This page generates programming instructions for RAK-2 and RCS series systems that have firmware version 6 in the embedded RFC-1. Users of earlier models, including RAK-1 systems and stand-alone RFC-1 systems, should use the programming pages that are compatible with those models.
Program a Telemetry Alarm
The RFC-1/B can respond to telemetry conditions using alarms. This requires setting both the alarm conditions and an action sequence.
An action sequence is a series of instructions stored in memory to perform a task. It has no information about when the task occurs.
- An action sequence is a stored set of instructions that perform a task
- An action sequence is triggered by an alarm or a date/time trigger
- The system stores stores eight programmable action sequences
Action sequences can operate control relays, print readings, etc. A typical action sequence to turn on a transmitter is activate a relay, pause several seconds, then activate another relay.
The RFC-1 can store eight action sequences. Each sequence can have eight steps. Steps are performed in order and the sequence terminates at the first blank step.
As of firmware version 6, action sequence 1 is not used in the factory settings. All eight programmable action sequences are unused by default.
The alarm consists of the upper and lower limits and a trigger rule. Upper and lower limits set the tolerance for the channel. The trigger rule determines how the system uses the limits to determine when an alarm occurs.
- Alarm limits are determined by the device that is monitored
- When an alarm occurs it triggers an action sequence
- The system stores eight alarms
Some trigger rules ignore the limits and look for the reading to change by a certain percentage. These rules are useful for stations that operate at multiple power levels.
Alarms limits do not use decimal points and they always use four significant digits. See the links section of this page if you need help determining alarm limits for a channel.
Blocking an Alarm
Alarms can be blocked so that they do not operate during specified hours. See the links section of this page for a page that can assist with alarm block programming if you need help blocking an alarm.
Use the selections below to setup an alarm. All items must be completed.
