Sensor Setup
Aux, E-Aux Conductivity, DO, ORP, pH, and temperature system set points, control
mode (set point or PID/PWM), alarm and sensor system relays are configured in
the Sensor Setup menu. In addition, the salinity system is enabled in this menu.
All networked instrument relays can be configured for control and alarm output
devices - see Use AquaManager to configure system inputs and outputs - page 146.
Enabled relays energize when a control or alarm system is active. Alarm notifications
can be sent via email or cell phone (SMS messaging) - page 96.
Notes:
-
For normal operation, the 5200A must be at the Run Screen. Alarm func-
tionality (alarm emails, activation of assigned alarm relays, alarm icons,
and buzzer) is suspended when 5200A is not at the Run Screen.
-
Sensor system must be enabled in order to display values at Run Screen.
Control and/or alarm relays will not energize regardless of value if the
sensor system is disabled.
-
There is a 30 second delay at power up before control, timer, and alarm systems
become active.
-
There is a 30 second sensor system hold off when sensor configuration is
changed. See 30 Second Sensor System Hold Off - page 131.
-
Calibrate sensor prior to use. See Calibration - page 75.
-
“Over” and “Under” readings at sensor display indicate a measurement value
outside the operating range of the 5200A.
-
Control and Alarm functions, including relays, are suspended when a sensor
reading is “Over” or “Under.”
-
“Over” and “Under” readings most likely indicate that the sensor needs to be
serviced or replaced, or a bad probe/cable connection exists.
-
See Menu Maps - page 226 for system defaults and ranges.
-
One relay can be assigned to multiple systems. It is essential that the relay
configuration be verified in order to avoid conflict of operation of wired relay
devices. Assigning one relay to multiple systems can result in invalid operation.

Configure Aux and E-Aux non digital, Conductivity, DO, ORP and pH systems to
control and alarm at user configured values to best manage your aquatic system.
Sensors, aux and E-Aux analog devices report values to the 5200A. Wire and con-
figure peripheral devices (outputs) to turn on and off in order to maintain certain
water conditions as close to the setpoint as possible. 5200A instruments have three
control modes. They are Set Point control which is described starting on page 150,
PID/PWM and PID 4/20mA control which are described starting on page 176.
Control mode configuration determines how a 5X00 instrument maintains a water
parameter as close to setpoint as possible. System menu options change based on
the control mode.
Follow page links below to see examples of instrument menus displayed for differ-
ent control mode:
- E-Aux 4/20mA system Set point control example - page 164;
-Aux and E-Aux digital - page 162. (Digital inputs do not have a control mode
selection.);
-Temperature E-Aux Set point control mode example - page 165;
-DO Set point control mode example - page 171;
-PID/PWM and PID 4/20mA control mode example - page 176;
Notes:
-
Aux digital systems do not have set point or PID/PWM control modes. See
page 157 for complete aux digital configuration information.
-
Sensor Setup menu selections change based on the configured control mode
