BENTLY 9200-01-01-10-00 Sensor module

Battery VCO Gain

 • Adjustment to match the monitored High battery voltage with the measured High battery voltage. 

• This monitors the input supply voltage on terminals 1 and 2.

 • Battery voltage Gain is calibrated for accurate High Battery Voltage Alarms

• Adjustment to match the monitored Low battery voltage with the measured Low battery voltage. 

• Battery voltage Offset is calibrated for accurate Low Battery Voltage Alarms.

Adjusting Battery Gain and Offset 

• Use an adjustable power source 

• Measure the input supply voltage being fed from the power source 

• Set the power source for 28 volts DC

 • Adjust the Gain until the monitored voltage reads 28 volts 

• Set the power source for 10 volts

 • Adjust the Offset until the monitored voltage reads 10 volts

 • Repeat these steps until no adjustment is needed

Oil Pressure Gain

 • Oil pressure sensor input, terminals 68(+) and 69(–).

 • Factory Calibrated for a 0–75 psi signal over a 4–20 mA range. o 4 mA = 0 psi o 20 mA = 75 psi 

• Designed to accept a 4–20 mA or 1–5 volt transducer or a passive resistive type, 0 – 200 Ω. 

• Sensors can have a Direct or Indirect relationship o Direct – Increase in resistance, mA, or volts is an Increase in Pressure o Indirect – Increase in resistance, mA, or volts is a Decrease in Pressure

• Resistive sensors are commonly a direct relationship. 

• Adjust the Oil Pressure Gain, the Calibration menu will provide a monitored reading that will be compared to a measured reading. 

• Adjust gain until EGCP-2 monitored reading matches actual reading.
