Install Other Accessories
WARNING!
Turn the main power off before
you make any electrical connections or set any
switches inside the operator.
You install other accessories to the 820 or 860 Operator
according to the terminal wiring diagram shown in
Figure 15.
Terminals 1 and 6 are the common for all installed
opening, stop, and reversing devices. Terminal 2 is for
your normally open (N.O.) opening device. Terminal 3
is for an N.O. partial opening (A/C) device
or
for an
N.O. closing device, depending on the logical mode of
operation you choose. If you do not install one of the
normally closed devices (a stop or reversing device),
then you need to connect its terminal (4 or 5,
respectively) to terminal 1 (or 6) with a jumper.
Terminal 6 is the common you should use for any 24
VDC accessory. Terminal 7 su24 VDC.
Terminals 8, 9, and 10 are for installing a warning light.
Terminal 8 is common. The warning light function
differs depending on whether you use terminal 9 or 10.
See the tables on the previous pages for more detail.
Terminals 11 and 12 supply high-voltage power when
the motor is running. You connect your main power
source to terminals 13 and 14.
Note
: Your standard 220 VAC power source
meets the specification for 230 VAC, +6 or
-10%.
If you are installing an 860 Operator without RC, it is
especially important that you install additional reversing
devices to compensate for the missing RC function.
Three sets of photocells can improve entrapment
protection (see Figure 16).
One set of photocells should protect the area where the
gate moves on opening and should be connected
between terminals 1 and 4 for stop logic. The other two
sets should protect the area of the closing gate, inside
and outside the property line, and should be connected
in series to terminals 5 and 6.
