3.1.1.1 Reaction in the Event of a Fault
If the device detects a fault on a digital input, the user program processes a low level in
accordance with the de-energized to trip principle.
The device activates the
FAULT
LED.
In addition to the channel signal value, the user program must also consider the
corresponding error code.
The error code allows the user to configure additional fault reactions in the user program.
3.1.1.2 Line Control
Line control is a monitoring function for detecting short-circuits or open-circuits and can be
configured for the F20 system, e.g., on EMERGENCY STOP inputs complying with Cat. 4
in accordance with EN 954-1.
To this end, connect the pulsed outputs TO 1...TO 4 of the system to the digital inputs DI of
the same system as follows:
EMERGENCY STOP 1
EMERGENCY STOP 2 EMERGENCY STOP devices in
accordance with EN 60947-5-1 and
EN 60947-5-5
Figure 2: Line Control
The controller pulses the pulsed outputs to detect the line short-circuits and line breaks to
the digital inputs. To do so, configure the
Value [BOOL] ->
system variable in SILworX or
the
DO[01].Value
system signal in ELOP II Factory
.
The variables for the pulsed outputs
must begin with channel 1 and reside in direct sequence, one after the other.
In the programming tool, use an assigned variable to set the
DI Pulse Delay
system
variable to at least 500 µs.
If the following faults occur, the
FAULT
LED located on the front plate of the controller
blinks, the inputs are set to low level and an (evaluable) error code is created:
ƒ Cross-circuit between two parallel lines,
ƒ Improper connections of two lines (e.g., TO 2 to DI 3),
ƒ Earth fault of a line (with earthed ground only),
ƒ Open-circuit or open contacts, i.e., including when one of the two EMERGENCY STOP
switches mentioned above has been engaged, the
FAULT
LED blinks and the error
code is created.
