Medium Flow Compressed Air Dryers - IOMI.
Remote Alarm Connection - Dedicated Dewpoint Alarm
The CDAS HL / OFAS HL / FBP HL dryer controller includes the ability to connect a dedicated dewpoint alarm relay that will activate only
if a dewpoint alarm occurs. This function requires the connection of an additional relay (not supplied) and activation by a trained engineer
using the ADS service software.
Once activated via the ADS service software, the dewpoint alarm functionality is removed from the generic fault relay and assigned to the
dedicated dewpoint alarm output.
The connection to the control board is used to energise the additional alarm relay (not supplied) and is rated at 3-30W@24VDC
On the display screen, a blue box and background around the dewpoint icon and outlet dewpoint value indicates
when the dryer is operating within normal parameters and delivering a dewpoint less than or equal to the
dewpoint setpoint.
Should the outlet dewpoint of the dryer be higher than the dewpoint setpoint, a dewpoint alarm is activated.
This is identified by the normally blue background around the dewpoint icon changing to a yellow background.
With the dedicated dewpoint alarm relay fitted and enabled, the general fault alarm relay icon will not be shown.
The dedicated dewpoint alarm relay will changed state (de-energised), the general fault alarm relay will not change
state (it will remain energised).
