  • the control module should be very universally applicable with regard to the motorized locks 40 and electric bolts to be connected. For this reason, a relay was selected as a potential-free switch to control the motorized locks 40 and the electric bolts. If a DC voltage is required to control switching elements, a fixed voltage can be switched via the corresponding output via the potential-free changeover switch. The fixed voltage output can be configured via a jumper (inside the control unit). There are 3 voltages to choose from: 6V, 9V or 12V max. 500mA. The fixed voltages are stabilized and suppressed (residual ripple ⁇ 20mV).
  • the control module (control unit 50) is supplied via mains voltage.
  • An encapsulated switching power supply is used as the power supply.
  • the fine-wire fuse is located inside the control unit 50.
  • Input voltages from 110 to 250 VAC 50/60 Hz can be connected using appropriate switching technology in the switching power supply.
  • the switching power supply supplies 12VDC output voltage, the 6 VDC and 9 VDC are generated from the 12 VDC via a fixed voltage regulator (on a cooling plate).
  • the control unit 50 can be supplied with voltage from the outside (emergency power supply).
  • a Pylocx emergency power supply is connected to the Pylocx contact point (electronic lock 16).
  • the voltage of the internal battery (9V) of the Pylocx emergency power supply is made available directly to the control module (control unit 50) via the center contact 165 of the Pylocx contact point (electronic lock 16).
  • the corresponding Pylocx transponder is then connected to the emergency power supply unit. Further operation is the same as in normal operation. It should be noted that the 9V emergency operation can only supply 12V locks to a limited extent.
  • the current through battery operation is also limited to 300mA.
  • the DC/DC converter is controlled via the emergency power input (innermost contact of the contact point) of the control unit.
  • the voltage (3.7 VDC) fed in here from the battery 322 from the electronic key 32 is stepped up to 12 VDC by the DC/DC converter.
  • This 12 VDC is fed to the power supply section of the control unit.
  • 12 VDC which the switching power supply generates from the 230 VAC, are now directly available for the internal electronics of the control unit and for controlling an external motorized lock. This means that no external power supply is required for operation.
  • a 5-pin contact strip is available to load the firmware of the microcontroller during the production process.
  • a software update of the firmware can also be carried out via this contact strip.
  • the contact strip is located directly on the printed circuit board of control unit 50 and is not accessible to the user.
  • EMC protection components were provided at the interfaces to the outside.
  • the MicroLAN, the control inputs and the universal input are protected by suppressor diodes, the external signal output is protected by a VDR overvoltage.
  • the MicroLAN line is protected by another varistor.
  • the emergency power line is also protected with a varistor.
  • a zener diode with PPTC is inserted to protect DC voltage.
