Message Description
OFF The power is turned on to the power supply. The lamphead is in the Off mode.
WARMUP The magnetron filament is energized. This message will only be present for
the filament warm-up time period, which is about 15 seconds.
STDBY The filament is warm and the unit is waiting for an On command.
LMPDLY
Lamp Delay
Lamp ON has been enabled. The power contactor is closed, and high voltage
has been applied to the magnetrons. This message is present only for the
lamphead warm-up period, which is about 10 seconds.
LAMPON Lamp is On at the set power level.
L COOL
Lamp Cool Down
Lamp was On and a Standby command has been received. The magnetron
power is shut off and the contactor is open. This message is present only for
the cool down period, which is about 20 seconds. The lamphead then goes to
a standby state. The unit will not restart until the delay time expires.
C DLY
Cool Down Delay
An Off command was received. The lamphead power is turned off. The
message is present only for the cool down period, which is about 60 seconds.
The unit will not restart until delay time expires.
IDLE Lamp is in a very low power state 5% of full power.
Fault Messages
When a fault is detected, the power supply shuts down the high voltage,
turns on the FAULT relay output, and displays a fault message. Table 4-3
lists the fault messages.
Table 4-3 Fault Messages
No. Fault Message Description
0 NETWORK CONFIG Duplicate system IDs on network.
2 FILAMENT FUSE BLOWN There is no current detected on the filament transformer circuit
when the power supply is turned on.
3 HIGH CURRENT ON MAG High current has been detected on high-voltage circuit. The
magnetron exceeds 950 Ma.
4 CURRENT IMBALANCE The magnetrons are turned on (LAMPON) and the magnetron
currents differ by more than 100 ma for a period exceeding
about 600 ms.
5 ON NETWORK UNIT There is a fault on a remote/slave unit.
6 MAG POWER WHEN OFF Magnetron current sensed in standby mode.
7 NO LIGHT DETECTED There was insufficient output from the light detector when the
power supply energized the magnetrons in the Lamp On
mode.
9 HARDWARE FAILURE The power supply is not communicating with the light board.
