Power Adjustment
The product control system incorporates electronic power limiting. The power limit
parameter OP.Hi is accessible to the operator and can be used to adjust the product to
the actual supply voltage.
Some models covered by this manual are fitted with 208 V elements and are designed
for use over the range of voltages 200 V- 250 V; the power limit parameter is set
accordingly. These models may be relocated to a different voltage within the range: the
power limit should be reset to match the voltage.
To check whether the furnace is a 208 V model:
look at the OP.Hi parameter
l
make a note of the value and compare with the 9.0;
l
observe the rating label; if a range of voltages is stated, it is not a 208 V multi
l
voltage model;
if in doubt, check with Carbolite Gero – each product has its own record card.
l
Refer to the controller instructions for how to change the power limit.
4.9 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.
