The closing signal is delivered only once for each activated external closing command
signal. The pulse length of the delivered closing is set with the Close pulse setting.

Figure 496: Determination of the pulse length of the closing signal
In the command control mode operation, there are alarms for a failed closing attempt
(CL_FAIL_AL) and for a command signal that remains active too long
(CMD_FAIL_AL).
If the conditions for closing are not fulfilled within the set time of Maximum Syn time, a
failed closing attempt alarm is given. The CL_FAIL_AL alarm output signal is pulse-
shaped and the pulse length is 500 ms. If the external command signal is removed too
early, that is, before conditions are fulfilled and the closing pulse is given, the alarm timer
is reset.
