The safest solution during trouble shooting, programming and testing
Why three-positions?
An operator who is under pressure must be able to give a
stop signal, whether in panic he/she pushes harder on the
button or just lets go of it.
Three-position devices, hold-in and acceptance devices
can be used for trouble shooting, programming and test
running in situations where no other protection is available
or feasible.
If the operator has to enter a risk area to trouble shoot or run
a test, it is extremely important that he/she is able to stop the
machinery without having to rely on someone else to stand
by a stop button that is further away. In addition, no-one else
should be able to start the machinery from the outside after
it has been stopped by use of the three-position device.
Hold to run device or Acceptance device, what is the
difference?
Hold to run device: The start signal is given when the but-
ton is pressed. The stop signal is given when the button is
released or pushed fully in.
Acceptance device: The start signal for separate starting
is given when the button is pressed. The stop signal is given
when the button is released or pushed fully in. “Separate
start” means, for example, that a program start signal is sent
to the robot via a separate button in the acceptance device.
The three-position device is designed to be ergonomic
The device is ergonomic, both in respect of its shape, fitting to the hand, and the way the buttons are operated. It
is easy to operate the three-position device using just the
fingers, and the middle position provides a secure resting
position. The device has LED indications that show the operational status, i.e. stop or ready signal. The two additional
buttons can be used, for example, for start/stop, up/down
or forward/back. Internally the device is duplicated. The
three-position function itself is built up of two completely
independent three-position buttons which are felt by the
user to be one button.
Cheat Safe three-position device with hand recognition
The three-position device JSHD4 has sensors which ensure
that it is a human hand holding it. By using this, the safety
level is increased, and the risk of manipulation or bypass of
the safety function is reduced. It is no longer possible to
expose the operator or odder to danger by trying to lock the
three-position device in run mode.
Three-position device adapted for AS-i
The three-position device JSHD4 also comes in a version
adapted for direct attachment to the AS-i bus

Highest safety level
whether the button is pushed or released
When the three-position button is released you will obtain a dual
stop. It is essential that the machine stops when you put aside the
three-position device, for example during adjustment.

When the three position button is pushed all the way in you will
obtain a dual stop. It is essential that the machine stops in an
emergency situation.
How does a a three-position device work?
Safety level
A safe Enabling or Hold to Run device should function as
follows:
1. The Stop signal in released (top) and bottom position
shall have the same safety level.
2. Provide a ‘Start’ or ‘Ready’ signal in a distinct middle
position.
3. After a ‘Stop’ in the bottom position, a ‘Start’ signal or
‘Ready’ signal is not permitted until the three position
push-buttons have been totally released and again
pressed to the middle position.
This function is achieved mechanically within the three
position push-buttons in the device.
4. A Short or Open circuit in the connection cables
shall not lead to a dangerous function e.g. ‘Start’ or
‘Ready’ signal.
In order to meet the above conditions, the three-position
switch must be connected to a suitable safety relay with a
two channel function, e.g. RT6, RT9 or JSBT4, which can
monitor that both three-position buttons are working and
Released position

that there is no short or open circuit in the connection
cable or the switch.
