Description & Reason
Corrective Action
4 ER04
Illegal setup values used:
COOL is used for OUT2
when DIRT (cooling action) is used for OUT1, or
when PID mode is not used for OUT1 (PB =0 and/or
TI=0)
Check and correct setup values of OUT2, PB1, PB2, TI1,
TI2 and OUT1. IF OUT2 is needed for cooling control, the
controller should use PID mode (PB
≠
0 and TI
≠
0) and
OUT1 should use reverse mode (heating action), otherwise,
OUT2 cannot be used for cooling control.

ER10
Communication error: bad function code
Correct the communication software to meet the protocol
requirements.
11 ER11
Communication error:
register address out of range
Do not issue an over range address of register to the slave.
14 ER14
Communication error:
attempt to write a read only
data
Do not write a read only data or a protected data to the
slave.
15 ER15
Communication error:
write a value which is out of
range to a register
Do not write an over range data to the slave register.
16 EIER
Event Input Error:
Two or more event inputs are set
to the same function
Do not set the same function in two or more Event Input
Function parameters (E1FN through E6FN).
26 ATER
Auto-Tuning Error:
Failed to perform auto-tuning
function
1. The PID values obtained after auto-tuning process are
out of range, retry auto-tuning.
2. Do not change the set point value during auto-tuning
process.
3. Use manual tuning instead of auto-tuning process.
4. Do not set a zero value for TI.
5. Do not set a zero value for PB.
6. Touch RESET key.

EEPR
EEPROM can't be written correctly
Return to factory for repair.
30 CJER Cold junction compensation for Thermocouple
malfunction
Return to factory for repair.
39 SBER
Input sensor break, or input current below 1mA if 4-
20mA is used, or input voltage below 0.25V if 1-5V is
used
Replace input sensor.
40
AADER A to D converter or related component(s) malfunction
Return to factory for repair.
