●
Bad spectrometer detector or source
●
Check ‘Last Vmax’ and ‘Last Vmin’ in ‘Status’. Nominally Last
Vmax >4.0 Volts, Last Vmin <-1.0 Volts. Readings of <±0.5
Volts indicate detector or source failure. Marginal readings may
require more detailed analysis by Thermo Fisher Scientific
Technical Support Department.
●
Concentration not updating in IMACC
●
See ‘Communications Errors/No Communications with FTIR’.
●
H
2
O concentrations <2000 ppm during zero checks
●
Make sure hydrator is not filled with water.
System does not start automatically
●
Verify the following programs are in the setup:
Omni.layout
ImaccCurrentLoop
ImaccModbus
ImaccModbusTCP
●
See “ System Startup ” in Chapter 2.
Bad temperature readings – Either in ‘Status’ or in Modbus block in
IMACC script (See Appendix E, “ IMACC Script Setting ”.)
●
“Last Temperature” reading in ‘Status’ on ImaccMonitor software
main screen reads 185.000000.
●
Check virtual com port number (See Appendix D, “ Calogix
Setup ”).
●
Check USB connection between PC and temperature
controller.
●
Stop and re-start script in ImaccMonitor.
●
“Pump” sampling box temperature reading is low, but other
temperatures are OK.
●
Check thermostat inside pump box (See Chapter 5, “ Preventive
Maintenance and Servicing ”.
●
ERROR_QUANT_TEMPRESSCON in ImaccMonitor
●
Check temp control breaker and AC wiring connections.
