This is a fringe case that require attention. The OVP cannot be triggered if LIST:DWELl time is below ~3 ms (1 ms is set into example that follows). To reproduce this issue, connect load (e.g. 3R3) and execute the following code:
ABORt
VOLT 20
VOLT:PROT:LEV 20
VOLT:PROT:DEL 0
VOLT:PROT:STAT ON
LIST:COUNt INF
VOLTage:MODE LIST
CURRent:MODE FIX
CURR 0.5
LIST:VOLTage:LEVel 15, 25
LIST:DWELl 0.001
TRIGger:SEQuence:IMMediate
With connected load channel will be in CC mode, and when disconnected the OVP should tripped (set to 20V) but that is not going to happen.

Channel's output values that is included into list (i.e. VOLTage:MODE LIST
and/or CURRent:MODE LIST
) should be disabled for further changes locally and remotely when LIST is active. That has to be restored when LIST execution is interrupted.
from psu-firmware.
If LIST are active on both channel touchscreen is not responsive.
from psu-firmware.
Use OFF feature on local display as ABORt command for stopping triggered LIST. When change from OFF to ON check VOLTage and CURRent MODE and open pop-up menu with the following options:
- Run LIST
- Disable LIST
