Crestron CNECI-4A Electrical Control Interface with AC Electrical Control Interface with AC: CNECI-4A Description Functional Description The Electrical Control Interface with AC, CNECI-4A, is a wall-mounted interface for AC powered devices such as drapes, screens, and lifts. It is nearly identical to the CNECI-4 but the exception is that it draws operating power from an AC line that is independent of Cresnet system power.
Electrical Control Interface with AC Crestron CNECI-4A Physical Description The CNECI-4A is housed in a gray, metal enclosure with silk-screened labels on the front cover. All connections are made to the internal PCB through enclosure conduit knock-outs that are located on the top, left-side, and bottom of the enclosure. Also supplied is one 4-position terminal block and one 9-position terminal block.

Crestron CNECI-4A Electrical Control Interface with AC should be used in the following resistance equation to calculate the value on the right side of the equation. Resistance Equation R < 40,000 L x PF Where: R = Resistance (refer to table below) L = Length of run (or chain) in feet PF = Power factor of entire run (or chain) The required wire gauge should be chosen such that the resistance value is less than the value calculated in the resistance equation.
Electrical Control Interface with AC Crestron CNECI-4A NOTE: Review the Network Interconnection Diagram (latest revision of Doc. 5411) when making 4-wire connections.
Crestron CNECI-4A Electrical Control Interface with AC 1. Make sure that the Cresnet system and AC power circuits to be installed are turned off. 2. Remove the four CNECI-4A enclosure front cover screws. 3. Remove the six PCB mounting screws (do not remove the low voltage section dust cover) and remove the PCB. 4. Mount the CNECI-4A to the desired wall location. 5. Re-install the PCB with the six mounting screws. 6.
Electrical Control Interface with AC Crestron CNECI-4A SIMPL Windows Programming SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use programming language that is completely integrated and compatible with all Crestron system hardware. The objects that are used in SIMPL are called symbols. SIMPL Windows offers drag and drop functionality in a familiar Windows® environment. SIMPL Windows is Crestron Electronics' software for programming Crestron control systems.

Electrical Control Interface with AC Crestron CNECI-4A How to Create the Program Configuration Manager Use the Configuration Manager workspace (Project | Configure System) in SIMPL Windows to select and configure all the devices that need to be included into the system. For this example, from the Control Systems folder in the Device Library, select CNMSX-AV. From the Touchpanels (Wired) folder, drop and drag the CT-3000 symbol into System Views and set the NET ID to 03.
Crestron CNECI-4A Electrical Control Interface with AC Programming Manager Use the Programming Manager workspace (Project | Program System) in SIMPL Windows to select symbols and assign their respective signals. For this example, CT-3000 and CNECI-4A symbols were added automatically when the devices were added to the system in the Configuration Manager workspace.
Electrical Control Interface with AC Crestron CNECI-4A To assign signals to the four toggle symbols, follow the example shown below. The signals shown below are toggle symbol S-1 signals for relay 1. Toggle symbols S-2 through S-4 are assigned similar signal names using relay2, 3, 4 and input2, 3, 4, respectively.
Crestron CNECI-4A Electrical Control Interface with AC Problem Solving Troubleshooting The table below provides corrective action for possible trouble situations of the CNECI-4A. If further assistance is required, please contact a Crestron customer service representative. WARNING: Disconnect power before working on this unit. While power is connected, there are live components inside. WARNING: Relay terminals 1, 2, 3, and 4 may still contain voltage even after AC power is disconnected.
