2.5 Memory Device for the Master Models
The memory device is a removable memory box included on all master scanner models (not on remote or stand-alone
models). The memory device stores the scanner configuration for an individual scanner or a chain of scanners.
The memory device saves the configuration when the PC transfers the operational parameters to the scanner. This simplifies
the replacement of a faulting or damaged scanner. When the original scanner is replaced and the memory device is
connected to a new scanner, it is very easy to install the configuration on that new scanner (no PC required).
To replace your scanner and/or memory devices, refer to Fast Replacement of the Master Scanner on p. 124
.
The memory device is also the point of cable connections for a master unit. For the cable connection process, refer to
Mounting and Unmounting the Removable Memory on p. 45.
2.6 Reference Points (Surface) Monitoring
The reference points (surface) monitoring function prevents unintentional misalignment and deliberate manipulation of the
SX.
If the configuration contains reference points, the
SX monitors both the Safety Zone (for intrusions) and the reference points
(for position). If the distance between the scanner and the reference surface (point) changes from the configuration (greater
than the assigned tolerance), the SX detects the change and switches the OSSDs to OFF.
The design of the installation and the risk assessment must identify the need and use of the reference points (surface)
monitoring function. In horizontal applications, this function ensures that the safeguarded area does not change due to the
SX moving or changing position because of an impact, vibration, or poor maintenance practices. In a vertical application, the
position of the Safety Zone has a critical effect on the separation (safety) distance. If there is an angular movement of the SX
that causes the Safety Zone to be positioned closer to the hazard, an individual could access the hazard before the machine
can stop.
With a vertical Safety Zone (angle of approach greater than ±30°), it is required that at least three (3) reference points be
assigned. The reference points must be assigned on a surface that will be present but do not have to be at the edge of the
Safety Zone. The surface must be within the safety range for the configured resolution of the scanner. The reference points
should be on at least two sides, areas, or surfaces.
For more information on how to create a Safety Zone and use reference points, see Safety Zone Area - Length and Width on
p. 39.
Note:
• Reference Points
•
Failure to follow these recommendations can potentially create a dangerous situation that may lead
to serious injury or death.
• The design of the installation and the risk assessment must identify the need and use of the
reference points (surface) monitoring function. A change in the position or mounting of the SX can
result in gaps/unmonitored areas and an incorrect (too small) safety distance (minimum distance).
If is recommended that Reference Point Monitoring be used for all stationary applications that have
surfaces that can be monitored.
2.7 Passwords
Improperly set parameters on the SX can cause serious accidents. The configuration of the SX is therefore protected by
passwords.
Banner SX Scanner software is not password protected. Users can create and save (to the PC) a configuration file without
entering a password. A password is required to upload a configuration to a SX.
Ensure that the passwords are secured by the Qualified Person. The default password is admin. Call Banner Engineering
technical support if a password is unknown.
The people responsible for the machine's safety must ensure that the appropriately Qualified Person can properly perform
the tests and work on the machine and the SX in accordance with their intended use.
2.8 Laser Safety (Class 1)
The SX Series Safety Laser Scanner has a Class 1 laser.
