Power Interface Board (Pib) Dc Voltage - Jandy AquaPure Workbook

This test confirms that the Power Inter-
face Board (PIB) is taking the AC Volt-
age from the Transformer and converting
it to DC Voltage.
First Test:
Set the meter to 200 DCV or
higher. Put the leads on the
Common & +12 VDC test
points. The voltage should be
between 11.8 to 12.2.
If the voltage is outside the
above range, replace the PIB.
Second Test:
Set the meter to 200 DCV or
higher. Put the leads on the
Common & +5 VDC test points.
The voltage should be between
4.8 to 5.2.
If the voltage is outside the
above range, replace the PIB.
