Relay-controlled UCM

Relay-controlled UCM

Completely independent from the type of lift control and the A3 actuator.


REA3 control detects the A3 error (UCM) and can be used for any type of lifts with any A3 certificated (EC-type examination) stopping elements (brake actuators) like:

  • overspeed governor with safety gear,

Besides this system is completely independent from the type of lift control and can also be used for retrofitting and modernisation of existing lifts!

  • Actuation of A3 brake actuator in case of UCM
  • Monitoring of the magentic switches (Door zone)
  • for safety circuit voltage of 24V to 230V AC/DC
  • DIN rail mounting in control box
  • 24VDC supply connection and involvement in safety circuit (2 taps)
  • Installation and connection of the redundant solenoid switch using the supplied mounting kit (door zone monitoring)
