3.5.2 ST Controller Interlock I/O
J6 – INTERLOCKS – External Safety Interlocks (15pin Sub-D M)
Figure 3-11, Interlock Pinouts
NOTE: In the case that interlock inputs need to be paralleled (e.g.
only one safety switch is available for two interlock inputs), it must be
made sure that the Contact closure pins (+15VDC) are wired together and
the Return pins (GND) are wired together (or only one Return pin used).
Failure to do so will compromise correct functioning of the interlocks
(always satisfied).
Example: One safety switch to be used for VAC and HVAC interlocks:
Connect one side of contact to pins 2 and 8 and the other side to pins 1
and 7 (or to only one of the two).
