The transformer must be sized to provide adequate power to the Tracer MP503 I/O module (10 VA) and output devices, including relays, to a maximum of 12 VA per output utilized. The Tracer MP503 may be powered by an existing transformer integral to the controlled equipment, provided the transformer has adequate power available and proper grounding is observed.

    Inputs The Tracer MP503 has four inputs. Each input can be configured to be binary, thermistor, 0–20 mA, or 0–10 Vdc. You may have any mixture of these input types connected to the module. The factory-default input type is thermistor.

    To power these sensors, 24 Vdc is available from the Tracer MP503 circuit board. See Figure 5 on page 13 for wiring details. 0–10 Vdc inputs The Tracer MP503 can read a value from a sensor that provides a 0– 10 Vdc signal.

  • Page 21: Chapter 5 Network Variable Bindings

    Chapter 5 Network variable bindings This chapter describes how to use network variable bindings in Tracer MP503 I/O module applications. Overview The LonTalk communication protocol allows data to be shared between devices (stand-alone or with a BAS) on a LonTalk network. This is called peer-to-peer communication.

  • Page 22: Tracer Mp503 Bindings

    Chapter 5 Network variable bindings Tracer MP503 bindings The principal purposes of a Tracer MP503 I/O module are to gather data (sensor readings) for use by a BAS or peer device and to allow a BAS or peer device to control Tracer MP503 binary outputs. Therefore, the use of bindings is very important in Tracer MP503 applications.

  • Page 23: Sending Data

    A network variable output (nvo) sends data to other devices on the Lon- Talk network. The network variable outputs (including their SNVTs) that are commonly used in Tracer MP503 bindings are shown in Table 2. Table 2. Tracer MP503 network variable outputs...

    In this example, four different sensors are connected to a Tracer MP503. A thermistor reading the outside air temperature is connected to univer- sal input 1 on the Tracer MP503. A 4–20 mA sensor reading the outside air humidity is connected to universal input 2. Two binary inputs from a fire panel (Alarm Status and Fire Panel Trouble) are connected to univer- sal input 3 and universal input 4, respectively.

    Use the Rover service tool to create bindings. (See the Rover Operation and Programming guide, EMTX-SVX01B-EN.) Using the Rover service tool, select the network variable from the Tracer MP503 and then select the second Tracer MP581. The Rover service tool shows you only the vari- ables in Tracer MP581 #2 of the SNVT that matches the variable you selected in the Tracer MP503.

    AHU. The AHU and the exhaust fan follow the same schedule; for example, whenever the AHU runs, the exhaust fan runs. Bind an nvo on the Tracer MP581 to an nvi on the Tracer MP503 so the AHU and exhaust fan run together. Figure 8 shows the LonTalk network for this example.

  • Page 37: Chapter 7 Troubleshooting

    This chapter outlines some general troubleshooting steps that should be performed if there is a problem with the operation of the equipment con- trolled by the Tracer MP503. This chapter describes some common prob- lems; however, it cannot describe every possible problem. Troubleshooting that involves accessing live electrical devices must be conducted only by a properly trained and authorized electrician or trained technician.

  • Page 38: Initial Troubleshooting

    Step 3 Use your meter (set to measure ac voltage) to measure the voltage across the Tracer MP503 cir- ac power terminals on the Tracer MP503 (with ac wires connected). See cuit board prob- Figure 3 on page 7. If the voltage is approximately 24 V (20–30 V) on the terminals, the board is receiving adequate input power.

  • Page 39: Binary Output (Relay Output) Troubleshooting

    Look at the status LED for the binary output you are troubleshooting. (See Wiring problem “Binary output LEDs” on page 28.) If the LED is on, the Tracer MP503 is energizing its output relay. Use your meter (set to measure ac voltage) to measure the voltage across the binary output terminals you are troubleshooting on the Tracer MP503.

Is it bound to more than one network device? If it is bound to two devices, one may be commanding the binary output on while the other commands it off.
