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

2.
Output voltage exceeds 260 volts or falls below 220 volts AC on a 240 volt line
for 60 Hz systems OR output voltage exceeds 240 volts or falls below 200
volts AC on a 220 volt line for 50 Hz system:
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 engine speed is in
the required range (see Table 1). Adjust the engine speed if necessary.
c. The generator speed may be incorrect. The generator output should be
between 59-61 Hz for 60 Hz systems or 49-52 Hz for 50 Hz system. 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

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
