3) Make sure that the RF output interlock is properly calibrated as described
3. Is the FAULT LED lit?
◦ If no, go to the next step.
◦ If yes, the unit has detected a fault. This fault will generate an error code
which can be read on the front panel numeric display and is also provided
through the serial port.
4. Is the RF ON LED lit ?
◦ If yes, go to the next step.
◦ If no, the unit may not have received an RF on command.
1) Make sure you are in the correct communications mode (user or host).
2) If unit is controlled through the RS-232 Host interface, make sure there
3) Verify that set point in power control mode is set between the minimum
5. Is the POWER LIMIT LED lit?

◦ If yes, see
6. Turn the unit off. Verify that the unit has been installed correctly and then
follow the procedure for first time operation. If the problem persists, contact
AE Global Services.

To Troubleshoot an Overtemperature Condition

If your unit has an overtemperature condition with the OVERTEMP LED lit, it
means that either the cold plate temperature or the internal air temperature has
exceeded the limit, disabling output. Usually, disabling RF output stops temperature
rise and the unit starts to cool down.
However, if external air temperature or the temperature of the cooling water is
extremely high (above overtemperature limits), the internal temperature will continue
to rise, and when it reaches 65°C (149°F), it will disable the auxiliary power supply.
In this case, the display and the internal fan will stop working and the unit will not
communicate through the interface ports.
The overtemperature fault clears when the internal temperature falls below fault
levels.

is positive voltage between 4 V and 24 V supplied to pins 4 (positive)
and 17 (return) of the User port. If this voltage is interrupted even for a
short time, the unit will turn output off. To reset the unit, restore the
voltage and through the serial port send an RF off command and then
send an RF on command.
and maximum specifications. In voltage control mode, verify that set
point is set at 20 V or more.
