Page 5: Chapter 1 - Safety Instructions
The safety alert symbol ! precedes a general CAUTION statement. Safety Notices ! CAUTION: The Watlow F4T Manuals are written by the manufacturer, Watlow, for a wide variety of applications and configurations. Not all features or functions are applicable. Only the capabilities of model F4T1L2EAA2D7030 are applicable. -
Page 7: Chapter 2 - Using Cascade Control
Without Cascade Control the Part Temperature will take longer to stabilize due to its thermal mass as shown in the graphs below.

Page 9: Part Control Vs. Air Temperature Control
The F4T is configured at the factory to allow the Air Temperature to deviate no more than +15°C or –15°C from the Part Temperature set point. This means if the set point is 85°C, the Air Temperature could go as high as 100°C if the Part Temperature lagged sufficiently during a heat... -
Page 10: Air Control Mode
This function is similar to turning Air Control ON. If you leave Air Control OFF and turn Simple Set Point Enable ON, the F4T will attempt to control the temperature at the Air Sensor. However, the Guaranteed Soak and Wait For Process will be controlled by the Part Sensor. -
Page 11: Data Logging
Chapter 2 – Using Cascade Control Data Logging Logged Parameters You can select the parameters which get logged. TestEquity has pre-configured the controller to log the Set Point, Inner Process Value (air temperature sensor), and Outer Process Value (part temperature sensor). -

Chapter 3 – Communications Chapter 3 – Communications Ethernet Parameters This section describes how to configure the Ethernet Communications settings in the F4T controller. Changing Ethernet Parameters 1. Press the Menu, Settings and Network buttons, in that order. 2. Under Communications Channels press Ethernet. -

• Parity: [None] Must match the parity of your computer’s serial port and software. • Display Units: °F, °C [configured by TestEquity for °C] • Modbus Word Order: [Low High], High Low Modbus allows a user to select the word order of two 16-bit words in floating point values. -
Page 15: Common Modbus Registers
Common Modbus Registers F4T Mode The following registers are applicable in the F4T Mode (Data Map 1). These are the most common registers that would need to be used in an automation environment. Some of these registers are different from F4T controllers that do not have Cascade Control. - Page 16 0 to 40 Current Step 16590 (R) 0 to 50 Step Type 16592 (R) Soak = 87 Wait For = 1542 Instant Change = 1927 Ramp Time = 1928 Ramp Rate = 81 End = 27 Page 16 TestEquity F4T Controller...

Page 20: Gpib And Ethernet Modbus Interface Converters (Optional)
F4T's native Ethernet interface is if you wanted to program using simple ASCII commands instead of Modbus packets. NOTES: Composer software will only work with the native F4T Ethernet interface and Data Map 1, not the TE-1056 Serial Modbus-to-Ethernet Converter. The F4T’s native Ethernet Interface accepts both Modbus and SCPI commands. You do not need the TE-1056 Serial Modbus-to-Ethernet Converter if you want to send SCPI commands directly to the F4T’s native Ethernet Interface! F4T native SCPI commands will... -
Page 21: Programming Syntax For The F4T Controller
Chapter 3 – Communications Programming Syntax for the F4T Controller The following applies if the F4T serial interface is configured for Data Map 1. This only applies for programming through the GPIB or Ethernet Modbus converters. The F4T Controller uses two consecutive register to control a value or to read back a process variable. - Page 22 Off = 62 Startup = 88 Set Point = 85 Both = 13 Ramp Scale (Temp. °/Minutes) W 2956, 57 Ramp Scale (Temp. °/Hours) W 2956, 39 Ramp Rate (Temperature) W 4058, value (0 to 99,999) Page 22 TestEquity F4T Controller...
