Error Codes
The Mega Power is designed to assist the user in identifying failure modes. When
specific conditions are met an error code will be shown in the large displays.
If any of the following errors are displayed and are not cleared by turning the system off
then on, record the error displayed and call Megadyne Customer Service at

Error
Code
Description Explanation
201 Communication
Error
Internal communications between internal micro controllers has failed.
202 Watchdog Error Internal Watchdog microcontroller has detected an error and has shut the
system down for safety reasons.
203 Dosage Error The Master microcontroller has detected an excessive amount of power
consumption compared with the RF output power being delivered.
204 Relay Error One or more relays have failed the relay diagnostic test.
205 Activation Error One or more of the foot switches or hand switches were in the active state
during power up.
206 CQM Error An error was detected in the CQM Network during the Power On Self Test
(POST).
207 Front Panel Button
Press Error
A button press was detected during POST, this condition is not permitted.
208 Active Measurement
Diagnostics Error B+
An error was detected in the B+ Voltage sense network during Power On
Self Test (POST).
209 PFC Shutdown The internal power supply has reached an overload condition and has
shutdown. The unit may be reset by turning off the power if the overload
condition has cleared, such as an over temperature condition.
210 Calibration
Constants
Checksum Error
The Master Microcontroller reads the calibration constants and the
checksum from EEPROM. If the values do not match an error is displayed.
211 WD CQM Error The Watchdog has detected a CQM Error.
212 CQM Test Error The WD has detected an error in the CQM Network during the Power On
Self Test (POST).
213 WD Dosage Error The Watchdog Microcontroller has detected an excessive amount of power
consumption compared with the RF output power being delivered.
