Illegal setup values used: OUT2 select
6
Er 06
=AL2 but A2FN select NONE
Illegal setup values used: Dwell timer
7
Er 07
(TIMR) is selected for both A1FN and
A2FN.
Communication error: receive error due
to parity error, framing error, overrun
9
Er 09
error, receive buffer full error, frame
check-sum error or receive disturbed
10
Er 10
Communication error: bad function code
Communication error: register address

out of range
Communication error: access a non-
12
Er 12
existent parameter
Communication error: attempt to write a
14
Er 14
read only data
Communication error: write a value which
15
Er 15
is out of range to a register
Computing error: Illegal (abnormal)
17

floating point data
Computing error: Arithmetic result

Er 18
overflow or underflow
19
Er 19
Computing error: divided by zero
20
Er 20
Computing error: Illegal BCD data entry
Timing error: A to D conversion data
21
Er 21
error due to overrun
Timing error: check-sum error received
22
Er 22
during multi-chip communication
procedure
Timing error: wrong function code
23
Er 23
received during multi-chip communication
procedure
26
AtEr
Fail to perform
auto-tuning function
Incorrect calibration procedure or
27
CAER
tolerance of analog component too big to
meet specified accuracy
Corrective Action
Check and correct setup values of OUT2 and
A2FN. OUT2 will not perform alarm function if
A2FN select NONE.
Check and correct setup values of A1FN and
A2FN. Dwell timer can only be properly used for
single alarm output.
1.Correct the communication software to meet
the protocol requirements
2. Add a terminating resister to the multi- drop
link (RS-485) to minimize the noise.
3. Use twisted pair wire for RS-485 interface
connection to minimize the noise.
4. Check the polarity of RS-485 interface
connection.
Correct the communication software to meet the
protocol requirements.
Don't issue an over- range address of register to
the slave.
Don't issue a non- existent parameter to the
slave.
Don't write a read only data or a protected data
to the slave.
Don't write an over- range data to the slave
register.
Software bug. Return to factory for repair.
Software bug. Return to factory for repair.
Don't use an equal value for AOLO and AOHI.
Software bug. Return to factory for repair.
A to D converter doesn't work properly. Return
to factory for repair.
1. Correct the multi-chip communication
software to meet the protocol requirement.
2. Return to factory for repair.
1. Correct the multi-chip communication
software to meet the protocol requirement.
2. Return to factory for Repair.
1. The PID values obtained after auto-tuning
procedure are out of range. Retry auto-tuning.
2. Don't change set point value during auto-
tuning procedure.
3 .Don't change Event input state during auto-
tuning procedure.
4. Use manual tuning Instead of auto-tuning.
1. Pay more attention to the calibration
procedures.
2. Return to factory for repair.
