Installation
•
Always keep the correctly calculated safety distance between the safety light
curtain and the dangerous parts of the machine.
• Install an extra protective structure around the machine so that the operator
must pass through the sensing area of the safety light curtain to reach the
dangerous parts of the machine.
• Install the safety light curtain in a manner that some part of the operator's
body always remains in the sensing area until the operator has finished
working with the dangerous parts of the machine.
• Do not install the safety light curtain at a location where it can be affected by
wall reflection.
•
When installing multiple sets of the SF4C, connect the sets and, if necessary,
install some barriers so that mutual interference does not occur.
•
Do not use any reflection type or recursive reflection type arrangement.
Equipment in which this device is installed
•
When the safety light curtain is used in the PSDI (see page 134) mode, an
appropriate control circuit must be configured between this device and the
machinery. For details, be sure to refer to the standards or regulations
applicable in each region or country.
•
In Japan, do not use the SF4C as safety equipment for a press machine.
• Do not install the SF4C with a machine whose operation cannot be stopped
immediately in the middle of an operation cycle by an emergency stop.
•
The SF4C provides safety 2 seconds after the power has been switched ON.
Make sure that the control system takes the time delay into consideration.
Wiring
• Switch off the power before wiring the safety light curtain.
•
All electrical wiring should conform to the regional electrical regulations and
laws. The wiring should be done by skilled personnel with the required
electrical knowledge.
•
Do not run the sensor cable together with high-voltage lines or power lines
or put them together in the same raceway.
