• Within the function, select the desired option with the PLUS and MINUS keys or edit the
settings with these keys. Then confirm with the ENTER key and continue.

Hold function: "freezing" of the outputs
During setup and calibration, the current output can be "frozen". It constantly retains its
current status. "HOLD" appears on the display. If the controller actuating variable (steady
control 4 to 20 mA) is output via current output 2, it is set to 0/4 mA in Hold.
Pay attention to the following:
• Hold settings can be found in the "Service" section.
• During Hold, all contacts will go to their normal positions.
• An active Hold has priority over all other functions.
• With every Hold, the I-component of the controller is set to zero.
• Any alarm delay is reset to "0".
• This function can also be activated externally via the Hold input (see Wiring diagram;
binary input 1).
• The manual Hold (field S3) remains active even after a power failure.
