ALARM CODES TABLE
Alarm Code Description Cause/Solution
AIR 06
Low Air
Pressure
from head
If it isn’t used the related input must be grounded.
If used, contact grounded=OK, open=alarm
Check head air filter.
H20 07
Low Water Flow
from head
If it isn’t used the related input must be grounded.
If used, contact grounded=OK, open=alarm
Check head water flow.
LOCK 08 Open Interlock
Check interlocks on magnetron head assembly including
waveguide. Check 25 pin D-Sub interlock
LEAK 09 Current Leakage
Check Connector # 3 for signs of arcing: in case replace both
socket & plug with new one.
Check arcing on the magnetron head.
in case replace the magnetron
RACK 10 Rack Error
The unit has detected an output current 10% lower than
expected, usually due by a sudden drop of the main line voltage:
check the main line
MREV 11
Maximum
Reverse Power
Exceded
The reverse power threshold has been exceeded. Check the
threshold limit setting.
POWD 12 Power Down
a) The alarm “Power Down” is enabled and the line voltage has
been suddenly removed while the unit was in MW-ON. Check
main line for faults
b) Disable “Power Down” alarm: the only disadvantage is the
unit will not inform you of unexpected main voltage removal
when in MW-ON state
RAM 13 Ram Error
Internal RAM memory data corrupted: check for Ram Battery
presence (it’s a “click on” battery installed over the CPU Ram) or
charge. Replace the battery. Switch OFF the unit and restart.
COM 14
Communication
interrupted
The unit was running in “remote control mode” and the
communication failed. Check:
a) cable and connectors insertion
b) remove any “suspend or low power mode” from yr PC (the OS
may stops to drive the PC serial port)
c) disable any screen saver from the PC
d) do not move the FrontPanel window on yr desktop: some
early version of operating system may stop driving the serial
port.
e) Raise communication timeout setting in FrontPanel.
