Vital - safety controller
Control of an entire safety system based on the
dynamic safety circuit
Vital is based on a single channel safety
concept where multiple safety sensors can
be connected in series and monitored with
a single safety controller. A dynamic signal is
sent from Vital through all connected sensors,
and then returned to Vital which then evaluates
the received signal. As each safety sensor
inverts the signal, it is possible to detect short
circuits or faults in any of the sensors. Vital
2 and Vital 3 are designed for use with ABB
Jokab Eden sensors, Tina components and
Spot light grids or similar products. Vital 2
and 3 are both safety controllers with two
safe input functions and two output groups,
the only difference between the two models
being in the input configuration.

Connection of S1
Even numbers of sensors (Eden + Spot T/R + Tina) require a connection
between B1 and S1. S1 is not connected for odd numbers of sensors. Odd
number, no connection between B1 and S1.
