13. MANUAL MODE
Manual mode is used to manually control the light intensity. When the
controller is in manual mode, all light programs are stopped. When the
user exits manual mode, programming is resumed according to the
current clock time. If a power failure occurs while in manual mode, the
controller will resume operation at the same light intensity when power
is restored.
Turn the function selector until the MANUAL MODE pilot light turns
on. The current light intensity expressed as a percentage of full
intensity flashes on the display.
Use the adjustment knob to manually set the light intensity. Values
range from 0 to 100 % of full intensity.
14. ALARM CONDITIONS
An alarm is set off when one of the following situations occurs:
(i) the permanent memory chip is not working properly
(ii) a power failure occurs
(iii) the microprocessor is defective.
15. BACKUP BATTERY
A CR-2032 coin-type lithium battery is included with the controller. It is
used to power the internal clock in the event of a power failure. None of
the other functions will operate if this happens. When power is restored,
the VLC-3 will resume activation of the dusk-to-dawn programs and
peaks according to the current clock time.
