Fig. 5.10 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 (with a device with the
Alive LED option disabled).
–
On, with one flash per second
(synchronized with that of the
green LED on the device): power
supply and communication with
device present (with a device
with the Alive LED option
enabled)
–
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 x1
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.
Connections are push-in spring terminals,
no tool is required.
For external wiring, cable cross section;
AWG 22-16 / 0,5-1,5 mm
