2.2 Setting PV Input Type (Setting First at Power-on)
NOTE
• The controller displays the operating display when the power is turned on. However, if
PV input type has not been set, “IN” appears. In this case, first use the
key to
display the input range code to use, then press the
SET/ENT
key to register it. Then, set
the maximum value (RH) and minimum value (RL) of the PV input range (for voltage
input, set the maximum value (SH) and minimum value (SL) of the PV input scale).
• The controller is configured to the initial value of each parameter at the factory before
shipment.
First check the initial values shown in “5.2 Lists of Parameters,” and change param-
eter values as necessary.

Parameters to be set for temperature input
1. PV input type (IN): Set according to a sensor
2. Maximum value of PV input range (RH): Set the
maximum value of the range to be controlled.
3. Minimum value of PV input range (RL): Set the
minimum value of the range to be controlled.
Parameters to be set for voltage input
1. PV input type (IN): Set according to an input signal
2. Maximum value of PV input range (RH): Set the maximum value of an input signal.
3. Minimum value of PV input range (RL): Set the minimum value of an input signal.
4. Position of PV input decimal point (SDP): Set the position of the decimal point for PV input display.
5. Maximum value of PV input scale (SH): Set the maximum value of the scale to be controlled.
6. Minimum value of PV input scale (SL): Set the minimum value of the scale to be controlled.
