Fuse Replacement
To replace either fuse, disconnect AC power, disconnect the positive (+) battery terminal from the battery,
and carefully replace the blown fuse with the correctly sized replacement fuse. Reconnect the positive (+)
battery terminal to the battery, plug the male plug end of the AC power cord to the electrical outlet, and
verify that power and functional operation has been restored.

9.5 Temperature Sensors Disconnected
If the temperature Sensors become disconnected or damaged, the Display Indicator for that sensor will show
a line of bars (- - -). This problem should be corrected before any attempt to calibrate the sensor is made.
9.6 Temperature Sensors Out of Calibration
If the operator believes that the temperature sensors are not reading correctly, the following steps should be
followed: Obtain a thermometer that is known to be accurate. Place this thermometer next to the temperature
sensor for at least 10 minutes. Insure that there are no strong breezes or winds blowing on the thermometer
and the sensor being calibrated. Note the temperature from the thermometer and use this reading to calibrate
the sensor. Refer to Section 10.3 for Sensor Recommendations.
9.7 Trouble-Shooting the Auxiliaries
The auxiliary inputs must always form a closed loop circuit. If the loop is ever open, the alarm will sound. If
an auxiliary input is sounding, the trouble can be isolated between the alarm and the circuit by disconnecting
the circuit from the terminal block in the alarm box and replacing it with a jumper (See Section12.8). If the
corresponding auxiliary input still causes an alarm condition, the problem is in the PCB circuitry, otherwise
the wiring is the culprit.
