9900-1BC Batch Controller Manual
2551 Technical Notes:
• When the blue jumper
illustrated is placed over
both pins, the 2551-XX-11
(Blind Magmeter)
outputs an open collector
frequency signal.
When the jumper is
removed (or placed over
one pin for storage)
the 2551-XX-11 outputs a
Digital (S
3
L) signal.
2551 & 2552
Technical Notes:
• Either Frequency or
Digital (S
3
L) may be used.
• The frequency output will
be displayed as positive
fl ow regardless of the fl ow
direction.
• Signet recommends
confi guring the 2551
with the Digital (S
3
L)
output because it is more
accurate.
• Input sensor type is
selected by choosing
between “SENSOR FREQ”
and "SENSOR S3L" in the
INPUT menu.
• 5 VDC power is provided to
the 2551 Magmeter by the
9900-1BC. No additional
power is required.
