ALTANA BYK 2710 - Manual (Page 2)

IMPORTANT
The wires in the mains lead supplied with this appliance are coloured in accordance with the following code:
Green and Yellow : Earth Blue : Neutral Brown : Live
As these colours may not correspond with coloured markings identifying the terminals in your plug, connect
as follows:
Green and Yellow wire to the terminal marked with the letter E or by the earth symbol or coloured green
and yellow.
Blue wire to the terminal marked N or coloured blue.
Brown wire to the terminal marked L or coloured brown.
WARNING: THIS APPLIANCE MUST BE EARTHED.
It must be fitted with a 3 pin plug and only connected to an a.c. supply having a voltage corresponding to
that marked on the appliance. When a fused plug is used, it should be fitted with a 3 amp fuse, if in doubt
consult a qualified electrician, since these instructions must be observed.
Use the recorder on a firm bench and do not restrict ventilation by using in a confined area.
Any surplus paint should be wiped off the recorder with a dry cloth. We do not recommend the use of
solvents.
If an object is accidentally dropped into the recorder, immediately disconnect from the main supply and
retrieve the object. If the equipment has been dropped or damaged in any way, it should be checked before
connecting to the supply. Similarly, although the equipment is lubricated for life, any work (especially
involving the removal of covers) must be carried out by a competent service engineer.
In the interests of safety, always use the equipment in the specified manner.
OPERATING PROCEDURE
1. With the Recorder switched off, place the glass test strips in their holders on the top of the recorder
and clamp a needle into each needle holder making sure that the needle arm is horizontal when the needle
end is resting on the glass strip. If it is necessary to move the needle carrier in order to bring the needle
directly over the glass strip, first lift the release lever on the back of the needle carrier (BK 3 model) or
depress the plunger on the top of the needle carrier (BK 6 and 10 model) and slide the carrier to the required
position.
2.
Raise the needle holder arms so that the needles are lifted off the glass strips and position the arms
against the back-rest. Slide the needle carrier to the start position at the zero end of the time scale.
3.
(BK 3 model only). The required travel time is obtained by turning the selector knob in a clockwise
direction and sliding it in or out to expose the desired travel time and then releasing the knob.
4.
Remove the glass strips and apply a paint film to them (our Applicator cube and Casterguide are
recommended for this) and replace them on the Recorder.
5.
Lower the needles onto the test strips and switch on at the main switch (marked O/I).
(Note: BK 6 and BK 10 models only. Each switch on the top cover alongside the glass strips operates the
pair of needle carriers to which it is closest. Switch on these switches as required.) The needles will now
commence their run along the glass strips and automatically stop at the end of their travel, (a few millimetres
before the end of the time scale.)
6.
Switch off the Recorder and remove the glass strips for analysis.
THE BK DRYING RECORDERS
BK 3
The BK 3 speed Drying Recorder has been used widely in the coatings industry throughout the world
for several decades. A needle carrier holding six hemispherical ended needles travels the length of the
six 305 x 25 mm test strips in 6, 12 or 24 hours. Other speeds are available to special order. A time
scale on the side cover is graduated to suit the three different travel times.
BK 6 BK 10
The BK 6 and BK 10 Recorders have independently operating tracks allowing tests to be made at
different start times. Pairs of tracks operate at the same speed, and a wide range of travel times are
available. Travel times of 6, 12, 24 and 48 hours are all considered as standard. A time scale on the
front cover is graduated to suit the instrument’s drying time ranges. Each pair of tracks has its own
individual operating switch.
