Cycle-Indicator 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.

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.
