 - Check Setting of High amp (25mA normally for
SPS-1500 and 22-26mA normally for SPS-1501)
 Verify Downhole readings (Phase to Phase, Phase-
Ground (Reverse Polarity Megger))
 Replace the SPS-1500/SPS-1501
Analyzing –
(SPS is
adjusting
output voltage
to analyze
gauge signal)
 Normal Operation message
unless message is continuous
or repeating over 5 minutes.
 If message is continuous or repeats over 5 minutes:
o Check all wire connections
o Check Phase to Phase and Phase-Ground
connection (Reverse Polarity Megger) (Applies to
SPS-1500 only)
o Check Signal fuse
o Adjust Set voltage (Approx. 60+/- for 1500 and
Approx. 40+/- for the SPS-1501). This can be
done using “DataWorks” software.
No Tool – (No
Tool indicates
there is no
gauge current)
 Blown SPS Fuse
 Blown Surge Protector
Fuse/MOV
 Bad SPS to Gauge Signal wire
connection
 No-Tool Current setting
incorrect in SPS
 Read the DC current drawn by the gauge with an
ammeter in series and DC mode. DC current is
normally 15-30mA.
 Check all fuses and surface connections.
 If connections and equipment okay error may
indicate possible downhole connection is open.
 Using “DataWorks”, verify “No Tool Amp” value is set
to 5.3mA (default value).
Line Noisy –
(SPS is unable
to measure
current
modulation
from gauge)
 Motor WYE phase imbalance
voltage is high
 Check all fuses and surface connections.
 If connections and equipment okay error may
indicate possible downhole problem.
 Check line voltage at wye point on surge protector for
motor noise injection.
No Signal –
(SPS
measures
gauge current
but no
modulation
current)
 Possible SPS/gauge firmware
corruption
 Possible SPS/gauge
component failure
 No-Tool Current setting
incorrect in SPS
 Use DC Ammeter to measure DC current from SPS
to gauge. Gauge current is normally modulated from
approximately 15mA to 25mA. If not modulated,
check SPS and connections.
OKAY
 Normal Operation, no errors
 SPS is communicating with the gauge
Table 2: Surface Interface Troubleshooting
Note: Many communication problems with the Surface Interface can be solved with
proper grounding techniques. A good ground must be established from the
production tubing at wellhead back to the ground point at the surface package for
proper operation.
