AES3 I/O Relay Bypass Settings
AES3 I/O Relay Bypass
The AES3 inputs and outputs provide a relay bypass feature that, when enabled, activates in the event of a power failure or upon a deliberate command from the GUI.
In order to enable the relay bypass feature, the jumpers for each AES3 pair (A) must be in place as shown in Figure 1 below. Removing the jumpers prevents relay bypass from occurring.
