Programming the Inputs
Factory programming of sensor inputs is based on
your specific order. This may include controlling
relays for pumps and solenoids. Some inputs require
further setup. The factory does not setup analog flow
or level inputs. However, this can easily be
accomplished in the field if the range of the analog
input is known. Refer to the calibration chapter
9.1 Analog and Digital Inputs
9.1.1 Enable an Analog or Digital Input:
This includes all analog and digital inputs other than
the CTFS sensor. See section 9.1.2 Enable a CTFS
Sensor.
Sensor availability in the menus is dependent upon
the installed driver cards. All sensors possible for
each of the driver cards are made available at
bootup. Sensor will probably need to be enabled
after the driver card and sensor(s) are installed, and
the controller is rebooted.
1- Press the MENU key.
2- Use the Up and Down ARROW keys to find
and point to the System choice and press the
OK button once.
3- The display will change to the System menu.
Scroll up or down through the choices until the
arrow points to Enable I/O then press OK
4- Using the arrow keys, scroll through the
disabled I/Os until the you see the input you
wish to enable
5- Press ENABLE [F3] key.
6- The input has been enabled and the display
returns to the System menu to enable
additional sensors if desired.
7- Press ESC (Escape) to exit
Note: If you enable a Serial Conductivity sensor
(CTFS), the temperature and flowswitch need to
have input letters assigned to them at that time.
This is done at the factory when CTFS sensors
are ordered with the controller. If you add a
second CTFS in the field, use the 'Enable CTFS
Sensor' instructions below.
This can result in hazardous incorrect metering
Take into consideration the sensor's run-in period
during commissioning:
There has to be adequate feed chemical in the
sample water for your application (e.g. 0.5 ppm
chlorine)
Accurate measuring and metering is only
possible if the sensor is working correctly.
It is imperative that you adhere to the sensor's
run-in periods before calibration and control.
Calculate the run in period when planning
commissioning. It may take a whole day to run in
some sensors.
Refer to the sensor's operating instructions.
