AO2020描述

電流輸出的出廠設(shè)置為4。。。20毫安。

對(duì)于無(wú)防爆裝置或在2區(qū)/2區(qū)操作的裝置，如下所示

有效時(shí)間：

信號(hào)可以配置為“主動(dòng)”或“被動(dòng)”模式。當(dāng)前設(shè)置包含在

訂單確認(rèn)。

對(duì)于在1區(qū)/1區(qū)操作的設(shè)備，以下內(nèi)容有效：

對(duì)于設(shè)計(jì)用于Ex Zone 1/Div.1的設(shè)備，電流輸出不能重新配置

隨后電流輸出（有源/無(wú)源）所需的配置

在下訂單時(shí)指定。

有關(guān)正確的電流輸出設(shè)計(jì)（有源/無(wú)源），請(qǐng)參閱設(shè)備中的標(biāo)記

接線盒。

如果信號(hào)配置為“激活”模式，則不會(huì)向電流提供外部電源

輸出

如果信號(hào)配置為“無(wú)源”模式，則電流輸出的外部電源為

要求（類似于壓力和溫度變送器）。

對(duì)于帶有PROFIBUS PA的裝置，在啟動(dòng)前檢查或配置總線地址。

如果客戶沒(méi)有提供總線地址信息，則該單元已與其總線一起裝運(yùn)

地址設(shè)置為“126”。

在啟動(dòng)期間，將地址重置為有效范圍（0…125）內(nèi)的數(shù)字。

重要（通知）

所選地址在段中只能出現(xiàn)一次。

地址可以在單元上本地設(shè)置（通過(guò)數(shù)字板上的DIP開(kāi)關(guān)），

使用系統(tǒng)工具，或通過(guò)PROFIBUS DP主類2，如Asset Vision Basic

（日期200）。

DIP開(kāi)關(guān)8的出廠設(shè)置為OFF，即使用現(xiàn)場(chǎng)總線設(shè)置地址。

可以擰下前蓋來(lái)更改設(shè)置。也可以設(shè)置地址

使用顯示板上的鍵通過(guò)菜單。

PROFIBUS PA接口符合Profile 3.01（現(xiàn)場(chǎng)總線標(biāo)準(zhǔn)PROFIBUS，EN

50170，別名DIN 19245[PRO91]）。

變送器傳輸信號(hào)是根據(jù)IEC 61158-2設(shè)計(jì)的。

重要（通知）

制造商特定的PROFIBUS PA ID編號(hào)為：0x3430。

該裝置也可以使用PROFIBUS標(biāo)準(zhǔn)ID 0x9700或0x9740進(jìn)行操作。

The factory setting for the current output is 4 ... 20 mA.

For devices without explosion protection or for operation in Zone 2 / Div. 2 the following

is valid:

The signal can be configured in "active" or "passive" mode. The current setting is contained in

the order confirmation.

For devices for operation in Zone 1 / Div. 1 the following is valid:

For devices designed for use in Ex Zone 1 / Div.1, the current output cannot be reconfigured

subsequently. The configuration required for the current output (active/passive) must be

specified when the order is placed.

For the correct current output design (active/passive), see the marking contained in the device's

terminal box.

If the signal is configured in "active" mode, no external power may be supplied to the current

output.

If the signal is configured in "passive" mode, external power supply to the current output is

required (similar to pressure and temperature transmitters).

For units with PROFIBUS PA, the bus address must be checked or configured prior to start-up.

If no bus address information was supplied by the customer, the unit was shipped with its BUS

address set to “126”.

The address must be reset during start-up to a number within the valid range (0 … 125).

Important (Notice)

The address selected may only appear once in the segment.

The address can be set either locally on the unit (via the DIP switches on the digital board),

using system tools, or via a PROFIBUS DP master class 2 such as Asset Vision Basic

(DAT200).

The factory setting for DIP switch 8 is OFF, i.e., the address is set using the fieldbus.

The front cover can be unscrewed to change the settings. It is also possible to set the address

via menu by using the keys on the display board.

The PROFIBUS PA interface conforms with Profile 3.01 (fieldbus standard PROFIBUS, EN

50170, alias DIN 19245 [PRO91]).

The transmitter transmission signal is designed according to IEC 61158-2.

Important (Notice)

The manufacturer-specific PROFIBUS PA ID no. is: 0x3430.

The unit can also be operated with the PROFIBUS standard ID nos. 0x9700 or 0x9740.
