h. 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
®
Systems at (231) 832-5525
for further instructions.
d. If the problem is not detected by performing steps a. through c., contact Smart
Power

Systems.
3.
Generator Noise:
Generator noise can be caused by defective generator bearings or a faulty
generator/hydraulic motor coupling.
a. Contact Smart Power
®
Systems if bearings need replacement.
b. Check the generator/hydraulic motor coupling and replace it if necessary.
If problems occur other than those listed call Smart Power
