CHARGING THE BATTERY
To ensure optimum performance of the TWR-5, the internal battery may need to be charged for up to 16 hours before first time use.
Important: If the TWR-5 is to be stored for an extended period, this should be in a cool dry place. For optimum battery life, store the TWR-5 at 50% capacity.
Always charge the battery indoors.
1. Connect the power adapter at the base of the unit and plug the TWR-5 into a power outlet and switch ON. The charging icon will display on the screen.
Warning: The power adaptor is intended for indoor use only. Do not expose to rain or dampness. The TWR-5 must not be powered by any power source exceeding 13 V, as it may damage the product and void the warranty.
2. When the charge shows 100% the TWR-5 is ready to use with or without the power adapter.

Note:
- When the TWR-5 is in use, the battery icon will display and show remaining charge.
- When using the scale and the charge level falls below 10% the battery icon will flash with a red outline. You will have about 30 minutes to complete the weighing session before the TWR-5 must be charged.
- When the charge level becomes critical the unit will shut down.
- To check remaining run time at current settings, from the Home screen, go to Settings > About > Battery.
- The battery error icon will display if the battery is too hot (above +45C) or too cold (below 0C). The Scale will keep operating while plugged in but will not charge properly until at room temperature.
INSTALLATION
- Installing the TWR-5
- Installing the loadbars
- TWR-5 Position
- Installing the Antenna Panel
- Attaching the Antenna Panel
The TWR-5 can be placed on a table top or mounted on the bracket supplied.
Installing the Scale bracket
The bracket can be mounted on a flat vertical surface, a round post, or a rail.
To mount the bracket on a flat vertical surface, or a round wooden post, use the 4 x tek screws included with the unit.

To mount the bracket on either a vertical or horizontal bar, use the ‘U’ bolts included with the unit.

Important: It is not recommended to mount the TWR-5 bracket on the weighing crate or chute as interaction with the scale can impair weighing performance.
If using loadbars, follow these steps:
1. Select a weighing site that provides a solid, level and well drained surface.
2. Ensure the loadbars and platform are well secured and clear of any obstructions.
3. Either bolt the loadbars to the concrete pad or locate them on studs set into the concrete. It is important that the loadbars and platform sit flat without any rocking or twisting to avoid weighing inaccuracies.
Note: It may be necessary to shim the loadbars or platform to ensure there are no twisting pressures within the platform. Weights should be evenly distributed over the top of the weigh bars.
4. For Wired Loadbars: Connect the loadbar cables to the TWR
For Wireless Loadbars: The TWR must be within 8-10m of the loadbars. Refer to the Gallagher Loadbars Instructions for further installation information.
A beep will sound indicating a successful connection / disconnection of the loadbars.
WARNING – Do not weld the loadbars or any structure that they are attached to. Loadbars contain sensitive electronic devices which will be damaged by welding. Damage caused by welding will void warranty.
Clear of the platform to ensure it does not interfere with the flow of animals during the weighing cycle
Within easy reach of the loadbar leads
Within easy reach of the operator (for manual weighing)

The TWR-5 has an internal reader, that when connected to a Gallagher Antenna panel will capture the Electronic ID tag data.
To weigh animals in a crush, you will need:
- Gallagher Antenna Panel kit
- 4m Antenna Extension Cable G05600 or 6m Antenna Extension Cable G05602
Note: A short adapter cable G05601 may be required on early versions of the Sheep Auto Drafter made prior to 2018.
To mount your Antenna panel, refer to the instructions included with the panel.
Important: Use the defined mounting holes, because drilling through the Antenna Panel will damage the antenna.
1. Ensure the TWR-5 is turned OFF.
2. On the Antenna Panel, unscrew the Amphenol connector locking nut from the Amphenol socket and pull it down to unplug from the Antenna Panel.

3. Connect the extension cable to the Amphenol connector and tighten, then connect the other end of the extension cable to the Antenna connector on the base of the TWR-5.
4. Tighten the locking nut.
5. Refer to Connecting Equipment to the TWR-5 (p. 8) to complete the EID Reader connection on the TWR-5.
