- 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 conguration be veried in order to avoid conict of operation
of wired relay devices. If not congured 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
Congure control and alarm low and high values, control and alarm relays and hold
o time in the Sensor Setup Menu. Read Control Mode and Alarms - page 132
before conguring the Aux systems.
AquaManager identies Aux analog events as control or alarm based on node
conguration.
Directions to Congure 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-
gure Aux →Input Type - page 101 .
3. Enter Aux 1-6 in Sensor Setup menu
Menus → System → Sensor Setup→Aux 1-2
4. Congure Control Mode - page 132.

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
e conductivity system operates in one of four ranges. e ranges are: 0-200
µS, 0-2000 µS, 0-20mS, and 0-200mS. e 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
conguring conductivity system.
Notes:
- When conductivity is enabled, salinity is ALWAYS calculated by the
conductivity sensor value. is value is used to calculate the DO mg/L
value. e 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 dened 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 conguration.
Timed and Normal Control
Conductivity high and low control can operate in two dierent modes, normal or
timed. In the normal mode, control relays are energized until the set point value
is reached. e normal mode can be used for either low control, high control, or
both. For normal control, congure the dose up/dose down to 0. e dwell time
will be ignored.
