ELECTRICAL SYSTEM
WARNING
WARNING – When servicing the
table, turn power off or remove the
appropriate fuses to prevent personal
injury. If power is required, use care
to avoid contact with live parts.
NOTE
NOTE – The table can be factory
configured for 230 VAC operation
based on customer order requirements.
The modifications involve only
components associated with the AC
mains supply. The information below
describes only the 115 VAC
components. Refer to the schematic
diagrams in Section 5 and the parts
listing in Section 8 for identification of
the 230 VAC components.
The OPERON B 810 electrical system schematics
(wiring diagrams) are provided in 2 sections.
FIGURE 5-2 (including 4 detail sheets) shows the
system electronics. 0 is a schematic of the base
electrical wiring.
The electrical system is made up of 8 parts:
1. CPU and Auxiliary Board
2. Connector Board
3. Extension Board
4. Position Sensors and Switches
5. Power Supply System
6. Power Input System
7. Controls (Main and Auxiliary Pendants)
8. Slide Motor.
CPU and Auxiliary Board
The Central Processing Unit (CPU) consists of a
main and an auxiliary board. The CPU is the brains
of the table. It contains the software and controls the
operation of the solenoids and power unit based on
inputs from the operator (via the pendant) and signals
from the table (via the positioning sensors and
switches).
A second CPU serves as a back up for the primary
CPU. In the event of a failure of the primary CPU,
the primary hand pendant connection can be moved
from connector CPU J6 (the factory setting) to CPU
J4. The table will operate with all of the same
functions and capabilities whichever CPU is
providing the control and monitor functions.
The Auxiliary board is mounted piggy-back on the
CPU board. Its primary function is to route input and
output signals between the CPU and the table’s
sensors and actuators.
The CPU and Auxiliary boards are located on the left
side of the column (FIGURE 4-21).
FIGURE 4-22 shows the connections and identifies
the cable routings from the CPU (CPU). FIGURE 4-
23 shows the connections and identifies the cable
routings from the auxiliary board.
TABLE 4-4 identifies the power connections on the
CPU’s J2 and J4 connectors. TABLE 4-5 provides a
listing of all the cables and describes their
connections.
Neither the CPU nor the auxiliary board contains
field serviceable parts. Either must be replaced as a
complete assembly.
