i n s t a l l a t i o n o f t h e a n a l o g o u t p u t o p t i o n a n d
replacement of the CPU board are included, along
with assembly drawings and parts lists for the service
technician.
•
Use a wrist strap to ground yourself and protect
components from electrostatic discharge (ESD)
when working inside the indicator enclosure.
•
This unit uses double pole/neutral fusing which
could create an electric shock hazard. Procedures
requiring work inside the indicator must be
performed by qualified service personnel only.
•
The supply cord serves as the power disconnect for
the IQ plus 710. The power outlet supplying the
indicator must be installed near the unit and be
easily accessible.
2.1
Unpacking and Assembly
Immediately after unpacking, visually inspect the IQ
plus 710 to ensure all components are included and
undamaged. The shipping carton should contain the
indicator with attached tilt stand, this manual, and a
parts kit. If any parts were damaged in shipment,
notify Rice Lake Weighing Systems and the shipper
immediately.
The parts kit contains the items listed below:
•
Capacity and identification labels.
•
Two 8-32NC x 7/16 fillister head screws (PN
30623). These screws occupy the holes above
and on either side of the setup screw on the
indicator backplate (see Figure 2-2 on page
7).
•
Ten 8-32NC x 3/8 machine screws (PN
14862) for the indicator backplate (see #29 in
Figure 2-6 on page 12).
•
Twelve bonded sealing washers (PN 45042)
for backplate screws included in the parts kit.
•
Four cord grip reducing glands (PN 15664).
•
Four rubber bumpers (“feet”) for the tilt stand,
PN 42149.
•
6 cable ties, PN 15631.
2.2
Enclosure Disassembly
The indicator enclosure must be opened to connect
cables for load cells, communications, digital inputs,
digital outputs, and analog output.
The IQ plus 710 has no on/off switch.
Before opening the unit, ensure the
power cord is disconnected from the
power outlet.
Ensure power to the indicator is disconnected, then
place the indicator face-down on an antistatic work
mat. Remove the screws that hold the backplate to the
enclosure body, then lift the backplate away from the
enclosure and set it aside.
2.3
Cable Connections
The IQ plus 710 provides five cord grips for cabling
into the indicator: one for the power cord, four to
accommodate load cell, communications, digital I/O,
and analog output cables. Three of the four free cord
grips come with a plug installed to prevent moisture
from entering the enclosure. Depending on your
application, remove the plug from any cord grip that
will be used and install cables as required.
