  • Page 3: General

    It consists of a fail-safe control module and proper sensors or magnetic switches. With an open safety circuit ENA3 performs a self-test every 20th drive. A new drive is not allowed until the end of this test. (see document ENA3 self test-timing) The activation of the brake actuators and a control input to verify the correct operation of the actuators are implemented in the control module.

  • Page 4: Training Of The Installation And Operation Personnel

    The control may not be used in of other systems or particular in industrial plants. The safety control ENA3 may only be used for the case defined in EN81-20 5.6.7, to prevent of an unintendend movement of the car from a standstill.

  • Page 5: Technical Details

    EN81-50 Weight: 400g Environmental conditions: The ENA3 security control is designed so that it pollutes the environment as little as possible. It emits no pollutants and does not contain environmentally harmful substances and consumes very little power. Assembly / Fastening: Installation of security control should preferably be close to the elevator control.

  • Page 7: Optimization Of The Number Of Necessary Traveling Cable Wires

    • This button has no function during normal operation. It serves only to restart ENA3 safety control after an error. The button must be pressed briefly. If the button is jammed or otherwise remains in the pressed state, the safety circuit will not come into operation again.

  • Page 8: Commissioning

    • The car is located near the station with closed doors. • The distance to the station depends on the effectiveness of the UCM-braking device. • On the safety control ENA3 the LED „µP“ is flashing and the LED "FB" is lighted. All other LEDs must be off.

  • Page 9: Ucm-Error-Reset

    Diagnostic-input The function of the UCM-brake actuator or UCM-safety valve is monitored by a diagnostic switch. The contacts of this switch have to be connected to the diagnostic input of the ENA3 control. A LED (FB) indicates the correct function.

  • Page 10: Error Detection

    If the UCM-brake actuator has no diagnostic switches or contacts available to connect to the ENA3 control, it can be assumed that the UCM-tested brake actuator already includes other equivalent ways of self-monitoring. Thus, the terminals 5 and 6 must be bridged, that the ENA3 control will still operate! Error detection: The ENA3 safety control is responsible, for detecting a specific error ( UCM-error) and in the case of an error, to initiate an immediate emergency stop of the lift.

  • Page 11: Self-Test Of Outputs

    Self-test of outputs: • On power supply or after a reset, ENA3 performs a self test for the first 5 times when the car is in a door zone with open safety circuit . After the first 5 trips the self-test is carried out periodically each 20th time.

  • Page 12: Maintenance

    The scope of delivery includes the safety control ENA3, the manual and two special magnetic switches (Encoder Typ C1511FDA0300S) for monitoring of the door zone. The ENA3 safety control will be delivered in a plastic housing which can be fixed on a DIN rail and should be installed in the control box of the lift.
