* Data is adjustable up to 120%F.S. (Max. guaranteed output pressure accuracy is 100%F.S.)
Pressure setting mode
The pressure can be set by sending input data from the base PLC to the regulator where the
full span is 12-Bit. Do not use values outside of the specification range (including Bit 13th to
15th). They are recognized as large values which could cause an error (Er1).
<Relationship between the set pressure (16-Bit) and output pressure>
Set pressure
Output pressure
Input data shall be entered from Bit 0 to Bit 12 of the 16-Bit process data (2 BYTE).
(When F_1=0%F.S. and F_2=100%F.S.)
(Ex.) When the output pressure is 100%, the set pressure value is 0x0FFF.
