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.
DC-DC Bad or DC-DC
Chk - (El voltaje medido
por SPS no coincide con
el de SPS)
•Mala conexión a tierra
•Baja resistencia de la señal del
sensor a tierra
•Corriente de línea de señal de
sensor excesiva
•SPS defectuoso
•Verifique las lecturas eléctricas del equipo de fondo (fase-
fase y fase-tierra (megóhmetro con polaridad inversa))
•Pruebe una fuente de alimentación SPS alternativa
•Use un mulltímetro para confirmar que el voltaje MÁX. sea
superior a 45 VCC.

Error
Possible Cause
Troubleshooting Step
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.
Baud Fast –
(Los datos del sensor
están cambiando a una
velocidad superior a la
esperada)
•El voltaje configurado es
demasiado alto
•Ruido del motor afecta a la
modulación actual del sensor
•Desactive Auto Baud y aumente Max Tool Baud a 8-10
•Reiniciar o apagar y encender para reiniciar la etapa de análisis
•Desactive Auto Volt / Auto Analyze con DataWorks. Establezca
el voltaje en ~ 60 VCC.

Error
Possible Cause
Troubleshooting Step
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)
Low Amps –
(La corriente del sensor es
mas baja de la esperada)
•Sensor no esta conectado
•Conexión de alta resistencia en el
motor WYE punto a sensor
•Fusible de señal abierto
•Ajuste de amperaje bajo
establecido en alto
•Verifique las lecturas del fondo del pozo (fase-fase y fase-tierra
(megóhmetro con polaridad inversa))
•Verifique todas las conexiones
•Compruebe el fusible de señal
•Verifique el ajuste de amperaje bajo con DataWorks (15 VDC
nominal)
•Verifique la configuración de alto amperaje con DataWorks (25
VDC nominal)

Error
Possible Cause
Troubleshooting Step
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)
- Check Setting of High amp (25mA normally for SPS-1500)
•Verify Downhole readings (Phase to Phase, Phase-Ground
(Reverse Polarity Megger))
•Replace the SPS-1500
High Amps –
(La corriente del sensor es
mas alta de la esperada)
•Conexión a tierra del cabezal de
pozo deficiente
•Corriente de línea de señal del
sensor excesivo o ruido del motor
en el punto estrella.
•Conéctese al SPS con el software "DataWorks" para establecer
manualmente las siguientes:
- Compruebe la configuración de Low Amp (15 mA normalmente
para SPS-1500)
- Compruebe la configuración de High Amp (25 mA normalmente
para SPS-1500 y 22-26 mA normalmente para SPS-1501)
•Verifique las lecturas del equipo de fondo (fase a fase, fase-
tierra (megóhmetro con polaridad inversa))
•Reemplace el SPS-1500
