TO INSTALL AN ADDITIONAL MODULE:
Select which of the three positions that will be occupied by the new circuit
board module. Remove the mainframe from the rack and disconnect the power.
Remove the bottom cover, and the #4-40 x ¼” mounting studs adjacent to the new
modules location from the mainframe. Remove the appropriate rear panel connector
cover (blank) from the mainframe. Then remove the appropriate front panel
“nameplate” blank from the mainframe.
Install the new circuit board module with the components toward the top cover.
Take care to avoid moving any of the pre-set controls (just a slight change can cause
the unit to malfunction). Slip the connectors through the holes in the rear panel and
drop the front edge of the circuit board onto the brackets attached to the front panel.
Install the two 3/8” lock washers and the two 3/8-32 nuts on the outermost “F”
connector barrels. Gently tighten the nuts while holding the circuit board against the
front mounting brackets. Next install two #4-40 x ¼” studs and the lock washers to
secure the front of the board to the mounting brackets.
Remove the top over from the mainframe. Connect the negative DC supply to
the new circuit board from the PMS610 power distribution wire. 0.025” square
connector pins are used, usually connected to a multiple jumper daisy chain
(provided) with mating female connectors which connect from one circuit board to
the next. Power supply return is through the chassis.
Push any L.E.D.'s (Light Emitting Diodes) straight into the appropriate
mounting holes. (See instructions for the particular module being installed). Insert
only until the dark collar around the colored LED is flush with the front panel, the
collar must not protrude, in order to avoid interfering with the new nameplate.
Mount the new front panel nameplate (Furnished with the circuit board module
being installed). Temporarily set the new nameplate in place and check that all
necessary cutouts are clear. Remove the paper peel coat from the adhesive backing
of the nameplate, then slide the nameplate down around the L.E.D.'s onto the panel.
Press gently to set the adhesive.
Mount any additional panel components (switches, meters, potentiometer, etc.)
with the hardware supplied. Gently tighten the fastener to secure the components,
do not over tighten the hardware.
Mount the new rear panel connector identification strips as illustrated in the
instruction book for the particular module being installed. Connect input, output, and
power cables. The green “POWER ON” indicator should be illuminated. Set any
internal controls as required.
