510/710 Digital Weight Indicators
Relay Rack Option
PN 45408
Use the following procedure to install the IQ plus
510/710 relay rack option:
1. 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.
Loosen all in-use cord grips then lift the
backplate away from the enclosure and set it
aside.
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when working inside
the indicator enclosure.
2. A s s e m b l e r e l a y s o n t o t h e r e l a y b o a r d
(4-channel) or boards (8-channel).
3. Install standoffs onto the studs on the
indicator backplate. Mount U-brackets on the
standoffs, place protective shield on top of
brackets, and secure with kep nuts (see
Figure 3 on page 2).
4. For IQ plus 710 indicators using output
relays, remove connector J8 from the CPU
b o a r d a n d w i r e t h e r e l a y b o a r d t o t h e
connector as shown in Figure 1.
For IQ plus 510 or 710 input relays, remove
connectors J7 and J8 from the CPU board and
wire as shown in Figure 2.
NOTE:
For indicators using Rev. 1 CPU boards,
digital input and output connections are made to
the interface board. See the
IQ plus 510/710
Interface Board
addendum, PN 46204, for
connector information.
5. Loosen cord grips and route cables for
external equipment into the enclosure as
shown in Figure 3 on page 2. Attach cables to
relay board as shown in Figure 1 or Figure 2.
