Mobile Diesel Systems OWNERS MANUAL MDS45 INSTALLATION AND OPERATION MANUAL 60706-154
Read and understand all instructions in the manual before starting and operating the generator set. TABLE OF CONTENTS USING THIS MANUAL Congratulations on your choice of a Winco generator set. You have selected a high-quality, precision-engineered generator set designed and tested to give you years of satisfactory portable service. To get the best performance from your new engine generator set, it is important that you carefully read and follow the operating instructions in this manual.
GUIDE TO PRODUCT SAFETY This engine generator set has been designed and manufactured to insure your personal safety. Improper use can result in potential deadly hazards, from electrical shock, exhaust gas asphyxiation, or fire. Please read all safety instructions carefully before installation or use. Keep these instructions handy for future reference. Take special note and follow all warnings on the unit and in the manuals.
SPECIFICATIONS UNPACKING GENERATOR SPECIFICATIONS When receiving the unit, be sure to inspect it carefully for freight loss or damage. Check the nameplate to be sure it is what you ordered (proper kW, voltage, fuel, etc.). If you have questions, contact your local authorized dealer. If you see evidence of loss or damage at the time of delivery, have the driver sign and describe the loss or damage in the “memo of loss or damage” section on the freight bill.
COOLANT REQUIREMENTS The cooling system of this engine has been filled at the factory with a 50% water and 50% ethylene-glycol antifreeze and the proper amount of supplemental coolant additives. This mixture provides protection to -37 degrees F. WARNING - POTENTIAL BATTERY EXPLOSION When replenishing coolant or changing coolant refer to your Cummins engine manual for the proper type and mixture of water, antifreeze and supplemental coolant additives.
starter is engaged. The engine control module in the control panel will disengage the starter when the unit starts and engage the engine monitoring sensors. b. Field circuit breaker (FCB) (9)- Protects voltage regulator and exciter field in the event of a load short circuit or equipment malfunction. c. “AUTO” - This switch position is used when the MDS45 is used in a standby mode. With the switch in this position a remote contact (i.e.
a. Low Oil Pressure Lamp (LOP) - Indicates that the unit did not maintain a minimum oil pressure of 15 psi. C. FULL POWER LOAD CONNECTIONS and BREAKERS b. High Water Temperature Lamp (HWT) - Indicates the coolant temperature in the engine exceeded upper coolant temperature limits. This Mobile Diesel Power System is equipped with both high voltage (480) and low voltage (208/240) main line breakers. The breakers are interlocked with a lockable bar to insure that only one breaker can be turned on at a time.
b. High water temperature shutdown -(HWT)- The engine coolant sensor temperature monitoring begins immediately with the start signal. If water temperature is excessive at time of start, (i.e. heat soak after shutdown), the unit is still permitted to start. The ‘HWT’ condition is permitted to exist for up to 60 seconds after the unit initially starts before a shutdown WITH ALARM occurs.
Upon detection of over excitation and the resulting field voltage shutdown, the regulator will not reset or return to an operational condition until the generator output voltage drops to less than 6 VAC for ten seconds (minimum). TO ACCOMPLISH THIS ON A MOBILE DIESEL GENERATOR SET THE FIELD CIRCUIT BREAKER MUST BE TURNED OFF FOR TEN SECONDS. 3. 277/480 Three Phase (High/Series WYE configuration) This configuration will produce the following line-toline and line-to-neutral outputs.
4. After the engine is running at proper speed, adjust the voltage to the desired level using the external voltage rheostat. 5. Turn on the proper main line breaker (either high or low voltage) and padlock the lock bar to prevent the incorrect breaker from being turned on. 10. For isolated neutral operation remove the jumper wire between the ground lug and neutral connection block. 11. Ground the Mobile Diesel Generator set using an 8 ft copper ground rod or other approved grounding system.
2. FULL POWER LOAD CONNECTION TERMINAL BLOCK - For remote connections and connecting load distribution boxes, heavy duty terminal blocks have been provided. These terminal blocks are located on the rear of the unit just below the main line circuit breakers. The neutral and ground are connected together at this panel. For use with an isolated neutral, remove the jumper strap between the neutral connection block and the ground lug.
