Insert the pin CN4 as shown in the figure above to set the burn-out direction.

If the transmitter is equipped with an integral indicator, refer to Subsection 9. ESC key twice to F Adjust the zero point.

Maintenance of the transmitter is easy due to its modular construction. When doing this, lightly press the side of the CPU assembly connector and pull the cable connector to disengage. NOTE Whenever shutting down the transmitter for a long period, remove any process fluid from the transmitter pressure-detector section.

Switching language of messages Japanese or English 4.

Use for specific purposes. An Allen head bolts shrouding bolts are provided under edge of the each cover for locking. Zero point can be adjusted by simple key operation of the BT Union or flange Self-diagnostic error on the integral indicator Faulty transmitter Vent plug Fill plug Tap valve F Check Meter Connection Intrinsically Safe Type Wetted parts material S.


The transmitter is designed to withstand severe environmental conditions. The zero point adjustment can be made with a resolution of 0. When the instrument is shipped, the damping time constant is set at 2. In case of a failure, manjal is disabled.

However, other changes in the display settings scale range and engineering unit for the integral indicator requires BT If a pressure generator is used: Doing so completes the LRV setting. Select the method best suited for the conditions of your application. Entering Digits, Symbols, and Spaces 0 to 9.

manusl Check LRV and modify as needed. If the lower and higher range values are set, C In this instrument, changing the low range value also automatically changes the high range value, keeping the span constant. Yokogawa’s DPharp high static pressure transmitter offer long-term stability and diagnostics to make your maintenance routine easy.

When combining with Optional code F1, output status for down-scale is —2. When a zero point adjustment has been made, do not turn off the transmitter less than 30 seconds after adjustment. To prevent such problems, the process pressure taps must be angled as shown in Figure 5.

Conditions Of Communication Line Zero can be fully elevated or suppressed, within the Lower and Upper Range Limits of the capsule. This error code appears at a capsule problem or when an illegal overpressure is applied to the pressure sensor.


Calibration Range Setup OK The low range value is not changed, so the span changes. The installation must be in accordance with the description about the type of protection in this instruction manual.

Save an inspection date of January 30, Wait until the pressure inside the manula section has stabilized before proceeding to the next step.

Ground terminals are located on the inside and outside of the terminal box. Grounding is always required for the proper operation of transmitters. Zero Point Adjustment manaul DC power is required for the transmitter loop.

Reverses the manuak for 4 to 20 mA DC output relative to input. Select instruments that will enable the transmitter to be calibrated or adjusted to the required accuracy. Since the degree of zero adjustments varies with the screw turning speed, turn the screw slowly for fine adjustment and quickly for coarse adjustment.
