Voltage Maximum VA
1
Typical standby power is 4 VA at 12 VDC for calculating solar power autonomy
2
The optional 40 A relay will add 10 VA when energized
Theory of Operation
The system is activated upon receiving a series of pulses of radio frequency energy within a five-second period.
There are two independent sets of relays that can be programmed for individual or incremental operation. In incremental
operation at the third pulse, the first relay closes, at the fifth pulse, the second relay closes, at the seventh pulse, the third
relay closes. In individual operation only the relay for the selected step is closed at any time.
At any time in the sequence, the pilot has the option of sending three, five, or seven pulses to command the system to the
desired intensity level. The system will remain at the intensity level of the last command received. The solid-state timer will
continue to operate for 15-60 minutes (selectable) after which it will cause the system to revert to the original “off” condition.
The timer is reset by the receipt of any command at any time, unless re-command is set to disable, which requires the L-854
controller to time out before a new command is accepted.
In the event of a power interruption while the relays are energized, the controller and associated relays will resume operation
for the remainder of the period at the previously selected brightness setting.
An ideal application for series constant-current lighting systems is that of operating at a low power setting, using the L-854
controller to bring the lighting to full brilliancy, and if desired, simultaneously energizing the REILs. Maximum life and utility
are thus achieved for both systems. Runway lighting and REIL/xenon flash lamp life is greatly increased. Since the L-854
controller is designed for outdoor, unattended, and continuous operation, it eliminates costly trenching and installation of
control lines to remote facilities.
