Defender 5000 Indicators Service Manual
TD52XW
Remove the four hex head screws from the rear housing.
Open the housing by carefully pulling the front housing forward.
Once all connections are made, reattach the front housing.
The screws should be tightened to 2.5 N•m (20-25 in-lb) torque to ensure a watertight seal.
1.7.2 Scale Base Without Connector
For connecting bases (which do not have the connector) to a TD52P or TD52XW, a cable gland kit (P/N
30379716) is available as an accessory.
Removing the pre-installed Load Cell connector and wiring harness
Before doing the connections, remove the pre-installed Load Cell connector and wiring harness by following
the steps below.
1.
Open the housing by carefully pulling the front housing forward.
2.
Unplug the white load cell connector from the main PCBA board (red circle).
3.
Remove the metal terminal (Figure 1-1, item 12) connector from the rear housing.(green circle)
Installing Cables and Connectors
In order to meet certain electrical noise emission limits and to protect the TD52P and TD52XW from
external influences, it is necessary to install a ferrite core on the load cell cable connected to the terminal.
The ferrite core is included with the terminal.
To install the ferrite, simply route the cable through the center of the core and then take one wrap around
the outside of the core and route the cable through the center again. Either the complete cable or the
individual wires can be wrapped through the ferrite. This should be done as close to the enclosure as
possible. See Figure 1-5.
Figure 1-5
Main Board Wiring Connections
Once the TD52P and TD52XW enclosure is open, connections can be made to the terminal strips on the
main board, as shown in Figure 1-6.
