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 used to detect short-circuits or open-circuits and can be configured for the remote
I/O, e.g., on EMERGENCY STOP inputs complying with Cat. 4 and PL e in accordance with
EN ISO 13849-1.
To this end, connect the digital outputs DO 1 through DO 8 of the system to the digital inputs
(DI) of the same system as follows:
DI 3
DO 1
DI 1
1 2
2
2 4
EMERGENCY STOP 1
EMERGENCY STOP 2 EMERGENCY STOP switches in
accordance with EN 60947-5-1 and
EN 60947-5-5
Figure 2: Line Control
The remote I/O pulses the pulsed outputs to detect short-circuits and open-circuits on the lines
connected to the digital inputs. To do so, configure the
Value [BOOL] ->
system variable in
SILworX or the
DO[0x].Value
system signal in ELOP II Factory. The variables must begin with
channel 1 and reside in direct sequence, one after the other.
If the following faults occur, the
FAULT
LED located on the front plate of the device blinks, the
inputs are set to low level and an (evaluable) error code is created:
 Cross-circuit between two parallel wires.
 Invalid connections of two lines (e.g., TO 2 to DI 3),
 Earth fault on one wire (with earthed ground only).
 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.
