1.5. Safety information
The following precautions must be respected for a correct and
safe use of the
SAFE
asy
TM
safety device of the SE4-PLUS
series:
The stopping system of the machine must be electrically
controllable.
This control system must be able to instantly stop the dangerous
movement of the machine during all the phases of the working
cycle.
Mounting and connection of the safety light curtain must only be
carried out by qualified personnel, according to the indications
included in the special sections
(refer to sections 2; 3; 4; 5; 6).
The safety light curtain must be securely placed in a particular
position so that access to the dangerous zone is not possible
without the interruption of the beams
(see section 2 “Installation
mode”).
The personnel operating in the dangerous area must be well
trained and must have adequate knowledge of all the operating
procedures of the safety light curtain.
The TEST/START and TEACH-IN push-buttons must be located
outside the protected area as the operator has to check the
protected area during all the Reset, Test and Teach-in
operations.
The TEACH-IN push-button, if pressed at powering or after the
time-out period during functioning, provokes the safety block
condition of the light curtain.
The Blanking function is signalled, when activated, by a specific
lamp positioned inside the transparent cap on the top of the RX
unit.
The minimum installation distance has to be recalculated if
Floating Blanking is activated, consequently to the resolution
reduction generated by this function
(see section 6 “Functioning
mode”)
. In order to guarantee the correct safety function, the
requirements indicated in section 2.2.1 have to be carefully
respected. Please note that the lamp has only a signalling
function and is not a safety requirement.
The function of the external device monitoring (EDM) is active
only if the specific wire is correctly connected to the device.
Please carefully read the instructions for the correct functioning
before powering the light curtain.
