WARNING
Remove power from the transmitter before removing either the
terminal side or circuit side cover (1).
Electronics Assembly Removal
1. The electronics assembly (4) is accessible by unscrewing the
cover (1) on the electronics side. This compartment is not
specifically identified by notes on the housing (5), but is located
opposite of the side marked “FIELD TERMINALS.”
2. Before removing the electronics assembly, align the zero and
span adjustment screws so that their slots are perpendicular to
the board, as shown in Figure 5-3.
3. Unscrew the two 6-32 captive screws holding the electronics
assembly to the housing and pull the electronics assembly from
the housing (see Figure 5-3).
4. Unclip and disconnect the connector plug from the top of the
sensor module (8) to completely remove the electronics assembly
(see Figure 5-4). To remove connector plug, apply even pressure
to both clips and pull the connector body up from the sensor
module. Do not pull on the cable wires.
Terminal Block Removal
1. The signal terminals and test terminals are accessible by
unscrewing the cover (1) on the terminal side. This compartment
is identified by the “FIELD TERMINALS” notes on the sides of the
electronics housing (5).
2. The terminal block assembly (6) is removed by removing the two
6-32 screws and pulling the terminal block assembly out of the
housing (see Figure 5-5).
IMPORTANT
The Electronics Housing (5), Housing Set Screws (12) and
Sensor Module (8) Assembly cannot be disassembled in the
field. The Housing Set Screws (12) are held in place by a thread lock
compound (Loctite
®
266) applied at the factory during manufacturing.
If this interface is damaged, the qualification of the transmitter
becomes invalid. For any maintenance that requires the sensor
module (8) be removed from the housing (5), please contact
Rosemount Nuclear Instruments, Inc.
