2. Indicator Description
(1) PWR：Power indicator. Green, power is normal; No light - power is abnormal.
(2) Weighing Status Indicator: 0:ON-netweight; OFF-gross weight; 1:ON-No load; 2:ON-weight limit exceeded; 3:ON-measuring
stability.
(3) LINK: Multi-status indicator .three colors(Red. Yellow. Green). As follows:
Reference processing mode
Module bus state
LINK indicator state
Normal
No communication of Module
No light
MPU has identified the Module but no
communication
Constant light in green
Serial or parallel port in communication
Green jitter: indicator on 30ms and off 30ms
Parallel power supply insufficient, must
connect to external power supply
Without serial or parallel port in communication
Yellow flicker: indicator on 0.5s and off 0.5s
With serial or parallel port in communication
Yellow indicator off and jitter alternates: indicator off
0.5s and jitter 0.5s
Firmware upgrade failed, re-upgrade
the Module firmware
Without serial or parallel port in communication
Red flicker: indicator on 0.5s and off 0.5s
With serial or parallel port in communication
Red indicator off and jitter alternates: indicator off
0.5s and jitter 0.5s
Hardware failure
Without serial or parallel port in communication
Always on in red
With serial or parallel port in communication
Red jitter quickly: indicator on 30ms and off 30ms
