6.3.6Set Up Sensitivity for Contamination Detection

Each zone may be set up with a sensitivity level at which contamina- tion on the cable is detected. Examples are construction debris and dust.

The most sensitive setting is 20 µA—light contamination will trig- ger an alarm.

The least sensitive setting is 300 µA. This setting requires heavy contamination to activate an alarm.

Increase the setting if nuisance alarms occur.

NOTE

Do not set this setting greater than the sensitivity for water detection setting—for example, if the water detection setting is 50 µA, do NOT set the contamination sensitivity level at 60 µA, or any value greater than 50 µA. If the contamination setting is greater than the water detection setting, contamination alarms will never occur.
