Power Adjustment

The control system incorporates electronic power limiting. The power limit parameter
OP.Hi is accessible to the operator and can be used to adjust the furnace to the actual
supply voltage.
The models covered by this manual are designed for use over the range of voltages 200
V - 250 V (or, if ordered, 100 V - 125 V), and the power limit parameter is set
accordingly. These models may be adjusted to a different voltage within the range: the
power limit should be reset to match OP.Hi, see 12.0
Refer to section 3.0 for power adjustment instructions.

7.9 Running at Low Temperatures

The power limit may be adjusted to a low level in order to achieve better control when
operating the product at a low temperature. Before changing the power limit, record
the default settings for possible future use. Refer to the Power Settings section of this
manual for default power limits. If the product fails to reach the desired temperature,
refer to the Temperature Controller and Fault Analysis sections.
