Field service mode
Field service mode enables technicians to query and command key operating
variables in the MS/TP Microset II. A technician presses a particular button
sequence at the MS/TP Microset II to enter field service mode. In field service
mode a technician uses the left buttons to scroll through data codes and the right
buttons to change the value associated with a code.
The lower left of the LCD shows the two-digit data code and the main area
displays the data value. A pre-defined list of data codes is available (see Table 6
on page 36).
Note Fixed codes appear with a period after them, which enables a technician
to distinguish them quickly from custom codes.
The data range in field service mode is –3276 to 3276. When a data value is less
than -999.9, the decimal point is automatically dropped.
Set BV-68 ON (field service lockout) to deny access to field service mode.
Field service mode ends automatically if there is no button activity for 40
minutes.
