Tina 5A
Adaptation Unit
Function
The Tina 5A is designed for bypassing of safety devices
connected to the Vital/Pluto safety circuit and for super-
vision of lamp indication.
During bypassing of safety devices, e.g. a light grid or
an interlocked gate, it must only be possible to allow the
bypass function if a lamp indication is on. The lamp
indication must therefore be supervised. Whether indi-
cation is required depends on the specic situation and
result of risk analysis.
When the Tina 5A receives a coded dynamic signal
to S1 and the bypass indication lamp is on (connected
across L1-L2), a bypassing output signal is provided on
S2 and S3. A broken or short circuit in the indication
lamp leads to an interruption of the bypass output signal
on S2 and S3, therefore stopping the bypassing.
The dynamic signal to S1 on Tina 5A must be the input
signal from the rst of the safety devices intended to by-
pass. The signal can be connected via output contacts
from a safety relay, a safety timer or be initiated via a
unit providing the dynamic coded signal, as for exam-
ple an Eden sensor or a Spot light beam. The dynamic
output from S2 or S3 is connected to the output of the
safeguards to be bypassed.
S2 is used if:
• an odd number of dynamic safety units is to be by-
passed using an odd number of dynamic safety units,
i.e. the sum of Tina + Eden and Spot units, including
Tina 5A. (See Connection Example HE3824C.)
• an even number of dynamic safety units is to be by-
passed using an even number of dynamic safety units,
i.e. the sum of Tina + Eden and Spot units, including
Tina 5A. (See Connection Example HE3824F.)
S3 is used if:
• an odd number of dynamic safety units is to be by-
passed using an even number of dynamic safety units,
i.e. the sum of Tina + Eden and Spot units, including
Tina 5A. See (See Connection Example HE3824D.)
• an even number of dynamic safety units is to be by-
passed using an odd number of dynamic safety units,
i.e. the sum of Tina + Eden and Spot units, including
Tina 5A. (See Connection Example HE3824E.)
The total number of dynamic safety units is calculated
by adding the number of Eden, Spot and Tina units con-
nected in the Vital circuit. See the Connection Examples
HE3824C, D, E, F or G on pages 5:45 - 5:47.
Application
■ Bypassing of safety devices connected
to the dynamic safety circuit and for
supervision of lamp indication
Features

passed
■ Supervised lamp indication
■ Indication of status by LED

Bypassing of Eden and Tina Units
If one or more Eden or Tina units are by-
passed by a Tina 5A, a diode, such as a
1N4007, must be inserted with forward cur-
rent out from pin 4 of the last bypassed unit. If
one or more Eden or Tina units are bypassed
by one or more Eden or Tina units direct to
each other, a diode, such as a 1N4007, must
be inserted by the last unit in both loops
with forward current out from pin 4. Refer to
example HD3801A. In the case of bypassing
of a Tina 10A, B or C, or of more than one unit
towards each other, it is recommended that a
Tina 5A or M12-3M is used. See the Connec-
tion Examples HE3824C, D, E, F or G.
