Distribution box VK3
For the peripheral interlock control system
Characteristics
The simple wiring of all the components in the peripheral interlock control system is based on the distribution box(es) VK3.
If there are several distribution boxes, these are connected by a pluggable control cable and power cable each.
The control terminals of the corresponding doors are then connected to the distribution box by also pluggable connection cables.
Product details
Technical data
| Material | hot-dip galvanized sheet steel |
| IP rating | IP 20 |
| Top hat rail | type TS35/7.5 according to EN 60715 |
| Placing | The maximum distance (length of cable) between a distribution box and a control terminal is 15 m. |
Amount
Number of required distribution boxes
Each distribution box disposes of 4 sockets each for the control and the power cables. These are used to connect the control terminals and, if needed, several distribution boxes.
Example 1: Interlock system with 4 adjoining doors
Here one distribution box is sufficient to connect all doors directly.
Example 2: Interlock system with 8 doors
To the distribution box 1 can be connected 3 doors. The 4th sockets are needed for the connection cables to the 2nd distribution box.
To the 2nd distribution box can be connected 2 doors as 1 socket each is needed for the incoming and one each for the outgoing cables. To the 3rd distribution box there can again be connected 3 doors as only one socket each is needed for the incoming connection cables.
Functions
Global emergency-open
If required, the function global emergency-open (when pressing one emergency-open switch, all doors are unlocked) is adjusted in the distribution box. To achieve this, there is fitted an additional relay (part no. 710921) with pluggable connection cable in only one distribution box of the interlock control system. It is simply clipped to the standard top hat rail in the distribution box. For the connector of this connection cable the additional socket X6 is reserved.
ATTENTION: When choosing the global emergency-open, the 6 core power cable has to be used!
Additional adjustable functions
The X5 terminal strip can be used for special functions. For example, to additionally lock any doors by a “privacy switch” (changing rooms) and to connect an external time control unit with display. The delivery of the distribution box includes a connector for the X5 terminal strip which facilitates an easy connection of these devices.
Dimensions
All dimensions in mm
The strain relief of the incoming and outgoing cables is achieved by fixing the cables with tie wraps to the two cable support brackets. The cable inlets are sealed dust proof by cellular material.
For fixing 4 borings of Ø 5.4 mm are provided in the casing of the distribution boxes.
