4.5.4 Hold function: “freezing” of outputsfreezes” the outputs

The current output is “frozen” in the setup mode and during calibration, i.e. the last current

value is constantly output. The display shows the “HOLD” message. In case of steady control

(4... 20 mA) on current output 2, it is set to 0/4 mA during Hold.

Note:

• Hold settings can be found in

chapter 5.5, function S2.

• During automatic operation, all

contacts will go to their normal

positions.

• An active hold has priority over all

other automatic functions.

• With every hold, the I component

of the controller is set to zero.

• A possibly accumulated alarm

delay is reset to “0".

• The hold function can also be

activated externally via the hold

input (see wiring diagram in

Fig. 3.10; digital input 1).

• The manual hold (field S3) remains

active even after a power failure.
