7.2 Display range and set range of current detector input
7.2.1 Display range and set range: 0.0 to 50.0A AC
7.3 Voltage input
7.3.1 Voltage input: Entering a voltage (12 to 24V DC) from outside enables the selection of
functions from "7.3.2. Voltage input functions."
7.3.2 Voltage input functions
Function type When voltage is applied
None
SV/SV2 function SV2
RUN/READY function READY
Auto/manual function Manual
Forward/reverse operation function Forward operation
Auto-tuning function AT start
Forward operation (SV2)/reverse operation (SV) function Forward operation (SV2)
7.4 Control output
Control output is ensured by open collector output. Control operations can be selected from
heating control or heating/cooling control (types A and B). Setting the output 2 control type to
"ON/OFF control" or "PID control" activates heating/cooling control.
Note that heating/cooling control is fixed at control output on the side of heating output, and at
temperature alarm output on the side of cooling output. See the table below for the allocation of
control outputs and temperature alarm outputs for heating control and heating/cooling control.
