Specifications
28 Revision 4 – 1-7-2008 FTB 312-4
Replacement
1. Align the pins on the flashtube base
with the clamps of the terminal screw
lugs, making sure that the red dot on
the flashtube base coincides with the
red dot marked on the bracket directly
under it.
2. Carefully insert the flashtube and settle
it into place, making sure the ceramic
base is resting directly on the tops of
the screw lugs.
3. Secure the flashtube by tightening the
three screws on the screw lugs.
Trigger Transformer (T101)
Use the following removal and
replacement procedures:
Removal
1. At the trigger wire post adjacent to the
flashtube, remove the large diameter
wire coming from the trigger
transformer.
2. At one of the smaller, side-mounted
ceramic posts, remove the small wire
to the trigger transformer. Do not
disconnect the primary winding wires.
3. Remove the two 4-40 x 2" Phillips®-
head screws holding the transformer
assembly to the bracket. Note the
orientation of the molded secondary
winding with respect to fixed features
on the bracket, since it must be
reinstalled with this same orientation.
4. Remove the outer half of the core and
lift off the molded secondary winding.
The primary winding will remain
hanging in place.
5. Remove the inner half of the core.
Replacement
1. Reassemble the primary and secondary
windings over the two halves of the
core. Attach the core to the bracket
using the two long screws.
2. Reattach the wires.
Trigger Coupling Transformer
(T102)
Removal
Removal and replacement are similar to
the procedure for the Trigger Transformer
(T101).
Operational Checkout
This section describes basic functional
testing.
Observe the response of the equipment as
indicated in Figure 3-1. If the system
contains more than one light, and the
lights are interconnected for master/slave
synchronization, perform the actual
checkout steps described below only at the
master unit. However, observe all lights
for responses. These procedures assume
that the following conditions are present:
1. The photocell is subjected to normal
outdoor daylight.
2. All installation steps in Installation
Checklist have been completed.
3. PCB1 is correctly programmed.
