COMMODORE 1 15V
SOLID STATE CONTROL
BOARD (DC CIRCUIT)
The PC Control Board converts aiter-
nating current (AC) to direct current
(DC) for the traverse drive motor and
clutch solenoid.
A 2 amp sio-blow ceramic fuse is in-
stalled in the motor circuit to protect
the circuit board and motor in the event
an overload condition occurs.
NOTE: Always use the same type and
size fuse for replacement.
NOT RUN, CHECK THE
1. Check continuity (use ohmmeter) of
slow-blow fuse.
for short circuit in system or faulty
motor. If this does not correct prob-
lem the PC Control Board may be
faulty.

Aug power cord into properly grounded
Use AC volt meter check Input volt-
to
age at terminals AC and AC on PC
Board. Voltage should be 115V (on
5 volt models) and 230V (on 230 volt
11
models). Use DC volt meter
DC output voltage at terminals A+
and With the speed control knob
A-.
set at MAX DC volts should be 95
(4)
VDC 10%. if there is "0" voltage
or the voltage does not remain constant,
this is an indication that the circuit
board is faulty. Replace as required.
TO TEST T R A V I R S I
To test for around or short circuit, first
disconnect machine power cord from
tinuity), the armature is grounded,
To check for shorted armature, use
ohmmeter measure the resistance
to
between the motor leads. if resistance
is 5 ohms or less, the armature is
short circuited; replace gear motor.

to check
The fuse is located in-line near the
clutch actuator coil.
1 . Check clutch switch (use ohmmeter)
for continuity.
2. Check in-line 1 amp fuse. If fuse
blows after replacing, the coil is
faulty. Replace as required.
3. Use a DC volt meter
voltage to clutch coil at terminals F+
and F- on Control Board. The DC
voltage should be 95 VDC
the voltage does not remain constant,
the circuit board is faulty. Replace
as required.
