General
Vital is based on a single-channel safety concept where several safety components (e.g. sensors)
can be connected in series and supervised with only one safety module. A dynamic signal is sent
from Vital through all connected components, and then back to Vital which evaluates the received
signal. Since each safety component inverts the signal it is possible to detect short circuits, or
failures, in a sensor. Vital 2 and Vital 3 are intended to be used together with Jokab ”Eden”
sensors, ”Tina” components and “Spot” light beams or similar components. Vital 2 and 3 are both
safety modules with two safe input functions and two output groups. The only difference between
the two models lies in the input configuration.
Eden
Eden – Adam and Eva is a non-contact safety sensor for use on interlocked gates, hatches etc.
The dynamic signal from Vital is transmitted via Adam to Eva which modifies it and sends it back to
Adam, which in turn sends it inverted to the next Eden in the safety loop. Since each Eden inverts
the signal, different inputs on Vital 2/Vital 3 shall be used depending on if an even or an odd
number of Eden sensors are connected in series.
Jokab Eden sensor
Tina
”Tina” is a product family from Jokab which converts the signal from sensors with contacts or
OSSD-outputs to the dynamic safety loop. A large number of “Tina” components exist. A Tina 2A
can for instance be used to invert the signal at a switch in order to make it possible to detect short
circuits over the switch. Tina 10A is used to connect a Focus light beam/curtain to Vital 2/3.

Spot
“Spot” is a safety light beam which is available in two versions, Spot 10 for distances up to 10 m
and Spot 35 for distances up to 35 m. The light beams can be mounted at different heights and be
angled around a machine using special mirrors and brackets. For indication there are LED´s on the
transmitter and on the receiver which indicate “contact” between transmitter and receiver and
safety status. The “contact” information is available via the light beam receiver connection cables.

Safety inputs Vital 2
Vital 2 has two single channel inputs for connection to dynamic sensors such as Jokab “Eden”
sensors and “Tina” components. Each input function has two input terminals, one for an odd
number of sensors and one for an even number of sensors.
Safety inputs Vital 3
Input function 1 is a dual channel input for closing switches where one channel is a dynamic signal,
and the other a static +24V signal. Input function 2 is a single channel input of the same type as in
Vital 2.
Output groups
There are two groups of outputs:
Output group 1: Q1 and Q2.
Output group 2: Q11, Q12 and Q13. (Q13 is non-safe)
Reset / Auto reset
There are two separate reset functions, Reset 1 and Reset 2. Depending on mode selection they
work a bit differently (see Mode selection). They can be set to manual or automatic reset
independently of each other with the inputs Auto reset 1 and Auto reset 2.
Manual reset
For manual reset a pushbutton shall be connected to X1 (Reset 1) or X11 (Reset 2). Monitoring
contacts of external devices shall be placed in series with the pushbutton. When manual reset is
selected X4 (for Reset 1) and X14 (for Reset 2) works as reset indicator outputs to which a lamp
can be connected.
Auto reset
For auto reset, input X4 (Auto reset 1) or X14 (Auto reset 2) shall be connected to +24V.
Monitoring contacts of external devices shall be placed between +24V and X1(for Auto reset 1) or
X11 (for Auto reset 2). If monitoring contacts are not used X1 and X11 shall be connected to +24V.

Time delay
Output group 2 can be off-delayed by connecting the inputs 0.5s and 1.0s to +24V. The system is
binary so connection of one of these inputs adds the corresponding time.
Connecting 0.5s = 0.5 sec. delay
Connecting 1.0s = 1.0 sec. delay
Connecting both 0.5s and 1.0s = 1.5 sec. delay
Mode selection
Both Vital 2 and Vital 3 can be set to work in one of the three modes M1, M2 or M3. Selection of
mode is done by connecting one of the terminals marked M1, M2 or M3 to +24V.
The following pictures show the logic for each mode of operation.

The Eden sensors are in this example regarded to be interlocking sensors on a guard that can be passed
and has therefore a reset function. The Emergency stop function has automatic reset since reset is made
on the device itself.
Note: Reset of emergency stop button or reset of the guard must not lead to start of any movement.
