The EMPS3IN is an input card for the EMOPS1 photosen-
sor. There are inputs for up to three photosensors with
local adjustment for sensitivity. The EMPS3IN should be
considered as a switch that sits on the Data bus. Instead
of switching with button pushes however it switches at spe-
cific light levels which can be programmed.
Hook-Up
Connect the EMPS3IN to the data bus using Cat. 5
cable with RJ45 connectors. Note all items on the bus
must be “daisy chained” and the beginning and end
items on the bus must have a terminator. If this is being
added to the bus in the middle this is not a problem. If
added at the end of the bus make sure the terminator
is removed from the previously last item to the new last
item on the bus.
If the ON LINE LED is not flashing re-check connections
and crimps.
Address and define per instructions in the EM1400
Quick Hook-Up Guide and System and Software Start-
Up Manual.
Connect up to three EMOPS1 photosensors to the
EMPS3IN inputs using two #18 wires. Note that these
connections are polarized and must be correctly con-
nected. One may run two #18 wires for a distance of
up to 1000ft. The wires must never be run in the same
conduit as high voltage wires. They must also be kept at
least 12” away from any parallel running conduit except
when crossing the conduit at right angles.
