In order to fulfil the need for a small and easy to install E-stop, Smile has
been developed. The size of the device makes it possible to be installed
wherever you want. With M12 connections or cable and centralised
mounting holes Smile is very easy to install, especially on aluminium
extrusions. Smile is available for E-stops in both dynamic and static safety
circuits i.e. for interfacing to Vital system/Pluto safety PLC and Safety
relays. Each version is available with either one or two M12 connections or
cable. Two M12 connectors are used to enable the connection of E-stops
in series, which is often used with dynamic safety circuits fulfilling safety
category 4. In the top of the Smile Tina E-stop unit, LEDs show the actual
status according to the dynamic system:
Green = everything is OK, Red = E-stop activated.
Flashing Red/Green = Stop activated from another preceding device.
Smile is also available with black push button and used as a safety stop.
See section on safety stops.

Three-position function, Fox 31/32
A safe three-position foot operated device means that:
1. Stop signals are provided in the top and bottom positions.
2. Start/ready signals for separate starting are provided in
a distinct middle position.
3. After a stop in the bottom position a start or clear signal
cannot be given before the reset knob has been operated
and then the pedal pushed into its middle position.
Two-position function, Fox 21/22
A two-position foot operated device means that:
1. A stop signal is provided in the top, or pedal released,
position.
2. A start/ready signal for separate starting is given in the
bottom, or fully depressed, position
Safety cover protects against unintentional actuation.
A robust metal safety cover prevents unintentional machine
start by a person or falling objects, thereby fulfilling the
standards which demand this. The robust aluminium safety
cover can withstand harsh environments.
Safety level
A high safety level is secured by monitoring the pedal´s
double contacts with one of our safety relays.
Furthermore the third ‘emergency’ position
of the Fox 31/32 pedal enhances safety.
