Connecting the Retractable Cover Switch (Option only available with purchase of #863A
Expansion Board)
CAUTION:
Failure to heed the following may result in equipment damage.
The cover switch input must connect to an isolated dry contact output from the
retractable cover unit. Connection to an energized switch will damage the
Digital Nano/Nano+.
The contact may not be shared by any other device.
1) Installation will require:
a) Two conductor insulated cable 20 AWG, similar to Alpha Wire number 6642
(not
supplied).
b) External dry contact switch (provided by installer or retractable cover controller
manufacturer).
2) Remove the cover by loosening the (4) recessed Phillips
screws in the front corners of the cover.
3) Carefully release the RJ11 modular plug at the cover end of the
cable that attaches the 841-2C Display Board. See Figure 17
on page 33. Carefully set the cover aside.
WARNING:
Failure to heed the following may result in injury or death.
RISK OF ELECTRICAL SHOCK - Disconnect all AC input power before you
proceed with the next step.
4) Affix the (5) 4-40 x 1/4" standoffs to the (5) 4-40 Kept Nuts, provided with the STK0156
kit, in the pre-drilled holes at top of the chassis. Do not over tighten. See Figure 14.
5) Place the 863A Expansion Board onto the standoffs and secure with (5) 4-40 x 1/8" pan
head screws. See Figure 15.
6) Attach the flat ribbon cables (provided in the STK0156 Kit) to the 863A Expansion
Board in 2 places; JP1 on left and JP2 on right. Be sure that the red line is on left side
of the ribbon. See Figure 16.
7) Attach the flat ribbon cable from position JP1 on the 863A board, to the H1 position on
the power supply board. See Figure 16.
8) Attach the second flat ribbon cable from position JP2 on 863A board, to the H4 position
located on the Interface Board. See Figure 16.
9) Locate the terminal on the power supply board that has 4 male connectors. Remove the
existing black and white wires from these terminals
only
. They will be the top and
bottom positions. See Figure 17.
10) Using power cable ECA0348 provided in the STK0156 Kit, attach the multi-stack
connectors as shown in Figure 19 (top and bottom positions).
11) Reattach the black and white wires, removed in step 9, to the multi-stack male terminals.
Connections will go to the upper and lower male terminals. See Figure 20.
12) Attach the remaining ends from ECA0348 to the power terminals on the left side of 863A board.
Note Black wire on top and white on the bottom. See Figure 18.
13) Remove the knock out at the bottom of the Nano chassis and install the split gland
provided in the STK0156 Kit. Keep the gland loosened for next step. See Figure 21.
