MTS 793 Controller Hardware
210
Cable specification • 15 contact type D male EMI connector.
• Backshell–EMI metallized plastic.
• Cable–24 AWG 4 connector with braided shield, with the braid
connected to a metallized plastic backshell at the chassis and to
ground at the emergency stop station.
Jumper plug required If connector J29 is not used, you must install a jumper plug to
maintain the integrity of the interlocks. Use jumper plug PN 100-007-
947B or jumper pins: 3-4, 5-7, 8-13.
J43 Interlock
Connector J43 Interlock contains one optically isolated interlock
input and one relay contact interlock output.
Note The intlk out relay (Pin 6) is normally energized when no interlocks
are active. So even though Pin 6 is a NO (normally open) relay
contact, it is actually normally closed when no interlocks are active.
Similarly, the intlk out relay (Pin 8) is normally closed when no
interlocks are active, so even though Pin 8 is a NC (normally closed)
relay, it is actually normally open when no interlocks are active.
