IFT 3000 TROUBLESHOOTING

Consult Safety Data Sheet 1M03296

before performing any work on the

CENELEC approved IFT 3000.

Install all protective equipment covers

and safety ground leads after trouble-

shooting. Failure to install covers and

ground leads could result in serious

injury or death.

E-3 OVERVIEW

The IFT troubleshooting section describes how

to identify and isolate faults which may develop

in the IFT.

E-4 IFT TROUBLESHOOTING

IFT troubleshooting is achieved by determining

the functional status of the microprocessor

board and interpreting status displays on the

front panel.

a. Microprocessor Status LED

The microprocessor board includes an LED

to aid in isolating equipment faults. LED in-

dications are as follows:

1. LED OFF. IFT failure or power is re-

moved; refer to Troubleshooting Flow-

chart #1 (Figure E-3).

2. LED ON - STEADY. Heater system

failure; refer to Troubleshooting Flow-

chart #2 (Figure E-4).

3. LED ON - FLASHING.

Microprocessor normal.

b. Equipment Status (LCD) Displays

The status line of the GUI equipped IFT will

display one of the following conditions. To

troubleshoot an equipment fault, refer to

COMPONENT FAILURE indications appli-

cable to the display message (SYMPTOM)

in Table E-2.

1. OK - The system is operating normally.

2. CAL - The system is currently under-

going calibration.

3. C Err - An error was detected during

the calibration process.

4. H Err - There is a fault within the heater

system.

5. TGLow - There is no test gas pressure.

6. HiO

- The O

value is above the high

alarm limit.

7. LoO

- The O

value is below the low

alarm limit.

8. R Hi - The cell resistance is above the

high limit.

9. Off - The probe has been turned OFF

because the IFT cannot control the

heater temperature.

10. PRBE - The probe is disconnected,

cold, or leads are reversed.
