Installation Precautions
4 Read these instructions before using the gauge. Configuration may
be easier before installation. Contact the factory for assistance.
4 These products do not contain user-serviceable parts. Contact us
for repairs, service, or refurbishment.
4 Gauges must be operated within specified ambient temperature ranges.
4 Outdoor or wash down applications require a NEMA 4X gauge or
installation in a NEMA 4X housing.
4 Use a pressure or vacuum range appropriate for the application.
4 Use fittings appropriate for the pressure range of the gauge.
4 Due to the hardness of 316 stainless steel, it is recommended that
a thread sealant be used to ensure leak-free operation.
4 For contaminated media use an appropriate screen or filter to
keep debris out of gauge port.
4 Remove system pressures before removing or installing gauge.
4 Install or remove gauge using a wrench on the hex fitting only. Do
not attempt to turn gauge by forcing the housing.
4 Good design practice dictates that positive displacement liquid
pumps include protection devices to prevent sensor damage from
pressure spikes, acceleration head, and vacuum extremes.
p Avoid permanent sensor damage! Do not apply vacuum to non-
vacuum gauges or hydraulic vacuum to any gauges.
p Avoid permanent sensor damage! NEVER insert objects into
gauge port or blow out with compressed air.
Gauges are not for oxygen service. Accidental rupture of sensor
diaphragm may cause silicone oil inside sensor to react with
oxygen.
p NEVER connect the gauge wires directly to 115 VAC or perma-
nent damage will result.

Electrical Connection
All operating power is supplied by the 4-20 mA current loop using
the 2-wire cable at the gauge rear. The F16LSC can be used as
an indicating transmitter in any 4-20 mA current loop or as a DC
powered gauge. Reversing the connections will not harm the gauge
but it will not operate with incorrect polarity.
Select a loop power supply voltage and total loop resistance so that
when the loop current is 20 mA, the gauge will have at least 10 VDC
at its terminals but not over 32 VDC.
For correct operation and to avoid erratic or erroneous readings, the
gauge terminal voltage must not fall below 10 VDC. Too large a loop
resistance will cause the gauge output to "limit" or saturate before
reaching its full 20 mA output. The minimum loop supply voltage
may be calculated from the formula:
V
= 10V + (20mA x Total loop resistance)

To use the transmitter as a low
voltage powered gauge connect it
to any 10-32 VDC power supply.

Normal Operation
The F16LSC is designed for continuous operation. Warm-up time
is negligible.
When loop power is applied, the gauge will power-up automati-
cally. All active display segments are turned on for approximately
1 second.
After initialization, the gauge will begin operating in the Normal
Mode. The display will show the applied pressure. The loop cur-
rent and the Loop-Tracker
LED brightness will correspond to the
®
applied pressure.
The output is a 12,000 count analog 4-20 mA signal. The output
is filtered to improve noise immunity and is updated approximately
16 times per second.
Zero Tare, Push-To-Test, Configuration and Calibration modes are
accessible from the Normal Mode.
The power supply for the Backup Power mode recharges during
Normal Mode operation.
It takes approximately two hours of operation in the Normal Mode to
fully charge the backup power supply from the loop supply.
If loop power is lost, the gauge will automatically switch to the
Backup Power mode and continue to display the applied pressure
for 15 seconds.
Below are the 4-20 mA output values for various types of sensors,
assuming the output scale has not been adjusted.
