DIAGNOSTIC LED = Solid Red
SE-330HV processor failed to start. Cycle supply. If problem
persists, consult Littelfuse Startco. K1: De-energized.
Pressing RESET does not clear trips.
Trip condition is still present. Locate and correct.
The RESET button is disabled if remote-reset terminals 15 and 16
are connected. Replace shorted remote-reset switch or issue Reset
command from the communications network.
UNIT HEALTHY relay K4 momentarily
changes state.
Occurs when processor is reset.
No analog-output current.
The output at terminals 19 and 20 requires a voltage source. See
Fig. 2 for analog-output connections. See Section 9.3 for the
analog-output tests.
