Power Adjustment (Thyristor)
The current-limiting thyristor stacks which control power to the elements are fitted with
an adjustable resistor which is factory set to limit the maximum current supplied. In the
event of a change of supply voltage, or the fitting of a new thyristor, further adjustment
may be required.
The maximum element currents for this model are listed in section 11.0. Please contact
Carbolite Gero for further information.
7.8
Low Voltage Compensation
If the supply voltage proves to be routinely below the nominal figure for which the
furnace has been set up, there is a "+2%" position on the transformer primary side
which may be used instead of the standard position, see section 8.10.
