OS32C
21
All safety-related machine control elements must be
designed so that an alarm in the control logic or failure
of the control circuit does not lead to a failure to danger.
Do not use the auxiliary output or warning output for
safety applications. A human body may not be
detected even if a failure of OS32C occurrs, resulting
in serious injuries.
Installation
The main unit must be securely mounted and its cable
connectors must be tightly attached.
A start switch to release interlock must be installed
where an operator can observe the monitored/guarded
zone as a whole and cannot operate the switch within
the hazardous zone.
A protective mechanism must be installed to prevent a
hazardous condition in the event of a subsequent
machine component failure. The OS32C does not
protect against ejected flying material.
Severe smoke and particulate matter may degrade the
efficiency of an OS32C, causing it to unexpectedly
enter a Machine Stop state.
Use of mirrors or mirror-like objects in the protection
plane must be avoided, as they can hide part of the
area to be monitored/guarded.
Additional guarding may be required to prohibit
access to dangerous areas not covered by the OS32C
system.
Perform the test procedure in this document at
installation, after maintenance, adjustment, repair or
modification to the machine controls, tooling or the
OS32C system. Refer to OS32C Series User’s Manual
(Man.No.Z296-E1).
Perform only the test and repair procedures outlined in
this manual.
Additional measurement error resulting from reflective
backgrounds may need to be added to the
measurement error of the OS32C.
To use the protective function of the OS32C, a safety
zone must be properly defined and configured.
If the response time is changed, re-calculation of the
safety distance is required. This may require re-
configuration of the safety zones or re-installation of
the OS32C. If the safety distance is not appropriate for
the application, the machine may not stop before contact with
the hazardous part, resulting in serious injuries or death.
The activation of RBM Only mode will increase the
response time. This additional time must be taken into
consideration when calculating the safety guarding
distance.
When using more than one OS32C, mutual interference
should be prevented. This may require different
scanner positions or physical shields to be installed.
To ensure a protection degree of IP65, DO NOT use
this product without proper sealing of the cable
connector, I/O block, and scan window.
If the external zone switching device momentarily
exceeds the configured number of active zone set
select inputs during the zone switch, an additional
Zone Delay may be incurred in the event that wiring of
a zone set select input fails. The external zone switching device
must properly sequence so the configured number of active
inputs is not exceeded in order to guarantee that failed zone set
select input wiring will be detected within the normal Zone
Switching Time described below.
If an insufficient Zone Delay is used for the actual worst
case switching time of the installation, the scanner
might start monitoring the wrong zone during the
switching period. Also, if an insufficient Zone Delay is
used for the actual worst case switching time of the installation,
there might be a fault condition during the zone switching period.
If tstart (switching start time) is configured without
consideration of TmaxReaction (total maximum
reaction time), object detection within the new safety
zone after switching and turning OFF of the safety
outputs may be delayed.
Monitoring zone parameters are subject to a number of
constraints that include projective consistency,
maximum radius, and angle limits. As a result, an
imported zone may not correspond exactly to the zone
defined in the file. The user must visually verify the imported zone
when the zone coordinate import process is complete. Refer to

(Man.No.Z296-E1)
Wiring connections
Do not connect the OS32C to a power supply with more
than 24VDC + 25% / -30%. Do not supply AC power to
the OS32C, this may result in electrical shock.
For the OS32C to meet IEC 61496-1 and UL 508, its DC
power supply unit must satisfy all of the following
conditions:
• Within rated line voltage (24 VDC +25% / -30%)
• Complying with EMC directives (industrial environments)
• Double-insulation or reinforced insulation between primary
and secondary circuits
• Automatic return for overcurrent protection
• Output retention time of 20 ms or longer
• Satisfying output characteristics requirements of Class 2
circuit or limited voltage/current circuit defined in UL508.
• Power supply complying with regulations and standards of
EMC and safety of electrical equipment in a country or a region
where OS32C is used. (Example: In EU, a power supply must
comply with EMC directives for low-voltage)
To prevent electrical shock, use double-insulation or
reinforced insulation from hazardous voltage (such as
230 VAC).
Cable extensions must be within the specified lengths,
otherwise it may result in a failure of the safety
functions.
