Upgrading to Dual Exciter
The NV20LT/NV15LT is factory configured with a single exciter - part of the controller (A4). You can
upgrade your transmitter with a second exciter (exciter B). which provides additional redundancy.
1. Turn off (disable or lock out, as applicable) the main ac power for the transmitter.
2. Obtain “QG12004* - NVLT Dual Exciter Upgrade Quick Guide” (see Figure 2.3.1 ) that was provided
with the Dual Exciter Upgrade Kit and complete its outlined procedure.

3. If you are performing this upgrade in conjunction with the NV20LT/NV15LT’s initial installation,
leave the front and rear panels off to allow further installation. If you are performing this upgrade
after initial installation has already been completed, re-install the front and rear panels.
