Remote Emergency Power Off (EPO)
Also included in the Disconnect menu is the ability to Enable/Disable the remote Emergency
Power Off (EPO) feature. If enabled, the controller will interpret a contact closure on the
alarm terminal block interface to open the battery contactor. The battery contactor will open
five seconds after the contact has been asserted. Once the contact is removed, the battery
contactor will be re-asserted to its previous operational state.
Ringers
The QS841A can manage up to eight ringer chassis. Ringer operation parameters that include
the ringer output voltage (65-100VAC), ringer output frequency (15-50Hz), whether it has
remote DC Offset (Enabled/Disabled), and if the ringer chassis is operating in the redundant
mode (Enabled/Disabled) are defined in this configuration menu.
Boost
The Boost function allows battery charging to be expedited by raising the system voltage to
Boost level for a set time. The following boost mode parameters are set in this area of the
menu system:
Set Point Boost voltage (set point) is adjustable from -48.0V to -58.0V in 0.1V
increments. The factory default setting is -55.2V.
Voltage Alarms High voltage alarm thresholds in effect while the system is in boost
mode.
The Very High Major alarm triggers shutdown of the faulty
rectifier(s). This threshold can be set from -50V to -60V. The factory
default setting is -57.0V.
The High Minor alarm does not force rectifiers to shut down. The
threshold can be set from -50 to -60V. The factory default setting is -
56V.
The Battery On Discharge alarm is low voltage alarm setting while
in Boost that operates similar to that on Float. The threshold can be
set from -46 to -55V. The factory default setting is -51V.
Max Duration Duration the system can remain in boost mode can be set from 1 to
80 hours. The factory default setting is 1 hour.
Automatic Enabled or Disabled the automatic boost feature. The factory default
setting is Disabled.
