4.4 Load Sensing System
4.4-1 Green Power LED is not Flashing
1. Loose or broken wires #60 and #02 at platform
terminal block.
Check for connections. Check for voltage (12V).
2. Load cell has lost its calibration. Refer to calibration procedure for recalibration of
load cell.
4.4-2 Load Cell red Alarm LED is ON (with platform empty)
1. Load cell has lost its calibration. Refer to calibration procedure for recalibration of
load cell.
4.4-3 Red Error LED is ON
1. Open safety contact circuit. Check for connections with wires #60 and #162 at
platform terminal block and base terminal block.
Check resistor R13 for 680 ohms.
4.4-4 Load Cell red Alarm LED is OFF (with platform overloaded)
1. Open safety contact circuit. Check for connections with wires #60 and #162 at
platform terminal block and base terminal block.
Check resistor R13 for 680 ohms.
4.4-5 Platform Indicator Light does not turn ON
1. Defective lamp. Check lamp. Replace if defective.
2. Defective load cell. Defective if 0V is measured between wire #82 and
#02 from platform terminal block.
4.4-6 Audible Alarm does not turn ON
1. Defective alarm BP3. Check alarm. Replace if defective.
2. Open or defective diode D118. Check diode. Replace if defective.
3. Load cell circuit not operating. Check for connections with wires #02 and #118 at
platform terminal block.
4. Defective load cell. Defective if 0V is measured between wire #118 and
#02 from platform terminal block.
