CHAPTER 7: MAINTENANCE, REPAIR, and WARRANTY
7.2.6 Over Voltage Fault:
When the DC Buss voltage reaches 250VDC, the Run LED will turn off, the
Overvoltage LED will turn on and a Fault Output is generated, and the amplifier is
inhibited. NOTE: This is a latched condition.
The following is a list of possible causes:
•
Main Buss line voltage is too high.
•
Decelerating a large inertial load. When decelerating, a DC motor acts as a
generator. If the inertial load is large, the generated voltage can pump up the
DC-Buss. If this fault occurs, you may need a Regen Clamp. Consult Glentek.
7.2.7 Resetting A Fault:
The fault latch may be reset by pushing the Reset button, activating the Reset input
J1-12 or by removing power and allowing the filter capacitor(s) to discharge. Note that
the fault latch will not reset unless the fault has been cleared.
7.3 Amplifier Failure:
If an amplifier should fail, that is, if it should cease to operate with no apparent fault, the
drawings in appendix will enable a skilled technician to trouble shoot an amplifier to even
lower levels.
7.4 Factory Repair:
Should it become necessary to return an amplifier to Glentek for repair, please follow the
procedure described below:
1. Reassemble the unit, if necessary, making certain that all the hardware is in place.
2. Tag the unit with the following information:
A. Serial number and model number.
B. Company name, phone number, and representative returning the unit.
C. A brief notation explaining the malfunction.
D. Date the unit is being returned.
3. Repackage the unit with the same care and fashion in which it was received. Label
the container with the appropriate stickers (e.g: FRAGILE: HANDLE WITH CARE).
4. Contact a Glentek representative, confirm that the unit is being returned to the factory
and obtain an RMA (Return Material Authorization) number. The RMA number must
accompany the unit upon return to Glentek.
5. Return the unit by the best means possible. The method of freight chosen will
directly affect the timeliness of its return.
Glentek also offers a one day repair service in the unlikely event that your system is down
and you do not have a replacement amplifier module.
