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 light as an indication that
programming changes may 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 can not accidentally change parameters.
F1 through F4 are set at the factory to the following currents:
F1 = 5.5 mA F3 = -5.5 mA
