Conductivity
Menus →Sensor Setup→Conductivity
The conductivity system operates in one of four ranges. The ranges are: 0-200 µS,
0-2000 µS, 0-20mS, and 0-200mS. The conductivity range is automatically deter-
mined based on the readings from the sensor. Conductivity values >10,000 µS are
displayed in mS.
Notes:
-
When conductivity is enabled, salinity is ALWAYS calculated by the conduc-
tivity sensor value. This value is used to calculate the DO mg/L value. The
salinity value is displayed at the Run Screen when salinity is enabled. See
Salinity
- page 176.
-
Disabling conductivity requires that a ppt value be user defined in the 5200A
DO sensor menu.
-
5561 probe/cable users should ALWAYS disable the conductivity system since
there is no conductivity sensor to accurately compute a salinity value.
-
Conductivity set points do not self adjust based on the range of the sensor.
See Menu Maps - page 226 for default configuration.
Temperature Compensation
Conductivity values vary with temperature. Conductivity values are normally
compensated to 25°C. An adjustment of approximately 1.91% per °C is common.
Enter “0.00%” at the temperature compensation menu to disable temperature com-
pensation. “*” is displayed next to a conductivity value at the Run Screen to indicate
temperature compensation is enabled.
Configure Conductivity System
Before configuring Conductivity system 1) See - “Use AquaManager to configure
system inputs and outputs” - page 146. AND 2) See Control modes [Set point
Control Mode and Alarms - page 150 (Conductivity set point control mode can
operate in normal or timed mode - page 153) and PID control mode - 155.]
1. Connect Probe assembly - page 60.
2. Wire relay output device(s) to local instrument, or any networked 5X00
instrument - page 46.
AND/OR
2. Wire relay output(s) device to REM - see IOEM/REM Safety and Installa-
tion guide>Chapter 3>Step 4>Wire REM Relay Outputs. Wire any output
devices to be used for system.
3. Enter Conductivity Sensor Setup menu
Menus → System → Sensor Setup →

4. Use

to scroll and highlight submenus.
5. Press
to select.
6. Enable and configure submenus. Configure control and alarm relay(s)
using AquaManager - see page 146.
7. Optional - Configure digital 4/20mA output - page 178.
8. Press
to save configuration and return to Run Screen.
9. Test system output device(s) at→System→Service→Output Test - page 141
or create an event to verify configured relay(s) energize.
Notes:
-
It is important to keep the 5200A at the Run Screen during normal opera-
tion. Alarm functionality (email alarms, activation of enabled alarm relays,
alarm icons, and buzzer) is suspended when 5200A is not at Run Screen.
-
One relay can be assigned to multiple 5200A systems. It is essential that the
relay configuration be verified in order to avoid conflict of operation of wired
relay devices. If not configured properly, assigning one relay to multiple sys-
tems can result in invalid operation of 5200A.
-
Conductivity set points are always entered in µS (multiply mS value X 1000
to obtain µS value).
-
Only whole numbers can be configured for conductivity set point, control,
and alarm values.
-
See 30 Second Sensor Hold Off - page 160.
-
Active dosing timers are reset after systemwide events. Systemwide events
de-energize relays. Example - conductivity dose up relay is configured for two
(2) minutes. Energized dose up relay de-energizes when 5200A goes into Svr
Hold. The dose up relay had been energized for 15 seconds before Svr Hold
