5.1.3 Remote Start/Stop Connections
Set the generator set master switch to the AUTO
position for remote operation. For remote starting and
stopping, use a three-wire start/stop switch connected
to the controller harness. To start the generator set,
open a contact between pins 6 (N) and 7 (STT) on the
controller harness connector and close a contact
between connector pins 5 (STP) and 6 (N) (see the
wiring diagram in Section 7). Close the contact between
pins 6 and 7 to stop the generator set.
5.1.4 Control Connections
Wiring harnesses connect the generator set control
board to the remote controls and the engine. The
generator set Operation Manual, TP-6119, shows the
engine, sensing, and controller wiring harnesses. The
wiring diagram in Section 7 shows the harness
connections. Figure 5-2 defines the abbreviations used
in the wiring diagram.
5.1.5 Resetting the Controller
Move the generator set master switch to the STOP
position and then release it to reset the controller. Reset
the controller after applying power for the first time or to
clear a fault condition. See Section 5.1.6 for more
information about faults.
Note: If the power to the controller has been
disconnected and reconnected, the controller will
require resetting.
