Seametrics FT520-84 v.1 - Manual (Page 2)

Installation
Wall Mounting. Using the eight screws provided, attach
the two foot brackets to the sides of the enclosure. Then
attach the unit to any secure surface by inserting screws
through the mounting holes in the foot brackets.
Panel Mounting. Follow the dimensions for “Panel
Cutout” to cut a hole in the panel. Slide the panel mount
gasket up from the bottom of the enclosure to its place
behind the panel mount flange. Insert the unit through
the panel cutout. Install the two panel mount brackets
on the sides of the unit using the eight screws provided.
Each bracket has one threaded center hole. Insert and
tighten one screw in each hole, until the flange is pulled
firmly up against the panel and the gasket is compressed.
Expose Terminals. Remove the four screws which hold
the front plate to its flange. Remove the front plate. The
display board is attached to this front plate. It is also
connected to the power board by a ribbon cable. For
convenience, this cable can be disconnected, or the
display board can be allowed to dangle while making
connections. Connections can be made inside the
enclosure, or the terminals can be unplugged for easier
access, by gently tugging on them.
Sensor Connection. Follow the “Connections” diagram
to connect either two or three wires from the flow meter
or flow sensor.
Regeneration Valve Connection. Connect the leads
which initiate the regeneration valve(s) to the terminals
marked Relay 1 and Relay 2. (See “Connections” dia-
gram.) If only one unit is being connected, use Relay 1.
(Relay 2 will operate only if “Alternate Relays” mode is
being used.)
Power Connection. Connect AC or DC power as
desired to the appropriate terminals. For safety, if using
AC power, be sure to connect the ground terminal
provided to a good earth ground.

Settings
Set Flow Rate. Use to select volume units. Use
to select the particular unit desired (gallons, liters, etc.).
Then use
to switch to time units. Again, select the
one desired.
Set Decimal. Use to select zero, one, or two decimal
places on the flow units.
Set K-Factor. The unit will not function properly until
this number is entered. It is simply the number of pulses
which the flow meter or flow sensor puts out per gallon
of liquid. It is marked on the Model/Serial tag of
SeaMetrics flow meters and flow sensor fittings. On
adjustable flow sensors, the K-factor must be taken from
the chart in the flow sensor instructions, based on pipe
size. Set the number with
keys. The digit which
is underlined is the one being set. The moves one
digit to the left. The increases the digit. When the
appropriate number has been set, press again to
move on to the next menu item.
Caution: When the control is
powered up, relay or analog out-
puts may be present. If this
could be a hazard, wait to make
external connections until pro-
gramming is complete.
!
Replace the front panel, taking care to reconnect the
ribbon cable if it has been disconnected. When power
is switched on, the display should light up immediately
with meaningful letters or digits.
