Connections
Model AD1691 Power Connections
The AD1691 is supplied with a wall transformer (AD part
number TP8002) which can be connected to an outlet for
primary power.
Connect one of the 12 Volt AC leads from the TP8002
Transformer to one of the designated AC terminals on
the AD1691 (see Figure 3).
Connect the second 12 Volt AC lead from the TP8002
Transformer to the remaining AC terminal on the
AD1691.
Plug the TP8002 Transformer into a suitable 120VAC
power source (wall outlet, extension cord, etc.).
Code Source Connections
The AD1691 has three terminals for receiving control code
from a suitable Control Code Source such as the AD1202 P/T
Controller. The terminals are designated B for black, W for
white, and S for shield.
B Connect a black code wire from the B terminal of the
Control Code Source to the B terminal of the AD1691
Control Code Distributor (see Figure 3).
W Connect a white code wire from the W terminal of the
Control Code Source to the W terminal of the AD1691
Control Code Distributor.
NOTE: A 120Ω 1/4Watt termination resistor must be inserted
between the B and the W code wires (see Figure 3-A).
S Connect one end of the shield cable to the S terminal
of the Control Code Source. Connect the opposite end
of the shield cable to the S terminal of the AD1691
Control Code Distributor.
NOTE: Use 18 Awg, shielded, 2-wire cable, Belden 8760 or
equivalent for code line connections. The maximum
cable length is 5000 feet. For plenum wiring, use
Belden 88760 or equivalent.
- WARNING -
Do not connect the AD1691 to the primary power
source until ALL connections and switch settings
have been completed and verified.
