The transmitter’s default configuration sets the alarm condition to high (HI)
and the security to off.
Procedure
1. If the transmitter is installed, secure the bus and remove power.
2. Required: Remove the transmitter cover opposite the field terminal
side. Do not remove the instrument covers in explosive environments
when the circuit is live.
3. Slide the Security and Alarm switches into the preferred position by
using a small screwdriver.
Note
The Security switch will need to be in the off position in order to make
any configuration changes.
4. Required: In order to meet explosion-proof requirements, reinstall the
housing cover and tighten so the cover is fully seated with metal to
metal contact between the housing and cover. After the cover is
seated properly, replace the flathead screw located on the bottom of
the housing cover.
