Where the sensor is a negatively powered Eddy Current Probe, the module
performs two additional checks:
• The transducer power supply that is provided by the module is
delivering at least 2 mA
• The transducer DC/bias voltage remains negative
These two checks are based on hardware monitoring, which is designed to
detect any discrepancy quickly, and are referred to as 'wire-off ' detection. Once
a wire-off condition has been detected, this failure is latched for 30 seconds.
Any recurrence that causes this timer to be restarted, such that recovery from a
wire-off condition, is 30 seconds after the last detected event. This measure
aims to make sure that signals have stabilized.
