Relay action, relay set point and hysteresis value:
Relay Action
Effective RELAY-ON Set Point
Effective RELAY-OFF Set Point
HI
S.P. + (1/2 H.V)
S.P. – (1/2 H.V)
LOW
S.P. – (1/2 H.V)
S.P. + (1/2 H.V.)
S.P. = Relay Set point
H.V. = Hysteresis value (Dead Band)
If the relay action is set to
HIGH
, the relay will turn
ON
at (Set Point +1/2
Hysteresis ), and will turn
OFF
at (Set Point -1/2 Hysteresis ).
If the relay action is set to
LOW
, the relay will turn
ON
at (Set Point -1/2
Hysteresis ), and will turn
OFF
at (Set Point +1/2 Hysteresis ).
There are two Independent relays the user can bind to the
Conductivity
or
Resistivity mode
. The user can only bind the two relays to one reading mode at a
time. The user can change this anytime by changing option at the
setting mode
.
