W.E. Anderson Flotect V6 Serie Instrucciones De Instalacion Y Uso

The Series V6 FLOTECT Flow Switch is an inexpensive, explosion-proof flow
®
switch for use on air, water or other compatible gases and liquids. Three configura-
tions are available - 1. Factory installed in a tee. 2. With a trimmable vane for field
adjustment and installation in a suitable 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 2014/34/EU (ATEX) compliant for
II 2 G Ex db IIC T6 Gb
Process Temp≤75°C or IECEx compliant for Ex db IIC T6 Gb 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/deactuation flow rates in
the charts are based on horizontal pipe runs and are nominal values. For more pre-
cise settings, units can be factory 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 ap-
proximate 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 bushings where necessary. Install in piping
with arrow pointing in direction of flow.
When bushings are used, they must be back drilled to allow proper 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 operation after installa-
tion.

ELECTRICAL CONNECTIONS
Connect wire leads in accordance with local electrical codes and switch action re-
quired. 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 deactuation point. Black = Common, Blue = Normally Open and Red = Normally
Closed.
For units supplied with both internal ground and external bonding terminals, the
ground screw inside the housing must be used to ground the control. The external
bonding screw is for supplementary bonding when allowed or required by local code.
When external bonding conductor is required, conductor must be wrapped a mini-
mum of 180° about the external bonding screw. See below. 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.
