Menu structure
The configuration and calibration functions are arranged in function groups.
• In the setup mode, select a function group with the PLUS and MINUS keys.
• In the function group itself, switch from function to function with the ENTER key.
• 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.
• Press the PLUS and MINUS keys simultaneously (Escape function) to exit programming
(return to the main menu).
• Press the PLUS and MINUS keys simultaneously again to switch to the measuring mode.
If a modified setting is not confirmed by pressing ENTER, the old setting is retained.
An overview of the menu structure is provided in the Appendix to these Operating
Instructions.

Hold function: "freeze" the outputs
In both the setup mode and during calibration, the current output can be "frozen" (factory
setting), i.e. 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 during a hold.
• Hold settings can be found in the "Service" function group.
• During a hold, all contacts assume a quiescent state.
• An active hold has priority over all other automatic functions.
• With every hold, the I-component of the controller is set to "0".
• Any alarm delay is reset to "0".
• This function can also be activated externally via the hold input (see Wiring diagram;
binary input 1).
• A manual hold (field S3) remains active even after a power failure.
