Task Manager Inputs and Actions 205
PMU shutdown imminent
This input becomes true when the PMU’s ‘Shutdown imminent’ alarm is
triggered. For information about this alarm, see
“Shutdown imminent” on
page 153 .
PMU temperature high
This input becomes true when the PMU’s ‘Temperature high’ alarm is
triggered. For information about this alarm, see
“Temperature high” on
page 153 .
Reciter alarm on
This input becomes true when any reciter alarm is triggered.
Reverse power high
This input becomes true when the ‘Reverse power high’ alarm is triggered. For
information about this alarm, see
“Reverse power high” on page 150 .
Note:
Use the VSWR fault input instead of the Reverse power high
input if the transmit power is set to less than 20 W or if the base
station has a 5 W PA. The resolution of the reverse power
measurement is 1 W; only a very serious antenna fault would trigger the reverse
power high alarm if the power setting is low.
Synthesiser failed
This input becomes true when a synthesiser goes out of lock or the external
frequency reference is invalid and the corresponding alarm is triggered. For
information about these alarms, see
“Synthesiser out of lock” on page 149 and
“External reference invalid” on page 152 .
VSWR fault
This input becomes true when the ‘VSWR high’ alarm is triggered. For
information about this alarm, see
“VSWR high” on page 150 .
Custom Inputs
The Custom Inputs submenu contains all the custom inputs that have been
defined for the base station using Configure > Task Manager > Custom Inputs.
Actions
An action is something that Task Manager instructs the base station to do.
There is often a group of actions relating to a particular base station function.
For example, Task Manager can enable, disable, or toggle the talk through
repeater function. Enable makes the function effective, disable makes it
ineffective, and toggle changes from the one state to the other.
Tip:
To obtain Help on a task’s action, click the task. In the
Task
list item area, click the Help icon beside the action box.
General Actions
General actions relate to the general operation of the base station.
