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.
