Controls:
• FORCE DC: Controls the PSU to force the usage of the DC input if usable, disregard
presence of AC. If DC is outside the usable range for the PSU, the PSU shall indicate
an alarm using the DC-fail output. If DC input voltage comes below 43 V ±2% and if
AC is usable the PSU shall take the input power from AC, disregarding a Force-DC
control input.
Note: Force DC operation on a bad DC supply PSU or Battery: Bad DC
supply is defined as a DC source where the voltage drops below 43 V for a
few milliseconds when the PSU is forced to operate on DC. In case of a
force DC command and bad DC supply the 28.5 V output voltage is al-
lowed to drop down to 27 V for a maximum of 5 second, while the PSU
automatically switches back to AC mode and the 28.5 V rises from 27 V to
28.5 V. During this sequence the DC out alarm is suppressed.
• Fan supply output voltage is also controlled by the CAN Bus in 5 steps from 24 V to
12 V. The highest value is set by CAN Bus or automatically.
• DC operation only: Prevents AC fail alarms (and associated LED) from the PSU on
CAN Bus when the PSU is supplied from DC only. If the AC supply becomes present
during DC operation, the AC Source Fail alarm circuit is automatically be reactivated.
• AC operation only: Prevents DC fail alarms (and associated LED) from the PSU on
CAN Bus when the PSU is supplied from AC only. If the DC supply becomes present
during AC operation, the DC-Fail alarm circuit is automatically reactivated.
• No Fan 1: Prevents Fan 1 alarm (and associated LED) when no fan 1 is connected. If
the Fan1 becomes present during operation, the Fan1 alarm circuit is automatically re-
activated.
• No Fan 2: Prevents Fan 2 alarm (and associated LED) when no fan 2 is connected. If
the Fan2 becomes present during operation, the Fan2 alarm circuit is automatically re-
activated.
• No Fan 3: Prevents Fan 3 alarm (and associated LED) when no fan 3 is connected. If
the Fan3 becomes present during operation, the Fan3 alarm circuit is automatically re-
activated.
Note: See the MMI Commands manual for additional information on com-
mands and parameters.
Monitoring:
• Cavity status.
• ATCC Heartbeat signal: heart beat signal is repeated every 30 s.
Alarms:
• Software corrupted.
• Distance between two channels below 150 kHz.
• Cavity VSWR alarm.
• Master Slave communication error.
• Motor alarm.
• Cavity tuning error alarms together.
• VSWR exceeded the specified value.
• Unable to park cavity.
• Cavity unable to tune to the current frequency in 3 attempts.
