6. Attach wires to the 2-position connector plug on the other end of the cable.
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 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 7 Instrument Configuration Manager and open the SP
Properties dialog box. The DC Voltage Control check box is enabled on the
Pumps/Motors page. Enter the default voltage level to use when the DC
voltage control is on.
12. Save the configuration.
3.13 PWM Power Output (Option)
A Pulse Width Modulation (PWM) power output is included with the SP. The
PWM power output is typically used to control the dilution vessel mixer (see
Section 3.5.2 ). However, if the dilution vessel mixer is not required, you can use
the PWM power output for another function. Thermo Fisher Scientific offers a
PWM power output cable (P/N 070180) that allows connection from the SP PWM
power output to an external device.
The PWM power output provides a choice of two maximum voltage ranges:
•
0 to 24 volts DC maximum
•
0 to 5 volts DC maximum
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.
