External Connections
Before attaching external wires to the Control-Panel connectors, it is recommended that the Control-
Panel first be connected to a power source to confirm normal operation. If it is functioning properly,
the display should briefly
indicate “
Scaletron Industries
”
followed by data for either one or two
active channels, depending on system configuration, having random (floating input) measurement
values in the selected units.
Reference section titled
for the proper procedure for removing a PCB and making external
wire connections. With reference to the Backplane Board
’s
layout as depicted in Figure 2, identify the
slot locations for the two supported channels and carefully remove the Analog Input Board (AIB) for
the desired channel. All Scale-Base signals, with the exception of any cable shield wire, will connect to
this board. Refer to the instruction manual of your Scale-Base to determine the correct connection to
the Load-Cell and Leak-Detect Sensor Interface terminal blocks. When all wires are connected, re-
insert the PCB following the procedure previously referenced. Connect all cable shield wires to the
threaded-hole locations provided on the top of the power-supply bracket.
If applicable, carefully remove the Analog Output Board (AOB-mA) for the desired channel. Connect
appropriate wires to the Current Loop Interface terminal block. Next, position the board’s slider
-switch
to select the correct configuration for
the loop’s power source. Observe all warnings as outlined in
Analog Output Board (4-20 mA Output)
. When finished, carefully re-insert the PCB
following the procedure previously referenced.
If applicable, carefully remove the Analog Output Board (AOB-V) for the desired channel. Connect
ap
propriate wires to the Voltage Out Interface terminal block. Next, configure the board’s voltage
output range by either installing or removing jumper-shunts. Observe all warnings as outlined in
section titled
Analog Output Board (0-5V/10V Output)
. When finished, carefully re-insert the PCB
following the procedure previously referenced.
If applicable, carefully remove the Relay Output Board (ROB) for the desired channel. Connect wires
to the appropriate Relay Interface terminal block as outlined in section titled
. When finished, re-insert the PCB following the procedure previously referenced.
The AccuPro-
5000™ supports
the attachment of a user-supplied, external indicator or audible alarm
that would be triggered whenever the system detects an alarm condition as defined in section titled
. This feature allows for the notification of events that require attention from
a remote location away from the Control-Panel. Carefully remove the Main Processor Board and
connect external wires to the External Alarm Interface terminal block as outlined in section titled
. When finished, re-insert the PCB following the procedure previously referenced.
Be sure to disconnect power to the Control-Panel
before making any wiring connections. In
addition, anti-static precautions must be followed
whenever accessing the Control-
Panel’s interior
electronics else permanent damage may result.
