Testing a System with Power

LOW VOLTAGE

At Balboa, it’s been our experience that the majority of the
problems associated with electronic control systems are due to
low voltage.

BROWN OUTS

“Brown outs” can have an effect on the spa’s operation in a
variety of ways. The control panel may go blank, have scrambled
messages on the LCD, or only a few features will function.

CHECKING THE SYSTEM POWER INPUT FUSE

WARNING

THESE PROCEDURES ARE PERFORMED

WHILE THE SYSTEM IS POWERED UP AND

RUNNING UNDER PEAK LOADS.

Measure between the white TB1 terminal and power input

UÊ

fuse. You should see 120 volts.
If the system is equipped with the additional power input

UÊ

fuse, measure additional power input fuse in the same
manner. You should also see 120 volts.

If the system is getting the proper

voltage at TB1, but still doesn’t operate,

then test for a blown power input fuse.

(See section: Testing Pump Fuses for Damage)

BP500 Board, 240V Setup

TB1 Marking

on Board

If your system uses 240V peripheral devices (below):

Measure between the

UÊ

red TB1 terminal and power input

fuse. You should see 240 volts. If the system is equipped
with the additional F6 power input fuse, measure F6 in the
same manner. You should also see 240 volts.
If you determine that there is no voltage at one or both

UÊ

locations, then the system power input fuse(s) need to be
replaced. Only use a fuse of the same type and amp rating
when you replace any fuse.

NOTE FOR ALL SYSTEMS:

UÊ

In each situation, the most

likely reason for the system power input fuse to blow is a
pump problem. However, on occasion, a blower problem
may also cause this fuse to blow if a 10A blower fuse is not
built in.

Once the power input fuse has been changed

Probe the red wire and the white neutral wire. Again,

UÊ

voltage must be between 108 and 132 V.
Check the voltage between the black and red wires again.

UÊ

Acceptable voltage range is between 216 and 264 V.
