MAIN MENU
The sensors and controls in the main menu vary with your Analyzer part number and sensors
and pumps that you enable or disable.
The main menu groups sensors with the relays that they control.
Where are Sensors and Relays Connected?
You may modify the names of sensors and outputs but the Analyzer tags each input with a
letter
A
to
Z
and each output with a number
1
to
9
representing where each is wired.
Inputs
A
,
B
and
G
and
O
to
V
have fixed wiring terminals on the upper Analyzer board.
G
is a temperature sensor
Inputs
O
to
V
may be individually selected to be digital inputs.
Terminals for outputs
1
to
5
are located on the lower board.
They are ON/OFF power relays that switch 120 or 230VAC.
Terminals for outputs
6
to
9
are also located on the lower circuit board.
They are electronic switches used for frequency control.
Inputs
C-D
and
E-F
are used for plug-in sensor cards which add optional 4-20mA inputs &
outputs to the Analyzer. The pH sensor and NH3 sensor are wired into the OP card as inputs
C-D, respectively.
Sensor inputs
H to N
and meter/contact set inputs
W to Z
don’t physically exist in the
Analyzer and are used to calculate other advanced Analyzer functions.
