Sri 8610C GC User manual

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Remove the six Phillips head
screws holding the bottom of the
GC.
Tilt the GC on its back and remove
the bottom cover. Disconnect the
ground wire so the bottom cover
can be moved out of the way.
Important:
Disconnect the AC
power cord

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Mount the solid state relay module
on the aluminum plate next to the
fan.
Mark the hole locations and then
drill two 5/32” holes.
Use two of the screws and lock-
nuts to secure the solid state relay
module.

SRI 8610C GC
Crimp the black wire to a ring ter-
minal and then screw it to Termi-
nal#1 on the Solid state Relay.
Cut the fuseholder wire about 3
inches from the fuse.
Crimp the longer side of the fuse-
holder wire to a ring terminal and
then fasten to Terminal#2

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Crimp the yellow and green/yellow
wires in the ring terminals. Con-
nect the yellow to terminal#3 and
the green/yellow to terminal#4.
Snap the plastic cover over the
solid state relay module.
Replace the aluminum plate letting
the four wires dangle for the time
being.
Use a hammer and screwdriver to
remove the knock out plate for the
power jack located on the rear of
the GC’s right side.
Use a file to smooth the
edges of the hole
so the jack slides in easily.

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Run the fuseholder wire, the white
wire and .5meter long length of the
green/yellow wire out through the
hole in the chassis. Slide a sec-
tion of heat shrink tubing onto
each wire before soldering to the
power jack.
The fuseholder wire is connected
to the terminal marked ‘L” ( line )
The white wire is connected to the
terminal marked “N” ( neutral )
The green/yellow wire is soldered
to the middle terminal which is
marked with the ground symbol
Secure the jack in place with two
screws and locknuts. Use a stick-
pad and tiewrap to secure the
fuseholder near the jack.

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Crimp the two green/yellow wires
( from solid state relay and from
power jack ) to a single ring termi-
nal and then connect the ring ter-
minal to the chassis ground stud
with a lockwasher.
Connect the yellow wire from the
solid state relay to theA/D board
terminal labeled “D”. TheA/D
board has eight digital outputs ( A-
H ). The yellow wire can be con-
nected to any of the digital outputs
if desired, but we normally use “D”
unless it is already occupied with
some other function.
Route the wires neatly through the
GC. Often there will already be a
wire bundle and clamp through
which you can run the wires.

Installation of the Vacuum Pump Interface on the
SRI 8610C GC
Connect the white and black wires
(white from power jack ), ( black
from soild state relay ) to the third
and fourth terminals from the left
on the display board. There will
already be a white and black wire
inserted into these terminals.
On the model 310C GC connect to
the two rightmost terminals in-
stead.

Label the Relay Function table on
the right side of the GC with the
Relay letter ( A-H ) to which you
assigned the Vacuum Pump Inter-
face .
Then test the
actual vacuum
pump by turn-
ing Relay D ( if
that’s the one
you assigned )
on and off us-
ing the View/
Relay Window
screen in
PeakSimple
A simple schematic of the vacuum
pump interface wiring is shown
