Q: Can I vary the Intensity of the Lights?
A: Yes. Each Light is individually dimmable.
Q: Can I vary the Flash-Rate of the Lights?
A: Yes. The Flash-Rate can be varied from 2 to 10Hz.
Q: Can I drive Multiple Lights off of ONE Light1 or Light2 Output?
A: Yes, as long as the total combined Watt-load does not exceed 150-Watts.
Q: Can I have only ONE Light Flash while the other Light Remains ON?
A: Yes. This is defined as the Flash-Mode and can be set at order time, or
by jumper
configuration by the user. Please
see the JBTLF Manual for more information.
Q: I would like to use a 12V Rated, 150-Watt Light; is this a problem?
A: Yes it is. The JBTLF Module is rated to handle 150-Watts per Lighting
Channel
(Light1 and Light2). A 12V rated Light, however, is actually a load of
204-Watts at
14V. This is more than 33% over the rated 150-Watts. If you require
150-Watts,
please try to find a Light that is rated for 14V.
Q: I want to use multiple JBTLF Modules; can I have them flash at the same
time?
A: Yes. Each module, with the connection of a single wire, has a
Synchronization
feature that allows the Modules to flash in sync with each other. Please
see the
JBTLF Manual for more information.
Q: Will shorting the Light Outputs damage the Module?
A: Under normal circumstances, NO. There are cases, however, that could
damage
the driving capability of the module. This can occur when the outputs or
V+ supply are
shorted to a High-Voltage (35V or greater) for a period greater than 1/5th of a
second.
Q: Can I connect only one Status-LED and still see the status of
both Lights?
Yes. The JBTLF Module automatically senses the number of LEDs
connected and
adjusts its status display accordingly. Please see the JBTLF Manual
for more
information.
Q: Can I drive both the Light On Functions and the Flash Functions
from a single
switch?
A: Yes. Using a DPTT (Double Pole Triple Throw) Switch such as Digikey
Part Number
CKN1133 (http://www.digikey.com), you can wire the switch function to be
OFF-ON-FLASH. Please see the JBTLF Manual
for more information.
Q: Can I dim the LED Outputs for Night-Flying?
A: Yes. The JBTLF Flasher has a Panel-Light Input that automatically
senses when the
Panel Lights are turned on. When the Panel Lights are active, the LEDs are
dimmed in
proportion to the dimming of the Panel Lights. A 'fine tuning' adjustment
is available
through the top of the unit (labeled PANEL ADJ). Please see the JBTLF Manual
for
more information.
Q: I would like to control multiple modules off of a
single control switch. Is this
possible?
A: Yes. Each of the control inputs (LIGHT1, LIGHT2, FLASH) can be tied
together with
other modules. Some care will be needed on the choice of
variable-resistors for selecting
the Flash-Rate and Dimming (if required). Please see Appendix D in the JBTLF Manual
for resistor values versus the number of inputs connected.
Q: How much
airflow does the module need when driving 150-Watt Lights?
A: When driving two 150-Watt Lights, the JBTLF Module dissipates around
3-Watts
(less than the average night-light!) Most mounting situations (behind the
Instrument-
Panel, on a Bulk-head, et cetera) will offer more than adequate airflow.
But in certain
situations, the installer may want to take some additional care. These
include:
