When the transmitter is first started up, or reset, it scans the entire program memory and
compares a checksum of the values in it to the checksum that was calculated when the device
was originally programmed. If these are different the program memory is assumed to be
corrupted and the processor sends the message: “Bad Checksum” repeatedly until the problem is
corrected.
Every time the transmitter is called upon to transmit an alarm, trouble, or test message it sets up
the RF circuitry with the proper parameters. It then reads back the RF programming and if there
is a discrepancy the processor stops trying to transmit and prints the message: “RF Circuitry
Error” repeatedly until the problem is corrected.
After the transmitter sets up the RF circuitry but before it transmits anything it checks to see if
any RF energy is being sent to the antenna. If so, this indicates a hardware error that would
cause the transmitter to tie up the frequency when it is not meant to send a message. In this case,
it shuts down power to the RF circuitry and prints the message: “Unintended RF Transmission”
repeatedly until the problem is corrected.
If any of these conditions occurs, replace the transmitter board immediately.
17. Preventive Maintenance
17.1 Annual Maintenance
➢ Physically inspect STAR
➢ Verify tight connections
➢ Check Battery Voltage – No load, 13.0 VDC or greater
➢ Check Charging Voltage – 13.8-14.2 VDC with battery connected (A battery charged for
a minimum of 2 Hrs.)
➢ Check Battery Voltage – With AC turned off and while a message is being transmitted.
➢ Using the programming app, send a Test transmission and verify proper SWR
➢ Very expected RSS at the receiver (MCR2 only)
