SF4C Safety light curtain
1.2 Safety Instructions
5
•
In case you need to extend the cable of the emitter or the receiver, each can
be extended up to 40.5m by using the exclusive cable. Furthermore, if the
cable is extended and the muting lamp is used, the allowed total extendable
length is reduced (see "Connecting Procedure and Pin Assignment" on page
40).
•
Do not control the device at only one control output (OSSD 1, OSSD 2) (see
page 133).
•
To ensure that the output is not turned ON due to an earth fault of the control
output (OSSD 1, OSSD 2), ground the device on the 0V side (for PNP output)
or +24V side (for NPN output).
Maintenance
•
When you need to replace parts, always use only genuine replacement parts
from the supplier. If you use substitute parts from another manufacturer, the
safety light curtain may fail to detect properly, which may result in death or
serious body injury.
•
The device must be inspected periodically by an engineer with the required
knowledge.
•
When you have adjusted or maintained the SF4C, test the device following
the procedure specified in the maintenance chapter (see page 97) before you
switch the system back on.
•
Clean this device with a clean cloth. Do not use thinner-based cleaners.
Others
•
Never modify this device. If you modify the SF4C, the safety light curtain may
fail to detect properly, which may result in death or serious injury.
•
Do not use the safety light curtain to detect objects flying over the sensing
area.
•
Do not use this device to detect transparent objects, translucent objects or
objects smaller than the specified minimum sensing size.
