SENSOR INPUT VOLTAGE HIGH INP1
NOTE
This alarm is an indication that there is a short in the DC current transformer wiring from another (nom-
inal 12 VDC) circuit into the transducer or CT sensor circuit.
• ACTIVATION: Voltage from main microprocessor to the sensors is greater than 5.5 VDC
• UNIT CONTROL: Alarm only.
• RESET CONDITION: Auto reset when sensor voltage is correct, alarm reset or alarm may be manually reset
by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, clear the
alarm(s). (Refer to Note 1 in
Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check Transducer Wiring
Check wires to sensors for short.
For CSP, check wiring from 2MM
−
20, 2MM
−
30 and 2MM
−
9.
For EVOP, check wiring from 2MM
−
28, SP
−
7 and 2MM
−
17.
For CDP, check wiring from 2MM
−
21, SP
−
7 and 2MM
−
10.
2.
Check CT Wiring
Check wires to sensor for short from another circuit. Check wiring from 2MM
−
29, 2MM
−
12 and 2MM
−

NO COMM FROM MICRO TO OUTPBD1
• ACTIVATION: Main microprocessor cannot communicate internally.
• UNIT CONTROL: Shutdown all modules except the display and alarm. (The alarm will only display if the dis-
play module is communicating.) Main microprocessor status LED will illuminate steady green (not pulsing).
• RESET CONDITION: Auto reset when internal communication is restored, alarm reset or alarm may be
manually reset by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, clear the
alarm(s). (Refer to Note 1 in
Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
