Error Description
Corrective Action
Illegal setup values been used: PV1 is used for both PVMD
and SPMD. It is meaningless for control.
1
Check and correct setup values of PVMD and SPMD. PV
and SV can't use the same value for normal control
Illegal setup values been used: PV2 is used for both PVMD
and SPMD. It is meaningless for control
2
Same as error code 1
Illegal setup values been used: P1-2 or P2-1 is used for
PVMD while PV1 or PV2 is used for SPMD. Dependent
values used for PV and SV will create incorrect result
of control
3
Check and correct setup values of PVMD and SPMD.
Difference of PV1 and PV2 can't be used for PV while PV1
or PV2 is used for SV
Illegal setup values been used: Before COOL is used for
OUT2, DIRT ( cooling action ) has already been used for
OUT1, or PID mode is not used for OUT1 ( that is PB1 or
PB2 = 0, and TI1 or TI2 = 0 )
4
Illegal setup values been used: unequal IN1U and IN2U or
unequal DP1 and DP2 while P1-2 or P2-1 is used for PVMD
or, PV1 or PV2 is used for SPMD or, P1.2.H, P1.2.L, D1.2.H
or D1.2.L are used for A1FN or A2FN.
5
6
Check and correct setup values of IN1U, IN2U, DP1, DP2,
PVMD, SPMD, A1FN or A2FN. Same unit and decimal point
should be used if both PV1 and PV2 are used for PV, SV,
alarm 1 or alarm 2.
Illegal setup values been used: OUT2 select =AL2 but
A2FN select NONE
Check and correct setup values of OUT2 and A2FN. OUT2
will not perform alarm function if A2FN select NONE.
Illegal setup values been used: Dwell timer (TIMR) is
selected for both A1FN and A2FN.
7
Check and correct setup values of A1FN and A2FN. Dwell
timer can only be properly used for single alarm output.
Communication error: bad function code
10
Correct the communication software to meet the protocol
requirements.
Communication error: register address out of range
11
Don't issue an over-range
address to the slave.
register
Communication error: access a non-existent parameter
12
Don't issue a non-existent parameter to the slave.
Communication error: attempt to write a read-only data
14
Don't write a read-only data or a protected data to the slave.
Communication error: write a value which is out of range to
a register
15
Don't write an over-range data to the slave register.
26
Fail to perform auto-tuning function
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.The PID values obtained after auto-tuning procedure are
out of range. Retry auto-tuning.
EEPROM can't be written correctly
29
Return to factory for repair.
Input 2 ( IN2 ) sensor break, or input 2 current below 1 mA
if 4-20 mA is selected, or input 2 voltage below 0.25V if
1 - 5V is selected
38
Replace input 2 sensor.
Input 1 ( IN1 ) sensor break, or input 1 current below 1 mA
if 4-20 mA is selected, or input 1 voltage below 0.25V if
1 - 5V is selected
39
Replace input 1 sensor.
40
A to D converter or related component(s) malfunction
Return to factory for repair.
Check and correct setup values of OUT2, PB1, PB2, TI1,
TI2 and OUT1. IF OUT2 is required for cooling control, the
control should use PID mode ( PB = 0, TI = 0 ) and OUT1
should use reverse mode (heating action), otherwise, don't
use OUT2 for cooling control
