Power Lockout
The
Power Lockout
page (see Figure 2.74 ) allows you to set a high power limit for the
transmitter. There is provision to set up to eight different limits (which can be used to
accommodate daytime/night-time patterns or different antennae), but only the selected limit is
active. You can also select a high power limit using a digital remote input (see Remote inputs
on page 2-124 ).
The transmitter power cannot increase beyond the active limit. For analog and hybrid modes
of operation the displayed power limits represent carrier power. For DRM mode, the
displayed power limits represent RMS power. If the active preset set point is greater than the
active lockout limit, a
High Power Lockout
alarm will appear on the
Transmitter Status
page.
For basic transmitter operation, you must configure and enable at least one of the eight high
power limits.
Max Power Lockout 1
is factory set for the transmitter’s maximum output power.
Set up a power lockout as follows:
