Figure 8-4. Fault 2, Shorted Thermocouple

b. Fault 2, Shorted Thermocouple

Figure 8-4 shows the electronic assembly

for a Hazardous Area Oxymitter 4000 with

a membrane keypad (upper view) and a

Hazardous Area Oxymitter 4000 with an

LOI (lower view). The upper view also

shows J1 and test points TP1 through TP6,

located on the microprocessor board, below

the membrane keypad or the LOI module.

Membrane Keypad. When Fault 2 is

detected, the HEATER T/C LED flashes

twice, pauses for three seconds, and

repeats.

1. Us ing a multimeter, measure the volt-

age from TP3+ to TP4-. If the reading

is 0 ±0.5 mV, then a shorted thermo-

couple is likely.

2. Rem ove power and disconnect J1.

3. Meas ure the resistance from TP3+

to TP4-. The reading should be ap-

proximately 20K ohms.

4. If so, the short is not on the PC board.

The thermocouple wiring or the ther-

mocouple is shorted. See paragraph

9-4g, Heater Strut Replacement.

LOI. When Fault 2 is detected, the LOI

displays the “O2 T/C Shorted” message.

1. Rem ove power. Unscrew and remove

the LOI module from the electronic

assembly.

2. Rec onnect power to the Oxymitter

4000.

3. Perf orm the diagnostic steps 1 through

4 shown for the membrane keypad.
