Product Information Product Information The Power Current Sensors (PCS) and Dual Power Current Sensors (PCS2) provide power current status for AMX equipment. Examples of such equipment are video projectors, monitors, audio receivers, and VCRs. The PCS and PCS2 detect the AC current drawn by the equipment plugged into its AC receptacle. You can adjust either the PCS or PCS2 to detect full on, full off, and standby power levels. Specifications The following tables list specifications for the

Installation Installation The PCS requires +12 VDC (+11 VDC to +17 VDC @ 20 mA minimum) for operation; the PCS2 is simply plugged into a 120 VAC three-hole wall outlet to obtain power. PCS and PCS2 Installation 1. Provide +12 VDC power from the Central Controller or external power supply, and connect it to the port on the PCS. Refer to the Wiring Guidelines section on page 3 for more information. 2. Connect the STBY and ON outputs to the appropriate system inputs. Refer to the Wiring Guideli

Installation Do not connect power to the PCS/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. 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 clockwis

Calibration Calibration The PCS and PCS2 work by setting a threshold. The STANDBY threshold is set be-tween the current draw of the OFF state and that of the STANDBY state. The ON threshold is then set between the current draw of the STANDBY state and the ON state. The PCS2 contains two major circuits, each independent of each other. Each if these major circuits contain two sub-circuits, the ON and STANDBY circuits. The following paragraphs will address the sub-circuits for each major circui

Calibration ON power level STANDBY power level FIG. 7 Standby and On level relationship If the unit has both STANDBY and ON states, follow these steps: If the unit only has an ON state, or if the PCS is sensing the ON state, perform step 1. If you are using only the STANDBY mode, focus on steps 3 and 4. 1. Turn the STANDBY and ON potentiometers (POTs) clockwise until they stop. 2. Plug the PCS into an outlet and plug the unit (the device you are monitoring) into the PCS. This power provides

Calibration PCS2 Calibration When extreme accuracy is required for calibration, allow the PCS2 to warm up for a minimum of 15 minutes before calibration. The following procedures are used for both circuit 1 and circuit 2. Calibrate each circuit independently. If the device only has an ON state, either STANDBY or ON can be used in the following steps. 1. Plug the PCS2 into a power source. 2. Connect the device. 3. Turn both POTS all the way counter clockwise. At a maximum, this is 20 full turns

Operation and Programming Operation and Programming PCS Operation When properly calibrated, the PCS senses current levels from sources that have one or two levels of power consumption. The STANDBY LED is on when the following occurs: ! The PCS is sensing the lower level of current (as low as 30 mA, or 4W at 120 VAC). ! The STANDBY output is low. The STANDBY and ON outputs are mutually exclusive. You can adjust the PCS to sense differences in STANDBY and ON current level as low as 30 mA. The

Operation and Programming ! A one- or two-second delay. ! Verification of status changes. During transitions between states, the PCS may take 1 to 2 seconds to stabilize and its output 2 indication may be incorrect. Failure to observe this delay may cause the Axcess, Axcent , or 3 Axcent system to repeatedly cycle power on the unit being sensed. PCS2 Programming When connecting a unit/system to the PCS2, be aware that a 1 or 2 second PCS2 circuitry stabilization consideration must be accounte
