List of available logic signals is described in section 7.
4.9. Configuration of magnetic indicators (WSM)
Group “WSM indicators” settings allows for setting of 4 magnetic indicators fitted on
the front panel of the device. The following parameters can be set for each indicator:
-
Active:
allows for switching off the selected indicator on or,
-
Reset:
defines a way of “switching off” the indicator after the energising signal
disappears (after selecting “manual” the indicator will be switched on until the
operator resets it, in case of “automatic” the indicator is reset when the energising
signal disappears),
-
Negated signal:
allows for negating the status of the signal energising the
indicator,
-
Signal No.:
allows for selecting a signal from the list of available logic signals that is
used to set the indicator.
List of available logic signals is described in section 7.
4.10. Configuration of logic gates
The AZT-9 protection device has two 8-input logic gates enabling the extension of
protection functionality. Each of the gates can work as a sum or conjunction and gate input
can be used as a trigger of energy storage, energiser of relays, LEDs, magnetic indicators
or as a signal to the input of the second gate. The following parameters are used to
configure the gates:
-
Type:
defines the logic function carried out by the gate (OR, AND),
-
Number of inputs:
enables determining the number of active gate inputs (max. 8),
-
Negated input:
allows for negating individual gate inputs,
-
Signal No.:
allows for selecting a signal from the list of available logic signals that is
sent to the individual gate inputs.
List of available logic signals is described in section 7.
4.11. Configuration of a disturbance recorder
Group of “Recorder” settings is used to configure the operation of a fast changing
curves’ recorder. The recorder allows for recording samples of measured currents L1, L2,
L3, N, and 64 states of internal logic at sampling frequency of 1 kHz. It enables a detailed
analysis of the disturbance and identification of the device status when the disturbance
occurred, before the disturbance and after ATZ-9 operation. The following parameters are
used to configure the recorder:
-
Total time of recording,
-
Post-trigger recording time.
8 configurable channels can be used to trigger the recorder. For each channel the
following parameters can be set:
-
Active:
activates or deactivates the channel,
-
Negated signal:
allows for
negating the status of the signal triggering a given
channel,
-
Signal No.:
allows for selecting a signal from the list of available logic signals used
to trigger a given channel.
List of available logic signals is described in section 7.
