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 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, 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.

Monitor Alarm Connection. Connect the alarm devices
to the appropriate relay terminals. Note that the relays
have both normally-open (NO) and normally-closed (NC)
contacts.

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.

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. Use

to select volume units. Use

select the particular unit desired (gallons, liters, etc.).

Then use

to switch to time units. Again, select the

one desired.

Set Time Period. This is the monitoring period at the
end of which the unit will alarm if total flow has exceeded
its setting. To set this monitoring period in hours, use the

and

keys. The digit which is underlined is the one

being set. Use the

to increase it. The

moves one

digit to the left. Note that if the digit to the right is set to
“9”, the digit to the left will only go to “3”. This is because
48 is the maximum setting allowed.

Set Alarm Point. This is the maximum total flow al-
lowed in the time period set above. Use the same proce-
dure as above to set this value, up to nine digits. The
units are as shown (previously chosen).

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

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.
