To improve field access to wiring or to better view the
optional LCD display:
1. Loosen the housing rotation set screw.
2. Turn the housing up to 180° left or right of its
original (as shipped) position.
3. Retighten the housing rotation set screw.
NOTE
Do not rotate the housing on each transmitter more than 180 degrees without first performing a
disassembly procedure (see Section 2 of the 3051S ERS System reference manual
(00809-0100-4804) for more information). Over-rotation may sever the electrical connection
between the sensor module and feature board electronics.

If the 3051S ERS Sensor is equipped with alarm and security hardware switches, verify the
desired configuration (default: alarm = HI, security = OFF).
1. If the sensor is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminals side. Do not remove the housing
cover in explosive environments.
3. Slide the security and alarm switches into the preferred positions by using a small
screwdriver.
4. Reinstall the housing cover so that metal contacts metal to meet explosion-proof
requirements.
