7.3 Check Point Voltages

7.3.1 User Interface - Status LEDs

The LED within the start key (ON/OFF button) on the User Interface is used to signal the status of the
Voluson E-Series system.
The following states are implemented:

7.3.2 Power Supply (RSP) Status LEDs

On the backside of the ATX board near the fans 3 green status LEDs are mounted. These LEDs are used for
signaling the status of the Power Supply (RSP).
LED 3
LED 4
LED 5

Orange System in standby mode.
Green System in normal operation mode.
FPGA_CONF_DONE = low
blinking
IF-FPGA not initialized -> probably FrontEnd (RFM board) or Power Supply
Orange <=> Green
(RSP) issue
NO light System is switched OFF (circuit breaker)
NO light probably Power Supply (RSP) defect
Figure 7-6 check green LEDs inside RSP
Off: 12V_FE off
On: 12V_FE on
Off: FPGA_CONF_DONE = low
On: FPGA_CONF_DONE = high
Off: ATX supply off
On: ATX supply on
