4.1 Checking for Problems

4.1.1 Identifying Problems with BT200

The following four areas can be checked.

(a) Whether connections are good.

(b) Whether BT200 was properly operated.

(d) History of the errors.

See examples below.

• Example 1: Connection errors

ESC

communication error

Press the key.

When the panel shown on the

left appears, press the

key.

Since communications will be

unsuccessful if there is a problem

in the connection to the BT200,

the display at the left will appear.

Recheck the connection.

Press the (OK) key.

• Example 3: Checking the history of the errors

Connect the BT200 to the

transmitter, and call item “P.”

The history of up to four errors can be stored. When the

5th error has occurred, it is stored in “P10.” The error

stored in “P16” will be deleted, and then, the error in “P14”

will be copied to “P16.” In this sequence, the history of the

most previously occurred error will be removed from

memory.

“GOOD” will be displayed if there was no previous error.

<(a) SETUP PANEL>

P10: “ERROR REC 1” displays the last error.

P12: “ERROR REC 2” displays the error one time before

the last error occurred.

P14: “ERROR REC 3” displays the error two times before

the last error occurred.

P16: “ERROR REC 4” displays the error three times

before the last error occurred.

Select P10: ERROR REC1 and

press the key to

display the error message.

Note 1: Press the key twice in the setup panel

(a) to clear all error message (P10 to P16)

information.

Note 2: When the error occurs, the self-diagnostic detects

errors and records them in two ways depending on

the types of errors. The amplifier/capsule failures

are recorded immediately after the occurrence,

while the minor errors such as warnings of

inappropriate parameter settings are periodically

recorded at an interval of minimum five minutes to

twenty four hours.

Note that the interval extends as the number of

access counts to EEPROM increases.
