External Alarms
The OS booster is capable of monitoring and reporting external Form-C alarms. Four channels are provided
and each channel is programmed via the Controller Module for NO or NC conditions. For example, NO will
fault when shorted to Common (C) and NC will fault when open to Common (C).The four channels are mapped
to Form-C alarm outputs configured as such via the Ethernet web pages.
(1) Could be critical and bypass if both Rx channels are faulted.
