Power Input Center
Figure 5-14 Power Input Center
The power input center contains 4 elements:
1. The AC input receptacle
2. The AC fuses (F1 and F2)
3. The charge indicator LED
4. The ground stud
The AC input line and neutral are fused with 8
Amp time delay fuses.
The charge indicator LED illuminates green
when AC is applied to the table and the batteries
are charging. The indicator should always be
illuminated if AC is applied.
CONTROL PENDANTS
Primary Hand Pendant
Commands are entered on the primary hand
pendant through the keypad.
The primary hand pendant sends commands to
the CPU via connection J29 on the CPU board.
An illustration of the primary hand pendant
along with function and LED display
descriptions is provided in the General
Information section of this manual.
If the primary hand pendant is not
communicating with the CPU, the SERVICE
(Service) LED will blink.
Pendant backlighting (electroluminescent panel)
combined with the green Power LED indicates
that the pendant is active. The Backlight will
time out after a preset time
period, which can be
set in the service software. The backlight timer
can be set to a shorter time than the Controls
Wakened state. This will reduce electrical
current drain on the batteries, slightly extending
the battery charge cycle. The lowest backlight
timer setting is 1 second.
Pressing ON while a function is running will
stop the function. Pressing any other function
button while a function is running will stop the
articulation. To start the articulation, release the
function button and press it again.
Pressing POWER while a function is running
will stop the function and turn the table off.
Figure 5-15 Primary Hand Pendant
Pulling out the foot pedal activates the
auxiliary pendant (shown by the flashing
indicator on the primary pendant), and
deactivates the primary hand pendant. Thus, if
a function is pressed on the primary pendant
while the auxiliary pendant is removed,
primary pendant function will not work and the
hydraulic pump will not run.
There are no field serviceable parts in the
primary hand pendant. It must be replaced as a
complete assembly.
