This section describes the SPS 4001B troubleshooting procedures. Additional
troubleshooting information can be found in the Oxymitter 4000 Oxygen
Transmitter Instruction Manual.
Secure equipment cover and ground leads after troubleshooting. Failure to secure covers
and ground leads could result in serious injury or death.
Use the CAL FAIL and IN CAL relay outputs to identify possible SPS faults.
CAL FAIL
If a calibration was not successfully completed, the SPS 4001B sends a CAL
FAIL contact indication to the control room. To determine if the SPS 4001B
caused the failed calibration, go to the Oxymitter 4000 site to view the keypad.
Or, access the HART/AMS menus. For more information on HART/AMS, refer
to the HART/AMS section in the Oxymitter 4000 Oxygen Transmitter
Instruction Manual.
If no alarms are indicated on the keypad, LOI, or in the HART/AMS STATUS
submenu, the calibration did not fail because of an Oxymitter 4000 fault.
Therefore, a calibration gas flow problem occurred. Refer to Table 5-1 or
Figure 5-1 to troubleshoot the SPS 4001B.
If the LAST CAL FAILED alarm is indicated on the keypad, LOI, or in the
HART/AMS STATUS submenu, the failure is due to either a bad Oxymitter
4000 cell or a calibration gas flow problem.
