Base Transmitter (Magnetron) 2-11 ENTERPRISE ELECTRONICS CORPORATION
ALARM CURRENT MONITOR
Pictured above is the Alarm current sensor and alarm circuit board mounted on the Mag-
netron Blower Assembly. This module monitors the Magnetron blower for proper opera-
tion via current flow. If the current drops below a pre-set limit due to either motor failure or
other faults, the alarm circuit initiates a controlled shutdown of the transmitter thus pre-
venting damage of critical components. There are no adjustments or other periodic main-
tenance required.
