IFT 3000 TROUBLESHOOTING

E-3 OVERVIEW

The IFT troubleshooting section describes how to identify and isolate faults which may develop in the IFT.

Install all protective equipment covers and safety ground leads after trouble- shooting. Failure to replace covers and ground leads could result in seri- ous injury or death.

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 system status display (one at a

time) in priority sequence, as indicated in the following list. To troubleshoot an equip- ment fault, refer to COMPONENT FAILURE indications applicable to the display mes- sage (SYMPTOM) in Table E-2.

1.Off - The probe has been turned off because the IFT cannot control the heater temperature.

2.Param - IFT has been unlocked using the user’s password.

3.Serv - IFT has been unlocked using the service password.

4.PrbEr - The probe is disconnected, cold, or leads are reversed.

5.HtrEr - If HtrEr is displayed, there is a fault within the heater system.

6.InCal - If InCal is displayed, the system is currently undergoing calibration.

7.LowO2 - If LowO2 is displayed, the O2 value is below the low alarm limit.

8.HiO2 - If HiO2 is displayed, the O2 value is above the high alarm limit.

9.NoGas - If NoGas is displayed, there is no calibration gas pressure.

10.CalEr - If CalEr is displayed, an error was detected during the calibration process.

11.ResHi - If ResHi is displayed, the cell resistance is above the high limit.

12.OK - If OK is displayed, the system is operating normally.
