Turn-On Delay Setting
NOTE
: The turn-on delay setting can also be adjusted using the remote AUI (see Turn-On Behaviour, on
page 3.2.111 ).
From the front panel UI, you can set the transmitter’s turn-on delay. This setting determines the time
delay for the transmitter to recover from an ac power loss. This is typically used in sites with multiple
transmitters on a common generator. By staggering the turn-on delay periods of each transmitter, you
can reduce the overall load on the generator. To view the
Turn On Delay
screen, select
User
Settings -> Turn On Delay
from the
Main Menu
(see Figure 3.2.102 ).
Figure 3.2.102: Turn On Delay Screen
Use the up and down buttons to select a delay between 0 and 120 s (in 1 s increments). The default
setting is 0 s (disabled). Press the accept (checkmark) button to save the change. Press
X
to abort the
change and return to the previous menu.
Ramp-Up Speed Setting
NOTE
: The ramp-up speed setting can also be adjusted using the remote AUI (see Turn-On Behaviour, on
page 3.2.111 ).
From the front panel UI, you can set the transmitter’s ramp-up speed. This setting establishes the time it
takes the transmitter to ramp up from 0 W to full power. At 100%, ramp-up speed is approximately
seven seconds. For a setting of 50%, ramp-up would be approximately 14 seconds. For a setting of
25%, ramp-up would be approximately 28 seconds. In multi-transmitter systems that are on a common
generator or power grid, adjusting the ramp-up speed can be used to reduce the transient load on the
source during an ac power recovery (i.e., after a power failure or changeover to a generator).
To view the
Ramp-up Speed
screen, select
User Settings -> Ramp-up Speed
from the
Main Menu
(see Figure 3.2.103 on page 3.2.120 ).
