Adaptation unit
Tina 5A
Function
The Tina 5A is designed for bypassing of safety devices con-
nected to the Vital/Pluto safety circuit and for supervision 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 indication is required de-
pends on the specific 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 first of the safety devices intended to bypass. The si-
gnal 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 example 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
Approvals:
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
– supervised lamp indication
– Indication of status by LEDs
S2 is used if:
– an odd number of dynamic safety units is to be bypassed
using an odd number of dynamic safety units, i.e. the sum
of Tina + Eden and Spot units (incl. Tina 5A). See drawing
HE3824C
– an even number of dynamic safety units is to be bypassed
using an even number of dynamic safety units, i.e. the sum
of Tina + Eden and Spot units (incl. Tina 5A). See drawing
HE3824F
S3 is used if:
– an odd number of dynamic safety units is to be bypassed
using an even number of dynamic safety units, i.e. the sum
of Tina + Eden and Spot units (incl. Tina 5A). See drawing
HE3824D
– an even number of dynamic safety units is to be bypassed
using an odd number of dynamic safety units, i.e. the sum
of Tina + Eden and Spot units (incl. Tina 5A). See drawing
HE3824E
The total number of dynamic safety units is calculated by
adding the number of Eden, Spot and Tina units connected in
the Vital circuit. See the connection examples HE3824C, D, E,
F or G.
