The RDM comes with a built in alarm contact. This
contact will close anytime either a sensor or control error
is detected by the control. The contact will remain closed
until the error is cleared. To clear the error message on
the RDM and turn off the alarm relay, refer to the control
Data Brochure. This contact will also close if a Warning in
the control is triggered. However, if a warning is triggered,
the alarm contact will only remain closed for 60 seconds.
After 60 seconds, the warning message will continue to be
displayed, but the alarm contact will be shut off. To clear
the warning message, the keypad of the RDM must be
pressed as described in the control Data Brochure.
Between terminals 1 and 2, the contact is capable of switching a low voltage signal that
is less than 0.5 Amps. This switch can be used to operate a low voltage alarm device
directly, or it can be used to energize an external relay to trigger a line voltage or high
current alarm device.
STEP FIVE
INSTALLING THE FRONT COVER
Align the hinges on the bottom of the front cover with the
bottom of the RDM mounting base. Pivot the front cover
around the bottom hinges and push the top against the
mounting base until it snaps firmly in place.
