4.8 Front Panel Lockout
The front panel lockout mode enables a user to disable the front panel controls when the unit is
being programmed exclusively through the J3 remote input connector. To activate the front
panel lockouts, push the front panel LOCAL/REMOTE switch to the REMOTE position with the
S1 rear panel Dip switch S1–8 in the down or closed position. Once the lock function has been
activated, it disables local control for all output control functions, except the AC power switch,
which remains under front panel control and lights the front panel LOCK LED.
4.9 Fault Alarm Signal
Active high state in converter indicates over temperature, over voltage protection (OVP), or
internal shutdown. The Fault signal is the summary of protection. Circuits return J3-6 (Status
Indicator Return). This terminal goes to low state when the converter is operating under normal
conditions.
