Commissioning:
It is assumed that the magnet switch is properly installed and the
Door zone magnets were installed correctly.
The car must be in a door zone.
• Inspection of the correct mechanical fixation of the safety control
• Inspection of all connections and terminals
• Remove the orange plug and afterwards switch on the unit
• The 2 LEDs „Zone“ must be on (car at level)
• The 2 LEDs „µP“ must be on. Indicate that the safety system is working properly - no fault and all
relays are switched through.
• The LED „FB“ must be on. Indicates the correct function of the feedback switch (braking device).
• The LED „S“ must be on. Indicates when the safety circuit is activated. (Door closed).
• When safety circuit is open, the "S" LED must not light.
In the case of a negative test, one must assume a capacitive coupling in the safety circuit. This is to
be remedied on-site.
The orange plug must be connected again.
Now the lift can be tested.
All functions of the elevator controls should work properly.
Function test UCM-error:
Precondition for a meaningful review of the UCM function is a proper function of the lift itself and the
proper integration of ENA3 safety control.
Check before testing:
• After the correct installation of the ENA3 or pressing the reset button of the elevator
before the function test must make a Normal trip!
• All LEDs on the ENA3 safety control must be lighted.
• All connectors must be plugged correctly
Actual testing (UCM error tests)
• Disconnect the connector with the terminal numbers 10 and 11 (safety circuit).
• The "S" LED must switch off.
• Give a lift call.
• The car should be starting to move.
• As soon as the car leaves the door zone ENA-3 safety control initiates an emergency stop.
Effects of UCM-error tests:
• 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.
• The LEDs "µP" will flash 2 times with a subsequent pause of about 4 seconds.
