1 Extending A99 Sensor ables ode No. LIT Issued June 17, 2014 IMPORTANT: The A99 temperature sensor is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the A99 temperature sensor could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the A99 temperature sensor. When the A99x Sensor is installed more than 50 feet (15.25 meters) from the controller, the resistance of the wire in the cable can create a significant deviation to the sensor reading. Use the following procedure to compensate for the deviation. Refer to the System 450 Series Modular ontrols Product Bulletin (LIT ), the A99B Series Temperature Sensors Product/ Technical Bulletin (LIT ), and the installation instructions for product specifications, detailed installation procedures, and important product safety information. Note: Use shielded wire when you install the sensor more than 50 feet (15.25 meters) from the controller. IMPORTANT: When connecting an A99 temperature sensor with shielded cable to an electronic controller, connect the cable shield drain lead to a low-voltage common terminal on the input sensor terminal block. Do not connect the shield at any other point along the cable. Isolate and insulate the shield drain at the sensor end of the cable. onnecting a cable shield at more than one point can enable transient currents to flow through the sensor cable shield, which can cause erratic control operation. 1. Use one of the following formulas to calculate the total wire resistance (error): a. Total wire resistance (ohms) = 2 x (Length of wire cable in meters) x (Resistance in ohms/meter) b. Total wire resistance (ohms) = 2 x (Length of wire cable in feet) x (Resistance in ohms/foot) Ohm Resistance of Typical Stranded opper Wire Wire Size ross Section Resistance Area American Wire Metric (mm) ircular mils Ohm/foot Ohm/meter Gauge (AWG) , , , , Determine the approximate temperature control point of the remote-mounted A99 Sensor, and then use that F or temperature in one of the following formulas to determine the ohms/degree at that temperature: Ohms/ = ( x ) Ohms/ F = ( x F) alculate the wire resistance error in F or : Error = (ohm wire resistance error)/(ohms/degree value at control point) Metric Example English Example If the A99 Sensor used for Sn-1 and Sn-2 inputs is installed 50 meters (164 feet) from the 450 control using 0.5 mm wire, the total wire resistance (error) is: 2 x 50 x.0352 = 3.52 ohms Then, if the A99 Sensor controls a process at 25, the ohms/ is: ( x 25) = 7.63 ohms/ Therefore, the error is: 3.52/7.63 = 0.46 So, the 450 control sensor inputs for Sn-1 and Sn-2 should be offset by If the A99 Sensor used for Sn-1 and Sn-2 inputs is installed 300 feet (91.44 meters) from the 450 control using 18 AWG wire, the total wire resistance (error) is: 2 x 300 x.0065 = 3.9 ohms Then, if the A99 Sensor controls a process at 70 F, the ohms/ F is: ( x 70) = 4.15 ohms/ F Therefore, the error is: 3.9/4.15 = 0.94 F So, the 450 control sensor inputs for Sn-1 and Sn-2 should be offset by -1 F. The following diagram illustrates how to enter this offset in the 450 Sensor Setup screen.

Where failure or malfunction of the System 450 modular control assembly could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the System 450 modular control assembly. Refer to the System 450 Series Modular ontrol Systems with Standard ontrol Modules Technical Bulletin (LIT ), the System 450 Series Modular ontrols Product Bulletin (LIT ), A99B Series Temperature Sensors Product Technical Bulletin (LIT ), and the installation instructions for product specifications, detailed installation procedures, and important product safety information. A 450BN-x ontrol Module with Relay Output, used with a 450SN-x Expansion Module with Relay Output and two A99 Series Temperature sensors, monitors and controls the water temperature in the cooling tower sump. On an increase in sump temperature (Sn-2), the low speed fan winding is energized by the normally open contact on the left side relay (OUTR2) of the expansion module, which is in series with the normally closed contact on the right side relay (OUTR3) of the expansion module. As temperature at Sn-2 increases, the right side relay energizes, breaking contact to the low speed winding and energizing the high speed winding. If the outside air temperature (Sn-1) falls below the desired lockout temperature, the System 450 control module de-energizes the fan circuit by breaking the power connection to the System 450 relay outputs (OUTR1). The control module relay output (OUTR3) references Sn-1 and de-energizes power to the fans when the outside air temperature falls below the desired lockout temperature. Set up the desired setpoints for each relay.

Where failure or malfunction of the System 450 control module could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the System 450 control module. Refer to the System 450 Series Modular ontrol Systems with Standard ontrol Modules Technical Bulletin (LIT ), the System 450 Series Modular ontrols Product Bulletin (LIT ), and the installation instructions for product specifications, detailed installation procedures, and important product safety information. You can use System 450 to measure a pressure difference across pumps, heat exchangers, and similar devices where you want to control a device using differential pressure. ompared to a Differential Pressure Transmitter (DPT), installing System 450 is simpler, requires less hardware, and is less labor-intensive, saving time and money. System 450 parameters are easy to configure and readjust, if necessary, making it much more flexible than a DPT. A DPT requires a manifold, a bleeder valve, isolation valves, a bypass valve, and associated piping. Only the isolation valves are required for a System 450 installation. In this example, a System 450 control system with two identical pressure transducers is set up to control pump speed based on the pressure differential detected between the Sn-1 and Sn-2 transducers. When Sn-1 and Sn-2 are the same Sensor type, the Differential Sensor (Sn-d) is automatically enabled and available for selection when you set up the control system outputs. When the Differential ontrol sensor (Sn-d) is referenced, the differential sensor value is always equal to Sn-1 minus Sn-2. The sensed differential value (Sn-d) between Sn-1 and Sn-2 is displayed in the System Status screens as either a temperature differential value (dift), pressure differential value (difp), or humidity differential value (difh). For example, if Sn-1 has a value of 58 and Sn-2 has a value of 55, Sn-d has a value of 3 (58 minus 55).

In this example, the 450EN-x ontrol Module controls head pressure on a water source heat pump for both heating and cooling. In this type of application, the head pressure is typically lower when the heat pump is operating in heating mode, and the pressure is higher when operating in cooling mode. AO1 is controlling the head pressure in the heating mode and AO2 is controlling the head pressure in the cooling mode. The analog output limiter function prevents the valve from excessive modulating.

45 A99 and TE-6000 Temperature Sensor Averaging ode No. LIT Issued June 17, 2014 IMPORTANT: The A99 and TE-6000 temperature sensors are intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the A99 and TE-6000 temperature sensors could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the A99 and TE-6000 temperature sensors. Note: Use shielded wire when you install the sensor more than 50 feet (15.25 meters) from the controller. In many applications, a single temperature sensor cannot provide an accurate temperature reading of the entire space. Sensors can be wired in a series/parallel arrangement to average the readings of all sensors in the network. When averaging sensor readings, you must always have the same type of sensor (A99 or TE-6000) and the same number of parallel-connected legs as there are series-connected sensors per leg. See the following diagrams for an illustration of how averaging can be accomplished using four or nine sensors. Note: The A99B Series Temperature Sensors and the TE-6000 Series Temperature are not compatible, and the sensors in the averaging arrays must be all A99B sensors or all TE-6000 sensors. IMPORTANT: When connecting an A99 or a TE-6000 temperature sensor with shielded cable to an electronic controller, connect the cable shield drain lead to a low-voltage common terminal on the input sensor terminal block. Do not connect the shield at any other point along the cable. Isolate and insulate the shield drain at the sensor end of the cable. onnecting a cable shield at more than one point can enable transient currents to flow through the sensor cable shield, which can cause erratic control operation. System 450 uses the A99 Series PT Silicon Temperature Sensors or TE-6000 Series 1000 Ohm Nickel Temperature Sensors. You can apply sensor averaging to System 450 applications.

In this solar heating example, a solar panel circulating pump is controlled by differential temperature (dift). When the temperature of the solar panel is 10 F above the temperature of the water in the storage tank, the solar panel circulating pump begins to run. When the differential temperature (don 1 ) is met, the normally open contacts of relay output 1 close, energizing 2 and starting the circulating pump. The pump cycles off when the differential temperature (doff 1 ) falls to 5 F. The room temperature circulating pump is controlled by the room temperature sensor (Sn-3) and the storage tank sensor (Sn-2). When heating is required, the normally open contact on Relay Output 2 (OUTR2) closes, energizing 1 and starting the room temperature circulating pump. Relay Output 3 (OUTR3) locks out the room temperature circulating pump if the water in the tank drops below 70 F, allowing the pump to restart when the water temperature rises to 75 F or higher.

Where failure or malfunction of the System 450 control module could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the System 450 control module. Refer to the System 450 Series Modular ontrol Systems with ommunications ontrol Modules (LIT ), the System 450 Series Modular ontrols Product Bulletin (LIT ), and the installation instructions for product specifications, detailed installation procedures, and important product safety information. The On Delay and Off Delay Timers (ONd and OFFd) delay the control response before it acts on the sensed value. You can use the delay timers to prevent the control from responding to momentary sensor value changes. ONd and OFFd, in addition to the Minimum On Timer and Minimum Off Timer (ONT and OFFT), can also be used to set up anti-short cycling control for your equipment or to stagger the start of staged equipment. In this example, a 450EN-x ontrol Module controls a two-stage cooling system that includes head pressure control and a high space temperature alarm. The space sensor senses the temperature in the refrigerated space. When the temperature rises, the liquid-line solenoid valve (connected to the OUTR1 output) is energized. As the suction pressure rises, the low-pressure suction transducer senses the rise in pressure, and the first compressor (connected to the OUTR2 output) starts after the on delay time expires. If the suction pressure continues to rise, the second compressor (connected to the OUTR3 output) starts, again after the on delay time expires. The on delay times prevent the compressors from responding immediately to changes in the sensor reading and prevent the compressors from short-cycling. When the head pressure rises, the high-pressure discharge pressure sensor (Sn-3) senses the rise. This causes the analog output signal OUTA5, which controls the variable-frequency drive (VFD), to increase, which starts the condenser fan at low speed. If the head pressure continues to rise, the control increases the signal, and the condenser fan speed is increased to meet the demand. The output limiter features (UPR and bnd) prevent the VFD from hunting (over-actuating). If the temperature of the refrigerated space exceeds the high temperature alarm value (of 5 F in this example) for a period of time equal to or greater than the time delay, the remote alarm activates. 450EN-x ontrol Module 450YNN-1 Power Module 450SN-x Expansion Module OUTR1, OUTR2 450SN-x Expansion Module OUTR3, OUTR4 450SPN-x Expansion Module OUTA5 Suction Pressure Transducer ondenser Pressure Transducer Space Temperature Sensor VFD Liquid Line Solenoid ompressor 1 ompressor 2 Alarm Wiring Diagram for a Two-Stage ooling Application with Remote ommunications Example R1 R2 R3 R4 1
