3. Installation Check
* If the following conditions are not met, remedy the situation before performing start-up
operation.
3.1 Checking the Installation Status
(1) The control board is designed for indoor installation only. Ensure that the installation
location is protected from rain water and out of direct sunlight.
(2) Ensure that the control board is installed in the same room as the water treatment
equipment.
(3) Ensure that the control board is securely mounted on a vertical wall.
Figure 3.1: Maintenance space
Note 1: The door opens 24”. Ensure that the space to open and close the door + 12”or
more is available.
At least, leave adequate width for people to pass.

3.2 Checking the Wiring Status
More accurate checking of the electrical wiring is possible by referring to the “Wiring”
diagrams in the Installation Manual of the water treatment control board for boiler in addition
to the check points below.
3.2.1 Power Supply and Control Wiring
(1) Ensure that the power supply meet the 120 VAC /60 Hz single-phase specifications.
(2) Ensure that the power supply capacity (capacity and wire diameter) is correct.
(3) Ensure that a dedicated earth leakage circuit breaker with overcurrent protection is
installed in the power supply wiring.
(120 VAC rated voltage, 15 A rated current, 30 mA rated sensitivity current)
(4) Ensure that the ground terminal on the control board is grounded (D-type grounding
or better).
(5) Do not install a circuit breaker in the grounding wire.
(6) Ensure that the wiring connections are correct.
(7) Ensure that the power supply ground phase is connected to terminal S on the power
supply terminal block.
(8) Ensure that the terminals have been retightened.
(9) Ensure that the length of wires to sensors such as water level sensors, electrodes,
or flowmeters is within 164ft.
3.2.2 M-NET3 Communications
The WP2-200A is compatible with M-NET3 communications. It cannot be connected to
M-NET communications.
3.2.3 DS-NET Communications
The communication wiring must be carried out for communications with the water
treatment equipment.

(1)“Normal”lamp (green)
Lights when all equipment is normal to indicate no Alarm or Notice
has occurred in the monitored water treatment equipment.
(2) “Alarm”lamp (red)
Flashes when an Alarm has been evaluated by the control board.
The flashing lamp lights continuously when the “Select/Check”
button is pressed.
The lamp goes out when the cause of the Alarm is removed and
the equipment status returns to normal.
(3) “Notice”lamp (yellow)

and a Notice has occurred in the monitored water treatment
equipment. The flashing lamp lights continuously when the
“Select/Check”button is pressed.
The lamp goes out when the cause of the Notice is removed and
the equipment status returns to normal or the Notice is confirmed
at the monitored equipment.
(4) “Select/Check”button
Used to select the water treatment information or set item.
Used to confirm details of an Alarm or Notice.
(5)LCD screen
Sequentially displays feed water tank(*) water level,
(instantaneous flow rate), Colormetry measured values, and
Alarm/Notice history as the “Select/Check”button is pressed
(5)LCD backlight
Lights when a button is pressed. Backlighting turns off if no button
is operated for ten minutes.
Also lights when an Alarm or Notice occurs in each piece of
equipment.
(6) “↑”button
Increases the set value when making settings. (Note 1)
(7) “→”button
Moves between digits when making settings. (Note 1)
(8) “Set/OK” button
