f. ORP CONTROL SETTING
1.
RELAY3
- The control action for this
relay is changeable, you can choose
“
HI
”-action or “
LO
” action. (In HI-
action the relay will turn
ON
if the
ORP is greater than the RELAY3 set
point, in LO-action the relay will turn
ON
if the ORP is less than the
RELAY3 set point, which is modified
by the hysteresis value and hysteresis
mode.)(See chapter
V. CONTROLLING THE RELAYS
.) Use [
]
and [
/
pH-Recal
.] to change the RELAY3 action then press [
] to
save. After you select the RELAY3 action you can now select the
RELAY3 set point. Use [
] and [
/
pH-Recal
.] keys to change the
blinking digit; use the [
MODE/-
] key to select another digit and the
[
]
key to save the new set point.
2.
RELAY4
- The control action for this relay is changeable, you
can choose “
HI
”-action or “
LO
” action. (In HI-action the relay will
turn
ON
if the ORP is greater than the RELAY4 set point, in LO-
action the relay will turn
ON
if the ORP is less than the RELAY4 set
point, which is modified by the hysteresis value and hysteresis
mode.)(See chapter
V. CONTROLLING THE RELAYS
.) Use [
]
and [
/
pH-Recal
.] to change the RELAY4 action then press [
]
to
save. After you select the RELAY4 action you can now select the
RELAY4 set point. Use [
] and [
/
pH-Recal
.] keys to change the
blinking digit; use the [
MODE/-
] key to select another digit and the
[
]
key to save the new set point.
3. HYSTERESIS
(
mode
) -this is the hysteresis mode for ORP
RELAY3 and ORP RELAY4. You can choose “
CENTER
” or
“
EDGE
”. (See chapter
V
.
CONTROLLING THE RELAYS
.)
4.
HYSTERESIS
(
value
) - this is the actual value of the hysteresis.
You can change this value from 1
(Don’t set to 0 mV)
to 999 AmV or
RmV.
( See chapter V. CONTROLLING THE RELAYS .)
