IGBT TRIP ALARM
The current drawn by the load exceeds the
capacity of VASCO. VASCO is still able to
continue to power the load for 10 minutes with
an output current of 101% of nominal and for 1
minute with an output current of 110% of
nominal
–
Increase the ramp-up time
–
Make sure that the load current is at least 10% below
the VASCO nominal current
–
Check the voltage drop along the supply cable to the
motor
OVER VOLTAGE
Supply voltage too high
Check possible causes of over voltage
UNDER VOLTAGE
Supply voltage too low
Check possible causes of under voltage
ADDRESS ERROR
Same address as other VASCOs in the group
The address of each VASCO needs to be different.
ALARM SLAVE XX
Slave XX error detected by master
Check the status of the slave.
SENSOR FAULT
Sensor error
–
Check the pressure transducer
–
Check the wiring of the transducer
NO LOAD
No load
Check is load is properly connected to VASCO terminals
MAX. VALUE
ALARM
Measured value has reached the maximum
value accepted by the system.
–
Check possible causes of reaching maximum value
–
Check the max. alarm value setting
KEYBOARD FAULT
A button on the keyboard has been pressed for
more than 150 seconds.
–
Make sure buttons are not depressed.
–
If problem persists, call Dutypoint Technical Service
on 01452 300590.
ACTIVE DIG.IN.X
Digital input X opened/closed
Check the input digital configuration (IN/OUT parameters
