The pendant’s battery status LED display and the
disabling of the motor or solenoid activation will not
change while the motor or the solenoids are active.
The CPU will wait one second after the function has
stopped to sense and act on the battery voltage.
The green and yellow ranges of the LED display will
allow the table to function normally for 1 week under
the conditions specified in the table’s Product
Specification.
The green range indicates that the battery’s charge is
between 90 and 100% of capacity.
The yellow range indicates that the battery’s charge
is between 54 and 90% of capacity. When the yellow
LED illuminates, the batteries should be charged. A
battery with a yellow display will operate a table for
1 week under normal conditions.
The steady red range will allow the table to be used
via the main pendant to activate the solenoids, but the
main hydraulic pump will be disabled. The manual
foot pump must be used to provide hydraulic pressure
in this case. Once the state changes to flashing or
steady red, AC power must be detected to change the
LED display. Connecting the table to an AC power
supply will provide the power to operate all table
functions while recharging the batteries.
From the time that the battery status switches into the
flashing red state, and possibly through the steady red
state, the batteries will have enough capacity to run
the table for at least one day under normal usage
conditions as defined in the Operon B 810 product
specification. The latter part of the operation may
need to be completed via the auxiliary pendant and
foot pump if the status moves into the steady red
state.
The low battery charge automatic shutoff feature only
affects the primary hand pendant and only occurs
during the steady red state. The low battery auto-
shutoff feature will not affect the operation of the
auxiliary pendant. If the battery voltage is below
10% for more than 1 second, the auto-shutoff feature
will turn off the primary hand pendant. If the hand
pendant ON button is pressed after a low battery
auto-shutdown and AC power is present, the table
will power up and all functions will operate normally.
AC Detected
If AC power is detected, the LED display only serves
to indicate the battery status as the batteries are
charging. No functions will be disabled due to
battery problems, because the power supply will
provide current to both the batteries for charging, the
table’s electronics, and the hydraulic pump motor.
If battery voltage is not sensed due to a dead battery,
blown battery fuse, or an open sensor line, the steady
red LED will display and the service LED will light.
An error code also will be logged. All table functions
will operate normally while connected to AC via the
power supply.
The transition voltage for each LED is higher when
charging. This will assure that the operator does not
expect the table to be fully charged if charging is
discontinued at the transition point from a lower to a
higher LED level. See TABLE 6-6 for AC detected
function information.
