detected.
With the unit switched OFF (at least for 4 minutes), perform the following tests:
1. Check that connectors X56 and X57 are well connected: connect it and verify if
the error is still present.
2. With connector X57 CONNECTED, using a multimeter, perform the measures
listed in the following table:
Parameter

3. With the connector X57 DISCONNECTED perform the measures (connector
side) listed in the following table:
Parameter
Connection
Value
Feedback mA
X57-4(GND) and X57-1
326 Ω ÷ 334 Ω
