APPENDIX E
Single Amplifier Configuration with Manual Control
When operating in single amplifier mode with no serial bus controller, it is possible to provide
full control manually as shown below.
Notes:
1. If switch 2 is set to XMIT on application of prime power, the amplifier will automatically
enter the XMIT state after 3 minutes warm-up.
2. To enter the OFF state, switch 2 must be in the STBY position prior to the OFF state
being selected via switch 1.
3. The resistor values will depend on the type of LED used.
4. If specific fault indication is required, this circuit can be used. Refer to section 5.2.1 for
codes.
