3.6.2 REMOTE VOLTAGE PROGRAMMING BY VOLTAGE SOURCE
Two inputs are provided for remote voltage-programming of the output
voltage: 5 VDC full-scale and 10 VDC full-scale. The DC voltage source is
connected between Pin J1-9 (VP 5 V) for 5 VDC source, or Pin J1-15
(VP 10V) for 10 VDC source, and the return Pin J1-20 (VP RTN).
The corresponding voltage-programming coefficients for output voltage are
(100% rated output voltage) / 5 VDC, or (100% rated output voltage) /10 VDC,
from the respective inputs with return to Pin J1-20 (VP RTN). This produces
transfer functions for output voltage, as follows:
Vout = Vdc * (100% rated output voltage) / 5 VDC), with Vdc in volts, or
Vout = Vdc * (100% rated output voltage) / 10 VDC), with Vdc in volts.
Note:
The return Pin J1-20 (VP RTN) must be referenced directly to, or
within ±3 V, of the circuit common, Pins J1-6 and J1-24. See Figure 3-16 for
connection requirements.
