A timing control system is disclosed which is particularly useful in connection with simulated mortar shells. Special circuitry is provided to assure that the shell does not overshoot, but rather detonates early in case of an improper condition; this ensures that ground personnel will not be harmed by a delayed detonation. The system responds to an externally applied frequency control code which is configured to avoid any confusion between different control modes. A premature detonation routine is entered in case an improper time-setting signal is entered, or if the shell is launched before completion of the time-setting sequence. Special provisions are also made for very early launch situations and improper detonator connections. An alternate abort mode is provided to discharge the internal power supply without a detonation in a manner that can be externally monitored, thereby providing a mechanism for non-destructive testing. The abort mode also accelerates the timing function for rapid testing.

A timing control system having an actuator which is intended to be actuated a settable delay period after timing has started, comprising: a timer, an actuation circuit responsive to the timer for enabling an actuation, input means for receiving an input signal having a control frequency, and a timer control circuit which is responsive to the control frequency of an input signal received by the input means within a predetermined time-setting frequency range, the timer control circuit setting the timer to enable an actuation after a delay period which varies according to the control frequency of the input signal within said time-setting frequency range.
