Medium Flow Compressed Air Dryers - IOMI.
Dewpoint Alarm – General Fault Relay Activated
Dewpoint Alarm – Dedicated Dewpoint Relay Fitted and Activated
Important Notes:
Dewpoint Alarm Delay at Start Up
Following application of power there is a dewpoint alarm delay of 30 minutes (customisable by a trained engineer using the Parker
ADS service software). During the alarm delay period, should the dryer outlet dewpoint be worse than the dewpoint alarm setpoint,
the alarm relay will not be triggered.
Dewpoint Alarm Fault - Activation Delay
Once the dewpoint alarm delay at start-up period has passed, any dewpoint fault is subject to an alarm relay activation delay.
Should the dryer outlet dewpoint be worse than the dewpoint alarm setpoint, the controller will not activate the general alarm
relay (or dewpoint alarm relay if tted and activated) unless the outlet dewpoint fault is longer than 10 minutes (default value is
customisable by a trained engineer using the Parker ADS service software)
