AMX PCS2 Installation Manual

Overview
The PCS2 Dual Power Current Sensor (FG427) detects the 110 VAC current drawn by
equipment plugged into the onboard AC receptacles, and the LED status indicators assist
with monitoring system applications.
The PCS2 (FIG. 1) features adjustable sensing levels for high (full-on), low (standby), and
no-power (off) power levels for up to two devices and comes complete with a built-in power
supply.

Installation
The PCS2 is simply plugged into a 120 VAC three-hole wall outlet to obtain power. Refer to
the Wiring Guidelines section for more information.
1. Connect the STBY and ON outputs to the appropriate system inputs.
2. Plug the device that the PCS2 is sensing for power status into the PCS2 AC
receptacle.
3. Plug the PCS2 into an AC outlet.
Rack mounting the PCS2
To rack mount the PCS2 using the optional AC-RK Accessory Rack Kit:
1. Remove any connected power and communication connectors from the rear panel.
2. Remove the two screws on the front panel of the PCS2.
3. Remove the front panel and the space bracket behind the panel.
4. Remove the rubber feet on the bottom of the unit, if necessary. Insert a scissors blade
or other sharp object into the side of one of the rubber feet and pull it off.
Do the same to remove the other three rubber feet.
5. Place the unit in the appropriate opening in the AC-RK.
6. Place the front panel of the PCS2 on the front of the rack over the unit and secure the
front panel using the two screws removed in step 2.

Wiring Guidelines
The Wiring Specifications table lists wire sizes and the maximum lengths allowable between
the PCS2 and the Central Controller. The maximum wiring lengths are based on a minimum
of 13.5 volts available at the power supply output.
The PCS2 requires a local +12 VDC power to operate properly. The maximum wiring
distance between the power supply and PCS2 units are determined by power consumption,
supplied voltage, and the wire gauge used for the cable.
To reduce the possible effects of ground loop noise in the video, use a single-source power
supply mounted within distances specified in the following table.

Note: Do not connect power to the PCS2 until the wiring is complete.
Preparing Captive Wires
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive
wires.
Note: Never pre-tin wires for compression-type connections.
1. Strip 0.25 inch (6.35 mm) of insulation off all wires.
2. Insert each wire into the appropriate opening on the connector according to the wiring
diagrams and connector types described in this section.
3. Turn the flat-head screws clockwise to secure the wire in the connector. Do not over-
torque the screws; doing so can bend the seating pin and damage the connector.
PCS2 to AXC-INP8
Connect the PCS2 output ports to the AXC-INP8 input ports, as illustrated in FIG. 3.
Follow the illustration for Input 1 through Input 8. Set the jumpers of the associated inputs on
the AXC-INP8 to Switch mode. All Switch mode inputs and the Card-Frame share common
GND.
