Program Levels 7
A PV around
the lower limit
of the bargraph
programmed range
does not visualize on it.
Programming order
♦Set full access to device parameters.
♦Adjust the parameters.
♦If needed, restrict the access again
by adjusting the Access Control Level parameter.
Access control (Hidden level)
♦Hold depressed while turning
the power supply on and until QxL appears.
♦Set access level according to Table 1.
Basic level
At power-on, TI250 enters Basic level.
At this level, the device shows on the display
the measured input value (PV) with a resolution,
according to the Point Position parameter,
and on the bargraph – the relative position of PV
within the programmed range of the bargraph.
♦If the whole part of PV cannot be entirely
displayed, the unit generates blinking
'overflow' messages (oL or -oL, depending
on PV sign). If PV is out of the bargraph
programmed range, the corresponding
endmost LED of the bargraph blinks.
♦If PV is out of the device physical operating
range, blinking symbolic messages –
<_> (under-range) or {+} (over-range) –
appear on the display, and the respective
endmost LED of the bargraph blinks.
♦Upon entering Basic level, BBI250 may display
the ini message, indicating that some time
is necessary for filter initialization.
In such case, the bargraph goes off.
♦The noi message may appear as a result
of the peak filter operation (see 'Input filtration').
In such case, the bargraph goes off.
Set-point adjustment (Level L1)
♦To enter Set Point 1 adjustment mode, press
and hold until %[1 appears on the display.
Release the key to view the set-point value.
♦To enter Set Point 2 adjustment mode, follow
the same procedure, but start with the key.
