Input Channels 4 - ABB SPAC 315 C User Manual And Technical Description

Input channels
4...13
The input channels 4...13 are used to read other
binary signals than circuit breaker 4...13 and
disconnector status information. The binary sig-
nals can be external contact signals or internal
binary signals, e.g. start and tripping signals of
protection relay modules. For the definition of
internal and external signals see chapter "Inter-
modular control signal exchange" in the User´s
manual of the feeder terminal.
The status of the binary inputs 4...13 can be
read via the SPA-bus. The status of the input
channels 4...9 is also indicated locally with LEDs
on the front panel. The LED of the activated
input is lit and when the input is deactivated
the indicator is switched off. The indicators of
the input channels 4...9 can individually be set
to be memory controlled by parameter S5,
which means that the indicator of a channel ac-
tivated once for at least 10 ms is not switched
off until it has been reset. As a default the indi-
cators are set not to be memory controlled.
Each input channel can be selected to be active
at high input signal state (1) or at low input
signal state (0) by using parameter S2. High state
activation means that an input is considered to
be active if a voltage is applied on the corre-
sponding external input or if a protection relay
module has activated its output signal. Low state
activation is the opposite to high state activa-
tion. As a default all the inputs are activated at
high input signal state.
Activation and deactivation of the input chan-
nels 4...13 can be delayed by using parameters
S10 or S11 in steps of 20 ms in the range from
0.00 s to 60 s. As a default changes in the input
channel status are not delayed.
Characteristics of input channels 4...13:
- An event is formed by status changes
- The channels can be used to activate the out-
puts OPEN or CLOSE
- The channels can be used to inhibit the out-
puts OPEN or CLOSE
- The channels can be used to activate one of
the outputs SIGNAL1 to 4
- The channels can be included in the interlock-
ing logic
- The channels can be included in the Condi-
tional Direct Output Control logic
- Channel 7 can be used as an energy pulse
counter input, see chapter "Scaling of meas-
ured values".
Via one input channel one signal output (SIG-
NAL1...4) and one control output (OPEN or
CLOSE) can be activated simultaneously. Ac-
cordingly one signal output can be activated and
one control output inhibited simultaneously.
The output to be activated or inhibited is se-
lected with parameters S3 and S4.
The position of the R/L keyswitch is without
significance when the control outputs (OPEN
or CLOSE) are activated via input channels
4...13, but a comparison with the interlocking
logic is always made before a control action.
If an input channel has been selected to control
a signal output, the output is activated as long
as the input is active whereas the length of the
opening and closing pulse is defined by the SPA
bus variables V5 and V6 respectively and they
are not depending on the input pulse length.

If an input channel is used for inhibiting a con-
trol signal the opening or closing of an object is
inhibited as long as the input is active. If the
interlockings are set out of use (S199=0), input
channels 4...13 cannot be used to inhibit the
control of the OPEN and CLOSE outputs.
If input channel 7 operates as an energy pulse
counter input, this input cannot be used for
other purposes. As a default input channels
4...13 operate as ordinary input channels and
are not linked to any outputs.
