Seametrics FT520-86 - 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” (see page 4). 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.
Flow Alarm Connection. Connect the alarm devices to
the appropriate relay terminals. Note that the relays have
both normally-open (NO) and normally-closed (NC) con-
tacts.
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 swith 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
desired to the appropriate terminals. For safety, if using
AC power, be sure to connect the ground terminal
provided to a good earth ground. If using DC power, be
sure to use a Seametrics PC1 (part number 05040) or
comparable 12 V 500 mA power supply.
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.
Settings
Set Units. 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 unit desired. Press for
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 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. Press
for next menu item.
Set Pulse Out. An output pulse is activated at the
selected volume intervals if this feature is in use.
Otherwise, it does not need to be set. Press for
next menu item.
Caution: When the control is
powered up, relay or analog
outputs may be active. If this
could be a hazard, wait to
make external connections
until programming is com-
plete.
