Programming
Front panel programming and the diagnostic mode are accessed by key press combinations entered within
3 seconds of power up. During this period, all of the LEDs illuminate as an indication that programming
changes can be made.
Access to the programming and diagnostic functions can be disabled by SWA-8. This allows the
installing technician to set parameters and then disable access to programming functions. When
disabled, users cannot accidentally change parameters.
F1 through F4 function tones are set at the factory to the following frequencies:
F1 = 1950 Hz
F2 = 1850 Hz
F3 = 1750 Hz
F4 = 1650 Hz
To adjust and program the tone durations and frequencies, see the Programming Mode Chart on page 20.
Frequency adjustments are made in 100 Hz increments. The tables below show the conditions of the
LEDs in the respective
