Example:
Pump - G0400
HS - HS0001
Level Not Low - LAL0300
Level High High - LAHH0500
Condition: Pump can be started by HS0001 and when LAL0300 is not de-activated (meaning there is no LAL). Pump will trip if the LAL0500 de-activated (meaning there is LAHH).
Question?
In this case, what do you call HS0001 and LAL0300?
I come to know that the only permissive is LAL0300, before my knowledge is that both HS0001 and LAL0300 are permissive. Now I don't know how to call the HS0001?
