4.6 REMOTE MONITORING OF READBACK

SIGNALS AND STATUS INDICATORS

4.6.1 Readback

Signals

Calibrated readback signals for remote monitoring of the output voltage and current are
available via connections at the J3 connector on the rear panel. Internal switch SW1 settings
allow you to select either a 0-5 Vdc or a 0-10 Vdc range for the output. See Section 4.2
Configuring for Remote Programming, Sensing, and Monitoring
for more information about
making these connections.

The following table shows the required pin connections and switch settings for remote
monitoring of readback signals with 0-5 Vdc or 0-10 Vdc outputs. Use shielded-twisted pair
wiring (20 to 24 AWG) and ground the shield to J3 connector pin 6 or to the chassis via one of
the J3 connector screws.

The readback signal represents 0 to 100% of the model-rated output.

4.6.2 Status

Indicators

Status indicators for thermal shutdown, OVP circuit, programming mode, and operating mode
are available via connections on the J3 connector on the rear panel.

The following table shows the indicator signals, the J3 connector pin at which they are available,
an approximation of the signal magnitude, and the source impedance through which the signal
is fed. Use 20 to 24 AWG wiring.
