GENERAL DESCRIPTION & INTENDED USE
DATA LOGGER & EVENT
LOGGER
• The controller automatically logs the process control information in
an interval log, and various event alarms and errors in an event log
• Logged data can be retrieved and events visualized on the screen, in
Log Recall menu
• Interval logs store up to 8600 records, maximum number is 100.
• Logging interval can be set in the General settings menu
• The logged data includes: pH (or ORP) and temperature measurements,
last calibration data, setup configuration, event data, event code, start
date and time, end date and time, previous value, mV value of the
parameter
• Event log can store up to 100 records of events, alarms, errors related
data
• Log files can be uploaded to a USB flash drive via USB-C port
MANUAL MODE
• Used to exercise relays and analog outputs
• Useful for setting up the system, filling up the pump circuit, checking the
cabling wiring, and during general maintenance
• Default option when the industrial application requires manual input
• As a safety feature, a 60-minutes timeout is implemented before relays
turn off and analog outputs return to their previous value before entering
Manual Mode
CALIBRATION
• pH single point process calibration, or calibration up to three-points,
using two buffer sets:
• Hanna Instruments
–
1.68, 4.01, 7.01, 10.01, 12.45 pH
• NIST
–
1.68, 4.01, 6.86, 9.18, 12.45 pH
• ORP calibration using a single point process calibration
• Last calibration is stored in the probe and can be visualized in the
Cal Data window
• Calibration reminder can be scheduled (1 to 99 days, Off)
Note:
As a safety feature, when in Setup or Calibration mode, without making any changes or
pressing any key, the controller will return to Measure mode and restart control.
