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 TS1 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.
7 Main Printed Circuit Board
The Main printed Circuit Board controls, supplies power to, and or receives signals from the various
electronic and electrical components within the System. The Main Printed Circuit Board is clearly
marked indicating connection points for each component along with 12 VDC polarity of each component
receiving power from it.
The Main Printed Circuit Board also incorporates LED visual indications of the components it controls.
When the respective LED is illuminated the controlled devise is receiving power and therefore is
functioning. For example, when the Booster Pump is operating the "BP" CONTROL STATUS LED at
the Main Printed Circuit Board will illuminate.
Always troubleshoot and track voltage at the end of the line first and work your way up to the start of
the line. For example, when determining why a Booster Pump is not operating first check the voltage at
the Booster Pump and work your way back to each component checking for voltage across each
connection and each component.
8 Step Down Transformer used in 3 phase systems only
The Step Down Transformer is not required for single phase systems. It is only required for three phase
systems. It accepts the high voltage operating power at its primary and steps the voltage down to 115
VAC out of the transformer's secondary for primary input power to the 12 VDC Power Supply.
