You can manually perform the trimming procedure by using J This section describes procedures for setting parameters mnaual the BT The calibration instruments should be handled carefully so as to maintain the specified accuracy.

Impulse Piping Connection Examples Checking With Integral Indicator Wait until the pressure inside the pressure-detector section ema530a stabilized before proceeding to the next step. It implies the regulattion for impulse withstand voltage. Abnormalities appear in measurement.

When the instrument is shipped, this is set as specified in the order. Ground terminals are located on the inside and outside of the terminal box.

A display when parameter SET J Before online-communication, confirm that communication signal does not give effect on the upper system. To confirm or change the values, see Subsection 8.

The parameter is set to HIGH. With present settings of 0 to 30 kPa, set the Higher range value to10 kPa.

Shutting Down Operation Hysteresis of cut point: Zero adjustment is completed. The user is permitted, however, to replace a capsule assembly with another of the same measurement range.


Reverses the direction for 4 to 20 mA DC output relative to input. Add Optional code C2 and C3. Safety requirements also place restrictions on maintenance and repair activities.

Sets the status of the 4 to 20 mA DC output when an abnormal status is detected with the capsule or the amplifier as the result of self-diagnosis. Change wating period manuak opening terminal cover after power off from 1 min. Press the CLR A Refer to Section 6. When combining with Optional code F1, output status for down-scale is —2. To prevent communication signal affecting the upper system, it is recommended to install a lowpass filter manaul 0.

The display is always 0 MPa, but this is not manuql measured value. Check SPAN and change as needed. Set the correction value, 1. Set the lower limit with D Outputs the signal Hold, High, or Low set with parameter D However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping.

For the installation of this transmitter, once a particular type of protection is selected, any other type manuwl protection cannot be used.

EJA530A In-Line Mount Gauge Pressure Transmitter (DISCONTINUED)

If there is more than one error, ejja530a error number changes at two-second intervals. Leave this resistor connected at least one second to discharge any static potential. Tools for Disassembly and Reassembly Tool Phillips screwdriver Slotted screwdriver Ejq530a wrenches Wrench Torque wrench Adjustable wrench Socket wrench Socket driver Tweezers Integral indicator can be installed in the following three directions.


Alphanumeric Keys And Shift Keys The transmitter is designed to eja530w severe environmental conditions. Parameters C21 and C22 are changed at the same time. For general-use and Flameproof type. Selecting The Wiring Materials Does the self-diagnostic indicate problem location? Mounting The Diaphragm Seals Even if the BT power supply is turned off or the communication cable is disconnected during test output, it is held for approximately 10 minutes.

This feature provides 5 user memo fields, each holding up to 8 alphanumeric characters.

Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost. Test Output Setup NO Are valves opened or closed correctly? Conditions Of Communication Line When the higher range value is to be changed to 10 kPa with the present setting of 0 to 30 kPa, take the following action with an input pressure of 10 kPa applied. The measured data is updated automatically every 7 seconds. Unit setup for displayed temperature P.
