Operation

MOUNTING BRACKETS

Normal operation messages appear on the LCD meter to confirm actions or inform you of transmitter status. Operation messages are displayed with other transmitter information, and warrant no action to correct or alter the transmitter settings.

ZERO PASS

The zero value, set with the local zero adjustment button, has been accepted by the transmitter, and the output should change to 4 mA.

ZERO FAIL

The zero value, set with the local zero adjustment button, exceeds the maximum rangedown allowed for a particular range, or the pressure sensed by the transmitter exceeds the sensor limits.

SPAN PASS

The span value, set with the local span adjustment button, has been accepted by the transmitter, and the output should change to 20 mA.

SPAN FAIL

The span value, set with the local span adjustment button, exceeds the maximum rangedown allowed for a particular range, or the pressure sensed by the transmitter exceeds the sensor limits.

LOCAL DSBLD

This message appears during reranging with the integral zero and span buttons and indicates that the transmitter local zero and span adjustments have been disabled. The adjustments may have been disabled by the transmitter security jumper on the transmitter circuit board or through software commands from the HART Communicator. See “Transmitter Security” in Section 2 for information on the position of the security jumper, removal of local zero and span buttons, and for information on the software lockout.

WRITE PROTECT

This message appears if you attempt to change the transmitter configuration data while the security jumper is in the ON position. See “Transmitter Security” in Section 2 for more information about the security jumper.

Optional mounting brackets available with the Rosemount 3051N facilitate mounting to a panel. The standard bracket (option code B4) for use with the Coplanar flange is stainless steel with stainless steel bolts. Refer to Figure 3-2 in Section 3 for dimensions and mounting configurations.

Option B2 is polyurethane painted carbon steel bracket designed for use with the traditional flange. The B2 bracket is supplied with carbon steel bolts and supports panel mounting. Refer to Figure 3-4 in Section 3 for dimensions and mounting configurations.

Option BS is a 316LSST bracket supplied with carbon steel bolts and designed for use in panel mounting with the traditional flange (H2). It is the same bracket used on other RNII nuclear qualified transmitters, including the Rosemount 1153 series D and Rosemount 1154. Refer to Figure 3-4 in Section 3 for dimensions and mounting configurations.
