6 Module status

The status of the module can be monitored in three ways.

1. GYDA System Controller (optional).

2. LEDs at the front of the sub-rack.

LEDs are mounted on the module itself, whereas the GYDA System Controller is a separate

module giving detailed information on the card status. The functions of the LEDs are

described in sections 5.1. The GYDA controller is described in a separate user manual

The status of the module can be easily monitored visually by the LED’s at the front of the

module. The LED’s are visible through the front panel. The LED on top tells if the DA-AA is

ok or not (green LED means ok – red is alarm). The second LED gives the input signal

status.

The DA-AA has 2 LEDs each showing a status corresponding.
