Sensor Read Test Codes: Notes
- The sensor read test checks each circuit for proper operation. If correct code does not appear on display during test, circuit and components must be checked. Place system in Diagnostic Test Mode and wait for Code 55 to appear on display.
- Press ATM button to activate display. If a specific sensor read test is desired, hold ATM button down until desired code is displayed. Slide read/hold switch to "HOLD" position to display corresponding sensor output level.
NOTE:
Since the sensor access codes are the same as some ATM test codes, the ATM test circuit will turn on before moving the read/hold button to "HOLD" position.
