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.

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
