Action

Dirty electrode

Clean electrode

Improper wiring of sensor to controller

Correct wiring

Wrong cell constant entered

Program the controller cell constant setting at the value that

matches the electrode being used

Incorrect temperature reading or setting

Ensure that the temperature is accurate
