Vital 3
Vital 3 is a safety controller that combines function-
ality with the quick and easy installation of safety
sensors. With two safe input functions and two differ-
ent output groups, Vital 3 offers the capability to
exclusively control smaller machine safety systems
that would otherwise have required a programmable
controller or multiple safety relays.
How the two output groups are controlled by the
input functions depends on which of the three operating
modes is selected (see Selection of operating mode).
Input Function 1
A two-channel safety circuit designed for opening
contacts, e.g. two-channel emergency stop or ABB
Jokab Safety's safety switch JSNY5. One channel is
fed with the dynamic signal and the other with static
+24 VDC.
Input Function 2
A dynamic safety circuit where ABB Jokab Safety's
safety sensors Eden, Tina and Spot can easily be
connected in series. Up to 10 Eden or Tina devices
can be connected in series per input function.
Output group 1: A safe relay output in a duplicated
series and a safe transistor output with output voltage
of -24 VDC.
Output group 2: A safe relay output in a duplicated
series and a safe transistor output with output voltage
of -24 VDC. In addition, output group 2 contains a
non-safe transistor output with output voltage of +24
VDC, intended for information. The output group can
have time delay from 0 to 1.5 s.
Selection of Operating Modes
Vital 2 can be configured to operate in one of three
operating modes M1, M2 or M3. The selection of
operating modes is done by connecting one of the
terminals M1, M2 or M3 to +24 V.
