Power Supply NET Component Overview

  • Modules: Mains filter, Transformer, Fuse (SI 2AT)
  • Capacitor: 8200 μF / 63 V
  • Mains Connection: 230 V / 6 A / 50 Hz (or 220 V)
  • Connections: Phase (Ph), Neutral (N), Protective ground (E)

Controller PCB STP - Inputs & Safety

Page 2/4 Reference

Safety Connections (Sensors)

  • SIS (Close safety): Active = Open (Bridge if no SIS connected)
  • SIO (Open safety): Active = Open (Bridge if no SIO connected)
  • SSK: Combined safety contact

Control Inputs

Input Type Signal Name Logic / Condition
Electric Strike Bolt contact 24 V DC
Emergency Stop Emergency stop Connect for master/slave systems to both operators
Release Trigger RAD 290/AKA / AKI Outer/Inner release (Active = closed)
Indication VAK Lock indicating contact

Note on Fire Protection System: Bridge if emergency stop is not connected. Depending on configuration: Currentless = closed OR Currentless = open.

Control Panels (BDE) & CAN Bus

Page 3/4 Reference

  • J13 Connector: CAN-H, CAN-L (Leads twisted in pairs), +24V, +35V
  • BDE Options: BDI (Internal), BDI-M, FPC (Flash Programmer), Mechanical control panel (Toggle switch)
  • Master/Slave: Connections for Primary 1/2 and Secondary 1/2

Battery Backup & Master/Slave Connection

Page 4/4 Reference

Battery Unit (DFA 127)

  • Output: 24V DC
  • Relay: RL 1 (Max 48 VDC 8A)
  • Functions: Discharge, Volume, Mute (High/Low)

Dual Operator Connection (Primary / Secondary)

For double-leaf doors, the operators are linked via CAN bus (J13) and potentially Emergency Stop loops (J4).

  • Link Cable: 2 x 2 x 0.25 mm² (twisted pairs)
  • Signals: CAN-H, CAN-L

7.2 Cable Layout

IMPORTANT! Never use the main switch to disconnect the system from the power supply during the night!

Installation Specifications

  • Mains Voltage: 230V 50/60Hz
  • Fuse: 10A

  • Conduit: Tube 16 mm empty, max. length 8 m

Recommended Cable Types

Application Cable Spec
Mains (230V AC) 3 x 1.5 mm² (Ph + 0 + E)
Sensors / Logic (24V DC) 4 x 0.25 mm²
Data / CAN Bus 2 x 2 x 0.25 mm² (Twisted pairs)

Component Abbreviations

  • BDE: Control panel
  • HS: Locking contact
  • RAD: Motion detector (sensor)
  • TOE: Door locking
  • NA: Button, emergency stop, 2-pin
  • VAK: Main switch 2-pole (or specific locking trigger depending on context)
