Select from English, French, German, Italian, Portuguese or
Spanish. This selection will be displayed at ¿ rst power-up of a new
magmeter.
Security Code can be set to any four digit number. Factory standard
setting is 0000.
Set for best view after the magmeter is installed. Larger number
means display appears darker.
Lock ON requires the Security Code before resetting the
Resetable Totalizer. Lock OFF reset with no security code.
Filters out common 50 or 60 Hz electrical noise.
Set the maximum resolution for the FLOW RATE display by
limiting the decimal to this point. The Flow Rate display will auto-
scale from this resolution up to whole units.
Set the maximum resolution for the TOTALIZER display by
limiting the decimal to this point. The Totalizer display will always
show this resolution.
Select decimal point or comma for use in numeric displays.
For Frequency/Digital models only: Select Freq output, Freq ÷ 10
output, Mirror Relay 1 output or S
3
L Digital output.
11.1 Output Modes
In FREQUENCY output mode, the 2551 serves as a traditional À ow sensor and provides an output pulse that is compatible with all
Signet POWERED À ow instruments. It is not compatible with the 5090 Self-Powered Flow Meter or the 8150-1 Battery-Powered Flow
Totalizer. The frequency output range is from 0 Hz to 1000 Hz.
The FREQUENCY ÷ 10 output mode reduces the output frequency of the 2551 to a range that is useful for some programmable
logic controllers (PLC). The frequency output range is from 0 Hz to 100 Hz. This shift does not affect the stated accuracy of the 2551
Magmeter's frequency output.
The MIRROR RELAY 1 output mode allows 2551 Frequency/Digital models to use the Open Collector Output like a relay that can be
programmed via the Relay 1 menu.
If the magmeter is equipped with relays, this mode will mirror the settings of Relay 1.
If the magmeter is not equipped with relays, this mode can still be selected and programmed via the Relay 1 menu.
The S
3
L Digital output mode switches the 2551 to the Signet serial data output called S
3
L (Signet Serial Sensor Link). In this mode the
2551 can be added to the serial bus of the Signet 8900 Multi-Parameter Controller or 9900 Transmitter.
Shown for 4 to 20 mA models only (3-2551-XX-22, -42).
Use the keypad to enter any current output from 4.0 mA minimum
to 22.1 mA maximum.
10. Test Menu
The Test menu provides a simple method to verify that the system is operating properly. Auxiliary power MUST be connected to the
2551 to activate the relays
