2.2 Setting PV Input Type
(Setting First at Power-on)
NOTE
• The controller displays an operating display when the power is turned on. The
submenu “IN” appears at this point if the type of PV input has not been defined yet. In
this case, first press the
SET/ENT
key once to display the parameter “IN1” for the PV input
type. Then, set the maximum value (RH1) and minimum value (RL1) of the PV input
range (for voltage input, set the maximum value (SH1) and minimum value (SL1) of
the PV input scale). Press the
SET/ENT
key to register the settings. See the operating
procedure below for more details.
• The controller is configured to the default of each parameter at the factory before
shipment.
First check these defaults listed in “6.2 Lists of Parameters,” and change their values
if necessary.

Parameters to be set for temperature input
1. PV input type (IN1): Set according to a sensor
2. Maximum value of PV input range (RH1): Set the
maximum value of the range to be controlled.
3. Minimum value of PV input range (RL1): Set the
minimum value of the range to be controlled.
Parameters to be set for voltage input
1. PV input type (IN1): Set according to an input signal
2. Maximum value of PV input range (RH1): Set the maximum value of an input signal.
3. Minimum value of PV input range (RL1): Set the minimum value of an input signal.
4. Position of PV input decimal point (SDP1): Set the position of the decimal point for PV input display.
5. Maximum value of PV input scale (SH1): Set the maximum value of the scale to be controlled.
(Set a reading for the maximum value of the input signal.)
6. Minimum value of PV input scale (SL1): Set the minimum value of the scale to be controlled.
(Set a reading for the minimum value of the input signal.)
