14.1.4 Diagnosis parameter list
For each item, specify whether it is to be checked or tested. Test items are marked “Yes”.
Items which are ignored are marked “No”. Each item is marked either “Yes” or “No”. For
example, if the septum counter is marked “Yes”, both the INJ1 and INJ2 will be chacked.
COUNTER FOR SEPTUM
COUNTER FOR INSERT
Verifies whether the preset number of injections has been exceeded.
The “ANALYSIS COUNTER” limit is displayed.
CRG USE TIME
Verifies whether the valve “On” time exceeds the preset operating time.
The “COOLANT CONSUMPTION” limit is displayed.
TEMP SENSOR USE TIME
The operating time for the temperature sensor in use at 300 °C or above is displayed. Refer
to the guidelines for operating time.
TEMP SENSOR DIAG
Verifies whether spiking noise has been generated, to detect deterioration of the platinum
sensor.
LCD USE TIME
Verifies whether the accumulated backlight ON time exceeds the preset operating time.
The limit 15,000 hours.
FAN USE TIME
Verifies whether the accumulated fan operating time exceeds the preset operating time.
The limit is 43,800 hours.
DC VOLTAGE (5 VDC, 24 VDC, -15 VDC, FTD 24 VDC)
Verifies whether each DC voltage has exeeded its limit.
ROOM TEMPERATURE
Verifies whether the current room temperature is within the optimal range.
The range is 5 to 40 °C.
ATMOSPHERIC PRESS
Verifies whether the atmospheric pressure is within the optimal range.
PRIMARY PRESS
Verifies whether the gas supply pressure is within the maximum set pressure.
CPU REGISTER
REAL TIME CLOCK REGISTER
Verifies that each register is correctly written and read.
DETECTOR ROM
Verifies that the data saved in the detector ROM is read correctly.
DETECTOR ADC REGISTER
Verifies that the data saved in the detector A/D converter register is read correctly.
DETECTOR HV SOURCE
Verifies whether the detector high voltage power supply is within the threshold.
CAUTION
At the time of Diagnosis, set the Split mode to “SPLIT”. When WBI
column is used, set the split mode to “DIRECT”.
