CONNECTION INFORMATION
Your new Baldor Generator has all interconnecting wiring terminated at a junction box. All wiring will be
clearly labeled as being load; remote start contacts and AC input terminals and are to be connected as
described below.
Load –These connections are rated and sized according to the KW of the generator. Proper lead
wire from these points to the automatic transfer switch (or load switching device) is mandatory.
See enclosed transfer switch information for corresponding generator input terminals.
Remote Start Contacts –This two–wire connection, once connected to an appropriate switch,
will start the generator and perform as described in the remote start/stop literature. These
contacts are connected to the “Engine Start Contacts”of the automatic transfer switch.
A Two Pole normally open, closed to operate switch may also be used to start the generator.
AC Input –These connections are for units with float type battery chargers or engine block
heater combinations. A Constant supply of 120 volts AC (or as specified) is needed at these
terminals to power these devices.
NOTE: Power is not required when the unit is in operation. Internal battery charging and radiant heat
during operation eliminate the need for these devices.
NOTE: It is recommended that units utilizing an automatic transfer switch with adjustable time delays
have the initial adjustments made prior to start–up.
Factory recommendations are; allow a 2 second delay on start–up, 15–second delay on emergency to
normal.

CONTROL PANEL OPERATION
AND FUNCTION
A. MASTER CONTROL SWITCH –This switch controls the starting and stopping of the engine via
the engine control logic circuitry.
With this switch in the “Manual”mode, the engine will start and run immediately after a
10 –20 second time delay.
CAUTION: Please note that once the engine has been told to start, the gen set
should be treated as though it is operational, even though the start
delay has not yet allowed the engine to crank.
With this switch in the “Automatic”mode, the engine can be started and stopped from a remote
contact. (Standard switch, transfer switch, etc.) There is a time delay, to cool down, of 60–90
seconds when the unit is shut down from the remote contacts while the Master Control Switch is in
the “Automatic Mode.
With this switch in the “Off”position, the engine will immediately stop. The position must also be
utilized to clear fault shut–down conditions.
B. PANEL LIGHTS –By turning on the panel light switch, the panel lights will be energized and will
illuminate the control panel. The fuse next to the switch is to protect this circuit from damage due to
excessive current.
C. FIELD AND CONTROLLER FUSES –These fuses protect the internal workings of the generator
set.
D. GAUGES –These gauges monitor some of the more critical operating parameters of the engine as
well as the run time of the generator set.
The Voltmeter displays the charging rate that is currently being produced by the engine’s alternator to
facilitate the charging of the battery. This gauge should normally be above 12.5V whenever the unit is
running. If you ever notice the gauge is reading below 12V while the engine is running please contact
the service department at Baldor Generators.
The Temperature Gauge monitors and displays the operating temperature of the engines coolant. The
point at which a fault shut–down will occur is approximately 230°F.
The Oil Pressure Gauge displays and monitors the current operating pressure of the engine’s oil
system. The trip point at which a fault shutdown will occur is approximately 15 PSI or below.
Fuel level is checked by the owner or is usually a separately supplied fuel tank.
The Hour Meter accumulates and displays the total running time of the generator set.

12
E. VOLTAGE ADJUST –The rheostat allows the user to “fine tune”the generator set’s voltage
output. It is normally used to adjust output voltage after switching the output of the generator set to a
different voltage.
F. METERS –These meters monitor and display the current operating parameters of the generator set.
The Voltmeter monitors and displays the current operating AC output of the generator set.
The Hertz Meter monitors and displays the current operating frequency of the generator set.
The ammeter monitors and displays the amount of current that is being delivered by the generator set.
This meter works in conjunction with the Voltmeter Switch (Item G) in determining which output leg
to monitor.
G. AMMETER SWITCH –The switch allows the user to switch between L1, L2 and L3 to monitor the
current in each output leg of the generator.
H. PANEL LIGHT –By turning on the panel light switch, the panel lights (Not pictured on diagram)
will be energized and will illuminate the control panel.
I –SYSTEM FAULT INDICATORS –These lights will come on when a fault condition or a warning
condition develops.
The “Low Oil Pressure”light will come on when the engine’s oil pressure drops below 15 PSI. This
condition will trigger a fault shut–down and the unit will stop.
The “Over–crank”light will come on when the engine has failed to start after four attempted crank
cycles. Each crank cycle consists of a 12 second time period followed by a 12 second rest time
period.
The “Over–speed”light will come on when the engine’s operating speed rises above it’s normal
operating parameters. This condition will trigger a fault shut–down and the engine will stop.
High Temperature light will come on when the engine’s operating temperature exceeds the safety
set–point.

OPERATION –PRE–START PROCEDURE
1. Fill system fuel tank with clean, fresh diesel fuel.
CAUTION: Wipe up any and all fuel spillage.
2. Fill engine crankcase to full mark with clean, fresh lubricating oil per attached engine operating guide.
3. Radiator coolant should be checked at the beginning of each day and filled in compliance with the engine
manufacturer’s guidelines.
4. Secure the generator for operation.
Skid mounted –the power generating system should be mounted to a smooth,
hard surface suitable for supporting the system under all stress conditions.
Trailer mounted –block wheels to prevent accidental movement.
Adequate clearance must be provided for access doors to fully open.
NOTE: The generating system exhaust also exits radiator end. When
positioning a generator system ensure position does not cause a
concentration of toxic emissions.

15
OPERATION –STARTING
1. Conduct ‘Pre–start Procedures.
2. Switch the generator set to the applicable voltage setting.
3. Connect the load(s) to the circuit breaker.
WARNING: High voltage is present when the generator set is running.
4. Move the ‘Master Control Switch”to the appropriate position.
5. Adjust the voltage if necessary by turning the voltage adjustment knob located on the control panel.

16
OPERATION
The prime mover utilized in this power generating system is controlled via an engine control module.
Starting is accomplished by commanding the control to ”start”the engine. This command can be
given by a number of controls.
? The operator control mounted on the front panel.
? The remote controls via the transfer switch or remote start terminal closure.
Initially, the system may be started and operated by placing the operator control in the ”manual/run”
position. To cease operation, return the switch to the ”off”position.
NOTE: Clear unit of all loose objects and perform all ”pre–start”procedures before operating
generator system.
ENGINE CONTROL MODULE:
The engine control module (ECM) is a microprocessor–based module that monitors the control and
safety inputs and provides all the required START and STOP functions automatically.
The following front panel controls and instruments are wired into the microprocessor through the
ECM terminal blocks:
1. Run–Off–Auto Switch
a. * ”Run”–run position causes the generator set to start and run immediately.
b. * ”Auto”–auto position allows unit to be controlled via any remote single–pole ”dry”contact
(transfer switch, etc.). Contact closure causes the unit to start and run, while contact opening causes
unit to shut down after a preset cool down period.
c. ”Off”–unit operation is terminated.
* –units equipped with Isuzu engines may have a time delay glow plug cycle before starting.
2. Lamp Test
Push button energizes all alarm lights simultaneously. This feature is disabled with the
run–stop–auto switch in the ”stop”position, and has no other effect on unit operation.
SAFETY INPUTS
1. Low Oil Pressure Shutdown –(LOP)
Monitoring of oil pressure begins for a preset time after unit starts and remains in effect until
unit is shut down (except as noted in ”loss of frequency input”below). The LOP signal is derived
from an oil pressure switch gauge mounted on the control panel
2. High Temperature Shutdown –(HT)
The engine temperature monitoring begins immediately with the start signal. However, if engine
temperature is excessive prior to start (i.e., heat soak after shutdown), the unit is permitted to
start.
The high temperature condition is permitted to exist for up to 60 seconds after the unit is running
before shutdown when alarm occurs. If the excessive temperature condition is corrected within
that time period, the HT circuit reverts to normal monitoring. The HT signal is derived from a
monitoring device located on the prime mover.

17
3. Over–speed Adjustment –(OS) –Over Frequency
Over–speed protection is provided by a frequency sensing network within the controller. The trip
point of the frequency network is adjustable via a rheostat located on the top of the controller at
the right hand side. Clockwise (CW) rotation increases the trip frequency and, thereby, raises the
shutdown speed.
CRANKING CONTROL
1. Over–crank Protection
This feature provides a preset second crank cycle. Failure of the engine to start by the end of the
crank period results in an ”Over–crank”shutdown and alarm indication.
2. Cranking Disconnect Adjustment (CDS Adjustment)
The cranking disconnect signal is obtained by a frequency network within the controller. The trip
point of the frequency network is not adjustable.
LOSS OF FREQUENCY
Internal protection against loss of frequency input to the cranking disconnect circuit is programmed in
after the unit has started normally. In the event the frequency goes to zero (engine runs out of fuel,
frequency signal source fails, etc.) the LOP shutdown circuit is bypassed and a 12–second wait
period is initiated. If frequency returns within this time period, LOP monitoring resumes and operation
continues normally. If frequency has not returned at the end of this time period, the engine oil
pressure status is observed to determine whether the engine is actually running or stopped. If the
engine has stopped (i.e., air in fuel, etc.), the cranking cycle will begin in an effort to restart the
engine. If the engine has not stopped (loss of input signal, etc.), the unit is shutdown with an
”Over–crank”indication and alarm.
WARNING: Over–crank indication can mean a loss of crank–disconnect signal during the
previous run period. Attempting to restart the engine with no crank–disconnect signal can
destroy the starter motor, which can cause serious personal injury.
This is of particular note since the tendency is to pursue only cranking and start related faults. The
cranking disconnect signal source is a key component in this system and must be checked out
thoroughly whenever an ”Over–crank”shutdown occurs.
NOTE: The controller does not provide protection against loss of signal during start–up. A
shutdown with alarm, due to any of the above conditions, will prevent any subsequent
operation of the generator set. The run–stop–auto selector switch on the control panel
must be momentarily placed in the stop position to reset these functions.
CAUTION: If a dead battery is suspected, remove controller fuse, charge battery (or replace), and
then attempting starting. Damage to engine control may result from jump starting.
