Standard Faults - Baldor GLC30 Installation & Operating Manual

No Load Test
To allow a timed No Load Test of the engine/generator set while using the AMF control
application, a digital input contact from an external timer must be programmed for NO LOAD Test
The sequence of operation for a No Load Test condition is as follows:

Standard Faults

When a fault occurs, information about the fault is displayed. The engine controller has many
analog and digital inputs for monitoring and control operations. Three types of faults are used:
Figure 4-3 shows how the controller inputs and outputs are organized.
A description of each is provided.
MN2408
1. With the utility supply normal and the generator stopped, a no load test sequence may
be initiated by closing an external exercise timer contact to the programmed digital
input for No Load Test.
2. After the external exercise timer contact closes, the engine will start and come–up to
normal operating speed and voltage. The controller will issue an alarm of a No Load
Test condition. The connected transfer switch will remain on the utility and the
generator will not transfer on load. Note: should the utility supply fail, the generator will
automatically transfer on load.
3. The engine will continue to run as long as the external exercise timer contact remains
closed.
4. After the external exercise timer contact opens, the engine will continue to run for its
cool down time as programmed, then it will automatically stop.
1. Internal Faults are derived from a combination of digital and analog inputs.
2. Digital Input Faults are initiated from external contact inputs.
3. Analog Input Faults are initiated from external analog signal inputs.
