CHP Max DC Power Supply

The factory-default threshold and deadband values for each parameter are listed in
Table 5.4. A deadband or hysteresis value prevents alarm oscillation. Once a threshold is
exceeded, the alarm can only be downgraded if the parameter is at least a deadband below
the threshold value.
➤
To adjust the alarm threshold limits
1. Follow the procedures for
Local Monitoring with the CHP-CMS Craft Management
2. Double-click the PS module identifier in the module inventory or double-click on the
desired power supply module in the image map to open that module’s management
window.
3. Right click on the Internal Temperature meter and select
Configure
from the shortcut
menu. Refer to Figure 5.9.
4. In the Alarm Setup area, drag the slider or enter the desired alarm limit value for the
Major low, Minor low, Minor high, and Major high. Click
OK
to save these alarm limit
values.
5. Right click on the +12 VDC meter and select
Configure
from the shortcut menu. Refer
to Figure 5.9 on page 5-12.
6. In the Alarm Setup area, drag the slider or enter the desired alarm limit value for the
Major low, Minor low, Minor high, and Major high. Click
OK
to save these alarm limit
values.
7. Repeat Steps 5 and 6 to the +5 VDC, +3.3 VDC, and –5 VDC meters if you want to
adjust these alarm threshold values.
