Configurable functions
Switching operating modes for devices connected via EFI
The status of the operating mode selector switch of the UE 440/470 can be transferred to
a protective device connected via EFI. The operating mode selector switch can be
configured so that operating mode switching of the EFI device …
$
takes places simultaneously with operating mode switching of the UE 440/470.
$
takes places independently of operating mode switching of the UE 440/470.
In the case of simultaneous operating mode switching the status of the operating mode
selector switch of the UE 440/470 is transferred to a EFI device. In this case, both the
UE 440/470 and the connected protective device switch to another operating mode when
switching occurs.
In the case of independent operating mode switching the status is transferred from local
inputs to an EFI device.
Operating mode switching of the UE 440/470 by means of the operating mode selector
switch corresponds to a switching of programs and always leads via a RED state of the
safety outputs at the UE 440/470.
$
When transferring the status of an operating mode selector switch to a device connected
via EFI, the same number of operating modes must be configured there. Ensure that
when a C 4000 or S 3000 is connected, the same number of operating modes are
configured in both it and the UE 440/470.
$
If the status of the operating mode selector switch is transferred via EFI to a safety laser
scanner S 3000, then there is a switching between the monitoring cases. The OSSD of
the S 3000 can remain switched on during this switch, depending on the protective field
status. The OSSDs of the safety controller are switched off, however.
$
Only C4000 Receivers with the following type label entry are to be used: Software
Version 3.28 or higher.
Operating mode selector switch
The operator can switch between the operating modes by means of an operating mode
selector switch.
$
When switching to another operating mode, the OSSDs of the safety controller are
switched off.
$
After switching, the condition of the OSSDs depends on the configured application and
the input signals at their inputs.
Examples: With the internal restart interlock activated, the OSSDs remain switched off
and a reset is required. If an internal restart interlock was not configured, and if no
switch-off conditions (emergency stop, ESPE interrupted etc.) are active at the inputs, the
OSSDs switch on again after the switch to the new operating mode.
As soon as you configure several operating modes in the CDS, the operating mode selector
switch automatically appears in the pin assignment of the safety application. It has as
many inputs as configured operating modes.
The operating mode selector switch must be a (1-of-n) key-operated switch.
You configure whether the operating mode selector switch is actuated with or without
testing (see Section 4.6.2 "Testing of the connected input devices and sensors" on
Page 42).
