Instruction Manual
IM-106-340AC-1, Rev. 1.0
April 2005
SPS 4001B
5-2
1. Verify your calibration setup per "Gas Connections" in Section 2,
Installation; Section 3, Operation; and "Flow Meter Adjustments" in
Section 4, Maintenance and Service.
2. Perform another calibration and monitor the process. If the calibration
fails before both calibration gases finish sequencing, a gas flow problem
exists. Refer to Table 5-1 or Figure 5-1 to troubleshoot the SPS 4001B.
If the calibration setup is correct and the Oxymitter 4000 indicates an
invalid slope fault (fault 12) before the gases are purged and a last
calibration failed fault (fault 14) after the gases are purged, replace the
Oxymitter 4000 cell per the Oxymitter 4000 Oxygen Transmitter
Instruction Manual.
Relay Failure
If a semi-automatic or manual calibration is being performed but no 5 - 30
VDC relay output contact (IN CAL or CAL FAIL) is being received by the
control room, the circuit board relays are malfunctioning. Replace the circuit
board per "Circuit Board Replacement" in Section 4, Maintenance and
Service.
NOTE
If the unit is performing frequent auto-calibrations, investigate at the Oxymitter
4000 site or using HART/AMS. This condition may indicate an aging cell in the
Oxymitter 4000.
