Alignment
procedure: Idling current adjustment
Conditions:
-Connect the
DC voltmeter between TPl and TP2 and between TP3 and TP4.
-Connect a
13. 8V power supply to the 12V Battery
Power In
terminal.
-After the
power on, wait for 5 minutes before measuring to be sure of the most stable
operation.
Inspection:
-Confirm
that the idling current is 50mA :t 20mA (voltage: 33mV:t 13mV).
If the
current measured does not fall within the range specified , adjust it with the
procedure below.
Adjustment
Note: When
replacing or disconnecting a resistor, disconnect the power supply first.
After the
adjustment is complete, let the unit settle down for 10 minutes, than
double-check that the idling current is set properly.

Protection
circuit
If the
temperature inside the CA260 rises above 80 the protection circuit comes into
operation , decreasing output. At this time the protect indicator blinks. If
the temperature comes back below 80 C by natural cooling, output returns as it
was.
If the
temperature rises above 100 , the power supply circuit is shut off . Not only
does the output stop, but also the protect indicator goes out. If this happens,
it is possible that the CA260 is broken. However, even in this state, it cannot
be always said that it is broken because the unit may operate when the
temperature comes back below 80 C by natural cooling.
