●
Check for 24 VDC signal on temperature alarm connections to
probe off of the electrical panel using a multimeter. If only one
connection has 24 VDC, check temperatures at probe.
●
System in failsafe mode – zero air
●
Check alarm system continuity at sample probe, umbilical
wiring and temperature control box. See Chapter 7, “
System
Component Description ” and Appendix D, “ Calogix Setup ”.
●
Check Calogix software for correct software setup for alarm
states; see Appendix D, “
Calogix Setup ”.
●
“Last Pressure” reading in ‘Status’ on ImaccMonitor software main
screen reads 750.000000.
●
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.
External communications errors
●
Ethernet not communicating
●
Check IMACC Modbus TCP server running on PC.
●
Check power LED on ADAM hub Chapter 7, “ System
Component Description ”. If off, check 24 VDC breaker and
wiring to and from power supply.
●
Check Ethernet cable between computer and ADAM hub; see
Chapter 7, “
System Component Description ”.
●
Serial
●
Check IMACC Modbus TCP server running on PC.
●
Check serial cable connection.
●
Check ‘Hardware’ setup in Windows system menu.
Internal communications errors
●
No temperature readings or heating of system components
●
See ‘Temperature errors’ in this chapter.
●
No communications with FTIR
