Wiring the OK Contacts
A set of isolated solid- state OK relay contacts is provided for optional
interface to an E- stop string, which controls power to the associated pumps.
The OK contacts are rated to drive an external 24V dc pilot relay (for
example, Allen-Bradley 700- HA32Z24) whose contacts can be incorporated
into the E- Stop string as in the following figure.
