NOTE!
-
48VDC is factory supplied to J5-6 which is also factory jumpered to J5-3 (Digital Input #8,
minus). A customer provided ESTOP switch can be connected to J5-4 (Digital Input #8, positive). Note
that ground is furnished on J5-5 for a convenient connection to the other side of a customer provided
ESTOP switch. Digital Input #8 is factory configured for the ESTOP function. Customer-furnished
system ground applied to terminal J5-4 (Digital Input #8, positive) activates the ESTOP function. The
ESTOP function shuts down and locks out the rectifiers and opens the LVD’s. When the ESTOP signal is
removed, LVD’s close (if battery present). To restart the rectifiers; turn AC power to the rectifiers OFF,
wait 30 seconds or more (until the LEDs on the rectifier extinguish), then turn AC power to the rectifiers
ON.
