Error Description
Reason/Measure
1
BAT_CHANG
Battery discharged
Change battery and reset the actuator operating range
2
BAT_EMPT
Pre-alarm for discharged
battery
Change battery as soon as possible reset actuator
operating range after battery change
3
TORQUE_O
Torque alarm, OPEN
Check selected pre-alarm torque value, check actuator,
value and rearing (if used) for increased friction and
actuator probably used below permitted ambient
temperature (oil viscosity)
4
TORQUE_C
Torque alarm, CLOSED
Check selected pre-alarm torque value, check actuator,
value and rearing (if used) for increased friction and
actuator probably used below permitted ambient
temperature (oil viscosity)
5
TEMP_MOT
Critical motor temperature
Once motor-alarm temperature is achieved, the actuator
is only available with reduced speed, until the motor is
sufficiently cooled down
6
TEMP_ELC
Critical electronics
temperature
Once electronics-alarm temperature is achieved, the
actuator is only available with reduced speed, until the
motor is sufficiently cooled down
7
24_VOLT
Breakdown of external DC 24
Volt supply
Actuator is still working, however, if main power lost,
output contact will not be able to maintained, nor analog
output
8
CNT_TRQ
Exceed torque switch off limit
(default limit value: 10,000)
Check valve working status
9
STEP/SH
Switching frequency of
1200/hour exceeded
Increase deadzone (P3.8 menu), to decrease the
responding times
10
LOAD_EXC
Modulating torque value
exceeded
Alarm can be reset with user interface; it will be reset
automatically after 10 min
11
SETPOINT
Input exceed the limit
Please check current supply, make sure the current is
within 3.6mA~20.8mA
12
ACT_TYPE
Miss matching of actuator
model
Please check the actuator setting type or model in menu
P5.6
13
AC_PHASE
Miss matching of phase of
power supply
Please check AC power supply phase number setting in
menu P5.7, check the power supply as well
