before handling with this device.
1.3 SYMBOLS USED IN THIS MANUAL
There will be used three identical symbols but with different writings to identify them from
each other.
WARNING!
Imminent danger. It is the highest at the notification scale and requires the
maximum regard.
CAUTION!
Normal danger. It means a medium threat, not as dangerous as a "warning" but
bigger than a simple "attention".
ATTENTION!
Advisory notice. Used as a simple notification that requires a little more care.
1.4 APPROPRIATE USE
This device was developed for safety related usages as part of machinery, whether industrial.
It is the responsibility of the manufacturer of the machinery to ensure the proper functionality
of the safety device.

2.1 DESTINATION AND USE
The Emergency Stop Controls were developed to increase the safety level for the emergency
stop system of the machine. These controls supervises the contacts of emergency buttons,
sensors used in protective grids and other important devices that are vital for the system safety.
The device is meant to go into control cabinets, with its own proper safety level.

3 INSTALLATION AND CONNECTIONS
3.1 INSTALLATION INSTRUCTIONS
The device must be set on a DIN rail by the bottom of the enclosure.
Connect the back of the enclosure onto the rail by its bottom and push it down until it clicks
onto the rail.
The emergency stop buttons to be applied shall be able to carry the maximum output current
of the installed voltage supply unit.
3.2 INPUTS
This device provides two inputs in dual channel system with anti-fraud protection.
One of the inputs provides actuation with positive signal and the other with negative signal (they
cannot be interconnected).
The inputs must be switched on with normally closed contacts, as described in this manual.
These contacts may be emergency stop buttons, electronic buttons, sensors used in protective
grids or any mechanical pulsating button with two NC contacts.
The reset’s Y1 and Y2 inputs must be connected with a normally opened contact such as a
push button or a reset button of any kind.
For a proper connection of the inputs, refer to the appendix of this manual and look for the
figures 1 and 2 of that chapter.
ATTENTION!
It is mandatory to have the contacts properly connected in order to avoid misuses
and even to guarantee contacts’ and device’s integrity.

4.2 OPERATION MODE
After connecting the inputs properly as described on the last chapter (see Section 3.2 INPUTS
on page 3-1, supply the device with rated voltage without deactuating any input (S11-S12/
S21-S22 closed) nor the reset button, the outputs remain in off state.
While in off state, even if the inputs S11/S12 and/or S21/S22 are deactuated the safety relay
will remain off. For the activation of the circuit’s outputs, the reset button must be actuated.
If one or both inputs, S11-S12 or S21-S22, are deactuated, the outputs switch to the off state
immediately.
For a new cycle (new drive), both inputs must be deactuated, to deactivate the outputs, and
then actuated back again. Afterwards, the reset button must be actuated.
