4.3.4 AC-2000 SE Terminals
1.
Not used
.
2.
Communications
: Three terminal blocks for PC communication using the optional multiplexor,
MUX-2
.
o
RX
:
Receive into
AC-2000 SE
. With multiple controls, connect all the RX pins together.
Connect to TX at Multiplexor only.
o
TX
:
Transmit from
AC-2000 SE
With multiple controls, connect all the TX pins together.
Connect to RX only at Multiplexor only.
o
COM
:
Ground reference for communications. Do not connect shields to this pin. Connect
to COM at multiplexor also.
3.
Temperature Sensors
: The temperature sensor is a 2 wired black shielded cable thermistor
(RTS-2). Connect one wire to the temperature sensor terminal and the other to common
(Polarity does not matter).
4. Analog Inputs:
o
An.1
:
Humidity sensor with wire connections according to wire colors.
o
An.2
: Humidity Outside Humidity input. Connect the White wire of the Humidity sensor to
An.2 and the Red and Black together with the Humidity input Red and Black.
o
An.3
: Pressure sensor (Connect
Red (+)
wire
An.3;
Black (–)
Common).
5. Analog Outputs:
o
An.1
:
0 to 10V- Light Intensity control signal.
o
An.2
:
0 to 10V- Variable speed control signal.
6. Digital Inputs:
o
Dig 1
:
Feed overtime alarm input or wind direction selection.
o
Dig 2
:
Feed counter.
o
Dig 3
: Water meter.
7.
Relay Extension
:
Com
- The relay extension box such as the
REB-8
may be located up to 10
feet from the
AC-2000 SE
. Do not connect the shield to this terminal. Connect the shield to
earth ground only at one end of the cable to avoid ground loops.
o
Data
: This line carries data to the relay extension.
o
Clk
: This line carries a clocking signal for use by the relay extension.
