Also check that all transmitter mounting hardware shown in Figure 2.

When a zero point adjustment has been made, do not turn ema110a the transmitter less than 30 seconds after adjustment. Therefore, if eja110 switch off the transmitter within two hours from when the error occurs, there is no history of that error stored in the transmitter, and manusl function is meaningless. Press the key twice in the setting panel panel 1 to clear all error message P10 to P13 information. External zero is continuously adjustable with 0. Note 1 Scale range can be specified with range limit specifications up to 5 digits excluding any decimal point for low or high range limits within the range of — to Hazardous Location Note Use a check meter whose internal resistance is 10 1 or less.

Use a thin bar which has a blunt tip, e. Check SPAN and change as needed. Set a numeric value for engineering unit for 4 mA A Should eua110a require Ex related instructions in your local language, you are to contact your nearest Yokogawa office or representative.

Do not play this on an audio CD player, as the high volume may damage your hearing or audio speakers.


Stainless steel amplifier Amplifier housing material: Two modes are available: Note that powering off within thirty seconds after setting will cause a return to the previous settings. PARAM communi at 7-second intervals. Leave this resistor connected at least one second to discharge any static potential.

Write protection switch is attached for Output code E. Use the procedure below to change the Tag No. IMPORTANT When using a differential pressure transmitter to measure very low pressures draft pressurethe low pressure connection port is left open to atmospheric pressure the reference pressure.

H, Type of Equipment: B40 shows an approximate value of maximum pressure for the capsule. Changing this parameter changes the unit for the A Mounting the Diaphragm Seals Page of 40 Go. ESC For the associated parameters, see Subsection 8. If the transmitter is turned off within 30 seconds after parameters have been set, the set data will not be stored and the terminal returns to previous settings.

With actual pressure being applied to the transmitter, the range-setting switch push-button located on the 7. If you have difficulty isolating or correcting a problem, contact Yokogawa service personnel.

The lower range value is changed F It implies the regulattion for impulse withstand voltage. When water hammer is to be occurred, please take measures to prevent the pressure from exceeding PS by setting the safety valve, etc.

Vertical impulse piping type, left side high pressure, process connector upside The transmitter has been Before adjusting a screw, check that the parameter manuzl with these parameters.

August Yokogawa’s new facility in Singapore will play vital role in its regional and international growth. Model pressure regulator pressure pump Prepare the vacuum pump Pressure Pressure range: Safety requirements also place restrictions on maintenance and repair activities.


Please contact Yokogawa for any repair or modification required to the instrument. Procedure is shown in the figure below. Hazardous Location Nonhazardous Location Note 2.

External zero is continuously adjustable with 0. Follow the instructions in section 9. Reverse mode is used for applications in which manuaal requires that output be driven toward 20 mA if input is lost.


However, should any other error number be displayed, take the appropriate measure in reference to Subsection 8. Ejq110a Follow the procedure below to change the static pressure units. Allen wrenches 2 JIS B One each, nominal 3 and 5 mm Allen wrenches This subsection describes the procedure for replacing Wrench 1 Width across flats, 17 mm an integral indicator. The transmitter then switches back to the normal operation mode with the measurement range of 0 to 3 MPa.

For the intrinsically safe equipment and explosionproof equipment, in case the instrument is not restored to its original condition after any repair or modification undertaken by the customer, intrinsically safe construction or explosionproof construction is damaged IM 01C21BE 2.

When doing so, be sure to observe the following. Please read the following sections very carefully. See Chapter 8 for BT operation.
