Adaptation unit Approvals: Tina 5A TV NORD Application: Bypassing of safety device connected to the dynamic safety circuit and for supervi- sion of lamp indication. Features: One or more safety devices can be bypassed 5 supervised lamp indication Indication of status by LEDs Function S2 is used if: The Tina 5A is designed for bypassing of safety devices con- an odd number of dynamic safety units is to be bypassed nected to the Vital/Pluto safety circuit and for supervision of using an odd number of dynamic safety units, i.e. the sum lamp indication. of Tina + Eden and Spot units (incl.

See drawing HE3824C During bypassing of safety devices e.g. a light grid or an an even number of dynamic safety units is to be bypassed interlocked gate, it must only be possible to allow the bypass using an even number of dynamic safety units, i.e. the sum function if a lamp indication is on. The lamp indication must of Tina + Eden and Spot units (incl. Tina 5A). See drawing therefore be supervised. Whether indication is required de- HE3824F pends on the specific situation and result of risk analysis. S3 is used if: When the Tina 5A receives a coded dynamic signal to S1 and an odd number of dynamic safety units is to be bypassed the bypass indication lamp is on (connected across L1-L2), a using an even number of dynamic safety units, i.e. the sum bypassing output signal is provided on S2 and S3. A broken of Tina + Eden and Spot units (incl. Tina 5A). See drawing or short circuit in the indication lamp leads to an interruption HE3824D of the bypass output signal on S2 and S3, therefore stopping an even number of dynamic safety units is to be bypassed the bypassing. using an odd number of dynamic safety units, i.e. the sum of Tina + Eden and Spot units (incl. Tina 5A). See drawing The dynamic signal to S1 on Tina 5A must be the input signal HE3824E from the first of the safety devices intended to bypass. The si- gnal can be connected via output contacts from a safety relay, The total number of dynamic safety units is calculated by a safety timer or be initiated via a unit providing the dynamic adding the number of Eden, Spot and Tina units connected in coded signal as for example an Eden sensor or a Spot light the Vital circuit.
