4.2 Uno Secondary Voltage Monitor (SVM)
!
DANGER! Risk of burns and permanent injury. Do not run lights out-of-water. Ensure the Focus light is submerged
before operation.
!
DANGER! Risk of electric shock. Power OFF equipment immediately if signs of physical damage.
How does the Uno Secondary Voltage Monitor (SVM) Work
Each Uno housing has its own secondary voltage (DC) monitor
observing the voltage output of the driver. The SVM has a pre-
programmed (built-in) range of voltages considered normal for
operation. Voltages outside of these parameters will trigger ERROR
mode, shutting off the Focus light. The SVM will indicate an error with
the Uno Indicator button flashing rapidly.
The SVM, will continue to
keep the affected Focus light OFF until BOTH:
a) the Error (out-of-voltage range problem) is resolved, AND
b) the SVM is reset
When is the Uno Secondary Voltage Monitor Active
The SVM is a feature of the Uno controller board. The controller board
requires mains power. The board begins working as soon as mains
power is turned ON. Note, the board must be powered for the SVM
feature to work, and to perform other controller functions.
How do I determine the status of the Uno SVM
See 4.3
Uno Indicator Button Status.
How do I reset the SVM once I have resolved the issue.
Push the flashing Uno Indicator button to reset the SVM. If the voltage
issue is resolved, the Focus light will return to its previous brightness
state.
How does a power outage or a power cycle of the Uno affect the
controller and Focus light?
The controller does not save its state when powered off. This means
a Focus light coming up from a power outage will always run an
automatic soft start – going through its usual 30 minute ramp up
from 10% to 100% brightness. However, if an error is detected during
ramp up, and the error is then resolved and the SVM reset (see above),
then the SVM will bring the Focus light up to the correct ramp level.
Similarly, if a light is replaced after ramp up and then reset then the
light will hard start at 100% as the powered SVM remembers its
programmed light output level.
