This menu is used to set ORP control parameters
including set point, differential, high and low alarms
plus a feed limit timer. (This menu choice will be
present only if you have the ORP control option, see
model numbering on page 3.)
ORP Trip
- The ORP reading value that will activate
the ORP relay
ORP Diff
- Normally a falling trip point, the ORP relay
comes on if ORP falls below the trip point and goes off
when it rises above the trip point plus the differential.
The differential may be made positive by pressing
the DECIMAL key when changing differential setting.
When the differential is positive, the Trip Point changes
from falling to rising.
High Alarm Setting -
Setting for a high ORP alarm
condition.
Low Alarm Setting
- Setting for a low ORP alarm
condition.
ORP Limit Timer
- The ORP limit timer is set in hours
and minutes. If the unit calls for feed longer than the
limit timer is set for, an alarm is given and the ORP
feed is stopped. Maximum value is 9 hours and 59
minutes. A setting of zero disables the timer.
After entering a new numerical value hit the ENTER
key to accept value and advance.
