3. Loosen, but do not remove, the screws holding
the HV rectifier board to the terminal block
TB3. Slide the circuit board out from under
the terminal block screws.
Replacement
1. Slide the circuit board under the terminal
block screws and tighten them.
2. Replace the Red Light Module.
3. Verify that wiring matches the Information
Card and restore the wire routing to its origi-
nal state.
PCB4 Sense Module
Removal and replacement are similar to those in
Section K2 Mode Relay.
Red Light Module
Removal
1. Remove the external wires connected to TB5.
2. Unplug all harness connections to the Red
Light Module.
3. Loosen two screws in the base that fasten the
Red Light Module to the base.
4. Remove the Red Light Module. Be careful of
components and connectors.
5. Disconnect the ground wire from the back of
the module.
Replacement
1. Replace the Red Light Module in the reverse
sequence to that of Removal.
2. Verify that wiring matches the Information
Card and restore the wire routing to its origi-
nal state.
R2A and R2B Burst Resistors
Removal and replacement are similar to those in
Section K2 Mode Relay.
T1 Power Transformer
Removal
1. Remove the Input Power Module.
2. Remove the four screws holding the trans-
former to the base plate and remove the trans-
former.
Replacement
1. Replace the power transformer in the reverse
sequence to that of Removal.
2. Verify that wiring matches the Information
Card and restore the wire routing to its origi-
nal state.
T3 Trigger Coupling Transformer
Removal
1. Remove the Red Light Module.
2. Remove PCB1.
3. Loosen the four screws that hold the Compo-
nent Bracket to the base.
4. Slide the Component Bracket up off the
screws. Be careful of the cable and cable con-
nectors. You may hang the Component
Bracket over the edge of the connector panel to
perform the remaining steps.
5. Pay special attention to the orientation of the
wires on the transformer and their connec-
tions. Replace them in the same orientation.
Replacement
1. Replace T3 in the reverse sequence to that of
Removal. Note the connections to T3 as in
Step 5 of the Removal, and replace the wires
to their connections in the same way.
2. Verify that wiring matches the Information
Card and restore the wire routing to its origi-
nal state.
Flashhead
FT101 Flashtube (FH 306)
Removal
1. Manually lift the red filter to allow access to
the three screws under the flashtube that hold
the flashtube assembly in place.
2. Using a flat-blade screwdriver, loosen the
three screws (on screw lugs) directly under the
flashtube, which hold the flashtube connector
pins. Doing this enables you to disengage the
flashtube. Carefully lift the flashtube upward
from the assembly.
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 wire on the support col-
umn directly under it.
2. Insert the flashtube and settle it into place,
making sure the ceramic base is resting
directly on the tops of the screw lugs.
