ROUBLESHOOTING
The use of highly reliable components in the RMAS-120 virtually eliminates the
need for frequent maintenance. Unless the RMAS-120 is installed in an
extremely harsh environment, routine checks should be performed annually.
Such checks will ensure proper operation and early detection of problems.
Additional trouble shooting details are found in Technical Note 650-1020-01.
4.1
Routine Maintenance
Routine maintenance requires two technicians, one at the receiver site and one
at the transmitter site. Some procedures require that the technicians must
communicate with each other while performing maintenance.
To perform a routine check of the RMAS-120:
1. Observe the installation area and correct any problems (both sites).
2. Confirm that the units are securely mounted (both sites).
3. Confirm that all installation wiring is in good condition and all wiring
connections are tight (both sites).
4. Measure battery voltage and temperature values and compare them with the
values at the receiver. Contact Peninsula Engineering Solutions if there are
discrepancies.
4.2
Troubleshooting
4.2.1 Standard Transmitter Troubleshooting
If there are problems with the Transmitter:
1. Confirm that the modulation strapping is correct. Check the modulation setting
switches.
2. Using an oscilloscope, verify the presence of data at the J3 pins 25 and 26. If the
data pattern is not present, contact Peninsula Engineering Solutions.
3. Contact the receiver site and verify that all LEDs (including SYNC LOSS) are OFF at
the receiver.
