Rosemount 1154 Series H

1.

Disengage the header assembly board (4) as described in Step 4 of 
the electrical housing disassembly procedure on page 5-3. You need 
not remove the module shroud from the electrical housing for 
checkout.

2.

Jump connections 1 and 2 on the header assembly board (see Figure 
5-1).

3.

Using a low-voltage ohmmeter, check the resistance between the 
jumper wire and the module shroud. This resistance should be 
greater than 10 M

Ω

. Remove the jumper wire.

4.

Jump connections 3 and 4 on the header assembly board and repeat 
Step 3 (see Figure 5-1).

NOTE

The above procedure does not completely test the sensing module. If circuit 
board replacement does not correct the abnormal condition, and no other 
problems are obvious, the transmitter should be replaced.

DISASSEMBLY 
PROCEDURE

NOTE

Numbers in parentheses refer to item numbers in Figure 5-2 on page 5-6.

NOTE

The Rosemount 1154 Series H Pressure Transmitter contains electronic 
circuit boards which may be static sensitive.

Electrical Housing 
Disassembly

1.

The signal terminals and the test terminals are accessible by 
unscrewing the cover (1) on the terminal side. This compartment is 
identified as “Terminal Side” on the nameplate. The terminals are 
permanently attached to the housing and must not be removed.

2.

Circuit boards are located in a separate compartment identified as 
“Circuit Side” on the nameplate. Remove power from the transmitter 
before removing the circuit cover. Unscrew the cover (1) on the circuit 
side to access the circuit boards. A special cover wrench (Rosemount 
Part Number 01153-0382-0001) is available from Rosemount to 
remove and replace the housing covers.

3.

Unplug the amplifier board (6) after removing 3 holding screws (7). 

4.

The header assembly board (4) is permanently attached to the sensor 
module within the module shroud (8) and contains the 
temperature-compensating resistors. Carefully pull this board off the 
bayonet pins and rotate the board 180° about the axis formed by the 
connecting leads. This allows access to the calibration board (5). 

5.

Disconnect the calibration board (5) by aligning the zero and span 
adjust screws so that their slots are perpendicular to the board. 
Remove the board by inserting a 6-32 screw in the rivnut on the 
board, and carefully pull the board off the bayonet pins.

6.

If replacement of the zero and span adjustment screws (10) is 
necessary, remove the nameplate (13) and detach the snap rings (12) 
inside the housing.
