LED INDICATOR
The front panel tri-colour LED indicates the operating state.
YELLOW
The middle LED will illuminate YELLOW when 24Vdc supply is applied.
Normal condition is ON
GREEN
The top LED will illuminate GREEN when Amplifier and AO thermal interlocks*
are valid.
Normal condition is ON
RED
The lower LED will illuminate RED when the following signals are all true:
1) RF DC power is applied and
2) Amplifier and AO thermal interlocks are valid and
3) Gate signal is valid (via J9 of the iMS4 plus Software command)
Normal condition is all ON
* Thermal Interlocks
The AOM and Driver are fitted with thermostatic switches which will switch open circuit if a
predetermined temperature is exceeded. These thermal interlocks will reset once
the AO device and /
or RF driver are cooled below this temperature.
- The driver thermal switch over-temperature threshold is 50deg C
- The AOD thermal switch over-temperature threshold is 36deg C
The hysteresis of the thermal switches is 7-10deg C.
Once in a fault state the coolant temperature will need to be reduced to reset the thermal
switches.
