4.2.1.1
Simulate a volt free input to manual shutdowns in the system by
applying and removing a link on the associated incoming terminals.
Input linked manual shutdown relay energised, input open circuit manual
shutdown relay de-energised. Each relay to be tested for energised to de-
energised to simulate external ESD pushbutton action.
