GF Signet 2551 Magmeter Flow Sensor - Blind - Manual (Page 6)

6 2551 Magmeter
• When the blue jumper illustrated here is placed over both pins, the
2551-XX-11 outputs an open collector frequency signal that can be
connected to any powered Signet À ow meter (models 5600, 8900,
9900).
• 5 VDC power is provided to the 2551 Magmeter by all Signet À ow
instruments. No additional power is required.
• The frequency output will be displayed as positive À ow
regardless of the À ow direction.
• When the blue jumper illustrated here is removed (or placed over
one pin for storage) the 2551-XX-11 outputs a Digital (S 3 L) signal
compatible with the Signet 8900 and 9900.
• The 2551 receives 5 VDC power from the 8900 or 9900. No
additional power is required.
• The 8900 will display 0 (Zero) À ow rate during periods of
reverse À ow. The 9900 will display negative numbers to
indicate reverse À ow.
• The maximum cable length from the 2551 to the 8900 or 9900
depends on the 8900 or 9900 con¿ guration. Refer to the 8900 or
9900 manual for complete information.

9. Calibration and Software Con¿ guration
No calibration is necessary to begin using the 2551. The application and performance settings are pre-set to meet the requirements of
most applications.
The 2551 application and performance settings can be customized using the Signet 3-0250 USB to Digital (S 3 L) Con¿ guration/
Diagnostic Tool and software. Refer to the Signet 3-0250 USB-to-S 3 L Con¿ guration/Diagnostic Tool manual for details to adjust the
following parameters:
• 4 to 20 mA span: Factory setting is 0 to 5 m/s. Can be customized to any range.
• Noise Rejection Filter: Factory set for 60 Hz. Can be changed to 50 Hz.
• Low Flow Cutoff: Factory setting is 0.05 m/s. Can be customized to any velocity.
• Averaging Time: Factory setting is 14 seconds. Can be customized from 0.1 seconds to 100 seconds.
• Sensitivity: Factory setting is 25% of full scale. Can be customized to any % of full scale.
If connecting the 2551 Magmeter to a À ow instrument from
another manufacturer, 5 to 24 VDC power must be provided to
the 2551. A 10 KŸ pull-up resistor (not supplied) must also be
connected between terminals 1 and 2.
