5. Set of standard voltage (SF-7)
When the control unit or the relay unit is replaced, set the standard voltage, referring to following procedure. Because the control unit judges if the AC
supply voltage is 240V+10% or 230V-12% by comparing with the standard voltage. The temporary standard voltage is set when the oven is shipped
from the factory. But when the control unit is replaced to new one, it does not have the standard voltage. When the relay unit is replaced to new one,
set the standard voltage too. Because the signal from the relay unit to detect the AC supply voltage has error of
±
5%.
The standard voltage can be set by using this function. For this model’s standard voltage is 230V.
For example: Procedure to set the standard voltage (in case input voltage is 230V
±
1V)
For example: In case that AC supply voltage is out of range from tentative memorized voltage (240V +10% ~ 230V-12%), the display will
show “----” as follows.
At that time, the voltage of AC power may be not suitable or the control unit and /or the relay unit may be out of order.
For example: Procedure to set standard voltage at 230V(230V ± 1V) area.
