User’s Manual Model EJAA, EJAA and EJAA Differential |

The recommended height between the HP process connection and the transmitter is show in the following table. When a shrouding bolt is driven clockwise by an Allen wrench, it is going in and cover lock is released, and then the cover can be opened.

Therefore, if you switch off the transmitter within two hours from when the error occurs, there is no history of that error stored in the transmitter, and this function is meaningless. UNIT Follow the procedure below jea110a change the static pressure units. This subsection describes the procedures for cleaning and replacing the capsule assembly.

Areas where self-diagnostic offers support 9.

Inhibiting zero adjustment by the 0 P1 F Doing so completes the LRV setting. Either of these terminals may be used.

Setting User-set Engineering Unit c. Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost. Unless otherwise specified by order. Ignore the polarity since the BT is e It is recommended that crimp-on solderless terminal AC-coupled to the lugs for 4 mm screws with insulating sleeves be BT terminal box. Such a manifold makes it easier to disconnect the transmitter from the impulse piping, and is convenient when adjusting the transmitter zero point.


Flexible metal conduit DC power is required for the transmitter loop. An integral indicator can be installed in the following three directions. If the transmitter must be installed in a See Figure 6. Use this function only where there is no alternative. You must do this in order to avoid overloading the transmitter from either the high or the low pressure side when beginning operation.

YES Adjust the output. Then, remove and remount them on the opposite side.

Normally, only non-conductive pollution occurs. Differential pressure transmitters, which serve as the core of field instrumentation, are widely used to jea110a the flow rate, pressure and density of liquids, gases and steam, as well as the level of liquid in a tank. Changing this parameter changes the unit for the A Model pressure regulator pressure pump Pressure range: EPS correction value by adding 4.

Read carefully before using the transmitter. Follow the procedure below to change this setting. Output status at CPU failure and hardware error; Up-scale: EPS terized according to the specification. Indicates that operating the hardware or software in this manner may ea110a it or lead to system failure. Procedure is shown in the figure below.

Sets the calibration range for 4 to 20 mA DC.

Any diagrams, data and other information you can include in your communication will also be helpful.
