Introduction

The Berchtold CHROMOPHARE® C-570, C-571, C-572, C-450, and C-452 represent a modern generation of surgical lights, featuring many technological advances.

They are characterized by state of the art electronics, a computer designed polygon reflector, and cardanic suspension of the light head.

This includes the following benefits:

•Freedom from shadows in the operating field.

•High luminous power which generates the brilliance and high color temperature simulating noontime brightness on a cloudless day.

•Easier hygiene due to smooth styling of the light body – the absence of control knobs on the outer surface, the use of metal and safety glass, and the sealed light head.

•Larger range of height adjustment; greater mobility of the light.

•Easy replacement of defective halogen or Xenophot bulbs by OR staff.

•Cool, single bulb technology, with automatic, instant –on back-up bulb.

The construction of mechanics and control functions will be described in detail on the following pages. Diagrams and electrical specifications accompany the descriptions.

Installation and mounting instruction manuals are included to aid in the mounting and electrical installation.

Hospital Responsibilities

The hospital, or the hospital’s contractor, must complete the following items before Berchtold’s installation technicians arrive:

1.CFWP box (wall control unit) installed either by recessing in the wall, or surface mounting it.

SEE PAGE 7

2.SK box (contains transformers; used with low ceilings) installed either in the ceiling, or in an area accessible to the technicians.

SEE PAGE 8

3.All conduit installed and all necessary wires run. Make all connections in CFWP and SK box. Conduit from SK box needs to have 18 inches of flexible conduit and wire hanging out of ceiling at mounting plate.

4.Superstructure must be complete, and tested to withstand the maximum torque of the light.

5.Light mounting plate must be installed to the superstructure making sure that the plate is flush with the finished ceiling.

6.All painting must be complete with finished flooring installed.

Wall Mounted Intensity Control Box

Berchtold’s electronic intensity controls consist of two separate entities – a wall control box containing electronic circuits to vary the voltage to the transformers which Berchtold Corporation refers to as a CFWP box and a “SK” box containing one to three step down transformers that power the lights.

CFWP CONTROL BOX

This control box has space to house electronics necessary for the operation of up to three lights. Since two lights are the norm, this is what will be discussed. This box may be installed on the surface of the wall or it may be recessed. A trim ring is supplied to assist the installer when recessing is desired. The front of the box contains two 4-amp on/off circuit breaker switches, which light up when in the ON position and two knobs for controlling the intensity of the lights. To gain access to wire the electronics, loosen screws in each corner and allow the front door to hinge at the bottom. The only part of the interior that an installer needs to be concerned with are the small wiring blocks located at the top of each circuit board. Even if there are three circuit boards, the factory has wired them together so that only one power connection is necessary to power all of the lights. Close examination of the wiring blocks will show from left to right, two connections marker L1 and L2, two that have the factory installed “jumper” wires and two with a schematic symbol of a transformer. The installer need only connect the power to L1 and L2 and run two pairs of wires from the terminals with the “symbol” of a transformer to one of the two ceiling mounted transformers in accordance with the installation instructions. WARNING: ALWAYS RUN A GROUND WIRE.

If the transformers are mounted on the flange of the ceiling tube, which also holds the light, the installer need only connect the “transformers” wires from the CFWP box to the input side of the fused junction block. The rest of the wiring on this particular installation was accomplished at the factory.
