These bits are reserved for future use.
• Bit 12 – Communication alarm
This alarm latch is set when the device (Modbus Master or Ethernet Master) who started the power
supply (sent enable start or enable restart commands) does not send any request for KEEPALIVE
ms.
• Bit 11 – Arcing alarm
This alarm latch is set when the power supply detects a arcing event.
• Bit 10 – Output over-current alarm
This alarm latch is set when the power supply detects a output over-current event. This alarm latch
is set only if switch SW1 mode is set to ON and the output current increases over
SW1_THRESHOLD.
• Bit 9 – Output over-voltage alarm
This alarm latch is set when the power supply detects a output voltage the 5% over the given set-
point.
• Bit 8 – Input voltage alarm
This alarm latch is set when the power supply detects an input over/under-voltage of 25% the rated
input voltage.
• Bit 7 – Over temperature alarm
This alarm latch is set when the power supply internal temperature increases over 80°C.
• Bit 6 – Interlock alarm
This alarm latch is set when interlock input signal is missing.
• Bit 5 – Safe alarm
This alarm latch is set when safe input signal is missing.
• Bit 4 – Global alarm
This flag is set when at least one alarm latch is set.
• Bit 3:2 – Output current gradient
This field has three valid value:
• 0 – current is holding (HOLD)
• 1 – current is rising (UP)
• 2 – current is falling (DOWN)
• Bit 1 – Need restart
This flag is set when the power supply detects three arcing event or three overcurrent event in less
than 45 seconds. When this flag is set there are two ways for starting again the power supply:
• by sending enable off command and then enable restart command.
• by sending enable restart command.
• Bit 0 – Enable
This flag shows the current power supply status, if set it means the power supply have been
started, if not set the power supply is stopped.

Bit 272:279 – Switches output status
• Bit 15:3 – Reserved bits
These bits are reserved for future use.
• Bit 2 – SW3 Output state
This flag shows output status of SW3 switch.
