For Switching Angle Up to 180° (D, S
–
4 option ca
n rotate up to
180° if only two targets are utilized):
Step 1
: Remove shaft from Switchbox by removing the circlip underneath
the Switchbox.
Step 2: Remove the open switch from the bracket and install it on the inside
of the bracket.
Step 3: Remove the open striker assembly (green) by removing the circlip
or screw on top and install it on the inner rack next to the red
striker assembly.
Step 4: Re-install the shaft in the Switchbox and fit the s/s washer and
circlip to the underside of the Switchbox.
Step 5: The open switch can now be set anywhere between
90° & 180°.
Setting Slotted Inductive Sensors:
Step 1: Loosen set screw
Step 2: Rotate cam(s) and collar(s) until desired switch
function is achieved
Step 3: Tighten set screw
Pneumatic Hookup Procedures:
Prior to connecting the supply air to the spool valve,
flush the system to remove any debris or contaminates.
Galvanized pipe can easily flake and contaminate the
system and therefore is not recommended. A 40 micron
point of use filter at every device is recommended.
4-Way Spool Valves
The TopWorx™ spool valve is a 5
-port, 4-way valve driven by an internally
mounted pilot valve. The spool valve supply port and work ports are marked as
follows:
Highly Recommended
TopWorx™ highly recommends Locktite 567 brand thread sealant. Do not use
a
hard setting pipe compound. If Teflon thread seal tape is used, start the wrap
on the second thread from the leading thread of the fitting. This will
prevent tape shreds from contaminating the spool valve seals.
Breathers (AL-M30 1/
8” NPT
) should be installed in the exhaust
ports to keep debris from falling into the spool valve and damaging the seals.
This must be addressed prior to installation, or storage.
A flow control may be used in Port 3 but should NEVER BE USED in Port 5.
Any blockage or restriction may cause an internal pressure build-up inside
the enclosure and pose a safety issue.
and the external ground connection, if supplied in addition, is supplemental
bonding allowed where local authorities permit, or is required. Refer to the TX-
Series Master IOM for Proof Testing instructions. Switchbox cover screws are
not of standard form and they may only be replaced with identical screws
sourced from the manufacturer (minimum grade A2-70 or A4-80 to ISO 35061).
Switchbox cover screws should be tightened to a minimum of 10.85 Nm (8 ft-lb).
When installing with a third party listed nipple-mount solenoid, it is the
responsibility of the installer to provide fittings, and apparatus, suitable for the
area classification in accordance with the National Electrical Code. All cable
entry devices or conduit stopping boxes shall be certified in type of explosion
protection, suitable for the conditions of use, and correctly installed.
The IIC enclosures are excluded from use in Carbon disulphide atmospheres.
The air pressure to the valve block, when fitted, shall not exceed 7 bar.
Preventative Maintenance
TopWorx™ Switchboxes are designed to operate for one million cycles without
servicing. Call TopWorx™ when you are approaching this milestone for a
preventative maintenance kit and instructions.
