SPS 4001B TROUBLESHOOTING
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
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.
