2.4.5 Shutdown Switch
The generator set may be equipped with a Shutdown
(Prime Mover) switch. See Figure 2-2 and Figure 1-2.
This switch, also referred to as the Engine Shutdown
switch, commands an immediate shutdown and
prevents an engine start if the switch is turned to the off
(open, O) position. When the shutdown switch is
activated, the controller display shows Emerg Stop
Shutdwn.
The switch is a mechanical, rocker-style switch. Press O
to prevent engine start during generator set service.
Press I to allow the engine to start and run.
See Figure 2-2 for switch connections.

2.4.6 Engine Start Crank Cycle
The controller attempts to start the generator set three
times (three starting attempts, 15 seconds crank and
15 seconds off). If the generator set does not start in
three attempts, the system shuts down on an overcrank
fault. See Section 2.6.
Cranking 1, 2, and 3 are displayed during the crank
cycle. Pressing the OFF button during the crank cycle
stops the cranking. No other buttons are acknowledged
during the crank cycle.
20 kW Models (RDC2.4 v1.4.4)
For RDC2.4 controllers with firmware version 1.4.4 or
later, the 20 kW models will perform two crank cycles
with 3 starting attempts during each cycle. The
controller attempts to start the generator set three times
(three starting attempts, 15 seconds crank and
15 seconds off). If the generator set does not start in
three attempts, the controller pauses for 45 seconds,
and then performs another set of 3 starting attempts. If
the generator set does not start during these crank
cycles, the system shuts down on an overcrank fault.
See Section 2.6.
