Remote Operation
4-4 TM-F1OP-C1XN-01
To set up remote analog programming:
1. Turn the power supply OFF.
2. Set switches SW1-1, SW1-2, SW1-3, and SW1-4 according to the
programming sources that you are using, as indicated in Table 4-2 .
See Notes at the end of this procedure for more information about
switch settings.
3. Install any required J2 connector jumpers as indicated in Table 4-2 .
4. Connect the programming source(s) to the mating J2 connector as
shown in Figure 4-1 and observe the correct polarity for voltage
sources. Ensure that the mating connector is plugged securely into the
rear panel connector.
5. Set the programming sources to the desired levels and turn the power
supply ON. The REM LED turns on. Adjust the external
programming source to change the power supply’s output.
Please remember:
• Any of the eight switches on SW1 is OFF (OPEN) when it has been
flipped up to break contact, ON (CLOSED) when flipped down to
close contact.
• Resetting switches SW1-3 or SW1-4, the programming scale
selection switches, may require that you recalibrate the programming
circuit to maintain programming accuracy. See
“Calibration and
Troubleshooting” .
• Switches SW1-5, SW1-6, SW1-7, and SW1-8 are not required for
remote programming. They remain at the settings you have selected
for your application.
• Switches SW-1 to SW-4 can be set to their defaults (1 and 2 open, 3
and 4 closed) unless otherwise specified in
Table 4-2 . See “Rear
Panel SW1 Switch” on page 1–7 for default settings.
• The control circuits have been designed to allow you to set output
voltage and current up to 5% over the model-rated maximum values.
The power supply will operate within these extended ranges, but we
cannot guarantee full performance to specification.
