OCP Delay
For the E36231A and E36232A models, OCP delay is only used when the instrument is in general mode. OCP
limit is used instead when the instrument is in persona mode.
The power supply may momentarily cross into CC mode when it is turned on, when an output value is programmed,
or when the output load is connected. In most cases these temporary conditions would not be considered an over-
current protection fault, and having an OCP condition disables the output when the CC status bit is set would be a
nuisance. Specifying an OCP delay will ignore the CC status bit during the specified delay period.
To set the over-current protection delay, enter the delay value in the OC Protection Delay field. The delay can be
programmed from 0 to 3600 seconds.
OCP Delay Start
Specifying an OCP Delay Start lets the OCP circuit ignore the CC status bit during the specified delay period. Once
the OCP delay time has expired and if the CC mode persists, the output will shut down.
You can specify the OCP delay start timer through:
– CC Transition: Delay timer starts at any transition of the output into CC mode. Press OCP Start CC .
– Setting Change: Delay timer starts at the end of a settings change in voltage, current, or output state. Press OCP
Start Set
.
Clears and OVP and OCP Event
To clear the protection function, first remove that condition that caused the protection fault.
Press
Protection Clear
to clear the protection function and returns the output to its previous operating state.
From the remote interface:
To set the over-voltage protection for output 1 to the maximum limit:
VOLT:PROT MAX (@1)
To enable the over-current protection for output 1 and 2:
CURR:PROT:STAT ON (@1,2)
To set the over-current protection delay time for output 1 at 3 seconds:
CURR:PROT:DEL 3 (@1)
To set the over-current protection delay timer start for output 1 to CC transition:
CURR:PROT:DEL:STAR CCTR (@1)
To clear protection for output 1:
OUTP:PROT:CLE (@1)
