the following current settings for the gauge:
- Check Setting of Low amp (15mA normally for SPS-1500 and 2-
8mA normally for SPS-1501)
- Check Setting of High amp (25mA normally for SPS-1500)
•Verify Downhole readings (Phase to Phase, Phase-Ground
(Reverse Polarity Megger))

Troubleshooting Step
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:
- Check all wire connections
- Check Phase to Phase and Phase-Ground connection (Reverse
Polarity Megger) (Applies to SPS-1500 only)
- Check Signal fuse
- Adjust Set voltage (Approx. 60+/- for 1500 and Approx. 40+/- for
the SPS-1501). This can be done using “DataWorks” software.
Analyzing–
(SPS se está ajustando el
voltaje de salida para
analizar la señal del
sensor)
•
Mensaje de funcionamiento normal
a menos que el mensaje sea
continuo o se repita durante 5
minutos.
Si el mensaje es continuo o se repite durante 5 minutos:
•Verifique todas las conexiones de los cables
•Compruebe la conexión de fase a fase y de fase a tierra
(megóhmetro con polaridad inversa) (solo se aplica al SPS-1500)
•Comprobar fusible de señal
•Ajuste el voltaje establecido (Aprox. 60 +/- para 1500 y Aprox.
40 +/- para el SPS-1501). Esto se puede hacer usando el
software "DataWorks".

Troubleshooting Step
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).
No Tool –
Indica que no hay sensor
conectado
•Fusible SPS abierto
•Fusible / MOV del protector de
sobretensión abierto
•Mala conexión del cable de SPS a
la señal del sensor
•Configuración de corriente No-
Tool Current incorrecta en SPS
•Lea la corriente DC consumida por el sensor con un
amperímetro en serie y modo DC. La corriente DC debe ser
normalmente de 15 a 30 mA.
•Compruebe todos los fusibles y las conexiones de superficie.
•Si las conexiones y el equipo están bien, el error puede indicar
que una posible desconexión en el fondo.
•Usando “DataWorks”, verifique que el valor de “No Tool Amp”
esté establecido en 5.3mA (valor predeterminado).

Error
Possible Cause
Troubleshooting Step
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.
Line Noisy–
(SPS no puede medir la
modulación actual del
sensor)
•El voltaje de desequilibrio de fase
en el WYE point del motor es alto
•Compruebe todos los fusibles y las conexiones de superficie.
•Si las conexiones y el equipo están bien, el error puede indicar
un posible problema en el fondo del pozo.
•Verifique el voltaje de línea en el punto estrella del protector
contra sobretensiones (surge protector) para detectar la
inyección de ruido del motor.

Error
Possible Cause
Troubleshooting Step
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.
No Signal–
(SPS mide la corriente del
sensor pero no la corriente
de modulación)
•Posible corrupción del firmware
del sensor / SPS
•Posible falla en algún
componente del sensor / SPS
•Configuración de No-Tool
Current incorrecta en SPS
•Utilice un amperímetro de DC para medir la corriente DC de SPS
al sensor. La corriente del sensor normalmente se modula
desde aproximadamente 15 mA a 25 mA. Si no está modulado,
verifique SPS y conexiones.

LINE BAD–•Phase imbalance, short circuit or
damaged equipment
•Check drive, grounding to wellhead, surface cable to wellhead
and system grounds. Check Surge Suppressor MOV, fuses,
surface choke and wiring. Check gauge fuse on SPS-1500. Test
resistance/insulation of the downhole cable at wellhead
LINE BAD–•Desequilibrio de fase,
cortocircuito o equipo dañado
•Verifique el VSD, la conexión a tierra al cabezal del pozo, el
cable de superficie al cabezal del pozo y las tierras del sistema.
•Compruebe el MOV del supresor de sobretensión, los fusibles,
el choke de superficie y el cableado. Verifique el fusible del
sensor en el SPS-1500. Pruebe la resistencia / aislamiento del
cable de fondo de pozo desde la boca del pozo
•Reemplace SPS-1500

Error
Possible Cause
Troubleshooting Step
Packet Size–•Communication problem as the
SPS-1500 looks for the optimal
voltage to run the gauge
•If AutoAnalisys and AutoVolt are disabled (Manual Mode),
increase the voltage; If AutoAnalisys and AutoVolt are enabled
the SPS-1500, try running in a Manual Mode and increase de Set
Voltage until the gauge is communicating.
Packet Size–•Problema de comunicación ya
que el SPS-1500 busca el voltaje
óptimo para detectar el sensor
•Si AutoAnalisys y AutoVolt están desactivados (modo manual),
aumente el voltaje; Si AutoAnalisys y AutoVolt están habilitados
el SPS-1500, intente ejecutar en modo manual y aumente el
voltaje de ajuste hasta que el sensor se comunique.

Error
Possible Cause
Troubleshooting Step
OKAY–•Normal Operation, no errors •SPS is communicating with the gauge
•Operación normal, sin errores •El SPS se esta comunicando con el sensor

© Sercel 2020 - All rights reserved
〉Possible Reason(s)
oSend / Receive connections
reversed
oImproper address and Baud Rate
oNot receiving Modbus request
(Magenta LED by Modbus
connector flashes when SPS
receives Modbus request)
No Modbus communication
18
〉Correction
Check for proper Modbus address and Baud rate on SPS-1500 LCD
RS-485 connections
oMake sure jumpers, J6 & J7, are on SPS-1500.
oMake sure same polarity connection is going from SPS-1500 to
RS-485 adaptor board [e.g. ‘TR-’ from SPS-1500 connects to
TD(A) of RS-485 adaptor].
RS-422 connections
oMake sure jumpers, J6 & J7, are not on SPS-1500.
oMake sure all 4 wires are connected with correct polarity. For
example
o‘TR-’ from SPS-1500 connects to TD(A) of RS-422 adaptor and –
TR+’from SPS-1500 connects to TD (B) of RS-422 adaptor.
