Introduction
This instrument is manufactured with the latest technology and needs no particular maintenance. Consort certifies that this instrument was thoroughly inspected
and tested at the factory prior to shipment and found to meet all requirements
defined by contract under which it is furnished. However, dimensions and other
physical characteristics may differ.
The normal operating temperature should be between 0 and 40C. Never use
the instrument in a room with high humidity (>95 %) or at very low temperatures
(condensation water!).
Connect the instrument only to an earthed power line. The required power source
is indicated on the label at the back of the instrument. Do not cut and splice the
power cord. When removing the power cord from the wall outlet, be sure to unplug
by holding the plug attachment and not by pulling the cord. Do not hold the plug
by wet hand.

Very important
This electrophoresis power supply is a high technology instrument available in
several versions. As it is capable of giving dangerous voltage levels by which high
power is involved, we suggest that you take a few moments to read this manual
thoroughly. Although this instrument is equipped with all necessary safety features
against abuse and other accidental failures, caution should be exercised when
working with high voltage equipment.

Avoid to touch the outlets with any conducting object and make sure there is
a second person present for your safety in case of any severe electric shock.

Never touch any part of the assembly (power supply, leads or tank) before having switched off.

Never manipulate with wet hands.

Do not ground any of the outputs or the buffer in the tank.

Connect the outlets only to an insulated electrophoresis tank with safety

cover.

Never make any other connections, such as e.g. putting several power supplies
in series or in parallel.

In order to prevent electric shock, never open the back plate nor remove the
cover.

Do not expose the unit to rain or any other liquid.

Do not spill liquid or insert metal objects inside the unit.

Take care so that the power supply is not dropped to avoid damaging the cabinet which defeats safeguards or injuring yourself.

If the unit has been dropped or the cabinet has been damaged, unplug it
and have it checked by an authorised service technician to restore the safeguards.

The fact that the unit operates satisfactorily does not imply that the unit is
properly earthed or that it is completely safe. If in any doubt about the effective earthing of the unit, contact a qualified electrician.

Never block the ventilation holes or place the unit in any enclosure unless
proper ventilation is provided.

Never place the unit near or over a radiator, heat register or stove.

Avoid locations where the instrument is exposed directly to the sun light.

Method programming permits to store up to 9 different methods, each
with 9 steps, of frequently used parameters in the non-volatile memory
for future recall. Each step is able to recall a next one, providing a flexible multiple step function for special techniques. The method mode also
permits to program a linear voltage gradient for any step provided the
limiting current or power is not attained. Parameters can be changed
temporarily without interrupting the run.
1. Verify if the instrument is switched off.
2. Connect the electrophoresis tank to the instrument.
3. Switch the instrument on. If the timer is still running after switching
on, the power supply will automatically proceed with the experiment for the remaining time. Press STOP (within 10 seconds) if you
want to go in stand-by during the run. The parameters can then be
changed eventually. Press RUN to proceed with the experiment or
press SET, during 2 seconds, to go in stand-by again.
4. Select the METHOD mode and press SET.
5. Select the desired method and press SET.
6. Select the desired step and press SET.
7. Decide whether or not a voltage gradient has to be performed and
press SET.
8. Enter the desired voltage limit and press SET (= the voltage end
point in case of a gradient step).
9. Enter the desired current limit and press SET (this limit is automatically set to maximum and cannot be changed in case of a gradient
step).
10. Enter the desired power limit and press SET (this limit is automatically set to maximum and cannot be changed in case of a gradient
step).
11. Enter the desired time-units (h of kVh) and press SET.
12. Enter the desired time and press SET.
13. Decide if the experiment should automatically proceed with a next
step (resuming from point 6) or stop after this step. Enter the
desired procedure and press SET.
14. Press RUN to start the experiment.
At any time, you can return in the stand-by mode by holding SET pressed during 2
seconds.
At any time, you can avoid programming unnecessary parameters. To do so, simply
press RUN instead of SET after entering the last relevant value and the instrument
will immediately start the experiment keeping the other parameters to their previous values.
To ensure that the desired parameter is kept constant, we suggest to pre-set all
other parameters to maximum.
A blinking unit of the controlling parameter appears when the regulation is complete.
The timer will always count down.

Frequently Asked Questions

What are the relations between Voltage, Current, Power and Resistance?
Power (W) = Voltage (V) x Current (A)
Resistance () = Voltage (V) / Current (A)
How does a power supply react after pressing RUN?
The internal generator will start building up the high voltage at the output terminals while voltage and current are constantly measured and power calculated.
When one of the pre-set parameters is exceeded, the generator stops and will keep
that parameter constant.
How important is the resistance of an electrophoresis unit?
The resistance of an electrophoresis unit depends on its size, gel thickness, amount
of buffer, buffer conductivity and temperature. This resistance will normally decrease in time due to a slowly increasing temperature. Electrophoresis units which
have a resistance below the minimum load resistance of a power supply will trigger
an alarm! Read the output voltage and current during a run to measure the resistance and use above formula to calculate the value.
How to keep a constant voltage during a run?
Program the desired voltage and a higher current and power then the maximum
expected values:
Current > Voltage / Resistance
Power > Voltage x Current
How to keep a constant current during a run?
Program the desired current and a higher voltage and power then the maximum
expected values:
Voltage > Current x Resistance
Power > Voltage x Current
How to keep a constant power during a run?
Program the desired power and a higher voltage and current then the maximum
expected values:
Voltage > Current x Resistance
Current > Voltage / Resistance
Why are my output values different from those of a similar experiment?
Either your programmed parameters are not equal to those described or the resistance of your electrophoresis unit is different (see above). It cannot be due to e.g.
an other model of power supply as the relations between Voltage, Current, Power
and Resistance are monitored in the same way by any instrument (the electrical
laws cannot be disregarded!).
What about connecting more than one unit to the same power supply?
The outlets being in parallel each electrophoresis unit will be supplied with exactly the same voltage. However, current and power may differ due to differences
between them even when exactly the same model, gel, buffers, etc... are used.
Therefore, it is recommended to run several electrophoresis units only in the constant voltage mode on the same power supply.
