3.2.9 Master and Remote Configurations
Each master can support up to three remote scanners. All the machine communications are done with the master, which
then passes on the commands to the remote scanners. If a remote scanner is blocked, a signal travels back up the chain to
the master, which turns off the master scanner's outputs.
Each remote scanner adds a system latency of 10 ms.
Configuration
Fastest Response Time (ms)
Master only
62
Master with one remote scanner
72
Master with two remote scanners
82
Master with three remote scanners
92
This worst-case response time can be used in all calculations, but it is really the response time for Remote 3. If the master is
blocked, its outputs would turn off in 62 ms since no latency is added going from one remote to the next or to the master.
3.2.10 Shut-Off Functionality
The Shut-Off function allows energy saving, which can be particularly useful when the scanner is used in battery-powered
applications, such as AGVs.
When the scanner is in Shut-Off status, some of its functions are deactivated, but the device is still active and ready to
restore normal operation when needed.
The configuration software does not allow the user to update the firmware version, change a configuration, or set parameters
(e.g. IP address, password) when the scanner is in Shut-Off status.
The Shut-Off function is enabled or disabled on the Zone Set configuration page of the configuration software (see
on p. 82). When the Shut-Off function is enabled, Zone Set 1 is automatically assigned as the Shut-Off Zone
Set (changes from Zone Set 1 to Shut-Off). The Shut-Off Zone set cannot have any Safety or Warning Zones and the
encoder speed range is set to 0.
When the Shut-Off function is engaged (turned on in the scanner), the SHUT-OFF icon shows on the display for 30 seconds.
After that, the display switches to power safe mode and all LEDs go off.
To restore the scanner to normal operation, change the Zone set. The scanner needs approximately 30 seconds to reactivate
all its functions. During this time, the display shows the RES SHUT-OFF icon. After this re-start time, the display and the
LEDs indicate that the scanner is back to normal operation.
Note:
If the Shut-Off function is enabled after Safety and/or Warning Zones have been created for Zone
Set 1, they will be deleted.
Note:
When a cluster of scanners is in Shut-Off status, the removal of a remote unit will result in an
INTF18 (topology error) fault. If the cluster topology must be changed, remove the power.
3.3 Positioning Horizontal Safety Zones for Stationary Applications
Height of the Safety Zone Above the Floor or Walking Surface
— The Safety Zone should not be located more than 1000
mm above the floor H.
Where H > 300 mm, there is a risk that a person can go undetected. In this case, supplemental guarding may be required.
The minimum allowable height of the Safety Zone (H) is a function of the scanner’s detection capability (resolution) and is
calculated using the following formula:
H = 15 × (d − 50 mm)
or
H = 15 × (d − 2 in)
where
d = the Scanner’s Detection Capability (Resolution)
H = the distance of the Safety Zone above the walking surface
Detection Capability (Resolution) (d)
Minimum Height (H)
≤ 50 mm (2 in)
0
70 mm (2.8 in)
300 mm (12 in)
90 mm (3.5 in)
600 mm (24 in)
