Fig. 5.9 Signals and inputs/outputs
of Ekip Signalling 2K-_ -module
1
Power LED, green. The possible
states are:
–
Off: power supply absent.
–
On fixed: power supply and
communication with the device
present.
–
On, with two quick flashes per
second (not synchronized with
those of the green LED on the
device): power supply present,
and communication with device
absent (for example: for Local
Bus disabled)
1)
2
Green
3)
LED for signalling the physical
state of the input H x I
2)
. The possible
states are:
–
Off: floating input
–
On fixed: input short-circuited on
H Cx
2)
3
Green
3)
LED for signalling the physical
state of the input H x2
2)
. The possible
states are:
–
Off: floating input
–
On fixed: input short-circuited on
H Cx
4
Green
3)
LED for signalling contact K x1
- K x2
2)
. The possible states are:
–
Off: contact open
–
On fixed: contact closed
5
Green
3)
LED for signalling the state of
the contact K x3 - K x4
2)
. The possible
states are:
–
Off: contact open
–
On fixed: contact closed
6
Input I x1
7
Conductive part of the inputs H x1
and H x2
2)
8
Input I x2
2)
9
Output contact pin O x1
2)
10 Output contact pin O x2
2)
1)
The absence of communication is signalled immedi-
ately by the power LED, unlike the outputs which
(apart from those programmed to be activated in
the case of disconnection) are deactivated if the
condition persists for at least 8 s
2)
With x = 1, 2, or 3
3)
The LED turns on and off according to the physical
state of the input, without taking any account of
how the Delay parameter is set.
For external wiring, cable cross section;
AWG 22-16 / 0.5-1.5 mm
