Therefore the semiconductors can only be damaged by short-circuit currents during ramp-up and ramp-down. Please note that the motor controller does not insulate the motor from the mains. Figure : Protection of the device when using fuses. Protection with semiconductor fuses is intended to protect the motor feeder and motor controller from damage due to short-circuit. Figure : Protection using a thermal-magnetic motor protection relay. The motor feeder is protected but damage to the motor controller is possible. When motor failure occurs, if part of the motor winding limits the fault current and the motor feeder is protected, this type of protection can be considered acceptable.

Ramp setting procedure Factory DEFAULT - Plug and Play The ramp selector is set to bargraph position, according to Table : "Level Parameters".The product will be shipped with this standard ramp setting. If this setting is considered suitable, no other settings are required. Level - FACTORY PRE- DEFINED RAP PARAE- TERS For this mode, the -phases L,L,L must be present but control, must not be present. In this level, the user may select from 0 predefined ramps by selecting one of the 0 bargraph positions:,,..9 or 0, according to Table : "Level Parameters". Position is the same as the factory DEFAULT described above. In each predefined ramp, the values for all parameters (ramp up, ramp down, initial torque, kickstart, ramp up shape and ramp down shape) are fixed by the factory against each bargraph LED position. Position 0 is factory set for "High Torque Load" (see Table ) but can be re-programmed according to Level instructions. The bargraph LED will remain ON at the selected position during operation as long as L,L,L are present, to show which ramp parameters are being used. To enter Level mode: Press SELECT once. One bargraph LED will start flashing at the position that has been previously programmed (position if the product is just out of the box). To select the factory predefined ramp: Use the UP and DOWN arrow buttons to move the flashing LED up or down on the bargraph. To save and exit Level mode: To fix the new settings, press SELECT. This stores the selected ramp position and causes the device to exit Level. The bargraph LED remains ON at the selected position during operation as long as L,L,L are present. (If no button is pressed for several seconds, the device goes out of this setting mode automatically and above steps must be repeated). Level - RAP CUSTOI- SATION In this level, a new combination of parameters settings (ramp up, ramp down, initial torque, kickstart, ramp up shape and ramp down shape) can be made that is not included in the pre-defined ramps of Level (In Level these settings have been fixed by the factory. See Table : Level Parameters).In Level, each parameter of "position 0" can be re-defined individually by first selecting the parameter and then setting the bargraph level in accordance with Table : "Level Parameters". To enter Level mode: Press SELECT and move flashing bargaph LED to position 0. With the bargraph flashing at position 0, press and hold SELECT until the parameter LEDs scroll down twice. The Ramp Up LED will light up. Press SELECT and one bargraph LED will start flashing. Position 0 parameters can now be redefined. To re-define position 0 parameters: The Ramp up parameter LED must be flashing. The bargraph LED must be flashing at the position that has been previously programmed (position 7 if the product is just out of the box). Use the UP/DOWN arrow keys to move the flashing bargraph LED to the required position according to Table : "Level Parameters" and then press SELECT. The next parameter LED (Ramp down) will start flashing to indicate that it can be adjusted. The bargraph LED will also start flashing at the position that has been previously programmed (position 7 if the product is just out of the box). Use the arrow keys to move the flashing bargraph LED to the required position according to Table : "Level Parameters" and then press SELECT. These steps are repeated until all parameters have been set. Ramp shapes can be selected in the same Ramp Shapes way. To save and exit Level mode: To save and exit Level selection procedure, press and hold SELECT until the parameter LEDs scroll down twice. Running with the customised ramp: After Level procedure has been completed the device will store the parameters in position 0. The bargraph LED in position 0 will light up continuously during operation. Defaults: Enter Level mode as previously described. When the bargraph LED is flashing, press and hold the UP and DOWN arrow buttons simultaneously until the parameter LEDS scroll twice. This resets all the ramp settings to factory default. Attention! If no button is pressed for several seconds during Level or Level procedures, the product goes out of the Level setting mode back to the previous ramp parameter combination.
