5. Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s 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 GPI
and the LED’s are described in sections 5.1 and 5.2. The GYDA controller is described in a separate user
manual.
5.1 GPI ALARM – Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI outputs are open
collector outputs, sinking to ground when an alarm is triggered. The GPI connector is shown in figure 7.
