R211
Function
Never set the switch-on point and the
pH
16.00
switch-off point to the same value!
R212
(Only the operating mode selected in A1
On value
is displayed.)
Entering a switch-off point selects either
a Max contact (switch-off point < switch-
on point) or a Min contact (switch-off
pH
16.00
point > switch-on point), thereby
R213
implementing a hysteresis that is

constantly required (see "Illustration of
the alarm and limit functions" figure).

If the alarm threshold is undershot/

If defined as a Min contact, the alarm
threshold must be < switch-off point.
