Safety data values
The safety data is valid for the default design of the safety circuit described in this
manual. If the final design is different from the default and the customer has ordered
safety data calculations (option +P947), ABB calculates new safety data and delivers
it separately to the customer.
The safety data calculations are based on the assumption that the emergency stop
is used once a month.

1)
DC for low demand mode of operation is 90% (determined by the DC of the worst component in the subsystem).
2)
T1 = 20 a is used with high demand mode of operation. T1 = 2 a or 5 a is used with low demand mode of operation.
