To Clear an Alarm
Depending on the cause of the alarm, the alarm may be cleared
automatically as soon as the fault condition has elapsed. In some cases,
the alarm is cleared by:
• cycling the ON/OFF switch on the rear panel,
• toggling the Shut_Down user line,
• or toggling between Standby and Active buttons on the Web Browser
interface (if Ethernet Option is being used).
Maintenance
Periodic
Cleaning
Whenever a unit is removed from operation, clean the outside surfaces
with a weak solution of soap and water. If required, use low-pressure
compressed air to blow dust from in and around components on the
printed circuit boards.
Fan Filter
Replacement
The XDI is fitted with disposable fan filters which prevent the entry of
dust and debris into the unit. These filters should be inspected every six
months. When the filters become dirty they can be replaced as shown in
Figure 3-4.
