Segment Offset
This function applies ONLY to ProScale Model 150, 250 & 950 systems and
other ProScale products measuring more than 17 inches (430mm) AND
employing Absolute measurement technology.
(If the Aluminum Scale on your product looks
like this it is Absolute technology.)
For measuring systems longer than 17 inches (430mm), multiple measuring
panel segments are installed end-to-end on the Scale (see arrow). This
provides a quasi-absolute measurement capability in which the Encoder can
calculate its position on any individual segment but cannot determine which
particular segment it is currently on. To solve this problem, the Readout tracks
which segment the Encoder is currently on. In certain situations, the crossing
from one segment to another may not be detected. This may occur if the
Encoder is disconnected from the Readout and then moved along the Scale to
another segment. It may also occur if the Encoder is moved too quickly
between segments, (>10ips). If the segment tracking count is incorrect because
of one of these situations, you can re-adjust the Readout to correct the error.
This adjustment is referred to as the
SEGMENT OFFSET ADJUSTMENT
.
To add one segment to the displayed value:
Press and Hold the
UNITS
key and then Momentarily press the + key. The
display will increase by 430.08mm (16.933 inches). To subtract one segment
from the displayed value,
Press and Hold the
UNITS
key and then Momentarily
press the
–
key. This function is operative only when Pr14 is set to 1.
See Programming Parameter (Pr14) for additional information.
Upper/Lower Limits
LCD Readouts can display either LL , for
Lower Limit, or UL , for Upper Limit, if a
user programmed upper or lower reading is exceeded.
Upper and Lower Limits are set with
Programming Parameters Pr28 and Pr29
but
are only active if
Pr27
is set to 1. The display toggles for 2 seconds between the
current measurement and LL if the Lower Limit is exceeded, (or UL if the
Upper Limit is exceeded. This continues as long as either limit is exceeded.
See Programming Parameters (Pr27, 28, 29) for additional information.
For General Purpose and In-Panel Readouts, an output signal may be
configured to activate when either the Upper or Lower limit is exceeded.
