Case VF Motor Rated 6.7 KW at 340 VAC.

Select E-Shield (45ES150-) as 6.7 x (415/340) = 8.2 KW.

Preferred safety-line voltage type of E-Shield should be the same as the safety-line voltage type of the controller, i.e., AC or DC.

Functional Framework: During normal operation of the elevator, E-Shield monitors the incoming 3-phase power supply. In the event of a power failure (all three or any one phase failure), E-Shield takes command from the main controller by isolating safeties and the door system. During inspection operation of the elevator, E-Shield can be disabled. E-Shield checks if all regular safeties are operational and functioning correctly. If the safeties are bypassed, E-Shield logs the fault and terminates the operation. E-Shield checks for passenger load in the car by attempting to run the lift in alternate directions. If the passenger load in the car is less than the balanced load, the UP direction is selected; otherwise, the Down direction is selected. Once the direction is determined, the car is brought to the nearest floor in that direction. Upon arrival at the floor, the doors are opened in the case of auto-doors. The rescue operation terminates and control is handed back to the main controller for the resumption of normal operation.

Functions:

  • SFT (Safety Fault Trip): Ensures that the safeties are not bypassed electrically. At the beginning of the rescue operation, before closing the lift door, E-Shield checks if the doors are already closed. If the doors are already closed, E-Shield logs the fault and terminates the rescue operation. This feature can only be activated with doors that sag when there is no power supply to the door operator. However, during the rescue operation, after opening the door, E-Shield checks if the safety chain is open. If the safety chain is not open, E-Shield logs the fault and terminates the rescue operation, indicating an improper safety chain interconnection.
  • MPL_CHK (Motor Phase Loss Check): Checks for phase loss to the main motor while running.
  • DCE (Door Close on Exit): Closes the door after opening the doors, before exiting the rescue operation.
  • DCTO (Door Close Time-Out): Removes power to the door after the selection runs are completed and the rescue run begins in the selected direction.
  • BRK_1ST (Brake First Drops before Motor is De-energized): Intended for usage with high-efficiency gears or gearless systems. Additional hardware is required for this feature.
  • OCT (Motor Over Current Trip): Terminates the rescue operation if the motor current exceeds IMmax.
  • UCT (Motor Under Current Trip): Terminates the rescue operation if the motor current is less than IMmin.
  • OST (Motor Over Speed Trip): Terminates the rescue operation if the motor exceeds the specified speed. A speed sensor is required to enable this feature.
  • UST (Motor Under Speed Trip): Terminates the rescue operation if the motor falls below the specified speed. A speed sensor is required to enable this feature.
  • FAN (Cooling Fan Control): Controls the operation of the cooling fan.

Installation Guide:

  • BR_VR% (Brake Voltage Reduction): Reduces the brake voltage to a user-set percentage of the initial value (100%) after the specified 1PH_VRT time delay during the rescue run. This feature can be used to reduce brake coil heating and/or battery drain. Note: The feature is disabled if BR_VR% = 100%.
  • DO_VR% (Door Motor Voltage Reduction): Reduces the door motor voltage to a user-set percentage of the initial value (100%) after the specified 1PH_VRT time delay during door opening. Use DO_VR% with 1PH_VRT to reduce door banging during opening. Note: The feature is disabled if DO_VR% = 100%.
  • 1PH_VRT (1 Phase Voltage Reduction Time): Sets the time after which the 1-phase voltage is reduced to BR_VR% during the rescue run or to DO_VR% during door opening. Set the 1PH_VRT time to reduce door banging during opening. Note: Brake voltage reduction is not time-critical.

Foot Note:

All features are to be enabled for their functioning. Disable features only for diagnostic purposes. Never change parameters during the rescue operation as it could result in malfunctioning and even damage.
