1. LOADRITE E2750 WEIGHING SYSTEM

The LOADRITE E2750 weighing system measures the weight of loads lifted by refuse trucks.
The heart of the system is the E2750 Indicator, which provides a keypad for entering instructions and an LCD screen to display

weights and messages.
The Indicator has internal memory which stores settings and data even when switched off.
The E2750 is installed in the cab of the truck and is connected to sensors on the lifting arms.

1.1. WEIGHT MEASUREMENT

The E2750 Indicator measures the sensors as the bin is raised and lowered. The Indicator converts the sensor signals into a
weight reading and displays the value.

An electronic position sensor mounted on the lift arms ensures that the weight measurements are taken at the same position
each time.

The weight of the lifting arms are zeroed out when the system is calibrated. In addition, on most truck styles the bin is weighed
on the way up (full), and then again as it is lowered (empty). These two weights are subtracted from each other, so that only the
weight of the contents (bin payload) is displayed. The bin payload is then added to the truck total.

NOTE: On some truck types, only total bin and contents weight are measured, for example, Hook Lift trucks. In this case, there
may be no position sensor. Refer to section 2.2 (page 2-9) for more details.

1.2. DISPLAY

The E2750 display gives instructions and information, along with the measured or total truck weight.
The display is backlit for ease of operation in low light conditions.
