Interlock output J3 Each HSM channel has a set of interlock output contacts that are available
through connector J3A and J3B (one channel per connector). These interlock
contacts change state when an interlock line goes active and can be used to
control external devices.
Run/Stop output J3
Each HSM channel has a set of Run/Stop Output contacts that are available
through connectors J3A and J3B (one channel per connector). You can use
these contacts to control external devices.
The run/stop contacts respond to the function generator run/stop states for
the test station where the HSM is assigned.
Interlock input J3
Each HSM channel has a set of interlock inputs that are available through
connector J3A and J3B (one channel per connector). External switch
contacts or logic signals connected to the interlock input can initiate a station
interlock.
Program interlock J3 Each HSM channel includes a program interlock input from an external
mechanical switch that is available through connector J3A and J3B (one
channel per connector). External switch contacts connected to the Program
interlock input can initiate a program interlock.
A program interlock occurs when the external switch contacts are open.
Note For Series 793 Controller applications, a program interlock stops the
function generator for the station where the J3 Interlock connector is
assigned. The J3 Interlock connector is assigned to a station based
on the HSM module chassis-slot position.
