Status Description
1. WATER: The most normal indication when no oil is detected, and the sump is not dry.
2. OIL alarm: Small oil layer was detected.
3. HIGH OIL alarm: A thick oil layer was detected, thicker than Oil 1 Alarm.
4. AIR: The sensor is out of water or oil (the sump is dry).
5. SIGNAL TOO HIGH: Indicated a possible sensor failure or an improper floatation (too
deep or submerged).
6. SIGNAL TOO LOW: Indicated a possible sensor failure.
The Lights on the front panel will show FAIL status for any fail indication. The details about the
nature of the failure can be seen through the PC, Modbus, LCD or wireless communication,
whatever option implemented.
Parameters Description
•
Water Calibration
A value (in μA) that is equal to sensor output when floating properly in clean water. If the
measured signal is more than Water Calibration - Oil Delta + Hysteresis, then the status is
WATER.
•
Oil Delta
A value (in μA) below Water Calibration.
If sensor's signal is less than Water Calibration - Oil Delta - Hysteresis then the status is OIL
alarm.
•
High Oil Delta
A value (in μA) below Water Calibration.
If sensor's signal is less than Water Calibration - High Oil Delta - Hysteresis then the status is
HIGH OIL alarm.
•
Air Calibration
A value (in μA) that is equal to sensor output in Air, without any liquid around.
Note: For ID-223, this is the value when the sensor is held by a non-metallic spacer at least
2 cm above the bottom flange of the cage.
•
Air Delta
A value (in μA) above Air Calibration. It is used for ensuring Air status even if the sensor is a bit
wet or doesn’t sit correctly on the bottom flange.
If measured sensor's signal is less than Air Calibration + Air Delta – Hysteresis then the status is
AIR.
