IQ plus 355 Analog Output Module Installation
To install or replace the analog output module, ensure
power to the indicator is disconnected, then place the
indicator face-down on an antistatic work mat. Loosen
all in-use cord grips and remove the screws that hold
the backplate to the enclosure body. 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.
NOTE: Ensure jumpers JP1 and JP2 on analog output
board are installed in position 1 (POS1) as shown in
Figure 1.
Mount the analog output module on its standoffs in
the location shown in Figure 1 and plug the module
input into connector J5 on the IQ plus 355 board.
Connect output cable to the analog output module as
shown in Table 1, then reassemble the enclosure as
described on page 2.
