A094
Heatsink Overheated
Description
IGBT heatsink temperature too high.
Event
IGBT power heatsink overheated even if the cooling fan is on (see also
A096
and
A099
).
Possible cause
•
Ambient temperature exceeding 40 °C.
•
Too high motor current.
•
Excessive carrier frequency for the application required.
Solution
1. Check ambient temperature.
2. Check motor current.
3. Decrease IGBT carrier frequency (contact ENERTRONICA SANTERNO
’s Customer
Service).
A096
Fan Fault
Description
Fan alarm.
Event
Power heatsink overheated with fan locked or disconnected or faulty (see also
A094
and
A099
).
Possible cause
Fan locked or disconnected or faulty.
Solution
Replace fan.
A099
Sensor 2 Fault
Description
Fan sensor 2 fault.
Event
Power heatsink overheated with cooling fan off (see also
A094
and
A096
).
Possible cause
Failure in temperature control device and/or cooling system.
Solution
Please contact ENERTRONICA SANTERNO
’s Customer Service.
A102
A103
A104
A086
Current Input > 20 mA
Description
A102:
REF Current input (4
20mA or 0
20mA) greater than 20mA
A103:
AIN1 Current input (4
20mA or 0
20mA) greater than 20mA
A104:
AIN2 Current input (4
20mA or 0
20mA) greater than 20mA
A086:
XAIN5 Current input (4
20mA or 0
20mA) greater than 20mA
Event
A current value greater than 20mA has been detected over one input (REF, AIN1, AIN2, XAIN5)
set with the following ranges: 4
20mA or 0
20mA.
Possible cause
•
Wrong setting of
SW1
on the control board (except for
A086
).
•
Failure in the current signal source.
Solution
1. Check setting of SW1(except for A086).
2. Check the current signal source.
