Configuration

When using the OS32C to detect the hazardous area, the Start/Restart Interlock mode should be
selected; the regulations applying to the machine must also be complied with.
 Safety Distance (Required Depth of Safety Zone)
Always configure the safety zone in such a way that the machine comes to a standstill in a time less
than that taken to reach the danger point of the machine after infringing (interrupting) the safety zone.
The standard ISO 13855-2005 (EN 999-1998) must be used to calculate the minimum safety distance;
according to ISO 13855-2005 (EN 999-1998), the minimum safety distance, S, from the danger zone
area to the outer edge of the safety zone is calculated as follows:
S = (K x T) + C + Z
where:
S = Minimum safety distance in mm measured from the danger area to the outer contour of the safety zone.
K = Movement or approach speed in mm/s (constant K = 1600 mm/s)
T = Delay between interruption of the safety zone and standstill of the machine in seconds consisting
of the sum of t
t = Response time of the OS32C
1
t = Rundown time of the machine (mechanical rundown, reaction time of control system)
2
t = additional time delay for use when multiple zones are used (t3 = 10 ms.)
3
C = Safety constant with C = 1200 mm - 0.4 x H (C 
H = Distance of detection level from reference level in mm
Z = Additional safety factors (maximum measurement error) (Z = Z
Z = The OS32C's maximum measurement error (100mm)
1
Z = Additional error by reflective background (

 Documentation of Configuration Parameters
The person responsible for the set-up must record the configuration parameters, print out and sign the
report.
•Connect the printer to the PC.
•Select the menu "File/Print Configuration" in the configuration software.
•The report is printed out.
•Sign and date the report and file it in a known location which is always accessible.
