2.10.2 Reed Switch (Hardware Alarm)
The
Trade Route
system is equipped with a “weigh position” alarm system, consisting of a reed switch and a
magnet, which operates when the 920i is off. When the 920i indicator is on, the system software automatically
monitors the weight on the scale and alerts the operator if the scale is in the weigh position via the LED located on
the weigh center. The reed switch and magnet are installed at the factory, but must be electrically connected at
system installation. The reed switch and magnet are mounted on the double load cell module of a three-point
system and on one of the modules in a four-point system.
1. Bring wire into the weigh center through the strain relief.
2. Install spade terminals onto the reed switch cable.
3. Connect the cable to terminal as shown in Figure 4-5.
4. Test the alarm by raising the scale. When the scale is in the weigh position the alarm is activated. Lowering
the scale into the transport position should turn the alarm off.

2.10.3 Power (Truck) Cable
Included with the electronic weigh center is a three-conductor 14-gauge cable that supplies power to the electronic
weigh center. This cable is referred to as the truck cable. The truck cable has the following wiring color code:
BLACK – Negative
WHITE – Positive
GREEN – Chassis Ground
1. Route the power cable through the strain relief in the electronic weigh center to the nearest switched and
fused connection. The weigh center power is connected to a switched circuit to ensure the weigh center is
only on when the key is on.
2. Insert the 7.5A blade fuse into the blade fuse holder and connect one end of the blade fuse holder to the
white conductor, using the included butt splice. Spade terminals are provided to create an insulated
connection.
3. Connect other side of blade fuse holder to a power source or positive battery terminal.
4. Connect the black conductor to the negative battery terminal.
5. Attach GREEN wire to chassis ground.
6. Plug the power cable into the corresponding connector in the electronic weigh center. See Figure 4-5.
7. With the electronic weigh center switch OFF, turn the truck key on and confirm power by viewing the LED
on the circuit board.
8. Turn off the power source.
