6. Maintenance/Repair
6.6. Replacing terminal board
Step
Honeywell recommends that the transmitter be removed from service and moved to a clean
1
area before servicing.
Depending on your installation, transmitter input wiring sources may contain high voltage.
Disconnect all power from transmitter input sources before accessing the terminal board.
Failure to do so could result in death or serious injury.
Loosen the M3 locking set screw on the battery end-cap (opposite end from display). See item
2
1 in Figure 12. Unscrew and remove the end cap.
Using thumb and forefinger, squeeze the battery connector at top and bottom to disengage the
3
locking mechanism, then pull to disconnect. See item 2 in Figure 12.
Loosen the two battery holder retaining screws (closest to the batteries). See item 3 in Figure
4
12. The screws are captive.
Pull the battery holder out of the transmitter.
5
Disconnect field wiring from terminal board and label it to ease reconnection.
6
Remove and save the 3 screws that attach the terminal board to the housing. Take care
7
because these screws are not captive. See item 4 in Figure 12.
Remove terminal board by disconnecting cable from back of the terminal board. Do not pull on
8
the wires or you could damage them. Instead, depress the latch while pulling on the connector.
Attach connector to new terminal board. Observe correct polarity of the connector. Verify that
9
the cable is latched to the terminal board.
Fasten terminal board with screws from step 7.
10
Re-connect field wiring.
11
Insert the battery holder into the transmitter. Reattach the screws and tighten to 0,4 – 0,6 N-M
12
(3.5 – 5.3 Lb-in).
Re-connect battery connector.
Honeywell recommends lubricating the end cap O-ring with a Silicone Grease such as Dow
Corning #55 or equivalent before replacing the end cap.
Screw the end cap back on and tighten the M3 locking screw.
