Alarm
HEC002-A/HEC006-A 9-4
9.5 Troubleshooting
Troubleshooting methods when the alarm appears is explained as follows.
Table9-4 Troubleshooting
Code Reason for alarm setting Cause
ERR00
(1) High level noise on the power line,
ground line, or temp. sensor line.
(1) Move the product to an environment with little
noise, turn ON the power supply. If there is no
alarm, it was caused by noise. Please consult with
us.
ERR01
(1) High level noise on the power line,
ground line, or temp. sensor line.
(1) Move the product to an environment with little
noise, turn ON the power supply. If there is no
alarm, it was caused by noise. Please consult with
us.
ERR03
(1) The EEPROM data was destroyed by
high level noise.
(1) Move the product to an environment with little
noise, turn ON the power supply. If there is no
alarm, it was caused by noise. Please consult with
us.
ERR04
(1) Controller EEPROM data has been
corrupted due to high level noise.
(2) Writing frequency to EEPROM
exceeds product guarantee value
(1,000,000 times). (1)(2)Request a repair if the alarm can
’t be reset.
ERR11
(1) DC output voltage of product is
reduced.
(2) The fan at the power supply stops.
(3) The large amount of dust is attached to
the filter.
(4) Voltage sag happens.
(1) Check the power voltage is 100 to 240VAC
(2) Remove foreign matters which might stop the
fan.
(3) The inside of the power supply can get hot.
Eliminate the dust on the filter.
(4) If voltage sag lasts over specified value of
50msec, the output of DC power supply reduces
and the alarm occurs. Ensure that voltage sag
does not happen.
ERR12
(1) Internal temp. sensor value exceeds
the high temp. cutoff temperature.
(2) Flow rate of circulating fluid is zero.
(1) Check the set value for high temp. cutoff
temperature and confirm the temperature really
reaches this value.
(2) If the flow rate of the circulating fluid is zero, the
temperature of circulating fluid can
’t be detected
and might increase. Confirm the flow of circulating
fluid isn
’t stopped by valves etc.
ERR13
(1) Internal temp. sensor value is lower
than low temp. cutoff temperature.
(2) Flow rate of circulating fluid is zero.
(1) Check the set value for low temp. cutoff temp.
and confirm the temperature really reaches this
value.
(2) If the flow rate of the circulating fluid is zero, the
temperature of circulating fluid can
’t be detected
and might increase. Confirm the flow of circulating
fluid isn
’t stopped by valves etc.
ERR14
(1) Ambient temp is high.
(2) Dust is stuffed on filter.
(3) Flow rate is zero.
(4) The pump breaks.
(5) The fan fails.
(1) Decrease ambient temp.
(2) Eliminate dust on the filter.
(3)(4) If flow rate of circulating fluid is zero, the
temperature of circulating fluid can
’t be measured
and the temperature of heat exchanger may
increase. Ensure the circulating fluid is allowed to
flow.
(5) Confirm the fan for radiating thermo module is
working.
