Winter-Fronts; Genset-Engine Starting; Starting Above 0°C (32°F) - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Winter-fronts

The genset enclosure can be fitted with Winter-fronts, contact Vanguard Equipment, Inc.
Winter-fronts can be used on the genset enclosure to reduce air flow through the radiator core. This can reduce the time
required to warm the engine and help maintain the engine coolant temperature. The engine coolant temperature
specifications are in the Maintenance Specification section of the CUMMINS® Operation and Maintenance Manual QSB4.5
and QSB6.7 Engine (Bulletin 4021531); see the appendices at the end of the Weld-Deck Operation and Maintenance
Manual, Weld-Deck welding package CPW 125-4-S2-4.
Adjust the Winter-fronts to maintain the engine coolant temperature above the CUMMINS® Minimum Recommended
Operating Temperature of 71ºC (160ºF); do not exceed the maximum operating temperature. Note: The genset automatically
shuts down if the engine coolant exceeds 100ºC (210ºF).

Genset-Engine Starting

Starting Above 0°C (32°F)
1. For additional steps and procedures for starting in temperatures below 0°C (32°F , refer to the Cold Weather Starting
Below 0°C (32°F) with Ether Starting section in this manual.
2. To stop the Genset, once it has been started, turn the Stop/Run/Start switch(1) to the stop position ().If any type of
emergency condition exists, use the RED emergency stop button (2) to IMMEDIATELY trip the main breaker to cut the
genset electrical power and to stop the genset.
3. Ensure that all of the pre-start-up checks in the Before Starting
Genset-Engine section of this manual have been made.
4. Ensure that the main service doors on genset are closed.
5. With the Rated/Idle switch (3) is at idle () move the genset
Stop/Run/Start switch (1) to start (). Release the Stop/Run/Start
switch after the engine starts. Note: Return the Stop/Run/Start switch
to stop () after cranking the engine for 15 seconds, and then retry
starting. Note: After every 30 seconds of engine cranking, allow the
starter-motor to cool for two minutes. Note: The genset engine will
automatically shutdown if the oil pressure drops below 138 kPa (20
psi).
6. If the engine does not start after three attempts, check the fuel
supply system. Absence of blue or white exhaust smoke during
3 1
cranking indicates no fuel is being delivered.
7. Once the engine starts, observe the oil pressure at idle. The oil
pressure should stabilize at approximately 10 psi (69 kPa).
2
Idle the engine three to five minutes before switching the Rated/Idle
switch (3) to rated ().Note: Do not operate the engine at idle for long
periods with the engine coolant temperature below the Minimum
Recommended Operating Temperature of 71ºC (160ºF), refer to
037-05-63-316A
CUMMINS® Operation and Maintenance Manual QSB4.5 and
QSB6.7 Engine (Bulletin 4021531); see the appendices at the end of
this manual.

8. Observe the oil pressure at Rated speed. The oil pressure should stabilize between approximately 40 to 60 psi (276 to
414 kPa).
9. Observe the coolant temperature to ensure that it is not too high. Note: The Genset will automatically shutdown if the
coolant temperature reaches 100 ºC (210 ºF).
