Low mA
A Low mA fault occurs when the output current is below the current
reference set value by 18%.
This fault will produce the following results:
Light the Under Current (UC) LED
Respond to a Report Fault Command with Fault #004
This is not a latched fault and will not shutdown the unit
This fault will remain active for as long as the output current is below the
reference set value by >18%
Low kV
The fault occurs when the output voltage is below the voltage reference
set value by 10%.
This fault will produce the following results:
Light the Under Voltage (UV) LED
Respond to a Report Fault Command with Fault #005
Shutdown the unit
Change the status of pin 7 of the analog interface
to ‘Active low’
This is a latched fault
High kV
There are two High kV conditions:
a) When the output voltage exceeds 10% of max rated voltage
b) When the output voltage exceeds the reference set value by 10%
This fault will produce the following results:
Light the Over Voltage (OV) LED
Respond to a Report Fault Command with Fault #006
Shutdown the unit
Change the status of pin 7 of the analog interface
to ‘Active low’.
This is a latched fault.
Watchdog
The fault occurs when the Watchdog timer expires.
This fault will produce the following results:
Respond to a Report Fault Command with Fault #007
Shutdown the unit
Change the status of pin 7 of the analog interface
to ‘Active low’.
This is a latched fault.
