LARM
All DC power circuits managed by the eF-785 are protected against over-
current events by front panel fuses or circuit breakers. This includes not
only DC Motor Supply power and 24VDC sensor/actuator power, but
also the 24VDC internally supplied safety power and 40VDC
ControlPoint™ network hub power. Each of these seven circuits has it’s
own “fuse-blown” LED indicator. In addition to the open/tripped
indicator LEDs on each circuit, if any of these devices should open or
trip, an annunciator will emit a high-pitched continuous tone to alert the
operator to the over-current event. Unless power is removed from the
unit, the tone will sound until the fuse is replaced.

ROTECTION
The AC voltage available at the Host Power connectors JA and JB, the
24VDC Supplies connector (J5, pins 6 and 9), and the 40VDC net
power’s AC side are all protected by the rear panel fuses F1 and F2. The
fuses used in F1 and F2 can not be rated for more than 8 Amps. A
suggested time-delay fuse is Bussmann/MDA-8.
