7.2AXFA11 Operation Using a BT200

This section describes procedures for setting parameters using a BRAIN Terminal (BT200). For more details regarding AXFA11 functions, refer to Chapter 6: Parameter Description; and for more details regarding BT200 operation methods, refer to the BT200 User’s Manual (IM IC0A11-01E).

7.2.1BT200 Connection

Connection to a 4 to 20 mA DC signal line

The communication signal of the AXFA11 is superim- posed onto the 4 to 20mA DC analog signals to be transmitted.

IMPORTANT

Restrictions exist with regard to the distance over which communication is possible. (See Chapter 11: Outline.)

IMPORTANT

If the power of flowmeter is turned off within 30 seconds after parameters have been set, these settings will be canceled. Accordingly, please keep the power on for at least 30 seconds after setting parameters.

IMPORTANT

After approximately 5 minutes of inactivity, the Auto Power-Off function will operate to turn your BT200 off.

7. OPERATION VIA BRAIN TERMINAL (BT200)

IMPORTANT

Be sure to set parameters as “Protect” on the write protect function after the finish of param- eter setting. Refer to the “Menu P: Parameter Protection Items” and section “10.2.2” in detail.

NOTE

In case of BT200, the parameters are displayed in English only.

Even if the language with the exception of English is selected at B10/H30: Language, the param- eters are displayed in English upon BT200.
