E. Inline Gage Transmitter Orientation

The low side pressure port (atmospheric reference) on the inline gage transmitter is located in the neck of the transmitter, behind the housing. The vent path is 360° around the transmitter between the housing and sensor. (See Figure 3.)

Keep the vent path free of any obstruction, including but not limited to paint, dust, and lubrication by mounting the transmitter so that the contaminants can drain away.

STEP 2: CONSIDER HOUSING ROTATION

To improve field access to wiring or to better view the optional LCD display:

1.Loosen the housing rotation set screw.

2.First rotate the housing clockwise to the desired location. If the desired location cannot be achieved due to thread limit, rotate the housing counter clockwise to the desired location (up to 360° from thread limit).

3.Retighten the housing rotation set screw.

STEP 3: SET THE JUMPERS

If alarm and security jumpers are not installed, the transmitter will operate normally with the default alarm condition alarm high and the security off.

1.If the transmitter is installed, secure the loop, and remove power.

2.Remove the housing cover opposite the field terminal side. Do not remove the instrument cover in explosive atmospheres when the circuit is live.

3.Reposition the jumper. Avoid contact with the leads and the terminals. See Figure 4 for the location of the jumper and the ON and OFF positions.

4.Reattach the transmitter cover. The cover must be fully engaged to comply with explosion-proof requirements.
