engaged. If it is not rotating, there may be a problem in the motor, or the motor-
to-generator linkage.

g. The pump is faulty. If no faults are found in steps a. through g., the problem is

likely to be a non-functional pump. Contact Smart Power

Output voltage exceeds 260 volts or falls below 220 volts AC on a 240 volt
line:

a. Verify that the hydraulic system is not overheating by viewing the temperature

as displayed by the Command & Control Center. The temperature should not
exceed 175° F. If the temperature is greater than 175° F, follow instructions for
system overheating (see hydraulic problems).


b. The hydraulic pump speed may be too low. Verify that the hydraulic pump

speed is in the required range (see Table 1). Pump speed can be calculated by
multiplying the engine RPM by the PTO ratio. Adjust the engine speed or PTO
ratio if necessary.


c. The generator speed may be incorrect. The generator output should be

between 59-61 Hz. If it is not, contact Smart Power
