5. Plug the PWM power output cable (P/N 070180) into the
Mixer/PWM
connector on the main SP electronics board.
6. On the other end of the power output cable, attach two wires to the 3-position
connector plug. Connect to the two positions required for the voltage range:
•
For a range of 0 to 24 V, attach wires to the
24V
and
PWM
connectors.
•
For a range of 0 to 5 V, attach wires to the
5V
and
PWM
connectors.
To attach a wire to the plug: Strip the end of the wire, insert it into the plug,
and use a screwdriver to tighten the locking screw.
7. Route the cable with attached wires to the device to be controlled, and then
connect the free ends of the wires to the appropriate connector pins on the
device.
8. Close and secure the SP service door.
9. 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 on 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.
10. Plug in the power cord and turn on the power.
11. Open the Chromeleon Instrument Configuration Manager and open the SP
Properties dialog box. The Mixer Motor check box is enabled on the
Pumps/Motors page. Enter the default percentage of power (from 0% to
100% of maximum) delivered when the PWM power output is on.
12. Save the configuration.
When attaching wires to the connector plug, be careful not to allow
stray strands of wire to short to an adjoining position on the
connector.
