Monitor Alarm Limit Configuration Screen
The Monitor Alarm Limit Configuration screen is shown in Figure 3-35. This screen is used to configure the
operation of the Monitors. It contains the Shutdown Delay, the Ident Delays, and the Alarm and Pre-Alarm Limits,
as well as the desired Nominal values for all of the monitored parameters. The Azimuth Angle settings are
separated for Monitor 1 and Monitor 2 to allow for two different field monitor positions. All other alarm parameters
have common limits. The Input attenuation settings allow adjustment of the level from the field monitor antenna to
compensate for line los and distance to the antenna. These attenuators are adjusted so that the RF level reading is
nearly 0 dB as read on the monitors.
