* 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).

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.
