The Options Menu contains those features and settings that will normally be set one time and then seldom changed. These include
language preference, decimal placement, Security Code assignment, etc.

Select from English, French, German, Italian, Portuguese or
Spanish. This selection will be displayed at
fi
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.
In
FREQUENCY
output mode, the 2551 serves as a traditional
fl
ow sensor and provides an output pulse that is compatible
with all Signet POWERED
fl
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.
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
