9 57YIMC0 Removing the IM Housing Cover IMPRTAT: Electrostatic discharge can damage controller components. Use proper electrostatic discharge precautions during installation, setup, and servicing to avoid damaging the controller. ote: The IM assigned to Address can initiate an emergency shutdown mode through BI. See the Emergency Shutdown Mode section for details Address IMPRTAT: Disconnect all power sources to the controller before removing the cover and changing position of any jumper on the controller. Failure to disconnect power before changing a jumper can result in damage to the controller and void any warranties Address 5 Address 6 The controller cover is held in place by four plastic latches that extend from the base and snap into slots on the inside of the housing cover. To remove the controller cover:. Place your fingers under the two cover lift tabs on the sides of the housing cover.. Gently pry the top of the cover away from the base to release the cover from the upper two latches. 3. Pivot the top of the cover further to release it from the lower two latches. Replace the cover by placing it squarely over the base, then gently and evenly push the cover on to the latches until they snap into the latched position. Communication Determining the Address The bus address switch sets a unique address for this controller on the YCCS communication bus. The default address setting is 55 (all switches in the position). You must change the default address. Set consecutive addresses 7 for IM controllers on the YCCS system bus. Use sequential addressing with no gaps in the device address range to ensure best bus performance. See Figure for address switch settings ote: The system bus has a maximum of IM Controllers. Emergency Shutdown Mode IM Address designates Binary Input (BI) as an optional global emergency shutdown input. If configured for emergency shutdown, when BI on Address closes, all equipment on the YCCS network shuts down. Binary utput (B) also closes for alarm horn activation. If you do not want to use emergency shutdown operation, assign BI on the IM at Address a different function. System Communication Riser See Figure 9 for an example YCCS System communication riser.

11 EndofLine (EL) Terminations Daisychained RS5 protocol networks require EndofLine (EL) termination to reduce interference. Interference is caused by signal reflection that occurs when data transmissions reach the end of a bus segment and bounce back (Figure 0). The high baud rates on MasterSlave/TokenPassing (MS/TP) bus applications require robust EL termination and strict adherence to the EL termination rules. n a YCCS System bus or Zone bus, only one EL termination is required due to the fewer number of devices on one bus and the shorter wiring length. Specifically, the System bus must always have a System Manager as the EL device, and the Zone bus must always have a Zone Coordinator as the EL device. Figure shows a YCCS EL wiring example. o EL = o Signal Cushioning (Bounce Back and oise) EL Provides Signal Cushioning (o Bounce Back) Figure 0: Interference 57YIMC0 o EL EL FIG:intrfrnc System Manager must be end of line for system bus System Manager Zone Coordinator must be end of line for zone bus VAV Zone Coordinator To Phone Line To Ethernet Hub Modem LA EL System Zone EL V To VAC LA EL System Zone SB SB ZB ZB SB SB ZB ZB EL V To VAC ther System Devices tape off To VAV Zone Devices Zone Sensor 3 CV Unit Controller AI AI Binary & Mod Simplicity Board Zone Coordinator must be end of line for zone bus LA CBP Zone Coordinator EL System Zone?

12 57YIMC0 Troubleshooting Use the following information to troubleshoot the IM controller on the YCCS System bus. Status LightEmitting Diode (LED) A green LED shows the power supply status to the IM controller. See Table 3 for a description of modes. Table 3: Status LED for (PWR) Mode Description ff o n is supplied by Primary Voltage (ormal peration) Communication Problems Several factors may influence the behavior of the System Communication. In addition, certain problems can affect the in multiple ways and have multiple symptoms, which makes the exact diagnosis difficult. For example, duplicate addresses on the can degrade performance, make the device go offline, or stop communication completely. Incomplete Address The IM controller must have the address set within the 7 on the System Communication ; other settings prevent the IM controller from communicating on the System Communication. Duplicate Addresses Two or more devices on a communication cannot have the same address. For example, two IM controllers cannot both have an address of 6. If two devices on the same communication bus have the same address, performance can degrade or serious communication problems may occur. These problems include the devices not coming online and all communication stopping completely. Check for duplicate addresses, in the following ways, depending on the severity of the situation: If the performance is degraded, check the address switch settings at the devices with unreliable communications. If a specific device is not communicating, remove the device with communication problems and check if the device address remains online at the System Manager or Zone Coordinator. If the communication problems are severe, and no communication is present, or you cannot determine where communication is unreliable, partition (disconnect and isolate a portion of the for testing purposes) and test the portion connected to the System Manager and Zone Coordinator controllers. Correcting Physical Communication Problems The communication bus is subject to a number of physical factors that can affect performance. Consider the following list of common physical problems that affect the communications bus: Check status LED to verify power at the controller Check wires Verify the wire is AWG (0.6 mm) 3conductor, twisted, shielded cable. Verify the shield is continuous and hardgrounded at one end. Check wiring Check for and eliminate TTaps (wire configurations that create a T shape) and star configurations. Ensure bus is wired in daisychain fashion. Verify that appropriate devices have three wires entering and exiting each terminal (devices at the ends of the trunk do not have this wiring). Check EL switch settings Verify the zone bus EL switch on the Zone Coordinator is set to and the Zone Coordinator is located at the end of the zone bus trunk. Verify that only the EL switch at the end of the system bus is set to and all other system bus EL switches are set to FF. Check connections, polarity, and lengths Verify communications loops are less than approximately 30 m (,000 ft) total in length. If you are using one transformer to power multiple devices, verify the device VAC power connection follows the polarity of the common and V terminations. Check for opens and shorts Check terminations Check for sources of interference YCCS Input utput Module (IM) Controller Installation Instructions

13 Check bus voltages: Check addresses () to must be within.0 to 3.0 VDC Check for duplicate addresses () to must be within.5 to.5 VDC Verify the address range is sequential () to () must be within 0.3 to.0 VDC ote: Values may fluctuate due to ongoing communications. This operation is normal provided the voltage is within the defined range. Repair Information If an IM controller fails to operate within product specifications, replace the unit.
