Lan Specific Commands - TDK-Lambda GENESYS Series User Manual

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.
Syntax:
Parameter: 0 or OFF will turn the foldback protection OFF

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.
