Process data output: 2 BYTE (base module --> device (ITV)) The product adjusts the pressure to the set value. BYTE (16Bit) Value Set pressure value. * 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.

When the sensitivity is increased, hunting may occur. When the sensitivity is decreased, hunting will be reduced, but the pressure correction will be reduced, so there may be a moderate pressure instability.

Setting using buttons Caution ① If the incorrect key is pressed or incorrect information is displayed during setting, power must be shut off and the procedure started again. ② It is recommended that the settings are changed without supply pressure. The product operates immediately maximum and minimum pressures are set and the S-key is pressed.
Key locking function Caution The key lock function is preserved in the EEPROM (non-volatile memory). Its settings are reflected even after power cycling. (The key lock is deactivated by default at shipment). This setting interlocks with the key lock for the IO-Link parameter: Device access lock (Index 12) and can also be set via IO-Link.

Gain setting Interlocked with the IO-Link parameter. Normal operation does not require the adjustment of gain. This product can change the response with this gain setting. When the gain is changed to larger, the response become quickly, but there is a possibility that stability is lost.
Sensitivity setting Interlocked with the IO-Link parameter. Normal operation does not require the adjustment of sensitivity. When the sensitivity is changed, the correction operation of pressure changes. When the sensitivity is changed to sharp, the hunting of pressure might be occurred. And, when the sensitivity is changed to dull, there is a possibility that staggering of gradual pressure occur, because the pressure correction become lower.
Zero clear This function is the same as the function via IO-Link. The display can be set to zero again by executing "zero clear". When "zero clear" is executed with residual pressure in the secondary piping, the pressure is assumed to be zero. Please execute the operation of "zero clear" with the supply pressure is intercepted, and the piping of the second side removed.

Initialize This function is the same as the function via IO-Link. "Initialize" is a function to return all the settings that the internal control constant are included to an initial value. Please execute "initialize" only when the error is displayed and this product doesn't operate at all. Please execute the "reset"...
