1.4.2 Logic Input Connectors
The PCT has seven digital logic inputs. Each input is activated
by connecting the input terminal to the GND terminal with a dry
contact or an NPN (current sinking) output.
If your PCT was purchased with the optional logic input
extension cable, the factory will have already installed wiring
that provides the CNT-1 and HOLD inputs on a six foot
extension cable terminated in a four pin Molex Minifit Jr
connector as diagrammed to the right.
Even if the logic input extension cable is installed, it is still
permissible to use the customer logic input connector to
connect other devices to the PCT. The CNT-1 wire of the
extension cable is connected in parallel with the CNT-1 screw
terminal on the customer logic input connector.
