STARLITE/SENTINEL FOOTSWITCH MODIFICATIONS

The Footswitch that is available for the ZBE Starlite Colorhead and Sentinel Enlarger is designed for use in almost all darkroom environments. At times, however, a user will want the footswitch to operate in a slightly different manner than originally designed. This document covers two modifications that can be done to the Footswitch assembly that can accommodate that following:

 Change operation of Focus Footswitch to yield filtered light, instead of white light:

This is sometimes desirable so that, when the user activates the Focus Footswitch, the light will shut off immediately upon release of the pedal. In original configuration, the Focus Footswitch will turn the light on in white-light ("FILTERS OUT") mode. When released, the light must return to normal filtration before extinguishing. This delay of about 3-4 seconds can be annoying to some users.

 

 Swap the positions of the Focus and Expose Footswitches:

If it is desired to change the locations of the Focus and Expose Footswitch pedals, the procedure for this is described at the end of this document.

Changing Operation of FOCUS footswitch from White Light to Filtered Light:

This modification involves some soldering at the connector of the Footswitch assembly (where it plugs into the Starlite/Sentinel). The tools needed will be:

• 60W Soldering Iron (one designed for use on electronic circuits, not pipe fittings)
• Solder (Electronic-grade Rosin core, not acid-core)
• #1 Size Philips-Head Screwdriver
• Small razor, scalpel or X-Acto® knife

The procedure is as follows:

1. Unplug the Footswitch from the enlarger.
2. Loosen and remove the three screws holding the connector housing together. See drawing of connector at right.
3. Note the orientation of the connector hood, then remove it.
4. Examine the wires going to the terminal of the D-25 Connector. They should appear as shown below. The functions of the three wires are also indicated:
