Dugan Model E-3 User Guide

Power Supply

Units shipped to the USA include a 12 V, 1.5 A, 120 VAC power supply. Contact the

factory if you require a different power supply. In an emergency, the Model E-3 can

accept power supplies within the following ranges:

• 12–24 VDC, either polarity, 1.5 A

• 9–18 VAC, 1.5 A

System Reset

Hold down the channel 1 bypass button and power up the unit. Keep holding the by-

pass

button down for about three seconds until the unit finishes booting.

This System Reset command restores all parameters to factory default settings and

clears label text. This is just like zeroing a console before a show. We recommend ex-

ecuting a System Reset before starting a new installation.

The Model E-3 can execute four other power-up commands (see Appendix A: Power-

up Commands).

NOTE: If for any reason you cannot connect to a computer, power-up commands can establish

essential settings.
