Error Description
Corrective Action
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 PB
= 0, and / or TI = 0 )
4
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 register address to the slave.
Communication error: attempt to write
a read-only data or a protected 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
EEPROM can't be written correctly
29
Return to factory for repair.
Input sensor break, or input
current below 1 mA if 4-20 mA is
selected, or input voltage below
0.25V if 1 - 5V is selected
39
Replace input sensor.
40
A to D converter or related
component(s) malfunction
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.Use manual tuning instead of auto-tuning.
5. Don’t set a zero value for TI.
4. Don't set a zero value for PB.
6. Touch RESET key
Cold junction compensation for
thermocouple malfunction
30
Return to factory for repair.
Check and correct setup values of OUT2, PB, TI 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.
No product returns may be accepted without a completed Return Material Authorization (RMA) form.
