If the relay action is set to LO W and the hysteresis mode is EDGE,
the relay will turn ON at [(RELAY SET POINT)], and will turn OFF at
[RELAY SET POINT+ (hysteresis value)].
CAUTION :
Setting any hysteresis value to zero may cause jitter and possibly
damage the relay(s).
D. pH RELAYS
There are two
independent relay
channels for pH display
which has
independen t
set point and control
action
(HIGH or LOW,
see figure 1.). The
hysteresis mode (center
or edge, see figure 1
. )
and hysteresis value will
be used by
both pH
relays.
The action of the pH
relays is dependent on
set point, relay control
action (HIGH or LOW),
hysteresis mode (Center
or Edge), hysteresis
Value and the current
pH display (See figure 1.)
