SI 480E DIN SIZE WEIGHING CONTROLER

7. Error & Treatment

7-1. Load Cell Installation

Error

Cause

Treatment

Remarks

Weight Value is

unstable

1) Load cell broken

2) Load cell isolation

resistance error

3) Weighing part touches other

devices or some weight is on the

weighing part

4) Summing Board Error

1) Measure input/output

resistance of Load cell.

2) Measure Load cell isolation

resistance

1. Input Resistance of
“EXC+” and “EXC-“ is about
400Ω ±30
2. Output Resistance of
“SIG+“ and “SIG-” is about
350Ω ±3.5
3. Isolate Resistance is
more than 100MΩ

Weight Value is

increased regular

rate, but not return

to “Zero”

1) Load cell Error

2) Load cell connection Error

1) Check Load cell

connection

2) Measure Load cell

Resistance

Weight Value is

increased to under

Zero

Load cell Output wire

(SIG+, SIG-) is switched

Make wire correction

Load cell broken or Indicator

connection Error

Load cell Check

Load cell connection Check

Power was “ON” when some weight

is on the load cell.

Remove weight

on the Load cell

“

(Over Load)

1) Load cell broken or Indicator

connection Error

2) Loading over than Max Capacity

1) Load cell Check

2) Load cell

connection Check

3) Remove over

loaded weight
