Test Auxiliary Shutdown Switch

Operation

The generator is equipped with an independent means of

shutting down prime mover (engine) for use in emer-

gency situations. The shutdown mechanism, when acti-

vated, requires a mechanical reset.

See Figure 3-8. Generators 15 kW and larger are

equipped with two auxiliary shutdown switches. One aux-

iliary shutdown switch (A) is located on the generator roof

above and to the right of the viewing window. The second

auxiliary shutdown switch (B) is inside the control panel

enclosure.

Figure 3-8. Auxiliary Shutdown Switches

Test auxiliary shutdown switches after installation to ver-

ify correct operation.

1. Verify auxiliary shutdown switches are ON (I).

2. Press MANUAL key on control panel keypad to

start engine.

3. With engine running, set one auxiliary shutdown

switch to OFF (O). Engine should shut down imme-

diately.

• If engine stops, set auxiliary shutdown switch to

ON (I), clear alarm on controller, and restart engine

to verify generator is operating normally. After veri-

fying normal operation of first auxiliary switch, ver-

ify operation of second auxiliary switch.

• If engine does not stop, auxiliary shutdown

switch is not functioning correctly. Contact an

IASD.

NOTE: Auxiliary shutdown switches are not intended to

be a primary means to shut down generator under nor-

mal operating conditions. Accidental activation of an aux-

iliary shutdown switch will prevent generator from

operating during a power outage.
