IQ plus 350 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.
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.
NOTE:
Ensure jumpers JP1 and JP2 are installed in
position 1 (POS1) as shown in Figure 7.
Mount the analog output module on its standoffs in
the location shown in Figure 7 and plug the module
input into connector J5 on the IQ plus 350 board.
Connect output cable to the analog output module as
shown in Table 3, then reassemble the enclosure as
described on page 6.
