WARNING IMPORTANT
This appliance must be earthed.
The wires in the mains lead are coloured in accordance with the following code:
Green and yellow
Earth
Blue
Neutral
Brown
Live
If the plug provided is unsuitable for your socket outlets, the plug must be cut off and suitable
plug fitted. The cut-off plug should be disposed of and must not be inserted into any 13 amp
socket as this can result in electric shock. The plug or adapter of the distribution panel should be
provided with 13 amps fuse. As the colours of the wires in the mains lead of this appliance may
not correspond with coloured markings identifying the terminals in your plug, proceed as follows:
The green and yellow wire must be connected to the terminal in the plug which is marked with the
letter E or by the earth symbol , or coloured green, or green and yellow. The blue wire must be
connected to the terminal which is marked with the letter N or coloured black. The brown wire
must be connected to the terminal which is marked with the letter L or coloured red.
NOTE
After replacing or changing a fuse, the fuse cover in the plug must be replaced with a fuse cover
which corresponds to the colour of the insert in the base of the plug or the word that is embossed
on the base of the plug, and the appliance must not be used without a fuse cover.
Only 13 Amps fuse approved to B.S 1362 A.S.T.A. should be used.
4. Technical description
4.1 Front panel
The front panel consists of an alphanumeric display, a keyboard with 9 membrane keys, a light emitting
diode (LED) that lights when voltage is applied (HV on) and connectors for two electrophoresis units.
4.1.1 Display
A 32 digit alphanumeric display guides you through the programming, shows current parameter values
during the electrophoresis and final parameter values afterwards. It also asks questions and shows error
messages. The display has an upper and lower row.
Fig. 1, see inside front cover, shows the display in the start position when power is switched on. The
mode (in this case SET) is shown in the upper row on the left. The program number, the chosen way of
controlling (step or gradient) and the phase number are shown in the center of the upper row. The
program number shown is that of the previously entered program. The blinking figure, in this case “1”,
indicates that it can be changed by using the
Ô
/
Õ
keys. The default way of controlling the power supply
is by step programming ( ). The upper right shows the programmed breakpoint for the actual phase. In
this case it is 0:00h. The lower left, middle and right positions show voltage, current and power
respectively, which all are zero for an unused program.
