Menu structure
The configuration and calibration functions
are arranged in a menu structure by function
groups.
The function groups are selected in the setup
mode with the PLUS and MINUS keys. The
ENTER key is used to move from one function
to the next within a function group. The PLUS
and MINUS keys are used for option selection
and editing. Selections must be confirmed by
pressing the ENTER key. This also moves the
cursor to the next function.
Pressing the PLUS and MINUS keys at the
same time terminates programming (return to
main menu).
Note:
•If a change is made but not
confirmed by pressing the ENTER
key, the previous setting is
retained.
•See the appendix of these
operating instructions for an
overview of the Liquisys M
CLM 223 F menu structure.
HOLD function: »freezing« the outputs
The current output can be »frozen«in the
setup mode and during calibration, i.e. the
last current value (resp. the in field S3 defined
value) is constantly output. The display shows
the »HOLD«message (see chapter 5.8, p. 34
for hold settings).
•During HOLD in the automatic mode the
contacts will go to the idle position
(if factory settings are active).
•At CC, timer and external HOLD HOLD
always is active. Adjustments in the fields
S2 and S3 will be ignored.
•An alarm delay will be reset to »0«.
•This function can also be activated
externally via the HOLD input
(see connection diagram in Fig. 3.4,
digital input 1).
•The manual HOLD (field S3) also remains
active after a power failure.
