1 Introduction

The Model 741 Temperature Controller is a compact stainless steel unit that can be connected to heating equipment, such as thermal cups, PPAs, and HPHT Filter Press heating jackets. This instrument is useful for monitoring and controlling temperature.

1.1 Document Conventions

The following icons are used as necessary in this manual.

NOTE. Notes emphasize additional information that may be useful to the reader.

CAUTION. Describes a situation or practice that requires operator awareness or action in order to avoid undesirable consequences.

MANDATORY ACTION. Gives directions that, if not observed, could result in loss of data or in damage to equipment.

WARNING! Describes an unsafe condition or practice that if not corrected, could result in personal injury or threat to health.

ELECTRICITY WARNING! Alerts the operator that there is risk of electric shock.

HOT SURFACE! Alerts the operator that there is a hot surface and that there is risk of getting burned if the surface is touched.



2 Safety

The Model 741 Temperature Controller is designed for temperature control applications in laboratory-scale equipment. Any other use is not recommended and may impair safety.

This temperature controller complies with the European Low Voltage Directive 73/23/EEC.

A 15 amp, 14 awg, 110V to 240V power is required with this instrument. This power cord is included.

Only use a Type J thermocouple.



3 Features and Specifications

The Model 741 has the following features:

• Controller Display –The digital display where the setpoint temperature is programmed and monitored. Refer to Section 3.2 for description of the display functions.

• Heater ON/OFF – The switch that starts and stops the heater. It lights when the instrument is heating.

• RS 232 Data Port – A communications port for collecting temperature data.

• Universal Thermocouple Jack – Connect a Type J thermocouple into this jack.

• Power Input – Connect power cord of the instrument that requires heating to this inlet.

• Main Power ON/OFF – This switch controls power to the temperature controller.

• Main Power Inlet – Connect the 15 amp, 14 awg, 110V to 240V power cord from the temperature controller to the wall outlet.

• Push Button Circuit Breaker – When the circuit is tripped (e.g., a fault or overload), the button pops out, indicating that it has been turned off. Push the button to rest it.

3.1 Controller Display Button Functions

Refer to Figure 3-3. The buttons are described as follows:

• OP1 – Lights when output 1 is ON; the unit is heating.

• OP2 – Lights when output 2 is ON; unit is cooling. (Not active)

• Page – Press this button to return to the home display or select a page.

• Scroll – Press to select a parameter. Press and hold this button to continuously scroll through the list.

• Lower (down arrow) – Press to decrease a value.

• Raise (up arrow) – Press to increase a value.

To return to the home display, press the Page and Scroll buttons simultaneously.

To scroll backwards, press and hold the Scroll button, while pressing the Raise key.

4 Basic Operations

Refer to Figure 3-1 and Figure 3-2.

1. Plug the Model 741 power cord into the power outlet.

A 15 amp, 14 awg, 110V to 240V power is required with this instrument. This power cord is included.

2. Plug the heating equipment into the Model 741.

3. Switch the main power (on back of the unit) to the ON position.

4. Insert a Type J thermocouple into the port.

5. If collecting temperature data, then connect your computer to the temperature controller’s RS 232 data port.

6. Set the required temperature (setpoint) using the Raise or Lower buttons on the Eurotherm display. The basic instructions for operating the Eurotherm 3216 are included in this section. For complete operating instructions, please visit www.eurotherm.com.

7. Turn the heater switch to the ON position. The heater switch is lighted when it is active.

4.1 Setpoint Temperature Instructions

1. From the home display, press the Scroll button until SP1 appears.

2. Press Raise or Lower buttons to set the temperature.



4.2 Auto-tuning Instructions

Auto-tuning is recommended, especially upon first-time use.

For proper tuning of the temperature controller, ensure that all test equipment is properly connected and prepared for running a test that is representative of a normal test setup.

Follow these steps to activate the auto tune feature.

1. Setup the test equipment with a typical temperature setpoint, but with the heater switch turned off.

2. From the default screen, hold the Page button down for a few seconds until this message appears: Lev1 GOTO

3. Press the up arrow to change to LEv2.



4. Wait a few seconds for CODE to appear as shown below.

5. Use the up/down arrows to change the code to 7.

6. Wait a few seconds. The screen will return to the default screen.

7. Press the Scroll key (about 9 presses) until ATUNE appears.

8. Press the up arrow to set ATUNE to On.

9. Press the Page button to return to default.

10. Now the message tunE will flash for the remainder of the auto-tuning process. Turn the heater switch to the ON position. The output will remain off for about one minute while the controller determines the steady state conditions.

After one minute, the system should turn on the output, and the heater switch should light up.

The auto tune process should take the temperature to 70% of the setpoint value.

When the process is complete, the display should stop flashing the tunE message.



5 Maintenance

The Model 741 has no user serviceable parts. For service and repair, contact Fann Instrument Company.

5.1 Cleaning

• Use a mild soap solution to clean the Model 741 exterior. The labels can be cleaned with isopropyl alcohol. Do not use water or water-based solutions to clean the labels.

• Clean the thermocouple probe after use. Wipe the probe with tissue paper and wash it thoroughly with water to remove sample residue. If the sample leaves an oily residue, then wash the probe with mild detergent and warm water.

5.2 Calibration

• Refer to the manufacturer’s calibration instructions for this instrument.

• Periodically calibrate the Type J Thermocouple according to your laboratory schedule and standard operating procedures.

5.3 Troubleshooting

Problem Cause Solution

Instrument does not work Circuit is tripped. No power.

Push circuit breaker button to reset.



Check power output and input. Turn the Main Power Switch to ON position.

No heat Heater is not activated. Setpoint Temperature not set properly.

Turn the Heater Switch to ON position. Set the setpoint temperature.

Heater Switch does not light when setpoint temperature is reached.

No power to heaters. Turn the Heater Switch to ON position.

Unstable Reading Thermocouple probe not in the sample. Dirty probe. Probe malfunction.

Place probe in sample. Clean the probe. Calibrate and/or replace.

Display says “ broken thermocouple”

Either thermocouple is not plugged in or has loose connection. Thermocouple is not working.

Firmly push the thermocouple into the jack. Replace thermocouple.
