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

Installation
Wall Mounting. Using the four 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 given for
“Panel Cutout”. Be sure to include the four corner screw
holes. After cutting and drilling, place the front plate on
the front side of the panel with its gasket against the
panel, and the remainder of the square housing on the
back side. Slide the screws through the four holes drilled
in the panel, and into the threaded holes in the housing.
Tighten until the gasket is firmly compressed against the
panel.
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 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
used.)
Analog Connection. This output can be configured 4-
20 mA, 0-10 V or 0-5 V by placing a jumper in the cor-
rect position on the analog header. The switch next to
the header selects active (powered) or passive
(unpowered) output. When using the 12 VDC powered
input you may only select passive output.
Power Connection. Connect AC or DC power as

Displays
Replace the front panel, taking care to reconnect the
ribbon cable. When power is switched on, the display
should light up immediately with meaningful letters or
digits.
Settings
Set Flow Rate. Press . 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 units desired. Press to move to the next
menu item.
Set Decimal. Use to select zero, one, or two decimal
places on the flow units. Press to move to the next
menu item.
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
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.

AC power, be sure to connect the ground terminal
provided to a good earth ground. If using 12 VDC, use
a Seametrics PC3 or equivalent 12 VDC 500 mA power
supply.
