1.3 Hardware Connection
WARNING
!
Disconnect the outputs of the F3S-B from the load when program-
ming it using the F39-U1E software and with F39-E1 interface unit.
Failure to do so may result in serious injury.
Do not connect the F39-E1 to a power supply with a voltage higher than
24 VDC +20 %.
Do not connect the F39-E1 to an AC power supply.

1.3.2 Wiring Procedure
1. Connect the F3S-B (see the instruction manual of the F3S-
B for wiring.)
2. Connect the Interface cable (F39-JB1C) to the Interface
unit (F39-E1).
3. Connect the 4 wires of the Interface cable to each appropri-
ate line of the F3S-B.
4. Connect an RS-232C cable to the PC and the Interface
unit.
1.4 Software-Installation
Copy the file „F39-U1E_ver#.#.exe" and F39-U1E_ver#.#dat
from the enclosed 3.5-inch floppy disk onto the hard disk of
the PC.
2. Function Description
2.1 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 inter-
ruption must be equal or shorter as defined in the „Max. inter-
ruption 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 se-
lected, 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.
2.2 Relay Monitoring
MPCEs (Machine Primary Control Elements) are usually re-
lays or contactors used to control hazardous movement di-
rectly. 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 con-
tacts 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 ap-
proved types, with forcibly guided contacts.
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.
2.3 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 inter-
rupted.
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 mon-
itoring 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.
2.4 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-set-
ting 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.
