Sequence

(J3d)

This mode will performs the function of sequencing the electrical loads on
and off.

Automatic Load Reset

(J2b)

Any load which has been shed will automatically be controlled off for a mini-
mum of five minutes, regardless of the state of the electrical system. After the
electrical system becomes stable, the loads will be controlled back on by the
system. Any shed load can be turned on immediately by performing a manual
load reset (see next section).

Manual Load Reset

(J2a)

When this mode is enabled, any load which has been shed will remain off
until the system manager is manually reset.

Manually Resetting the System

There are two levels of manual reset.

LOAD

RESET

and

FULL

RESET

.

Load Reset:

The shed loads are manually reset by toggling the master switch

off and then on again within two (2) seconds. When a load reset is per-
formed, all loads which are currently shed of will be sequenced on. The
system manager will refrain from shedding any load for fifteen minutes. After
fifteen minutes, normal operation of the system manager will resume.

Full Reset:

Full system reset will occur when the master switch is turned off for

at least two seconds. After full reset, the loads will be sequentially turned off
and the system will resume normal operation when the master switch is toggled
to the on position.

Over-Voltage Indicator

(J4d)

The system manager continually monitors the system voltage and will acti-
vate an output when it detects that the constant system voltage has increased
above 14.5 volts. As in all modes, the system will not react to the spurious
voltage transients which may exist in the electrical system as loads and de-
vices are cycled.

Fast Idle Control

(J4c)

The system manager is capable of becoming a part of a system which con-
trols a fast idle device. The fast idle output will activate whenever the system
voltage is low. The output will deactivate if the system manager is reset or the
voltage becomes good.
This circuit must only be utilized when the appropriate interlocks are present.
