Proximity Switches
DESCRIPTION
Graco’s Trabon Cycle Proximity Switches are used for providing a
signal to a Monitor, Controller or Programmable Logic Controller
(PLC) to indicate the number of cycles and cycle rate of a
Series-Progressive (SP) divider valve; this signal is transmitted
via a feedback loop to the Controller, providing the status of the
lubrication cycle it is programmed to monitor and record.
Graco offers three types of proximity switches for use on SeriesProgressive divider valves: Reed-Type (Reed) Proximity Switch,
Field Sensing Magnetic (FSM) Proximity Switch, and Field Sensing
Mechanical (FSmech) Proximity Switch. All are magnetically
operated, single-throw switches that sense the movement of the
divider valve’s piston when it is cycling.
The Reed-Type proximity switch is available as an unattached
version (magnetically attached to piston) for oil-only applications
using MSP, MH or MGO divider valve assemblies.
The Field-Sensitive Magnetic proximity switch is a dry
contact, ceramic magnet operated switch. It can be used in
either grease or oil applications and is available in three sizes
compatible with MSP, MH, MX/MXP, and MGO assemblies and
its use is not limited by valve section size. This switch is also
available in an explosion-proof design with a six-foot long
cable for use in MS/MH divider valves.
The FSmech proximity switch is designed to provide a greater
reliability of operation when used with the very low signal power
conditions common to DC-powered PLC’s. It is a magnetically
activated proximity switch that contains a miniature snap-action
switch, activated by the attraction of its internal magnet to the
divider valve’s moving piston. The 24 volt DC-only version of this
switch is available with integral light-emitting diodes (LED) for
local verification of power and cycling activity. Similar designs
without LED’s are suitable for either AC or DC power operation;
there is also an explosion-proof version with six foot long pigtail
leads. FSmech proximity switches are available for MSP, MH, and
MX/MXP divider valve assemblies.
Each type of Graco Proximity Switch is available with a variety
of customer-required options to fulfill each of their application’s
particular specifications: 24 VDC or 115 VAC power, LED cycle
indicator lights for DC applications, and various types of electrical
connection options: Brad Harrison or Crouse Hinds cables with
either 3,4, or 5 pin connectors, 6 ft., 3-wires (for explosion-proof
versions), 1/2” NPT conduit (Reed Switch types only), or M12x1
Micro 4-pin connection.
A complete list of the cycle and proximity switches with their
available options appears on Page 2.
OPERATION
Proximity Switches are installed in place of an o-ring seal
piston enclosure plug in one of the working sections of a
Series-Progressive divider valve assembly. They are actuated
by movements of the lube-dispensing piston inside the section
and thereby send a signal to the Controller indicating the rate
and amount of activity of the proportioning divider as lubricant is
pumped through it.
Reed type switches utilize a pin attached magnetically to a piston
to cause the switch contacts to close. Field sensing magnetic type
of switches sense the proximity of the pistons' mass to cause
contact closure. When the piston moves in the opposite direction
away from the switch, the Reed switch is deactivated by the
withdrawal of the actuating pin and opens its contacts. Similarly,
the FSM Proximity Switch’s sensing of the piston is lost and it’s
contacts open. The two contact transitions (open-to-closed and
closed-to-open) are detected by the Monitor/Controller, which
has been programmed to interpret such a signal as one complete
cycle of the divider section, and therefore one complete cycle of
the entire SP divider valve assembly.
Depending upon the individual lubrication system’s design and
lubrication requirements, the Controller or PLC programming
then uses the feedback signals from the Proximity Switch in each
lubrication zone to start and stop the lubrication cycle periodically
as required by the system design specifications. If the Controller
or PLC does not receive the expected signal within a time period
specified in the lubrication system’s design, and programmed
into the PLC as the “Monitor Time”, the PLC can initiate various
responses as specified by the user. These responses can include
triggering a local audible and/or visual warning or sending an
electronic notification to a remote computer terminal.

† The FSmech illuminated Proximity Switches (i.e. 527-005-670) are designed to work with controllers and PLCs which
have a typical input impedance of 1500 ohms or less. Using the switch on devices which have an input impedance
about 3000 ohms or larger may cause the input to not recognize a change of state to the closed position. If using a
high impedance input, it is suggested that a 527-006-050 non illuminated FSmech switch be used. If state indication is
required, a connecting cable with LEDs should be used.
