Inverting the logic means that local events are generated while a bay unit is starting
that signal a change of input status that did not take place. Correct operation is
nevertheless unimpaired.
2.2.6.2 Checking the isolator and circuit-breaker auxiliary contacts
Check the timing sequence of the isolator auxiliary contacts by inspecting the
construction of the isolator or assessing it from the respective data sheet.
Verify the operation of the “CLOSED” and “OPEN” contacts
1. According to the circuit diagram and
2. by physically opening and closing the isolator. A check can be done in one
of the following ways
·
Menu item “View
à
Switchgear objects”
·
Menu item “View
à
Binary input/output status”
·
Menu item “View
à
Single-line diagram”.
2.2.6.3 Checking the manual “CLOSE” command
The local HMI is the best way of checking the circuit-breaker “CLOSE” command,
because the signal is generated only briefly and the local HMI is refreshed the
quickest. The corresponding menu item is “Measurements/Inputs”.
Alternatively the circuit-breaker “CLOSE” command can be temporarily
configured as an event and its operation observed in the HMI500 event list.
2.2.7 Checking the binary output signals
Test operations of circuit-breakers and isolators require the
permission of the user and all the prescribed safety precautions must
be observed. Avoid unnecessary switching operations.
All binary inputs are tested by setting them appropriately in the test mode. Select
“Test mode” from the “Testing” menu and clock on “Unblock all relays” in the test
mode dialog.
In the test mode, select “Binary input/output status” in the “View” menu to view
the outputs of a binary module. The status of an output can be changed by double-
clicking on the corresponding field, which then changes to yellow.
