If you are only using one port, the setting of other power ranges does not matter, but set the

"continuous transmit" to disable. This will prevent the alarm from triggering at "zero" power.

If AC power to the unit fails, the Model 81096 will maintain the proper settings in the

nonvolatile memory.

Alarm Setup

Model 81096 is equipped with an audible alarm. When a fault is detected and the system is

tripped, the alarm will sound. Terminals 4, 5 and 6 will switch if either system one or two

faults and can be used for an external alarm. These contacts are normally open and close

during a fault condition. These contacts have a rating of 2 Amps at 115 VAC. The alarms

are set using an Ethernet crossover cable.

If you do not want the alarm operational for low forward or reflected power, set the low limit

to zero. If you do not want the alarm to function on high forward or reflected power, set the

alarm to the power rating of the element.

Set the high limit on the reflected channel to above what you expect to have reflected back

from your transmitter antenna. The arrows on the elements indicate the power flow direction

sensed by each element.

Control Contacts

Three sets of control contacts are provided. They are labeled on the rear panel. Terminals 1

and 3 provide a remote reset function, terminal 2 is a 5 V supply rated at 0.5A. Terminals 4,

5 and 6 will switch if either system faults and could be used for an external alarm. Terminals

7, 8 and 9 are for the transmitter monitored by port 1; terminals 10, 11 and 12 are for the

transmitter monitored by port 2. This allows protection for combined transmitter systems or

shutdown of drive and final amplifier simultaneously.
