11.5.4. Set Foldback Protection
This command enables or disables the foldback protection. When the FB protection is enabled, if the power
supply goes into constant-current (CC) mode for about a ½ second, then the output will turn off, the front
panel will show "Fb" and the Questionable Condition register bit 3 will be set high.
This protection is normally used to prevent a hazard condition if the output load goes into a short-circuit.
For applications where the power supply is normally operating in CC mode, such as driving electro-magnets,
the FB protection cannot be used.
The FB setting is seen on the supply's front panel FOLD LED. A foldback fault is cleared by turning the
power supply output on again.

11.5.5. Read Foldback Tripped

11.6. LAN Specific Commands

11.6.1. Blinking the Identify LED
When communicating to a stack of Genesys™ power supplies, it may be difficult to know which supply is
selected for communicating. The LAN computer may send a command to cause the selected supply's front
panel displays to blink on and off. Also, the LAN LED on the rear panel will blink. In a multi-drop chain of
supplies (see section 12), only the LAN supply will blink.
If blinking is turned on, then it may be turned off by sending the OFF command or by changing any front
panel control.
