Product Description

The Trakstat series of electronic thermostats,by Paktronics, is a cost-effective alternative tothe use of mechanical and pneumatic control-lers. The Trakstat’s design flexibility and eco-nomical packaging offer a quality electronicthermostat which fits most original equipmentmanufacturer’s (OEM) temperature controlrequirements.

The Trakstat control can incorporate either aresistance temperature device (RTD), ther-mistor sensor, or type J or K thermocouple.Sensors of this type eliminate the problemsof capillary tube kinking and their calibrationis not affected by atmospheric pressurechanges.

The Trakstat’s versatile mounting capabilitiesoffer the OEM many options from which tochoose, including a factory-adjusted fixedsetpoint, snap-in control shaft, or remote po-tentiometer when panel space is limited. TheUL and CSA recognized 20 AMP output re-lay will handle most load requirements, or theoutput can be configured to drive a solid staterelay. The quick connect terminals allow forfast installation and service.

Accurate, repeatable temperature controlthrough a narrow deadband will result in bet-ter temperature control and a better productfor yourcustomers.

Calibration Pakstat Series ISimplified calibration decreases maintenance time with-out compromising accuracy. Our temperature control-lers can be factory calibrated for convenience or cali-brated as necessary at your facility.

1. Connect the PAKSTAT according to the wiringdiagram and instructions.

2. Attach the knob with the setscrews provided.

3. Turn the knob until the potentiometer is located atthe center of the dial.

4. Turn the power ON and allow 5 minutes for thesystem to stabilize.

5. Measure the temperature with an accuratethermometer next to the Pakstat sensor.

6. Loosen the knob setscrews and turn the knob,without turning the potentiometer, until the dial isset according to the thermometer reading.

7. Tighten the knob setscrews.

Calibration can now be performed on identical installa-tions by noting the position of the potentiometer andduplicating the setting. Offsets to compensate for sen-sor location can be calibrated. Contact the factory fordetails.

The BETA SERIES open-architecture elec-tronic temperature controls, by Paktronics,offers a low cost alternative to the use ofinaccurate mechanical or pneumatic thermo-stats, and expensive panel mounted tempera-ture controllers. The BETA SERIES con-trollers offer the flexibility of custom con-trols with the pricing and delivery of stan-dard products.

When coupled with the model LCD3000digital display, the BETA SERIES electronictemperature controllers provide the conve-nience of digital indication of actual processtemperature.

Product Description

The LCD3000 is a 3½ digit LCD display withresolution of 1°. With its flexible wire sen-sor, the BETA SERIES of controllers elimi-nates the problems of capillary tube kinkingand breakage. The quick-connect terminalsallow fast installation and service.

The BETA SERIES of controllers is usedwhere it is desirable to have accurate, repeat-able temperature control through a narrowdeadband.

CONTROL MODE

A. On/Off (contacts open on temperature rise).Generally used in heating applications where thereis a constant change in variables, such as load orsetpoint, in a static system. On/Off can be setup with a very narrow deadband (or differential)for tight control, or with a wide deadband foruse when mechanical limitations restrict cycling.

C. Fast Zero-Crossing Time Proportioning .25second minimum cycle time (bandwidth is field-adjustable to 10% of span). Proportioning maybe desirable in a dynamic system, where the load(such as flow rate) and setpoint are constant.

F. On/Off contacts close on temperature rise.Generally used for cooling applications.

K. Zero Crossing Proportional, reverse acting.

L. Window controller. Used where controllingaction takes place when the process temperatureis within a specific range of temperatures. Canalso be made so that action occurs when tem-peratures are above or below the window. Thistype of control might be used in an applicationwhere heat would be called for if temperaturesfell below the window, and cooling if thetemperature exceeded the window.

I. Display shows “LO BAT.”

J. Display is blank.

1. Control is not wired properly.

2. Control setpoint is too low.

3. Open sensor.

4. Control input power is not correct.

1. Control is not wired correctly.

2. Control setpoint too high.

3. Shorted sensor.

4. Sensor polarity (Thermocouple models only)

5. Control power.

6. Control cannot reach setpoint temperature.

1. Sensor placement.

2. Shorted sensor (Rtd or thermistor units only).

1. Shorted sensor (thermocouple only).

1. Control not wired correctly.

1. Display connector is reversed or connector ismisaligned.

1. Connect the heater in series with the relay contacts. Please notethat the output relay is internally isolated from power. See wiringdiagram.

2. Adjust the control setpoint above the sensor temperature.

3. Disconnect and measure the sensor continuity. If the sensorresistance is infinite, replace the sensor.

4. Check for the correct voltage and wiring at terminals.

1. Connect the heater in series with the relay contacts. Please notethat output relay is internally isolated from power.

2. Adjust the control setpoint below the sensor temperature.

3. Turn the system power off and disconnect the sensor. Replacethe sensor if the load remains off when the power is reapplied.

4. Check sensor polarity. For thermocouples, red wire is negative(-).

5. Check power connections at power terminals.

6. Heater is not sized properly. Increase heater wattage.

1. The temperature monitoring device is not placed next to thecontrol sensor. Move the monitoring device.

2. Sensor is not placed in the desired control area. Move the sensorto the area you want to control.

3. Knob is not positioned properly on the setpoint potentiometershaft. See calibration instructions.

1. Move the sensor closer to the heater.

2. Move any object that may be in contact with the sensor body.Additional thermal mass at the sensor will result in a slowerresponse.

1. Move sensor away from the heater.

2. Heater wattage is excessive. Reduce heater wattage.

1. Check sensor connections.

2. Measure sensor resistance. If resistance is infinite, replace sen-sor.

3. Verify that actual process temperature is less than 2000° (F or C).


2. Measure sensor resistance. If resistance is very low (~ 0 ohms),replace sensor.


2. Disconnect sensor and note whether display reads 1__ (opensensor indication). Correct wiring problem.

1. Check power connections. For 120V operation, power shouldbe connected to terminals 4 & 5 (terminal 3 should not beconnected for 120V operation).

1. Reverse display cable connector on one end only. Verify that allfour pins are connected.

2. Check display cable for damage. Replace cable if wires orconnector are damaged.

Over the years, Paktronics hasdesigned numerous electronictemperature controllers for spe-cial applications. Whether youneed one or 10,000, call uponPaktronics to build that specialcontrol.

Our R&D and engineeringstaff are ready to replace an ob-solete unit, or design a totally newcontrol for your new process orequipment. Our commitment toinnovation and development isdirected toward solving your tem-perature controlling problems andneeds.

Paktronics Controls has been syn-onymous with temperature controlsince the 1970’s. We are a division ofMaxitrol Company, who has been aleading manufacturer of gas pressureregulators since 1946.

Paktronics began in the industryby designing and manufacturing ana-log temperature controls. In order tomeet the needs of more sophisticatedequipment, we also design custom,microprocessor-based controllers.Our products can be found in medi-cal and dental applications, processcontrol, commercial foodserviceequipment, HVAC, laminating equip-ment and many other industrial andcommercial applications.

Taking the Right Steps Towards CustomElectronic Controls

Install a back-up control for critical applications where control failure could endanger life,limb, or property. A back-up control to serve as a high limit control is especially recom-mended for applications where a runaway condition could result. Paktronics Controls’products are not authorized for use as critical components in life support devices.
