a. Affix two 41n x lin x 161n (lOcm x 2.5cm x 46cm) wooden ballens horizonlallyonto the wall at
48in (122cm) vertical centres. See
the Diagram below. Ensure the two battens are both level and
paralleland that they are securely attached to the wall so that a lotal weight of approx 39kg. (65Ibs)
~
can be safely supported.

6. Colour 500 Analyser
When rlLLlng a Colour 500 Analyser, rererence should be made lo the separate manual supplied ror both
ritting and rulloperating inslruc.llons.
7. Eleclrlcal COMections
AdetaiJedcharL showing the cOMec.lions or all eleclrical components is at Appendix 1 to this Section.
a. Ensure the enlarger eleclrical componenls are compatible lo the mains power supply to be used. A
smal/plate
or label will be attached to e8ch component giving the voltage, serial number etc., and will
normallybe allached to the underside or rear or the component.
b. When a Timer Is not being used in conjunction with the Transtab, the shorting plug supplied with the
Transtab must remain rIlled ror operation to be possible, as shown in the diagram at Appendix I to
this Section.
8. Filling
the liQhlsource
All types or Jightsources available ror the 504 series or enlargers are rully interchangeable. the method
or mounUng and attachment to the enlarger being common to all.
a. Ensure that both Lens and Negative Stage rUMer locking knobs are nrmly locked. This Is essenUalto
avoid unc.onlrolledupward movement or the runners and possible damage to the equipment.
b. Release the lert hand locking knob and wind the Lens Stage runner down as rar as It will go using the
lerthand conlrol wheel then nt-Iock.
c.
Using one hand to support the Negative Stage runner, thererore preventing rapid upward movement.
release the right hand drive locking knob and bring the negative stage down to a convenient working
height then tighten the locking knob securely. Remove the wooden wedge rrom the lop or the column.
Repeat ir necessary lo obtain a convenient working height.
VeeGuldes
d. Remove the lransit tape retaining the Iirt pins and
lighlsource tension spring In position on the negaLlve
stage.
e. Lirt
the Jighlsource and position so that the two
rollers on the hanger casting at the rear or the
lighlsourc.e housing enter the cast V' shaped
recesses In the rear or the Negative stage runner
back plale.
r.
Connect the tension spring to the rear panel or the
Iighlsource by placing the upper hole in the metal tag
over the head or the screw provided. This prevents
movement or the IIghlsource on the stage as It Is
raised and lowered on the column.
g.
h.
Attach the lighlsourc.e cable to the cable clip located
on the rear or the column.
Figo.
The rour nylon rollers located within the Negative Stage back plate are levelling rollers ror squarely
sealing
the Jighlsource when in position. These are factory adjusted and will not require attention
unless
the lighlsource is continually being mled and removed. The method or fldjustment Is rully
explained in Section o.

4. Correction Tilts
All models of the 504 have a correction Ult racillty fltled to both the negative and lens stages. Click
slops are Ilsorltted to both stages to ensure the positive return to the central. level. operating position.
Each of the two stages has Its own locking lever, on the lens stage this Is located In the centre or the
casting on the rront face. and on the negative slage, It Is sltualed on the lert hIIIld side or the rooner
casting
Immediately behind tne 11ft pins operating lever.
a.
To tilt either of the stages. release the locking lever by rotating In an MtI-clockwlse direction.
Adjust the
degree of tiltrequired then re-apply the locking lever.
b. 80th locking levers .... keyed to their shafts by spllnes and if. for ease of operltion. it Is required
to chMge their positions. release the lock. pull the lever away from its shart then re-engage the
spllnes into the desired poslUon.
5. Negative Carrier Lift Pins
The locaUon of the two lift pins is shown in the Diagrllfll at paragraph I to this Section. These two pins.
that protrude from the negative stage casUng, are operated by the long lever on the lerthend side of the
negative stage. 8y pushing this lever. therefore raising the pins. the complele IIghlsource is raised
allowing the Negltlve carrier to be Inserled Into position. 8y puJllngthe lever back towards the front of
the enlarger the pins will retract thererore allowing the lighlsource to lower onto the carrier retaining It
firmly
In position.

6. Leos and Negative Stage Adjusting Wheels
The two large black. handwheels situated at the front of the enlargercontrol the movement of the leos and
Negative Stages. the left handwheel controls the lens stage and the right hand one the Negative stage. At
sither side of the bass of the column are the two locking k.nobs for each of these handwhesls. It is mosl
important thal
both these are in the locked position whenever movement of the lwo stages is not tak.lng
place and in particular when changing lightsources. These conveniently situaled handwheels are
positioned to aid operation and in particular make focusslng easier than on conventional enlargers. Ills
recommended thal a focussing aid be used for the best results and these are available from De Vere.
7. Transformer/Stabilizer (TRANST AB)
The De Vere 504 TRANSTAB Control Box has two switches marked Mains' and focus' located on the
rront panel. The Mains' switch should always be In the '00' position when the enlarger is in use.
therefore
providing the mains electricalcurrent to the TRANST AB. The focus' switch. when in the '00'
pOSition, will bring the Ilghtsource Into operallon. this switch should remain switched orr when used with
the Electronic Timer or In conjunction with the Colour 500 Analyser. A detailed wiring instruction
chart
showing all wiring connections Is appended to Section Three. Two versions of the 504
TRANST AB are available. the 250 watt. ror use with the single lamp Mark 4 Dichromat and the 500
Watt. for use with the twin lamp Mark 5 Dichromat.
a. Fuse Replacement
Special Anti Surge ruses are used In this component and spares. when required. should be requested
rrom your De Vere local agent.
B. Universal Timer (Nol required with Colour 500 Analyser)
The layout of the Universal Timer Control Panel Is shown in the diargam below. At the top of the panel
are three black knobs each with a dial. marked 0.1. 1 and 10 seconds. and graduated from 0 - 9 In 0.1
secs. 1secs and 10 secs respectively. thererore allowing I maximum exposure time of 99.9 secs to be
pre-set. The timer Is a rree standing unit and a faclllly has been Included to allow the Conlrol Panel to be
tilted for ease or operation. The black knobs on both sides or the unil can be released and tightened
to eTrect this tilt. Located on the lower portion of the conlrol panel are three switches. these are:
a. Power
This provides power for the Timer and must be switched on whenever the Timer is in use.
b. Focus
When In the On position provides a constant light rrom the IIghtsource with which to rocus. When the
rocussing has been completed return the switch to the orr posllion.
c. Expose
A momentary switch. that when pressed. wllllnlliate the complete exposure sequence switching the
IIghtsource on ror the period set on the elclronlc timer.

9. lens Panels
To cover the normal rlnge or lerases ror the 504. three types or lensmotllUng panel are required. The
application or each or these panels is shown in the table at Appendix I to this SecUon. The lens panels
ILLach to the lens sLage with I blyonet type connector. The two pllsUc coIled bosses. which Ire
recessed Into the stage. occlSslonally require minor adjustment when panels are continullly being
connected or dlscomected. Instructions ror this adjustmenlare conLained in Section Six.
10. The ColUIM
The ColUIM has been maoorldured rrom the highest grade Ilwniniwnto ensure rigidity ror the lire or
the enlarger. Q'I the rorward race or the Column are both Imperlll and Metric sclles to aid rapid
re-posltioning
or the lens end negltlve sLages. SLainless slatl V guides ItLached to the colt.mn ensure
many years or very precise operltlon or both Stages.
