Alarm Contact Connections
The WDG-V Analyzer has five (5) alarm contacts, one (1) Service alarm, one (1)
Data Valid alarm, and three (3) configurable process alarms.
Standard Alarm Connections
Service Alarm Relay This relay is used to determine if there is a problem with the
analyzer. This relay is normally open. Contacts are closed when
in normal mode. The relay will be open when there is a problem
with the analyzer or on loss of power.
Data Valid Relay This relay is used to determine if the output is representative
of the process. This relay is normally open. Contacts are closed
when in normal mode. Contacts are open when there is a prob-
lem with the analyzer, when the analyzer is calibrating, warming
up, when the analyzer is in diagnostic mode, or on loss of power.
Remote Calibration Unit (Optional)
Contact Input There is one Contact Input peripheral on the WDG-V.
An auto calibration can be initiated using the contact input
peripheral. (Only with the RCU option).
Auto calibration must be selected in the Configuration menu.
Remote Calibration Unit
Interface
