2. REMOTE CONTROL TOUCH PANEL***
Refer to SYSTEM TOUCH SCREEN for
similar troubleshooting.
3. SOFT MOTOR STARTER***
The Soft Motor Starter, used only in AC (Alternating
Current) Single Phase systems, reduces the initial
startup amperes required to start the motor and in turn
allows a smaller sized KW generator to start the system.
Starting amperage is reduced by 40% with the Soft Start
installed. The maximum design rated Horse Power that
the Soft Motor Starter will accept is 3 Horse Power.
Should the Soft Motor Starter fail to function refer to
wiring diagrams in Section 4. Check all wiring for correct
position and tight connection. Check wiring from the
incoming power, through the Soft Motor Starter, and at
the Electric Motor that it is controlling.
Owner or Installer Supplied Items that are Not Numbered
or shown on the Piping and Interconnect Diagrams but
are included in the Electrical Diagrams in Section 4:
FRESH WATER TANK LOW LEVEL SWITCH **:
This owner/installer supplied Fresh Water Tank Low Level
Switch provides an optional feature to the System Control
Logic that works in conjunction with the Automatic Fresh
Water Flush option.
When installed and connected to the Main Printed Circuit
Board, the Fresh Water Tank Low Level Switch must be
connected as a N.O. (Normally Open) 1PST (One Pole
Single Throw) switch.
When the Fresh Water Tank is empty the switch is Open.
As water rises a few inches in the tank the switch Closes.
This informs the System Control Logic that there is
sufficient Fresh Water to perform the Automatic Fresh
Water Flush Cycle.
If this Switch is Open, indicating that the Fresh Water
Tank is empty the Fresh Water Flush cycle will be
automatically canceled by the System Control Logic.
FRESH WATER TANK HIGH LEVEL SWITCH **:
This owner/installer supplied Fresh Water Tank High Level
Switch provides an optional feature to the System Control
Logic that allows the System to shut off automatically
when the Fresh Water Tank is full, when the System is
operated in the Automatic mode. Additionally, the System
will not start in the Automatic mode when the Fresh
Water Tank High Level Switch signals the System Control
Logic that the Fresh Water Tank is full.
Aqua Matic Modular 450-1800
When installed and connected to the Main Printed Circuit
Board, the Fresh Water Tank High Level Switch must be
connected as a N.C. (Normally Closed) 1PST (One Pole
Single Throw) switch.
When the Fresh Water Tank is several inches below
the full mark the switch is Closed. As water rises and
reaches the top of the full mark the switch Opens. This
informs the System Control Logic that the Fresh Water
Tank is full, the System will shut down if operating in
the Automatic mode, and the System will not start in the
Automatic mode.
If operation of the System is desired when the Fresh
Water Tank Switch signals the System Control Logic that
the Fresh Water Tank is full then the System may be
operated in the Manual mode.
4. ELECTRICAL CHASSIS
The Electrical Control Box contains all of the Electronic
and Electrical circuits and components. Troubleshooting
of major components is described below:
a. Fuses
b. High Pressure Pump Contactor
c. Booster Pump Contactor
d. Fresh Water Flush Relay
e. Customer Supplied Alarm
f. 12 VDC Power Supply
g. Main Printed Circuit Board
h. Step Down Transfer used in 3 phase
systems only
Additional external devices connected to the Main Printed
Circuit Board:
a. UV Sterilizer
b. 3-Way Product Water Diversion Solenoid Valve
1 Fuses
There are 2 fuses protecting the 12 VDC Power Supply
primary circuit. Should one or both of these fuses fail
this is an indication of high current draw from any one
of several 12 VDC devices in the System. Devices
powered from the 12 VDC produced by the 12 VDC
Power Supply include:
a. Main Printed Circuit Board/Main Touch Screen
b. Remote Touch Screen
c. High Pressure Pump Contactor
d. Booster Pump Contactor
