F3SP-U2P
Specifications - continued
Note: 1. Total power consumption must not exceed 24 W, due to an internal self-resetting fuse. This includes: F3SP- U2P 8 W max, muting
lamp 3 W to 7 W and light curtain(s).
2. Refer to the Status Indicator section.
3. A lamp must be connected for operation; shorting this output will cause damage to the unit.
Nomenclature
■Front Panel
Operation
■Dual System
The F3SP-U2P has two independent microprocessors forming
a dual system and can be used with a system up to safety cate-
gory 4. One or two Light Curtains can be connected to the F3SP-
U2P. The state of each of the Light Curtain’s two outputs will be
displayed on four status indicators (Green LEDs). When one or
both safety light curtains are interrupted, the F3SP-U2P opens
both of its safety output contacts.
The F3SP-U2P is equipped with both muting and override func-
tions, forcing system operation regardless of the light curtain
inputs. The muting function makes it possible to disregard one or
both light curtains in order to allow the passage of an object in or
out of a hazardous area without stopping the machine. The over-
ride function allows the system to be manually overridden allowing
material to be cleared from the muting area if a fault has occurred.
Both of these functions force the system to work. Activation of
these functions requires precautions to avoid a reduction in the
level of safety.
The front panel of the F3SP-U2P is equipped with a status indica-
tor (7-segment display) which supplies information on the state of
the controller and on probable cause of failure.
■Basic Functions
Interlock Function
The auto reset mode and the manual reset mode are selectable
features of the F3SP. The selection will be done by dip switch.
Note: For safety reasons, do not change the dip switches while
the F3SP is connected to power.
1. Auto reset mode
The F3SP automatically starts after power-ON and auto-
matically restarts after an object in the detection zone is
removed.
2. Manual reset mode
The F3SP returns to the normal operating mode only after
the object has been removed and the RESET button has
been pressed.
Test Function
1. Self-test: After power ON, the F3SP performs a complete
self-test. In addition, it performs a self test periodically dur-
ing operation.
2. External test: This is used to check if the whole system
works effectively. By pressing the TEST button (see note
below), the interruption of one or both safety light curtains is
simulated. This operation makes the machine stop, so the
system checks can be made according to the established
time and modes.
Note: The test button must be pressed for more than 100 ms.
3. Error detection and restoration (Lockout condition)
If an error is detected by the self-test, the F3SP enters the
lockout condition, keeps the light curtains in their OFF-state
and displays the error code in status indicator. Turning
power ON again or pressing RESET resets the lockout con-
dition.
