5. Startup and Configuration2-2017

NOTICE

When the generator set is operating in the Remote Start mode, removing

the Remote Start command does not shut off the engine if the load is

more than 10%, the cooldown timer is set to zero, and the control is

configured for a single unit (not in parallel). The generator set continues

to operate until it runs out of fuel, the E-stop button is used, or the load

is removed.

2. To disable Auto mode, change to Manual or Off mode.

Cold Starting with Loads

NOTICE

Make sure that all pre-start checks are carried out before starting the

generator set. Do not attempt to start the generator set until it is safe to do

so. Warn all others in the vicinity that the generator set is about to start.

Use a coolant heater if a separate source of power is available. The optional heater

available from Cummins Power Generation will help provide reliable starting under

adverse weather conditions. Be sure the voltage of the separate power source is

correct for the heater element rating.

Cummins Power Generation recommends equipping standby generator sets (life

safety systems) with engine water jacket coolant heaters to maintain the coolant at

a minimum of 32 °C (90 °F) and, for most applications, accept the emergency load

in ten seconds or less. Although most Cummins Power Generation generator sets

will start in temperatures down to -32 °C (-25 °F) when equipped with engine water

jacket coolant heaters, it might take more than ten seconds to warm the engine up

before a load can be applied when ambient temperatures are below 4 °C (40 °F).

To advise the Operator of a possible delay in accepting the load, the Low Coolant

Temp (code 1435) message, in conjunction with illumination of the Warning LED,

is provided. The engine cold sensing logic initiates a warning when the engine water

jacket coolant temperature falls below 21 °C (70 °F). In applications where the

ambient temperature falls below 4 °C (40 °F), a cold engine may be indicated even

though the coolant heaters are connected and functioning correctly. Under these

conditions, although the generator set may start, it may not be able to accept load

within ten seconds. When this condition occurs, check the coolant heaters for

correct operation. If the coolant heaters are operating correctly, other precautions

may be necessary to warm the engine before applying a load.

Checking Coolant Heater Operation

WARNING

Hot Surfaces

Contact with the hot surfaces can cause severe burns.

Avoid contact with hot parts. Allow hot parts to completely cool.
