
8.2 Sense Mode - Normal and Generator Waveforms
This is used to broaden the input parameters to accommodate the voltage fluctuations
created by a backup generator or a noisy line.
The factory default setting is normal, where the unit runs on normal parameters. Switching to
Generator makes it run on noisy generator parameters.
If the unit constantly switches between line and battery modes due to a noisy line, select
generator mode to prevent unnecessary transfers / returns.
In generator mode, the acceptable range of input frequency and voltage is expanded to
accommodate the voltage and frequency fluctuations created by a generator or a power
source of such kind.
Use a generator with electronic speed and voltage controls which typically produces Total
Harmonic Distortion in % (THD) of less than 10%. Generators with mechanical governors
can force the system to run continuously in Battery mode.
Before installation, compare the generator’s output voltage to the TRTC-2002-N1’s input
voltage requirements as listed on both nameplates. To insure the system’s smooth operation,
use a generator capable of supplying 2X or twice as much power as required by the total
load.
