KMD-5540 ____ KMC CONTROLS Power Jumper Illustration 1—Controller Components Installation This section provides important instructions and guidelines for installing the KMD-5540. Carefully review this information prior to attempting installation. Note: The actual configuration of the interface will depend on the model. KMDigital connections are made to the left side of the interface and third-party equipment is connected on the right side. Mounting Use the four mounting holes to securely mount the interface inside a UL-approved Enclosed Energy Management Equipment Panel or other suitable protective enclo- sure. See Illustration 2—Mounting Hole Locations on page... -
Page 3: Input Connections
KMD-5540 CommTalk Protocol Interface Installation & Operation Guide Installation 6.0" 4.0" Illustration 2—Mounting Hole Locations Input Connections The following sections describe the input connections that can be made to the KMDigital input side of the interface. See the site plan wiring diagrams for specific requirements. RS-232 (EIA-232) Inputs RS-232 inputs are connected to the terminal in the upper left corner of the inter- face. Detail As a general rule in RS-232 wiring, the Red lead is the Receive (Rx) lead and the Black wire is the Transmit (Tx) lead. Connect the appropriate leads to the indicated connectors on the terminal. RS-485 (EIA-485) Inputs Make connections to a network using the RS-485 connector. Detail An End-of-Line connection will have only one wire attached to the A and B termi- nals. See EOL (End Of Line) Setting on page 5 for EOL switch setting. Use 18 gauge, twisted-pair, shielded cable with capacitance of no more than ◆ about 50 picofarads per foot for all network wiring. Belden cable model #82760 meets KMC requirements. Connect the nodes of the network in a daisy-chain arrangement. This means ◆... -

Page 6: Power Connection
Power Connection Connect the 24 VAC supply voltage (Class 2 transformer only) to the power ter- minals on the lower left side of the controller. Connect the neutral lead from the transformer to the GND terminal and the AC phase lead to the ~ (phase) termi- nal. Power is applied to the KMD-5540 when the transformer is plugged in and the power jumper is in place (see Illustration 1—Controller Components on page Configuration Prior to operating the KMD-5540, it must be configured using the Hardware Con- figuration Manager (HCM) application supplied with WinControl. See the Win- Control XL User’s Manual for additional information. Note: All devices on the same network must be configured for the same baud rate. Operation Once configured, programmed, and powered up, the interface requires very little user intervention. Controls and Indicators The following sections describe the controls and indicators found on the device. -
Page 7: Resetting The Controller
KMD-5540 CommTalk Protocol Interface Installation & Operation Guide Operation Removing the lamps will open the RS-485 circuit and isolate the KMD-5540 ◆ from the network. If one or both lamps are lit, it indicates the network is improperly phased. This ◆ means that the ground potential of the KMD-5540 is not the same as other de- vices on the network If the voltage or current on the network exceeds safe levels, the lamps operate as ◆ fuses to protect the KMD-5540 from damage. Resetting the Controller If the KMD-5540 appears to be operating incorrectly, or is not responding to com- mands, you may need to reset it. Note Resetting the interface will restore the factory default configuration. It may be necessary to re-configure the KMD-5540 with HCM to establish normal communications and operation. To reset the KMD-5540, proceed as follows. Remove the screw at the center of the the cover and remove the cover. Locate the jumper block next to the input pull-up switches (see Illustration 9). RESET JUMPER Illustration 9—Reset Jumper Block Remove power to the KMD-5540. Place a short on the RST pins. Use a jumper if a spare is available. Power up the KMD-5540. Wait until the RDY LED begins to flash normally. Remove power to the KMD-5540. Remove the short from the RST jumper. Reinstall the cover and screw. Power up the KMD-5540 and re-configure it if necessary. -
