3 Features and Specifications
The Model 740 has the following features:
• Controller Display –The digital display where the set point temperature is programmed and monitored. Refer to Section 3.1 for description of the display functions.
• Heater ON/OFF – The switch that starts and stops the heater. The switch lights up when the instrument is heating, and goes out when temperature is reached.
• RS 485 Data Port – A communications port for collecting temperature data.
• Universal Thermocouple Jack – Connect a Type J thermocouple into this jack.
• Power Output – 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.

4 Basic Operations
Refer to Figure 3-1 and Figure 3-2.
1. Plug the Model 740 power cord into the power outlet.
A 15 amp, 14 awg, 100V to 240V power is required with this instrument. This power cord is included.
1. Plug the heating equipment into the Model 740.
2. Switch the main power (on back of the unit) to the ON position.
3. Insert a Type J thermocouple into the port.
4. If collecting temperature data, then connect your computer to the temperature controller’s RS 485 data port.
5. Set the required temperature (set point) using the ↑ or ↓ buttons on the Watlow display. The basic instructions for operating the Watlow EZ-Zone PM PID Controller are included in this section. For complete operating instructions, please visit www.watlow.com.
6. Turn the heater switch to the ON position. The heater switch is lighted when it is active.
4.1 Set Point Temperature Instructions
1. From the home display, Press ↑ or ↓ buttons to set the temperature.

102572488 Revision A, September 2015 10
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 Home screen, hold the ↑ or ↓ buttons down for a few seconds until this message appears: Oper.
3. Press the up arrow to change to Loop.
4. Press Advance key until this message appears: Aut.
5. Use the up/down arrows to change to Yes.
6. Press the Infinity key to go back to the home page.
7. 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 90% of the setpoint value.
When the process is complete, the display should stop flashing the tUnE message.

5 Maintenance and Troubleshooting
The Model 740 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 740 exterior. The labels can be cleaned with isopropyl alcohol. Do not use water or water-based solutions to clean the labels.
Ensure the unit is unplugged before cleaning.
Soap should be used sparingly to keep moisture from entering the inside of the case.
• 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. Set point Temperature not set properly.
Turn the Heater Switch to ON position. Set the set point temperature.
Heater Switch does not light when set point 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 a loose connection. Thermocouple is not working.
Firmly push the thermocouple into the jack. Replace thermocouple.
