Frequency output (Compatible with all POWERED Signet Flow instruments.) Blue Jumper ON = FREQ OUT <br />• When the blue jumper illustrated here is placed over both pins, the 2551 -XX -11 <br />outputs an open collector frequency signal that can be connected to any Frequency <br />powered Signet flow meter (models 8900, 9900, 9900-1 BC). •e =- —_= <br />• 5 VDC power is provided to the 2551 Magmeter by all Signet flow instruments. <br />No additional power is required. <br />• The frequency output will be displayed as positive flow regardless of the a f S <br />flow direction. <br />2551 Wiring to Signet 8900 <br />2551 Wiring to <br />4W4:;' Notmed <br />Signet 9900 and 9900-1 SC <br />9900 Transmitter <br />Freq. <br />Fr=====s <br />t- --) <br />Ground <br />< D Z to <br />UO Module 3-8900.401-X <br />- - - <br />Date <br />+ D p <br />• <br />Freq.

No acditional power is required <br />• The 8900 will display 0 (Zero) flow rate curing periods of reverse flow. <br />The 9900 will display negative numbers to indicate reverse flow. <br />• The maximum cable length from the 2551 to the 8900 or 9900 depends on the 8900 or <br />9900 configuration. Refer to the 8900 or 9900 manual for complete information. <br />2551 Frequency Out to other manufacturer's equipment <br />• If connecting the 2551 Magmeter to a flow instrument from another <br />manufacturer, 5 to 24 VDC power must be provided to the 2551. <br />• A 10 KSS pull-up resistor (not supplied) must also be connected <br />between terminals 1 and 2. <br />�x:l r r►eisi �� im4�7 - , <br />2551 <br />Blue Jumper OFF = S3 OUT <br />Not used <br />S3L <br />bio <br />LJ <br />• <br />Frequency Out <br />C __ <br />Yo `�'<-- 5-24 VDC <br />Install a pull-up resistor when connecting the <br />2551 Magmeter to other manufacturer's flowmeters. <br />No calibration is necessary to begin using the 2551. The application and performance settings are pre-set to meet the requirements <br />of most applications. <br />The 2551 application and performance settings can be customized using the Signet 3-0250 USB to Digital (SIL) Configuration/ <br />Diagnostic Tool and software. Refer to the Signet 3-0250 USB to Digital (SIL) Configuration/Diagnostic Tool manual for details to <br />adjust the following parameters: <br />• 4 to 20 mA span: Factory setting is 0 to 5 m/s. Can be customized to any range. <br />• Noise Rejection Filter: Factory set for 60 Hz. Can be changed to 50 Hz. <br />• Low Flow Cutoff: Factory setting is 0.05 m/s. Can be customized to any velocity. <br />• Averaging Time: Factory setting is 14 seconds- Can be customized from 0.1 seconds to 100 seconds. <br />• Sensitivity: Factory setting is 25% of full scale. Can be customized to any % of full scale. <br />+GF+ 2551 Blind Magmeter 7 <br />
