Power for the analog module should be separate from the display unit's power supply and it should be turned on at least 1 second ahead. When turning the LT unit ON, first supply the module with power for 1 second or longer before you turn ON the LT unit. The display unit may not operate correctly if it is restarted too quickly.
When using the analog module (set up with 4 to 20 mA), and signals are less than 4 mA or greater than 20 mA, an abnormal data error message displays. In this scenario, inputs retain their previous values before the error.
Internal communication between the display unit and TM3 module may experience a maximum delay of scan time + 20 milliseconds.
In addition, because the TM3 module (hardware) also has a delay, to calculate the actual delay time for inputs and outputs, also add the TM3 module delay time.
The number of TM3 modules that can be connected
The number of TM3 modules that can be connected differs depending on the display unit or TM3 module type used. Please refer to the following table for details.
