SOFTWARE INSTALLATION
Copy the file ”F39-U1E_ver#.#.exe” and F39-U1E_ver#.#dat from
the 3.5--inch floppy disk (enclosed with the product) onto the hard
disk of the PC.

FUNCTION DESCRIPTION
Start Interlock
When the Start interlock function is used, the F3S-B does not go
to the ON-state automatically after power ON. Interrupting one or
more axes resets the start interlock condition of the F3S--B then
starts normal operation. The duration of the interruption must be
equal or shorter as defined in the »Max. interruption time (sec)« .
Max. Interruption Time
The max interruption time can be set between 0.3 and 2 s.
Note: In the case both the Start interlock and the Start/restart
interlock are selected, only the Start/restart interlock will
be activate.
Start/Restart interlock is a function which is selected by wiring.
Refer to the instruction manual of the F3S-B for more detailed
information.
Relay Monitoring
MPCEs (Machine Primary Control Elements) are usually relays
or contactors used to control hazardous movement directly. The
state of the MPCEs can be checked with the Relay monitoring
function.
A voltage of 17 VDC to Vs (Supplied voltage to F3S-B) has to be
applied to the Relay monitoring input through the NC contacts of
the MPCEs when the F3S-B control outputs are in the OFF--state
(see the F3S-B manual for wiring information). To ensure this
logic relation, the MPCEs must be safety approved types, with
forcibly guided contacts.
J RATINGS AND PERFORMANCE
Allowed Relay Delay Time
The allowed relay delay time can be set between 20 and 300
ms. This delay time has to be set at least 20 milliseconds shorter
than the Outputs ON delay time.
Outputs ON Delay
You can set the ON delay time of control outputs between 80 and
400 ms. This corresponds to the time which the control outputs
go to ON-state after the detection zone is not interrupted.
Note: 1. When the Relay monitoring function is also used, the
ON delay time must meet the formula below.
2. ON delay time ≥ Allowed relay delay time + 20 ms
After the Relay monitoring function is set, if the ON
delay time does not meet the above formula, the
ON delay time will be changed automatically into
Allowed relay delay time + 20 ms.
Blanking
With the Blanking function, one or more axes can be disabled.
This function is useful in an application where a part of the F3S-B
detection zone is always interrupted. The Manual setting and the
Teaching setting are available to select the blanked axes.
Note: 1. In the case the blanked zone is not filled with structure
completely and remains some opening, the opening
must be filled with the protective structure.
2. All axes can not be disabled. At least one axis needs to
be active.
