Ref #: GXW5.1HOT

Title: GXW5.1

Classification: Technical Note

Symptom: Fan is not operating when Amplifier appears hot.

Solution: Check below

Remedy: None

The fan operation on this unit requires two conditions to be OK
(HIGH). One is the rise of the temperature at the heat sink and at
the same instances a presence of a signal (Voltage) at the output.
The fan will not operate only on the Temperature Status and nor does
it on the Voltage presence at the outputs. Rather, both conditions
have to be present in order for the Fan to work. Technicians may
assume this a problem, when it isn't.

Pin 26 and 31 need the following conditions met.

Pin 26 Pin 31 Fan
L L None
H L None
