Hold function: “freezing” of outputs
The current output is “frozen” in the setup mode and during quick calibration, i.e. the last current
value is constantly output. The display shows the “HOLD” message. During automatic operation,
all contacts will go to their normal positions. Any alarm delay accumulated will be reset to “0”.
This function can also be activated externally via a contact input (see chapter 4.4, “Connection”).
Note:
If the hold function is to remain active even after a power failure, the hold contact input
is to be used.

Operation example
Note:
Cf. menu structure on fold-out back page.
Supposing the limit value for relay 2 were to be set to 120 FNU as the switching point using the
min. function, you would proceed as follows:
Select the “Setup Code” field (S.Cd = Setup Code).
Enter code 22 to access the configuration mode.
Confirm the code.
The instrument is now in setup mode, and the first function
group, “SYS” (system configuration), is selected.
The hold function is active.
