14. Close and secure the SP service door.
15. If you removed the SP from the AE rear panel:
a.
Lift up the SP, align the four hooks on the rear of the SP with the
mounting rails on the AE rear panel, and hang the SP onto the rails.
b. Replace any modules that were removed from the lower shelf of the AE.
c.
Replace the two access panels on the exterior of the AE.
16. Reconnect the liquid lines and fitting plugs that were removed from the old
valve.
17. Plug in the power cord and turn on the power.
10.9 Changing the Peristaltic Loading Pump Speed
When a peristaltic pump is installed in the SP, one of the solenoid valve
connectors (typically
SV9
) on the main SP electronics board is assigned to control
the peristaltic pump rather than a solenoid valve.
A cable from the peristaltic pump plugs into the main SP electronics board
.
Turning the associated potentiometer changes the voltage to the pump and thus,
the pump speed and flow rate.
To change the peristaltic pump speed:
1. Turn off the SP power.
2. Disconnect the power cord.
3. Follow the instructions in
to access the main SP electronics
board.
4. Locate the two potentiometers on the left side of the main SP electronics
). The potentiometer farthest to the left (at position
R108
on the board) controls the speed of the peristaltic loading pump installed
in an SP2.
5. Adjust the pump speed as follows:
•
To increase the pump speed, turn the potentiometer counterclockwise.
•
To decrease the pump speed, turn the potentiometer clockwise.
