EL 9000 B 15U/24U Series
3.4
Manual operation
3.4.1
Switching on the device
The cabinets of this series are master-slave systems with one master unit and up to 5 slave units. In order for
the master to find and initialise the slaves the fastest way after powering the cabinet, it should be powered last.
Recommendation: power the units in the cabinet from bottom to top, one by one.
After switching on, the display firsts show the manufacturers logo and device related information, as well as a lan-
guage selection screen (for 3 s) and will then be ready for use. In the setup (see section
)
in the second level menu
General settings
is an option
DC input after power ON
in which the user can
determine the condition of the DC input after power-up. Factory setting here is
OFF
, meaning that the DC input will
remain switched off after power-up.
Restore
means that the last condition of the DC input will be restored, either
on or off. All set values are always saved and restored.
It’s allowed to only switch on a lesser number of slave units or just the master unit if the demand
for power with the current application is lower than what the cabinet can bring. Every unit can
sink a certain power (formula: total power of cabinet ÷ number of units). The master unit will
automatically detect the situation.
During boot phase the analog interface will signal undefined statuses on the output pins, such
as ALARMS 1. Those signals must be ignored until the device has finished booting and is ready
to work.
3.4.2
Switching off the device
On switch-off the last input condition and the most recent set values are saved. Furthermore, a PF alarm (power
failure) will be reported, but can be ignored.
Due to the master-slave configuration of the cabinet it’s recommended to switch off the master first.
Recommendation: switch off the units in the cabinet from top to bottom, one by one.
3.4.3
Configuration via MENU
The MENU serves to configure all operating parameters which
are not constantly required. These can be set by finger touch on
the MENU touch area, but only if the DC input is switched OFF.
See figure to the right.
If the DC input is switched on the settings menu will not be shown,
only status information.
Menu navigation is by finger touch. Values are set using the rotary
knobs. The assignment of the knobs to adjustable values in the
sub menus isn’t extra depicted, but there is an assignment rule:
upper value -> left-hand knob, lower values -> right-hand knob.
Some setting parameters are self-explanatory, others are not. The
latter will be explained on the pages following.
