F-6 95-8526 14.2
DiAGnostics/service MenU
The specific diagnostic and/or service functions available are:
1 test Device
1 Self-test. Internal tests are performed and any problems are reported in
xmtr flt 1 and xmtr flt 2.
2 Response Test. The analog output is held at 4 mA to prevent the alarm relays
from activating when gas is applied. Gas response is indicated
by the PV.
3 Reset. Latched relay outputs are reset.
2 loop test
This test allows the operator to manually set the analog signal output to a selected constant
value.
3 calibration
This menu option initiates the calibration routine and is used to set device calibration preferences.
Calibration Submenus include:
1 Zero Trim. The current sensor input is used as the new zero reference.
2 Calibrate Sensor. This is the command used to calibrate the Eclipse Detector. Submenus include:
1 Calibrate. Zero and span calibrations are performed.
2 Cal Concentration. The output will be set to this value when gas is applied during calibration.
3 Cal Gas
4 Gas Type. Submenu includes optional gases:
– Methane
– Propane
5 Calibration Type. Submenu includes options:
– Standard
– Cuvette
6 Cuvette Length (in millimeters)
3 Calibration Date (CalDate). Shows date of last calibration
4 D/A trim (internal use only).
4 status
This menu option shows extensive status information about the detector. Data available includes:
1 Reference xxxx (output value of the reference sensor).
2 Snsr temp xxxx (temperature of the sensor that is making the process measurement).
3 Operating mode (calibration, normal, reset)
4 Calibration
5 xmtr flt 1. Xmtr flt and xmtr status provide status information relating to failures, warnings and status
of processes.
6 xmtr flt 2
7 xmtr status 1
8 xmtr status 2
