7.3.2 Manual Overwriting
When using the Control with Feedback feature, the device checks the feedback in-
dications (i.e. 52-a and 52-b) before and after a control command is issued. If for some
reason, the physical connection from a circuit breaker auxiliary contact to the binary
inputs of the device is broken, inadvertently shorted, or disconnected, commands may
be blocked. If this situation occurs, and the affected switching device is to be operated,
the desired device position indication can be simulated through “manual overwriting”
(Input Tagging). The entered device position indication in the 7SJ62 can be used to
simulate and check interlocking conditions.
To accomplish manual overwriting in the 7SJ62 the binary inputs of the affected device
must be decoupled first. $% (Access Block = Block Input Acquisition) This decoupling
of the system is accomplished by setting the respective status. The decoupling is dis-
cussed in Sub-section 7.3.3.

By pressing the key, a selection window is opened for the marked switch, in
which manual overwriting can be done with the options 23(1&/26(. See Figure 7-
50.
Make the selection using the and keys, and confirm with the key.
