Calibration Logs
Calibration logs store sensor calibration data. Calibration logs are date and time
stamped and contain sensor and calibration information for completed calibra-
tions.
Certain calibration data is not available at the 5X00. Use AquaManager to view and
save calibration data to a PC. In addition to sensor system, time, date, and calibra-
tion method, AquaManager calibration logs include user input 1, user input 2, and
the original and new slope/offset information when applicable.
Event Logs
Control, Alarm, and Timer relays assigned to 5X00 systems create events when they
energize and de-energize. In addition, AC power fail, ethernet failure to initialize
errors and mode network failures create events. These events are recorded in the
Event log. Events identify the 5X00 system, are time stamped, and record relay on
and off times (if applicable). The General Alarm does not create an event or control
message unless a General Alarm relay is enabled.
Note:
- Enable event logging in the System menu. See Event Logging - page 112 for
additional information.
Sensor Logs
Enabled systems record sensor data based on data logging menu configuration.
Sensor logs identify sensor system, are date and time stamped, and record sensor
value at user configured intervals.
Notes:
- Data logging must be enabled in the System Menu. See Data Logging menu-
page 110 for additional information.
Svr Hold softkey Button
When servicing sensors or doing tank maintenance, it may be necessary to shut
off all systems (including relays) because sensor values will not be accurate. Press
at Run Screen to enter Service Hold menu. When in Service hold, all relays
are de-energized until the Service Hold time expires. The Service Hold time is user
selectable. Enable and configure service hold time at Menus → System→Service
