Introduction:

This application note will address the wiring set up of a pressure transducer with a

FRENIC-MEGA G2 drive, and parameter settings, to operate under PID control using a

4-20mA feedback signal.

Wiring:

The pressure regulator sensor with a 4-20mA output is to be connected as follows:

1) Connect drive terminal PLC (24VDC) to the sensor's red lead or terminal 1 (+)

2) Connect drive terminal C1 (+) to the sensor's black lead or terminal 2 (-)

3) Connect a wire jumper between drive terminals 11 and CM

Page 2 Function Codes The following table displays the parameters that need to be set in the drive to operate PID control using the keypad to set the command (target) value, and 4-20mA feedback signal. Code Setting Description 1 - for normal operation (typically PID Control Mode used) 2 - for inverse operation...
Page 3 Entering the Set value To enter the set value, the setting the PID loop is to maintain, for the above settings you will enter the set value through the keypad. Utilize the LEFT and UP arrow keys to set the value. Pressing LEFT will allow you to move the cursor to the left most digit for faster setting.
