Aux Relay Analog
When enabled, the Aux analog relay energizes when either the control/alarm high
OR the control/alarm low value is processed by the 5400. Aux relay energizes aer
the congured aux hold o time. When alarms are disabled and as long as value
≤ control/alarm low value OR value ≥ control/alarm high value is processed by
the 5400, the relay remains energized including when menus are entered. Relay
de-energizes when a value > control/alarm low value OR value < control/alarm
high value is processed by the 5400 regardless if alarms are enabled. If alarms
are enabled, the relay also de-energizes when one of the four front panel sokeys
is pressed. Pressing one of the sokeys resets the
alarm system. e Alarm system becomes active again if, aer the aux hold o
period, the alarm condition still exists.
Aux analog events (event log) are identied by aux number, relay state (on/o), and
report “alarm high” or “alarm low” condition regardless if alarms are enabled.
AquaManager identies Aux analog events as control or alarm based on node
conguration.

Notes:
Control/alarm high value must be ≤ Max value. Control/alarm low -
value must be ≥ Min value. Min & Max values are congured in Menus
→ System → Congure Aux →Aux 1-2→Min/Max menu.
Do not enable aux analog alarms when the sensor is in the control/alarm -
condition. Enabling aux analog alarms when sensor is in control/alarm
condition can result in aux system not properly processing existing alarm
condition.
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 deter-
mined based on the readings from the sensor. Conductivity values >10,000 µS are
displayed in mS. See Set Points, Control, and Alarms - page 128 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 145.
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 - 194 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.
In the timed mode, an energized control relay is energized for the congured dose
time, regardless if the sensor value has returned to the set point value. Aer the
dose time expires, the control relay de-energizes for the congured dwell time.
