5 SCPI Programming Reference
All conditions that generate the fault must be removed before the latched status can be cleared.
l
The output is restored to the state it was in before the fault condition occurred.
If a protection shutdown occurs during an output list, the list continues running even though the
l
output is disabled. When the protection status is cleared and the output becomes enabled again,
the output will be set to the values of the step that the list is presently at.
OUTPut:PROTection:TEMPerature:MARGin?
Returns the minimum difference between the internal temperature sensors and the over-
temperature trip level. The margin is returned in degrees Celsius.
Parameter
(none)
Returns the temperature margin: OUTP:PROT:TEMP:MARG?
OUTPut:PROTection:WDOG[:STATe] 0|OFF|1|ON
OUTPut:PROTection:WDOG[:STATe]?
Enables or disables the I/O watchdog timer. When enabled, the output will be disabled if there is no
I/O activity on any remote interface within the time period specified by the
OUTPut:PROTection:WDOG:DELay command. The output is latched off but the programmed output
state is not changed.
Parameter
0|OFF|1|ON, *RST OFF
Enables the watchdog timer protection: OUTP:PROT:WDOG ON
OUTPut:PROTection:WDOG:DELay <value>|MIN|MAX
OUTPut:PROTection:WDOG:DELay? [MIN|MAX]
Sets the watchdog delay time. When the watchdog timer is enabled, the output is disabled if there is
no SCPI I/O activity on any remote interface (USB, LAN, GPIB) within the delay time. The watchdog
timer function is NOT reset by activity on the front panel - the output will still shut down after the time
period has elapsed. Programmed values can range from 1 to 3600 seconds in 1 second increments.
Parameter
0 - 3600, *RST 60 seconds
Sets a watchdog delay for 600 seconds: OUTP:PROT:WDOG:DEL 600
