Alarm Contacts
There are 5 alarm contacts in the WDG-V, 1 service alarm, 1 data valid
alarm, and 3 configurable process alarms.
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 nor-
mal mode. Contacts are open when there is a problem with the analyzer,
when the analyzer is calibrating, warming up, when the analyzer is in
diagnostic mode, or on loss of power.
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 sensor configuration menu.
Remote Calibration Unit Interface
The WDG-V has 5 solenoid valve drivers that are compatible with AM-
ETEK’s remote calibration unit (RCU).
See Wiring Section for interface details.
