ABB Jocab Safety Vital 2 Operating Instruction

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.
