W.E. Anderson FlotecT V6 Serie Especificaciones - Instrucciones De Instalación Y Operación

The Flowtect ® Model V6 is an inexpensive, explosion-proof flow
switch for use on air, water or other compatible gases and liquids.
Three configurations are available - 1. Factory installed in a tee. 2.
With a trimmable vane for field adjustment and installation in a suit-
able tee. 3. Low flow models with an integral tee and adjustable
valve. All are available with an optional enclosure which is UL and
CSA listed, or Directive 94/9/EC (ATEX) compliant for
EEx d IIC T6 Process Temp 75°C.
INSTALLATION
Unpack and remove any packing material found inside lower
housing or tee.
Switch can be installed in any position but the actuation/deactua-
tion flow rates in the charts are based on horizontal pipe runs and
are nominal values. For more precise settings, units can be facto-
ry calibrated to specific flow rates.
V6 Models with Tee are supplied in 1/2˝ - 2˝ NPT sizes. Install in
piping with arrow pointing in direction of flow.
V6 Low Flow Models have 1/2˝ NPT connections and are field
adjustable. Install in piping with arrow pointing in direction of flow.
To adjust, loosen the four socket head cap screws on bottom.
The adjustment valve rotates 90° between "O" (open) and "C"
(closed). See flow charts for approximate ranges. Tighten screws
once the required flow rate has been set.
V6 with Field Trimmable Vane. These models enable the
installer to choose approximate actuation/deactuation points by
trimming the full size vane at appropriate letter-designated marks
on a removable template. Flows are defined in the following
charts. Note that the charts are based on either brass or cast iron
reducing tees or stainless or forged steel straight tees with bush-
ings where necessary. Install in piping with arrow pointing in direc-
tion of flow.

tion: .1A @ 125 VAC (V~). MT option: 5A @125/250 VAC (V~). [MT option not

Mounting Orientation: Switch can be installed in any position but the ac-
tuation/deactuation flow rates in the charts are based on horizontal pipe
runs and are nominal values.
Set Point Adjustment: Standard V6 models none. Without tee models
vane is trimmable. Low flow models are field adjustable in the range shown.
See set point charts on opposite page.
Weight: 2 to 6 lb (.9 to 2.7 kg) depending on construction.
When bushings are used, they must be back drilled to allow prop-
er clearance for unrestricted vane travel. Bore the I.D. to 13/16˝ (20
mm) on 1/2˝ x 3/4˝ bushings or 1˝ (25 mm) on larger bushings. The
depth of the bore must leave internal threads 9/16˝ (14 mm) high
for proper engagement between the lower housing of the switch
and the bushing. Check for proper vane travel and switch opera-
tion after installation.
ELECTRICAL CONNECTIONS
Connect wire leads in accordance with local electrical codes and
switch action required. N.O. contacts will close and N.C. contacts
will open when flow increases to the actuation point. They will
return to "normal" condition when flow decreases to the deactua-
tion point. Black = Common, Blue = Normally Open and Red =
Normally Closed.
For units supplied with both internal and external grounds, the
ground screw inside the housing must be used to ground the con-
trol. The external ground screw is for supplementary bonding
when allowed or required by local code. Some CSA listed models
are furnished with a separate green ground wire. Such units must
be equipped with a junction box, not supplied but available on
special order.
