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
e. Fresh Water Flush Relay
f. Automatic Fresh Water Flush Valve Motor Actuator
g. 3-Way Product Water Diversion Valve Solenoid
h. UV Sterilizer
Troubleshooting the cause of fuse failure must include
physical inspection and electrical check of all of these
devices and all wires connected to these devices in order
to pinpoint the cause of the high current resulting in the
failure of the fuse(s).
The System can operate on one bad fuse but if both
fuses are bad the System will not operate.
2 High Pressure Pump Contactor
Should the High Pressure Pump Electric Motor fail to start
check for operating voltage at the following component
and in the following order:
a.
High Pressure Pump Electric Motor Power Leads at
the Electric Motor Junction Box
b. Main Terminal Strip power from Contactor to Motor
c. High Pressure Pump Contactor T (Terminal)
d. High Pressure Pump Contactor L (Line)
e. Main Terminal Strip power from Power
Source to Contactor
Check for Control Voltage at the Terminal Strip.
3 Booster Pump Contactor
Should the Booster Pump Electric Motor fail to start
check for operating voltage at the following component
and in the following order:
a.
Booster Pump Electric Motor Power Leads at the
Electric Motor Junction Box
b. Main Terminal Strip power from Contactor to Motor
c. Booster Pump Contactor T (Terminal)
d. Booster Pump Contactor L (Line)
e. Main Terminal Strip power from Power Source
to Contactor
Check for Control Voltage at the Terminal Strip.
4 Customer Supplied Alarm
The maximum allowable current consumption at the
customer’s supplied alarm is 1 Ampere at 12 VDC.
5 12 VDC Power Supply
The 12 VDC Power Supply provides power to:
a.
Main Printed Circuit Board/Main Touch Screen
b. Remote Touch Screen
c. High Pressure Pump Contactor
d. Booster Pump Contactor
e. Fresh Water Flush Relay
f. Automatic Fresh Water Flush Valve
g. 3-Way Product Water Diversion Valve Solenoid
h. UV Sterilizer
If the 12 VDC Power Supply is not functional then all of
the above components will not function, and the System
will not function.
Should the 12 VDC Power Supply fail, check for allowable
high voltage (64 to 264 VAC) into it and regulated low
voltage (12 VDC) out of it:
a.
Check for operating voltage at the electrical
chassis supplying voltage to the 2 fuses
b. Check for operating voltage at the input of
the 2 fuses
c. Check for operating voltage at the output of
the 2 fuses
d. Check for operating voltage at the input of the
12 VDC Power Supply
e. Check for 12 VDC at the output of the 12 VDC
Power Supply.
