RED-E
FAQ
The car doors work properly when supplied by mains power, while they work in the opposite way when supplied by RED-E:
Exchange MP1 with MP2 and exchange MP1Q with MP2Q
When the emergency operation starts, the over current protection of the auxiliary inverter trips (Led A flashes):
Ceck the connections between RED-E and control panel and try to disconnect all the circuits and connect them again one at a time, when you find out the connection which makes the auxiliary inverter to trip, check carefully the corresponding circuit.
When RED-E drives the motor, the over current protection of the power inverter trips (Led B flashes):
Check that RED-E is compatible with motor power which has to be controlled. Check that the terminals U, V e W are connected to the motor high speed winding only.
Decrease the power inverter output voltage (turning the trimmer V anti-clockwise) and increase the output frequency (turning the trimmer F clockwise).
When RED-E drives the motor, the Leds UP, VP, WP flashes, but the motor doesn’t rotate:
Increase the power inverter output voltage, turning the trimmer V clockwise.
Decrease the power inverter output frequency, turning the trimmer F anti-clockwise.
The run direction selection is wrong, for example RED-E chooses the unfavourable direction and it is not able to drive the motor:
Try to decrease the power inverter output frequency, turning the trimmer F anti-clockwise.
The emergency run is carried on with “jogging” operation:
This is not a faulty operation, this type of operation is done for safety reason, in order to avoid that in lifts with highly reversible gears the car can take dangerous speed without any control.
When the car reaches the floor, it doesn’t stop at the correct level:
if the car oversteps the floor level, decrease the stop delay, turning anti-clockwise the trimmer R.
if the car stops before reaching the floor level, increase the stop delay, turning clockwise the trimmer R.
