SECTION 5
TROUBLESHOOTING
5-1 OVERVIEW
This section describes the SPS 4000 trouble-
shooting procedures. Additional troubleshooting
information can be found in the Oxymitter 4000
Oxygen Transmitter Instruction Bulletin.
Install all protective equipment covers
and safety ground leads after trouble-
shooting. Failure to replace covers
and ground leads could result in seri-
ous injury or death.

SPS 4000 TROUBLESHOOTING
Use the CAL FAIL and IN CAL relay outputs to
identify possible SPS faults.
a.
If a calibration was not successfully com-
pleted, the SPS 4000 sends a CAL FAIL
contact indication to the control room. To
determine if the SPS 4000 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 Instruc-
tion Bulletin.
1. If no alarms are indicated on the key-
pad or in the HART/AMS STATUS sub-
menu, the calibration did not fail be-
cause of an Oxymitter 4000 fault.
Therefore, a calibration gas flow prob-
lem occurred. Refer to Table 5-1 or
Figure 5-1 to troubleshoot the SPS
4000.
2. If the LAST CAL FAILED alarm is indi-
cated on the keypad or in the HART/
AMS STATUS sub-menu, the failure is
due to either a bad Oxymitter 4000 cell
or a calibration gas flow problem.
(a) Verify your calibration setup per
paragraph 2-3 in Section 2, IN-
STAL-LATION; Section 3, OP-
ERATION; and paragraph 4-8 in
Section 4, MAINTENANCE AND
SERVICE.
(b) Perform another calibration and
monitor the process. If the calibra-
tion 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 4000.
If the calibration setup is correct
and the Oxymitter 4000 indicates
an invalid slope fault (fault 12) be-
fore 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 Transmit-
ter Instruction Bulletin.
b.
If a semi-automatic or manual calibration is
being performed but no 5 - 30 VDC relay
output contact (IN CAL or CAL FAIL) is be-
ing received by the control room, the inter-
face board relays are malfunctioning.
Replace the interface board per paragraph
4-3 in Section 4, MAINTENANCE AND
SERVICE.
NOTE
If the unit is performing frequent auto-
calibrations, investigate at the Oxymit-
ter 4000 site or using HART/AMS. This
condition may indicate an aging cell in
the Oxymitter 4000.
