3 Installation
3.1
Selecting Location
The projector is designed for use in a normal workshop environment but should be sited as far away as possible from sources of grinding grit, oil mist and vibration. Choose a convenient location with a firm, level floor, where the screen will not be subject to glare from sunlight or artificial lighting. Make sure that a suitable mains supply is available, (see below).
3.2
Power Supply
The projector should be mounted on a bench, or on the optional stand supplied, so that the controls will be easily accessible.
Note: The bench must be firm, flat, and level.
A mains supply of the correct voltage is required.
WARNING: Check the mains voltage setting before connecting the mains supply (see 3.6 - Mains Connection ).
3.3
Moving the Projector into Position (Figure 1)
Insert lifting bars though the holes in the frame and lift the projector using suitable equipment. The weight of the unit is approximately 180kg, (397lb). CAUTION: Do not attempt to lift the unit by the projection lamp cover or screen housing.

3.4
Removing Transit Straps (Figure 2)
The transit straps are painted red.
CAUTION:
The transit straps must be removed before any attempt is made to move the workstage or to use the projector.
Remove all transport straps (pictured below) fully before use

3.5
Fitting the DRO (Figure 3)
1. Fit the bracket to the projector, securing it with the four screws A.
2. Fit the DRO to the bracket, securing it with the two screws B.
3. Ensure all cables are connected in the appropriate connectors.
Projectors fitted with Edge detection:
4. Fit the reference cable and screen cable connectors to the corresponding sockets at the back of the DRO. 5. If an optional x50 or x100 projection lens is to be used, screw the diopter supplied on to the condenser lens assembly (on the face of the projection lamp cover nearest the screen, see Section 6 - Maintenance, Figure 7 , item 9 ).

Mains Connection
WARNING:
A secure earth connection must be provided. The cable colour code is as follows:
Brown/Red
: Live
Blue
: Neutral
Green/Yellow
: Earth
The mains voltage is factory set to the correct value for the local supply; however, it is recommended that the setting is checked before power is applied.
3.7
Commissioning Checks
Make the following checks before putting the projector into service, referring to Section 5 - Operation as necessary:
1. Make sure that the projector is secure and level on its bench or stand.
2. Fit a workpiece securely to the workstage.
3. Switch on the power supply.
4. If a digital protractor is fitted, check that the displays and indicators light up for approximately one second.
10
HD400 and HB400 Operator ’ s Manual
5. Check that the DRO screen shows a display.
6. Switch on the profile illumination and turn the focus (Z-axis) handwheel to bring the workpiece into focus. Check that the screen image is satisfactory.
7. Switch on the surface illumination, and check that the fibre optic light guides are lit; (HD400: three guides, HB400: two guides).
8. Release the latch block on the X-axis slide, check that the slide moves freely, and apply the latch. 9. Operate the X and Y axis controls and check that the workstage moves freely: (projectors with manual workstage controls: X and Y axis handwheels, projectors with motorised workstage drive: joystick).
4 Description of Equipment
(Figure 4)
The Starrett HD400 and HB400 Optical Projectors are designed for 2- dimensional optical measurement of profiles and surface features of parts.
Fig.4 (HB)

Fig.4 (HD)
The projector comprises the following main items:
1
Screen Housing
The housing contains the projection lenses (7), mirrors, surface illumination light guides (8), and the mains transformer.
2
DRO
The DRO enables measurements to be viewed and recorded, and programs to be created for measuring a number or similar parts. For further details, refer to the DRO Operators Manual.
3
Projection Lamp Cover
Houses the projection lamp, condenser lens, and surface illumination lamp.
On a projector fitted with an edge detector , the diopter lens supplied is attached to the condenser lens if an optional x50 or x100 projection lens is in use. The diopter intensifies the light beam to provide a good light-to-dark reference for the edge detector.

Work holding Equipment.
Work holding accessories are available, please refer to work holding accessories catalogue on the Starrett Website
5
Workstage
Movable in the X and Y axes for measurement, and in the Z axis for focus, with two dovetail slots for fitting work holders with angular clamping screws. The dimensions are as follows (in mm):
6
Surface Illumination Light Guides
Optical fibre guides which conduct the light from the surface illumination lamp for surface illumination of parts. (See Section 5 - Operation - Controls ). The HD400 has three guides; the HB400 has two.
7
Projection Lenses
The lens projects the image on to the screen via the two mirrors in the screen housing (1).
The HD400 has two lenses mounted on a slide; the HB400 has a single lens . A range of lenses is available; for details see Section 7 - Specification .
For changing lenses see Section 6 - Maintenance .

Y-Axis Handwheel
Raises and lowers the workstage.
7
Focus Handwheel
Moves the workstage along the Z-axis for focusing.
8
X-Axis Handwheel
For fine adjustment of the workstage along the X-axis.
9
Surface Illumination Light Guides
Provide surface illumination for measuring surface features of flat components. For the optimum illumination, pull out the guides and position them as close to the component as possible. The guides provide a 'cold light' source; minimal heat is radiated to the component. For components with a directional surface finish (such as ground faces), the surface texture should be vertical to give the brightest image on the screen. HB400: Slacken the clamp screws, and retighten them after positioning the guides:

Cleaning Lenses
CAUTION
Do not use polishes, or window cleaning aerosols and liquids for cleaning lenses.
Do not touch the inner surfaces, (those facing away from the workpiece), of the projection or condenser lens. The projection lens is the most critical; a finger mark on the inner surface will degrade the quality of the projected image.
Remove any accumulated dust with a photographic lens brush.
Remove any grease or finger marks with a new photographic cleaning tissue, which may be moistened with Isopropyl Alcohol if necessary.
6.3
Cleaning the Mirrors
CAUTION
The mirrors should be cleaned as infrequently as possible. It is recommended that cleaning is performed by service engineers.
Do not touch the surface of the mirrors.
HD400 and HB400 Operator ’ s Manual

6.4
Cleaning the Screen
CAUTION
To avoid damaging the screen markings, do not use excessive pressure when cleaning the screen.
Clean the screen ONLY with Isopropyl, this is an alcohol-based glass cleaner.
And wipe gently with a soft cotton cleaning cloth.
DO NOT USE FORCE!
6.5
Changing the Projection Lenses (Figure 7)
CAUTION
Do not touch the surfaces of the lens.
1. Each lens is secured by a bayonet fitting. Rotate the lens anti-clockwise and withdraw it.
2. Fit the replacement lens, rotate it clockwise until it is secure, and check that the two red spots are aligned.
6.6
Lubrication
Periodically lubricate the slides with light oil.
6.7
Latch Block Adjustment (Figure 8)
The tension of the latch block on the X-axis slide latch may require adjustment after a period of use. If necessary, re-set the tension as follows:
1. Withdraw the end cap (the cap is a push fit).
2. Unscrew and remove the engagement handle.
3. Insert an Allen key into the socket lock screw, slacken the screw, and hold the internal nut in position with the key.
4. Rotate the bearing mount/collet to give the required tension.
5. Tighten the socket lock screw.
6. Refit the engagement handle and end cap.
