Power down with Soft Shutdown enabled – When the operator
powers down the host PC, the USB signal to the eF-785 turns off. When
the eF-785 no longer detects the USB signal, it shuts down the entire
machine.
Note: When Soft Shutdown is enabled, pulling the USB cord out of the
eF-785 will have the same effect as turning the eF-785 off via the power
switch.
Follow these steps to provide Soft Shutdown functionality in
your machine
1) Select one of the two options that feature host Soft Shutdown
enabled (see the
Configuring Supplementary Options section
below).
2) Configure the host PC BIOS to power up the PC when AC power is
present.
3) Connect the PC to the eF-785 with a standard USB cable.

NABLE FUNCTION
The Post E-Stop Enable function is an extra layer of protection that
serves to provide independent confirmation from the operator that it is
safe to resume normal machine operation after an Emergency Stop (E-
Stop) has occurred.
Consider a typical machine that has several E-Stop buttons on it.
When the machine operator observes that a dangerous condition exists,
he would actuate (i.e. “hit”) the nearest E-Stop button on the machine,
terminating machine operations as a result. When the Post E-Stop
Enable function in the eF-785 is functional, the operator must reset the
E-Stop button to its normal ‘run’ position,
and then press the machine’s
On/Enable button in order for the machine to resume normal operations.
Note: The operator should always follow safe machine operating
procedures and return to a safe operating position prior to any machine
restart. If operation were to
immediately resume after an E-Stop button
was restored to the ‘run’ position, an undesirable, potentially dangerous
operational condition could occur. Always know and follow your
machine’s safe operation guidelines.
Having the Post E-Stop Enable feature enabled is especially important
in cases where it is possible for an operator (or parts of an operator) to be
inside a machine while the interlocks are closed.
For general safety and compliance requirements, Teknic recommends
that you configure your eF-785 with the Post E-Stop Enable feature
activated (options
D and E ) .
The Post E-Stop Enable feature satisfies the ‘Manual Reset’ step
required by EN 954-1. As previously stated, the machine safety design
engineer should perform a complete safety assessment prior to selling
machines with this function disabled.
Read EN 954-1 carefully to
decide if your machine can operate with the Post E-Stop
Enable function bypassed.
During the engineering design and development phases, the Post E-
stop Enable function can be inconvenient. By disabling the Post E-Stop
Enable function, machine operation can resume immediately after an
actuated E-Stop button has been restored to its normal “Run” position,
assuming that the system software is configured to allow this and the
