APPENDIX 2
SCOUT and SPS Error Codes and Corrective Actions
The Surface Interface may experience communication problems due to noisy
environments, grounding problems, or installation issues. The LCD on the SPS-1500
will display error codes depending on the failure it is detecting. Below is a list of
common error codes and possible solutions to assist with troubleshooting the SPS-
1500. To change the settings recommended you will need to use Sercel DataWorks
software.
Note: The Troubleshooting Steps represent individual actions in the sequence
they should be tried. If the first one doesn’t work try the next one.
Error
Possible Cause
Troubleshooting Step
DC-DC Bad or
DC-DC Chk -
(Voltage
measured by
SPS is not
matching what
is sourced by
SPS.)
 Bad Ground Connection
 Low Resistance from Gauge
Signal to Ground
 Excessive Gauge signal line
current
 Faulty SPS
 Check Downhole readings (Phase-Phase & Phase-
Ground (Reverse Polarity Megger))
 Try alternate SPS power supply
 Use voltmeter to confirm voltage MAX Voltage is
over 45VDC.
Baud Fast –
(Gauge Data is
changing at a
Rate higher
than expected)
 Set voltage is too high
 Motor noise affecting gauge
current modulation
 Disable Auto Baud and raise Max Tool Baud to 8-10
 Reboot or cycle power to restart analyzing stage
 Disable Auto Volt/ Auto Analyze with DataWorks. Set
voltage to ~60VDC.
Low Amps –
(Gauge current
is lower than
expected)
 Disconnected from tool
 High resistance connection at
motor WYE point to gauge
 Blown Signal fuse
 Low amp setting set to high
 Check Downhole readings (Phase-Phase & Phase-
Ground (Reverse Polarity Megger))
 Check all connection(s)
 Check Signal fuse
 Check Setting of Low amp with DataWorks (15VDC
Nominal)
 Check Setting of High amp with DataWorks (25VDC
Nominal)
High Amps –
(Gauge current
is higher than
expected)
 Poor Wellhead grounding
 Excessive Gauge Signal Line
Current or injection of noise
from motor at wye point.
 Connect to the SPS with “DataWorks” software to
manually set the following current settings for the
gauge:
 - Check Setting of Low amp (15mA normally for SPS-
1500 and 2-8mA normally for SPS-1501)
Note: During normal start-up communications with the tool you will see error
messages such as “High Amp”, “Low Amp”, “DC-DC Bad”, “DC-DC Chk”, “Analyze 1”
through “Analyze 16” as well as other normal messages that are all part of acquiring
the tool. After the SPS analyzes the line current from the tool you will see the
message “SPS Power OFF” a couple of times. Then the SPS will show 2 or 3 phase
Sync cycles and then begin to read gauge header data. This is all part of normal
operations of the SPS-1500. There is only a concern when an error message is
repeated multiple times and communications is not established with the gauge after
five minutes.
