ALARM 14, Earth (ground) fault
There is current from the output phases to earth, either in
the cable between the frequency converter and the motor
or in the motor itself.
Troubleshooting:
•
Remove power to the frequency converter and
repair the earth fault
•
Check for earth faults in the motor by measuring
the resistance to ground of the motor leads and
the motor with a megohmmeter
•
Perform current sensor test
ALARM 15, Hardware mismatch
A fitted option is not operational with the present control
board hardware or software.
Record the value of the following parameters and contact
the Trane supplier:
•
15-40 FC Type
•
15-41 Power Section
•
15-42 Voltage
•
15-43 Software Version
•
15-45 Actual Typecode String
•
15-49 SW ID Control Card
•
15-50 SW ID Power Card
•
15-60 Option Mounted
•
15-61 Option SW Version (for each option slot)
ALARM 16, Short circuit
There is short-circuiting in the motor or motor wiring.
Remove power to the frequency converter and repair the
short circuit.
WARNING
Disconnect power before proceeding.
WARNING/ALARM 17, Control word timeout
There is no communication to the frequency converter.
The warning will only be active when 8-04 Control Timeout
Function is NOT set to OFF.
If 8-04 Control Timeout Function is set to Stop and Trip, a
warning appears and the frequency converter ramps down
until it trips then displays an alarm.
Troubleshooting:
•
Check connections on the serial communication
cable
•
Increase 8-03 Control Timeout Time
•
Check the operation of the communication
equipment
•
Verify a proper installation based on EMC
requirements
WARNING/ALARM 22, Hoist mechanical brake
Report value shows what kind it is.
0=The torque ref. was not reached before timeout.
1=There was no brake feedback before timeout.
WARNING 23, Internal fan fault
The fan warning function is an extra protective function
that checks if the fan is running/mounted. The fan warning
can be disabled in 14-53 Fan Monitor ([0] Disabled).
Troubleshooting
•
Check fan resistance
•
Check soft charge fuses
WARNING 24, External fan fault
The fan warning function is an extra protective function
that checks if the fan is running/mounted. The fan warning
can be disabled in 14-53 Fan Monitor ([0] Disabled).
Troubleshooting
•
Check fan resistance.
•
Check soft charge fuses.
WARNING
There is a risk of substantial power being transmitted to
the brake resistor if the brake transistor is short-circuited.
WARNING/ALARM 28, Brake check failed
The brake resistor is not connected or not working.
Check 2-15 Brake Check.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not reset until the
temperature falls below a defined heatsink temperature.
The trip and reset points are different based on the
frequency converter power size.
Troubleshooting
Check for the following conditions
•
Ambient temperature too high
•
Motor cable too long
•
Incorrect airflow clearance above and below the
frequency converter
•
Blocked airflow around the frequency converter
•
Damaged heatsink fan
•
Dirty heatsink
This alarm is based on the temperature measured by the
heatsink sensor mounted inside the IGBT modules.
Troubleshooting
•
Check fan resistance
•
Check soft charge fuses
•
IGBT thermal sensor
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the
motor is missing.
