Muting sensors must be positioned so that they cannot be activated inadvertently
by personnel.
The muting lamp for indication "active muting" or "active override" must be
positioned in a place where it can be seen from any operative point.
Be sure to use the incandescent lamp for the muting lamp and the replacement
light bulb.
Do not use LED lamp. Failure to do this may cause the F3SP to fail to detect the
breakdown of the muting lamp and may result in serious injury.
The TEST and RESET buttons must be positioned in such a way
- that the operator can see the protected area when he carries out reset, test, or
override operations.
- that it can not be activated from inside the hazardous area.
Always use the two OSSD outputs to configure the safety system.
Using only one OSSD of the safety system may result in serious injury when there
is an output circuit failure.
Do not connect the F3SP to AC or DC power supply with higher voltage then
nominal 24VDC.
Configuration of dip switch is must only carries out by qualified person.
A qualified person, as determined by regulations, must confirm that installation
and inspection are implemented correctly.
Do not use the F3SP until the final inspections are completed (see chapter 5).
Failure to do so may result in loss of life or serious injury.
DC power supply units must satisfy all of the conditions;
•
The power supply voltage must be within specified ratings (24 VDC ± 10 %).
•
The power supply is connected only to the F3SP, light curtain, and muting
sensors. The power supply must not be connected to other devices or
machines.
•
The power supply uses double or reinforced insulation between the primary
and secondary circuits
•
The power supply automatically resets overcurrent protection characteristics
(voltage drop).
•
The power supply maintains an output holding time of at least 20 ms.
•
FG (frame ground terminal) must be connected to PE (protective earth) when
using a commercially available switching regulator.
•
The power supply must have output characteristics of Class 2 Circuit of
Limited Voltage-Current Circuit as defined in UL508
•
The power supply must conform to regulatory requirements and standards,
regarding EMC and electrical equipment safety, of the country where the
F3SP is installed and where machinery will be operated. Example: The EMC
Directive (industrial environment) and the Low Voltage Directive in EU.
