UPPORT
The eF-785 can be configured so that AC power to mechanical hazards is
controlled independently in two different functional areas of a machine.
This means that an operator can easily power down the mechanical
hazards in one part of a machine (Load Area) while the Main Area of the
machine continues to process material, samples, etc, allowing an
operator to feed and retrieve material from the machine while it
continues to do useful work. This can result in a significant,
demonstrable throughput advantage on many automated machines.

The eF-785 has specific outputs that control any installed guard-locks
that open guard doors when hazardous power is removed from a given
machine area. These guard-locks are controlled by user software
and
electromagnetic logic control. To open guardlocks, two things must
occur: 1) the user software must issue an “open guardlock” request and 2)
removal of hazardous power must be confirmed by the electromagnetic
logic control.

The monitoring systems within the eF-785 perform several functions:
they monitor the e-stop and interlock switches (and wiring) for faults,
continuously check the contactors for the proper electromagnetic status
of the hazardous power and guard-lock power. In the event that the
monitoring system detects any errors during operation, it reinforces the
removal of power (which is enforced by the electromagnetic logic control)
and reports the errors to the host computer.
The eF-785 has two important safety diagnostic functions. One
function forces the user to perform a safety test of the e-stop and
interlock switches at each power-up cycle. Periodic checking of these
switches is required by EN 954-1 and this mechanism makes the
procedure automatic. This function removes the requirement for writing
and enforcing periodic inspection procedures and attaching placards or
writing custom software to instruct operators. This function can be
disabled during machine development.
The eF-785 firmware also maintains data on the complete state of the
safety control system just before and after a fault is detected. This
information can help pinpoint the fault to a few possible failures,
speeding up root cause identification.
