Error Recovery Procedures
General Error Recovery
When a problem occurs at a unit, an audible alarm sounds and flashing warning lights activate. The
keypad display at the affected unit will show which error code the problem generated. The error
code is a three-digit number, which the keypad display shows in two segments (for example, "1-50").
The error code and sensor in question will also be displayed in red on the bottom left hand corner
of the Line Controller until the alarm is silenced. The unit generating the error code will also be
highlighted in red on the Line Controller until error is cleared.
1 Press the ALARM button on the keypad of the affected unit to silence the alarm.
2 Read the first one-digit segment of the error code on the keypad display on the affected unit.
3 Press the FUNCTION (-) button on the keypad to view the second two-digit segment of the error
code on the keypad display. The combination of the first one-digit segment and second two-
digit segment gives the complete three-digit error code used for troubleshooting the problem.
4 Refer to the Error Code tables for the appropriate Unit Error Code. For example, if the error
occurs at the Outlet Unit, refer to Table2.1,Outlet Unit Error Codes.
5 Look up the error code in the Keypad Display column of the error code table.
6 Read the information in the Sensor, Problem, and Solution columns for that error code. Do not
yet attempt to perform the steps suggested in the
Solution column.
7 Locate the sensor on the appropriate Unit Sensor Diagram by using the Grid Ref (Grid
Reference). On the edges of the sensor diagram highlighted in Yellow is the locating reference
grid. Follow the appropriate letter and number to the intersecting area on the sensor diagram.
The sensor in error is located in the intersecting area.
