FS10 Button Setup Quick Guide
This guide provides a quick reference to field set-up of the trip point and span of the FS10A flow monitor on units not pre-calibrated at the factory to
specific application parameters. The available PC or command line interface through the RS232 provides the most comprehensive means of setting
up the FS10A flow monitor (refer to operating manual for complete instructions). If that is not feasible, the buttons with LED feedback provide access
to all required functions for field set-up.
FS10 Button Controls
General Control Description
The FS10 control “functions” can be accessed through the two buttons by:
1. Entering “function selection”
2. Selecting the desired function to adjust
3. Adjusting the function control
4. Exiting to normal operation
1. To Enter “Function Selection” mode:
a. Press and hold both buttons down for 3 seconds
b. When “function selection” is entered, all the LEDs will flash “on”, then
c. The first function (LED # 1) will be illuminated
2. “Function Selection” mode:
Once the unit is in “function selection” mode, the buttons take on new controls:
• The “-“ and “+” buttons will step (increment down or up respectively) through the different functions. The current function number will be
indicated on the LED blinking at the slow rate.
• Holding either the “+” or “-“ for 3 seconds will “select” the current function to be adjusted.
3. When a Function has been selected for adjustment:
After selecting the desired function by pushing and holding either the “-” or “+” button for 3 seconds the LEDs will flash at a faster rate. The
pattern of the LEDs will either reflect the current value of the parameter being adjusted, or the “ready to capture” pattern for parameters to be
captured (see specific function descriptions for details).
The buttons will either increment or decrement the function parameter, or capture a value for the corresponding parameter.
4. To exit out of the current function, push and hold both buttons down for 3 seconds. The LEDs will indicate that you are once again in “function
election” mode, and the current mode will have incremented to the next function. To exit completely (into operational mode), press the two
buttons simultaneously for 3 seconds once again.
Note: Function #4 (load a bank) and function #15 (save to a bank), requires holding either button for 3 seconds to load or save.
Holding both buttons will exit either function without performing the operation.
Button Operation
1 Enter “function selection” Push and hold both buttons simultaneously 3 seconds
2 Select desired “function” Push “+” or “-“ to step through (LEDs indicate function #)
3a. Enter “function adjust” Push and hold either “-“ or “+” button 3 seconds
3b. Adjust within function Follow instructions for particular function entry
4a. Exit “function adjust” Push and hold either “-” or “+” button 3 seconds (now in “function selection” opera-
tion)
[NOTE: Function #4 or #15 requires holding both buttons to exit into function select
operation]
4b. Exit “function selection” Push and hold both buttons simultaneously 3 seconds (now in normal operation)

Bank Selection of Stored Parameters
The FS10A has 7 storage banks. Banks 1-6 are factory set defaults of common applications or specific factory calibrations. Bank 7 is available for
user saved parameters. Bank 0 is always the “operating” bank. Function 4 is used to move parameters from a selected bank to operational Bank 0.
Function 15 is used to store new field set-up parameters into Bank 7 for future retrieval.
Un-calibrated units are shipped with default parameters from Bank 1 active in the 0 Bank. The parameters permit operation over the entire range of
the meter as it may be applied to any gas or liquid.
Recommended Set-up Order
1. Scale the FS10A over the desired flow range — Adjustment of flow over useable range is recommended if possible. This span setting will be
reflected on the LEDs (1-10) as well as the 4-20 mA output (0% - 100%). If it is impossible to throttle the flow, it is recommended a span be
established initially with normal flow, then use the LEDs to set a trip-point below that value for low flow alarm. Dynamic Mode, FUNCTION 5,
automatically establishes the highest flow rate as the span and could be considered to aid in setup in these cases. Refer to Operating Manual
for complete instructions on using Dynamic Mode.
a. Set the Zero using Button FUNCTION 6 (no-flow full tube is suggested in liquid service) to capture the zero point.
b. Set the Span using Button FUNCTION 7. Capture this setting while simulating highest flow rate in the tube.
2. Set the trip point using either method below:
a. 10% increment method, Button FUCNTION 1, allows setting against the 10 LEDs on the display. Each LED represents 10% of the flow
range established in 1. Flashing LED confirms value of trip point.
b. Capture method, Button FUNCTION 2, allows setting the trip-point at precisely the flow rate through the tube at the time of capture.
Flashing LED indicates approximate value of trip point.
3. Final adjustments
a. Set Failsafe using Button FUNCTION 3; relay normally activated above trip point (default condition) or below trip point.
b. Other settings are available through the buttons if required, including hysteresis, time delay and filtering. Refer to the Operating Manual
for complete descriptions. After all adjustments are finalized, the new settings now in operational Bank 0 may be saved to Bank 7, 8 or 9
using Button FUNCTION 15.

Description
Button controls adjust relay trip point in
10% increments.
When entering this function the “ready
to capture” LED pattern will be presented
(0101010101). Pressing either button will
“capture” precisely the current flow value
as the new relay trip point.
Selects whether the relay is “on” (energized) if the flow value is above the relay
trip point, or if the relay is “on” (energized) when the flow value is below the
relay trip point. Pressing the buttons will
toggle between the two options (default
= “on” above trip point -- typical for low
flow alarm).
Select and load a bank of configuration
parameters. If the bank corresponding to
the selected index has not been set, the
“error pattern” (1100110011) will display.
Use “+” or “-” to move to a bank that has
desired parameters populated for loading
into active bank (0). **
