Connection Examples of Sensors to Tina 8A

Tina 4A and Tina 8A

Tina 4A and Tina 8A are connection blocks equipped with electronic circuits which modify the coded dynamic signal in the Vital safety circuit.

The cable between Vital and Tina 4A/ 8A has conductors for:

• Power supply (24 VDC)
• Coded dynamic signal output/input
• Information signals from each sensor connected to the block

Each M12 connector on Tina 4A /8A contains:

• Power supply (24 VDC)
• Short circuit supervised input and output which require connections of Eden, Tina or Spot T/R
• Output information from sensor

NOTE: Several Tina 4A and Tina 8A units can be connected to one Vital unit. (See connection example HA3302B)

Connection Example according to Figure 1 and Electrical Drawing HH3300D

Connection 1

One Eden is connected directly to the Tina 8A. The Eden status is shown by an LED on the Adam sensor. A status information signal is also connected to Tina 8A.

Connection 2

One Focus safety light grid is connected to the Tina 8A via a Tina 10A.. The output from the Tina 10A is via a M12 connector. The connection between Tina 10A and Tina 8A is achieved using a cable with M12 connectors on each end.

The Tina 10A has two LED's which show the status of the light grid. The same status information signal is connected to the Tina 8A.

Connection 3

A Spot 10 light beam is connected directly to Tina 8A. A 'Y' connector M12-3B for M12 plugs is connected to the transmitter and the receiver. The status information shown on the Spot LED is also connected to Tina 8A

Connection 4

A safety mat (same for safety strip and safety bumper) is connected via a Tina 6 A to the Tina 8A. Two LEDs in Tina 6A shows the status of the mat. The same status information signal is connected to Tina 8A.

Connection 5

An emergency stop is connected via a Tina 2A. On the Tina 2A there is a LED which shows the status of the emergency stop button. The same information signal is connected to the Tina 8A.

Connection 6

A safety interlock switch is connected via a Tina 3A mounted directly on the switch. The output from the Tina 3A is via a M12 connector. The connection between the Tina 3A and the Tina 8A is therefore simply made with a cable with M12 connectors on each end. On the Tina 3A there is a LED which shows the status of the switch. The same information signal is connected to the Tina 8A.

Connection 7

A Spot 35, transmitter and receiver are connected directly to the Tina 8A via a M12-3B 'Y' connector. The status information shown by the LED on the Spot is also connected to the Tina 8A.

Connection 8

Tina 1A is a plug which has to be connected to Tina 8A inputs when no sensor is required, in order to complete the safety connection circuit.

Note: All input connectors on the Tina 8A must be connected to sensors or have Tina 1A plugs fitted.
