ALIBRATION
The CAL switch performs a ‘calibration’ of system currents. The purpose of this is to allow the
user to set up a ‘window’ in which, the various currents can be monitored and if the current goes
outside of the ‘window,’ an alarm will be activated. This switch ‘calibrates’ all currents of active
devices. When pressed, the associated LED flashes momentarily to indicate the ‘CAL’ process is
occurring (refer to Table 7-1 for various LED conditions).

ODE
The Redundancy Mode switch enables/disables AUTO mode, this is indicated by the associated
LED (refer to Table 7-1 for various LED conditions). When AUTO mode is enabled, the LCS-4
will automatically switch between BUC and LNB in Redundancy Mode when a fault occurs. The
keypad and Remote Port are also ‘locked’ out when in AUTO mode to prevent any accidental
configuration changes. When disabled, the LCS-4 will not switch automatically. This mode also
is used to do manual changes in the configuration using the front panel and Remote Port.
