Annex G Troubleshooting of General Problems
  When  the  instrument  work  abnormally,  if  there  is  any  error  prompt,  please  handle  it 
according  to  A-1  “Explanation  of  Error  Prompt  Information”.  If  the  working  procedure  is 
abnormal, auxiliary display can be set to work step state (SET 0quantitative scale parameter 
7B = 4, catchweigher parameter 17B = 4), to observe at which step the action stops. Analyze what 
conditions for entering next step is not met according to description table of relative procedure 
step, and then execute corresponding adjustment. 
  Handling methods of general problems are listed in Table G-1.

Instrument  weighing 
abnormal 
Wiring of transducer is 
wrong. 
Incentive  power 
terminal  of  four-wire 
connection  is  not  short 
connected  to 
corresponding incentive 
feedback terminal. 
Weighing  platform  or 
the  transducer  has 
problems. 
Incentive power load of 
transducer is too large, 
making  incentive 
voltage decrease. 
Check  transducer 
wiring 
In  case  of  four-wire 
connection,  EX+  and 
SEN+ terminalEX-and 
SEN- terminals should 
be short connected. 
Check  whether  output 
signals  of  weighing 
platform and transducer 
are normal 
The  load  current  of 
incentive power  should 
not  be  more  than 
80mA. 
During  parameter 
setting,  certain 
parameters  cannot  be 
displayed. 
This parameter value is 
wrong,  exceeding 
display range.
