Specifications
9-6 Efficia CM Series Rack and Modules Instructions for Use
Rack Power
When running on batteries, the connection of previously disconnected modules is not
always possible. When the rack detects that module will not be able to be powered
without affecting the monitor, the slot is turned off. The module will be displayed as
malfunction.
Parameter Specification
Rack Power
If the monitor is powered by at least one 9-cell battery (1
x9 cell or 2 x9 cell or 1 x 3cell and 1x9 cell) and not
plugged into AC Power, the rack works normally while the
charge of the highest charged 9-cell battery is above
50%.
For the monitor running on battery power (without AC):
• Disable rack operation if only a 3-cell battery (single
or dual) is installed.
• Enable rack operation while a 9-cell battery is
installed.
• Enable Gas module operation as long as the battery
capacity is over 3900mAh.
For a monitor running on battery power, with a battery
capacity lower than:
• 800mAh for 12" monitor
• 900mAh for 15" monitor
When the monitor is connected to the rack (with or
without modules), a battery extreme low alarm will result.
The modules and rack are not being powered on due to
insufficient power availability.
Rack power with Gas
module
If the battery goes below 50% while a Gas module is
connected, the module is disconnected and the rack
keeps working normally. An alarm is triggered to inform
the user: GAS Unavailable - Low Battery.
If the user tries to connect the Gas module while the
battery is below 50%, and not connected to AC power, it
will be rejected. An alarm is triggered to inform the user:
GAS Unavailable - Low Battery.
If a user connects a Gas module to an AC powered
monitor while the battery is below 50%, the rack and Gas
modules will work normally.
For information about enabling rack operation with a 9-
cell battery, using the Gas module, see “For the monitor
running on battery power (without AC):” referenced
above.
