Section 1 — General Information

Guardian Liquid-cooled 25 kW Generator

Figure 1.6 - Low Coolant Level Sensor ‹ 1.8.2 INSPECTION

‹1.7.4 OVERSPEED SHUTDOWN

Should AC frequency exceed about 72 Hz, circuit board action will automatically shutdown the engine.

‹1.7.5 OVERCRANK SHUTDOWN

The engine control board uses a cyclic cranking process when attempting to start the engine. The first crank cycle is a 15-second crank followed by a seven- second rest. This is followed by five more crank cycles each with a seven second crank followed by a seven-second rest.

If the engine fails to start after all six attempts, the start attempt is stopped and the overcrank LED turns on.

‹1.7.6 LOW BATTERY

The engine control board continually monitors the battery voltage and turns on the low battery LED if the battery voltage falls below 12 VDC for one minute. Low battery voltage is a non-latching alarm, which will automatically clear if the battery voltage rises above 12 VDC.

‹1.7.7 15A DC FUSE

This fuse is located inside the control panel. It pro- tects the panel wiring and components from damag- ing overload. The unit will not start or crank if the fuse is blown. Replace the fuse with one of the same size, type, and rating.

1.8UNPACKING

‹1.8.1 UNPACKING PRECAUTIONS

Handle shipping cartons and crates with care. Use care to avoid damage from dropping, bumping, colli- sion, etc. Store and unpack cartons with the proper side up, as noted on the shipping carton.

Upon delivery, carefully inspect the generator for any damage that may have occurred during shipment. If loss or damage is noted at the time of delivery, have the person(s) making delivery note all damage on the freight bill or affix their signature under the consign- or’s memo of loss or damage.

1.9LIFTING THE GENERATOR

When lifting or hoisting equipment is used, be

!careful not to touch overhead power lines. The generators weight of more than 900 pounds requires proper tools, equipment, and qualified personnel to be used in all phases of handling and unpacking.
