- Do not enable aux digital alarms when the sensor is in the control/alarm

condition. Enabling aux digital alarms when sensor is in control/alarm

condition can result in aux system not properly processing existing alarm

condition.

-

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 systems can result in invalid operation.

- Event logs are created when an aux relay energizes and de-energizes

regardless if alarms are enabled.

- Aux alarms must be enabled to trigger General Alarm.

- General Alarm may still be active even though aux system is no longer in

alarm. See aux relay information below and General Alarm - page 117.

Analog (0-1VDC, 0-5VDC, and 4-20mA)

Menus → Sensor Setup→Aux 1- 2

Configure control and alarm low and high values, control and alarm relays and hold

off time in the Sensor Setup Menu. Read Control Mode and Alarms - page 132

before configuring the Aux systems.

AquaManager identifies Aux analog events as control or alarm based on node

configuration.

Directions to Configure Aux (non temperature analog)

1. Wire Aux analog devices - page 49.

2. Select “0-1v”, “0-5v”, or “4/20ma” input type at Menus → System → Con-

figure Aux →Input Type - page 101 .

3. Enter Aux 1-6 in Sensor Setup menu

Menus → System → Sensor Setup→Aux 1-2

4. Configure Control Mode - page 132.

Menus → System → Sensor Setup → Aux 1-2 → Set Point Control

5. Use

to scroll and highlight submenus.

6.

Press

to select.

7. Configure submenus.
8. Press

to save settings and return to Run Screen.

Note:

- It is important to keep the 5200A at the Run Screen during normal

operation. Alarm functionality (email alarms, activation of enabled

alarm relays, alarm icons, and buzzer) is suspended when 5200A is

not at Run Screen.

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

determined based on the readings from the sensor. Conductivity values >10,000

µS are displayed in mS. Read Sensor Setup Control and Alarms - page 132 before

configuring conductivity system.

Notes:

- When conductivity is enabled, salinity is ALWAYS calculated by the

conductivity 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 153.

- 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 201 for default configuration.

Timed and Normal Control

Conductivity high and low control can operate in two different modes, normal or

timed. In the normal mode, control relays are energized until the set point value

is reached. The normal mode can be used for either low control, high control, or

both. For normal control, configure the dose up/dose down to 0. The dwell time

will be ignored.
