A Siemens Micromaster converts direct current to alternating current.
A Siemens Micromaster is a line of frequency inverters that converts direct current (DC) to alternating current (AC) to be used as power sources for batteries, solar panels and fuel cells. It also works as a form of power generator, supplying power to uninterruptible power supply (UPS) devices, which work for a period of time even when their power source does not. There are times when the Siemens Micromaster fails to work. You can troubleshoot your Siemens Micromaster to get it up and running again. Does this Spark an idea?
Instructions
1. The status display panel shows error messages. It has both a green and a yellow light next to it, and the number displayed on the panel correlates with what the green and yellow lights are doing. For example, if the green LED (light emitting diode) is flashing "R1," the yellow LED is flashing "R1" and the display panel shows "9," the Micromaster is at the current limit and should be turned down. If the green LED is flashing "R2," the yellow LED is flashing "R1" and the display panel shows "12," the inverter is not in a ready state. Verify that all connections are attached properly and restart the inverter. Check the owner's manual for a complete list of error messages.
2. The motor fails to start. When the "On" switch is flipped, the motor should start. If it does not, check to make sure that the display panel shows "P0010 = 0." Verify that a valid "On" signal has been given. Check that P0700 = 2 (digital input control) or P0700 = 1 (for basic operator panel) is set. Then check that the setpoint is present -- 0 to 10 volts on terminal 3 -- or that the setpoint has been changed to the proper parameter, depending on the source. You should have access to a parameter list for verification. If the motor still fails to run, set P0010 = 30, then P0970 =1 and press "P" to reset the inverter back to factory default specifications. Use a switch between terminals 5 and 8 on the control panel. The drive should run according to the current defined setpoint.
3. A fault message is displayed. There are a number of fault messages that could show on the status display panel. For example, if the inverter is running overcurrent, "F0001" will display. In that case, verify that the motor power is corresponding to the inverter power, that the cable lengths are correct, that there are no short-circuits or earth faults and that the motor is not obstructed or overloaded. To correct this, increase the ramp time and lower the boost level.
4. The motor is overheating. If the motor is running above normal operating temperature, "F0011" will show on the status display panel. To correct that, you must verify that the load duty cycle is correct, that the motor's nominal overtemperatures (P0626-P0628) are correct and that the motor's warning level temperature (P0604) matches.
