GENERATOR CONFIGURATION
The Generator Configuration program is run first - to verify all settings are cor-
rect, followed by Calibration - to ensure optimal generator performance. To gain
access to either of these utilities, password entry is required. This is to prevent
unintended and/or unauthorized changes to system settings.
Generator Settings Tab
If not already done so, select the Generator Settings tab on the Configura-
tion Menu. The Generator Settings, shown in Figure D-4, includes controls
for setting the generator power output derating (presented as a percentage
of total power output (kW)), sleep mode timer, AEC Board Type, and AEC
Backup mAs settings.
1. DeratingPercentage - The derating function is used to limit the output
of the system to a percentage of the maximum energy capacity. To der-
ate the energy output, move the slide control adjacent to the Derating-
Percentage field to the desired derating percentage (choices are 80%,
85%, 90%, 95% or 100% [i.e., no derating]).
2. Timeout: The "timeout" period selected represents the amount of delay
time after which, if no user activity is detected, the system automatically
enters Power Stand By mode. This mode is entered to help reduce power
consumption while protecting system electronics. The timeout period is
selectable in 30 minute increments between 0 minutes up to 180 min-
utes. If "Infinity" is selected, the generator will not timeout, however, the
filament will turn off if one hour of inactivity.
3. AECBoardType: Displays the AEC Board type installed in the generator
(when equipped with AEC option):
a. Select "Standard" if generator is equipped with standard type AEC
Board A11 (AY40-031S)
b. Select "Universal" if generator is equipped with universal type AEC
Board A11 (AY40-027S)
c. Select "None" if generator is not equipped with optional AEC
4. AECBackUp Mas: Sets the current system-wide backup mAs setting
effective on all AEC exposures. The maximum back up mAs setting is
600; note that on certain model generators, such as the Stored Energy
models, the maximum mAs capability of the generator is less than 600
mAs. Therefore, the backup mAs setting should not exceed the maximum
MAS output of the generator. Refer to Chapter 1, SPECIFICATIONS for a
list of the mAs ratings by model number.
