Product description With GEZE IO 420, GEZE components for door and window systems as well as the RWS-system of GEZE are controlled. The IO 420 is a coupler module for the networking of components and for the integration of non-bus- compliant components in the GEZE system.
In compliance with the manufacturer’s product liability as defined in the German "Product Liability Act", the inst- ructions included here must be noted and followed. Failure to comply releases the manufacturer from his statuto- ry liability. Only experts authorised by GEZE may carry out installation, functional checks and maintenance work. Guidelines The GEZE IO 420 fulfils the following standards: à...

Depending on the setting, alarm messages and actions are written into the log file. If the LED for microSD card is flashing, the microSD card must not be taken out of the slot. The IO 420 must be de- energised for the microSD card to be removed and inserted.
Object structure of BACnet for GEZE IO 420 The IO 420 offers 12 module types, each of which can be used with up to 22 objects. The BACnet objects are adapted to the selected module type. The respective EDE lists can be found in the annex to this document.

The object description is changed through the BACnet connection. Any BACnet configurator can be used for this. 3.3.3 Changing the BACnet parameters The IO 420 has four BACnet parameters which can be set using the GEZE service terminal ST 220 or by editing the microSD card. configuration file at the PC using the à...
Parameter setting GEZE IO 420 The first time parameters are set for the IO 420, the GEZE service terminal ST 220 should always be used. Once entered, the configuration file can be copied to a microSD card and adapted further at the PC if “IO420_V1.CON”...

GEZE IO 420 Module description The IO 420 offers 10 module types. The respective inputs/outputs are used in different ways depending on the module type. 5. 1 Module type “watchdog” The “watchdog” module type can be used for monitoring a door. When the monitoring function is armed, the door may only be opened by release.
Time switch interruption If “time switch interruptible” is enabled in the IO 420 configuration, the “time switch” state can be interrupted using the “lock” command. The state then changes to “locked” and the flag “time switch aborted” is set. No further change in state can take place when the flag is set.
GEZE IO 420 Module type “2 doors” The “2 doors” module type can be used for controlling two mutually independent doors. The connection of door contacts and lock feedback to the inputs is possible. The connection of a release switch is not designated for this module type.
GEZE IO 420 Module type “4 doors” The “4 doors” module type can be used for controlling four mutually independent doors. Only the connection of door contacts to the inputs is possible. The connection of a lock feedback or a release switch is not designated for this module type.
1 and 2 for this. Input 3 and 4 are used to evaluate the door feedback. With this module type, no fault messages of the drive can be evaluated via the IO 420, since the drive com- municates via the inputs/outputs rather than via RS485.
Module type “universal” With this module type, the IO 420 has universal control via inputs/outputs. Switches can be connected at input 1 and 4 for this. The inputs can be configured as ZSU masters and the ZSU master can be actuated via the respecti- ve switch or internal timer.
The module type “IQ Lock EL + Aut” is used to activate GEZE motor locks. IQ Aut is connected with the IO 420 via bus (terminal “ST 220”) and controlled accordingly. All the states and fault messages of IQ Aut can be read out and forwarded via BACnet.

The inputs and outputs of the IO 420 can be used as an IO extension for the TZ 320. KL 220 has 4 inputs and 6 outputs. Since the IO 420 has 4 inputs and 4 outputs, the configuration for the fifth and sixth output of the KL 220 is not evaluated.

à This type of module is a summary of “RSW+KL” and “DCU 1, 2 and 8”. TZ 320, DCU-GF and DCU-SF are con- nected by CAN. Terminals 45 and 46 of TZ 320 are connected to the GEZE BUS of IO 420. Thus, the inputs and outputs of IO 420 are used as terminal box for RWS.

Open “IO420_Flasher.bat” using the text editor. If the files reference is “IO420_V1.hex”, it must be changed to “IO420_V1”. CORRECT: “..\Flasher\STM32\ProgSTM32Pfs.bat 11 ..\FlashData\IO420\IO420_V1” Save file. Switch off the voltage supply for the IO 420. Connect the adapter cable (mat.no.: 130829) to the IO 420.
