Operation
This section of the manual assumes that the IQH3B Enclosure has been installed in
accordance with the instructions given in the Installation Manual. It describes the operation of
the unit by means of the RollCall Control Panel software.
To fully conform with EMC and Safety standards, modules must be correctly installed in the
mainframe. Prior to connection of power the user should check the following items:
•
The rear of the mainframe must have a full complement of rear panels. Any vacant
slots must have a blank rear panel fitted.
•
All mainframe covers and rear panels must be fitted and screwed down using all
available fixing holes.
•
The mainframe front panel must be in the closed position, with the turnbuckles and
screws fastened.
4.1 Unit Status
This area of the template displays abbreviated information about the current status of the unit.
4.1.1 Line 1
This will normally show the output voltage of the power supplies for example:
PSU: +7.6V -7.8V
If a PSU error is detected or a voltage measurement is out of range then the text will toggle to
one of the items in the list below:
4.1.2 Line 2
This will show the Inlet and Outlet temperatures (in Celsius) of the enclosure.
Normally this would show for example:
TEMP: 28C 27C
Where the first value is the inlet temperature and the second value is the outlet temperature.
This display does not toggle. If any errors occur these are specific to the outlet sensor only.
