Loadrite L2150 User Manual
10. APPENDIX A: SYSTEM SPECIFICATIONS
10.1. WEIGHING ACCURACY
Typical accuracy is within 1% for most bucket loaders. This may vary with different machine types, installation options, and the
operating environment.
10.2. MINIMAL WEIGHING DELAY
Weighing delay is minimal, because the weighing function is carried out during a normal lift.
10.3. POWER REQUIREMENTS
Supply voltage
12 to 32V DC
Supply current
Loadrite Indicator: 160mA typical, 350mA max.
Loadrite printer: 50mA standby, 4A peak.
Automatic transient
suppression
Exceeds relevant SAE specifications for DC automotive power supply transients.
10.4. PHYSICAL SPECIFICATIONS
LCD display
Backlit; 3.8in (diagonal); QVGA.
Tactile keypad
Backlit; Numeric and special functions.
Weight
1.5 kg (3.2lb)
Dimensions
W145 x L240 x D110mm
(5.7 x 9.4 x 4.3in)
10.5. ENVIRONMENTAL SPECIFICATIONS
Operating temperature
-10°C ~ 50°C (14°F ~ 122°F)
Storage temperature
-50°C ~ 100°C (-58°F ~ 212°F)
Indicator

Trigger
Trigger 1: Magnetic or Optical. Pull-up resistor with switch to ground.
Trigger 2: Rotary. Pulse width modulated 0-5V.
Serial communications
RS232C protocol to printer and Loadrite Data Module.
10.7. CLOCK
Built-in clock
