Mainly used in pairs as a two-hand control in applications where it must be ensured that the operator has his hands outside the hazardous area, e.g. for starting a press cycle.

- Ergonomic design

- Several grip possibilities

- Flexible mounting

- Two opposing buttons minimize the possibility to defeat

Used during e.g. troubleshooting, test running and programming, in order to allow the operator to be inside the hazardous area without stopping the machine, while ensuring limited movement and stop in case of danger.

- Ergonomic shape and operation

- Hand recognition prevents defeat

- Easy connection with M12 connectors

- Several models to suit multiple applications

- Extra buttons for e.g. machine control

Different types of control devices

When to use a two-hand or one-hand control device

A two-hand control device is often used for machines with manual loading or unloading. The operator uses the twohand control device to safely start a machine cycle. A twohand control must be used with a safety control device that supervises that both buttons are pressed simultaneously, i.e. both hands are on the control and therefore outside the dangerous zone, in order to start the dangerous movement. An one-hand control device can be used in applications when the operator cannot reach the hazardous area with his/her free hand, or on less dangerous machines.

When to use a three-position device

A three-position device (or hold-to-run device) is used to allow a limited movement of the machine when the operator needs to be in the dangerous area without stopping the dangerous machine, for example during troubleshooting, test running or programming.

The operator pushes the larger black button to a middle position in order to allow a movement. In case of danger, the operator will either release the button or squeeze it to its bottom position and the machine will stop.

Standards

The safety distance of two-hand control devices should be calculated using EN ISO 13855.

When constructing a two-hand station for a machine, the standard EN 574 about functional aspects and principles for design needs to be followed.

One- and two-hand devices

Safeball™

Safeball™ is an ergonomic control device used for safe start and stop of machine cycles. Usually two Safeball™ are used together to form a two-hand control.

Safeball™ consists of a spherical ball containing two embedded push button switches, one on each side of the ball. Both buttons must be pressed in order to start and operate the machine. The risk of unintentional activation is thereby minimized and the device is simple and ergonomic to use.

When two Safeball™ are used in a two-hand device application, the operator must press all four push buttons simultaneously in order

to operate the machine. If one or more of the buttons are released, a stop signal is given to the machine.

Optimum interface

Ergonomic design

The design of Safeball™ allows for comfort of use for all hand sizes and a great variety in gripping positions. And there is no need for shrouding top covers to prevent defeat, as there is for two-hand devices with standard push buttons.

Flexible mounting

With the JSM C5 mounting bracket, Safeball™ can be orientated in the most ergonomic position for the operator.

Applications and features

Safeball™

Applications

One-hand control device

One Safeball™ can be used as an ergonomic “hold to run” button, i.e. the movement is allowed as long as both push buttons on Safeball™ are pressed, usually when the operator cannot reach the hazardous area with his/her free hand, or on less dangerous machines. Safeball one-hand control device since it is very easy to locate and activate.

is a very practical

Two-hand control device

A two-hand control device is often used for machines with manual loading or unloading. The operator uses the twohand control device to safely start a machine cycle. A two-hand control must be used with a safety control device that makes sure that both buttons are pressed simultaneously, i.e. both hands are on the control and therefore outside the dangerous zone, in order to start the dangerous movement. Using two Safeball device.

, it is easy to realize a custom two-hand

Features

Mounting methods

Safeball™ can be mounted in many different ways. It can be mounted on a table, on the machine, on a support or wherever suitable for ergonomic reasons. Safeball™ can be mounted in a fixed position or on a tilting and/or rotating support when used with a JSM C5. This flexibility in mounting enhances ergonomics and minimizes work-related musculoskeletal disorders.

When two Safeball™ are used as a two-hand device, no shrouding top cover is necessary to prevent defeat, as it is for two-hand devices with push buttons, since it is very difficult to push all 4 push buttons of the two Safeball™ with e.g. a hand and an elbow.

Highest level of safety

When used as a two-hand control device, a safety controller for two-hand devices must be used, like an appropriate Sentry safety relay or a Pluto programmable safety controller. The safety controller monitors that all four push buttons (i.e. on each side of both Safeball™) are pressed within 0.5 second, in order to detect e.g. a short circuit or fraud, like a rubber band around one device. Safeball™ is certified to comply with type III C according to EN 574+A1:2008.

JSTD25

The JSTD25 control stations are pre-built two-hand devices utilizing the good ergonomics of Safeball™. They can be used as fixed devices that are easy to install, or as mobile devices. All models are equipped with shields to protect the buttons from accidental operation, and also protect from damage if the device is dropped on the floor when used as mobile device. All versions meet EN 574 and EN ISO 13849-1.
