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.

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.
