Start gate mode

A two-position locking toggle switch selects coincident or anti-coincident operating modes for the starter circuit. During the interval between start gate input signals, the start circuitCoinclocation is enabled or inAntiLocation is disabled.

stop door mode

A two-position locking toggle switch selects coincident or anti-coincident operating modes for the stop circuit. During the interval of the stop gate input signal, the stop circuit is inCoinclocation is enabled or inAntiLocation is disabled.

start

When the start input signal exceeds the threshold, a time transition is initiated. Factory setting is in the negative input position.

stop

When the stop input signal exceeds the threshold, the time conversion is terminated. Factory setting is in the negative input position.

reset/prohibited

Factory setting is in the positive input position.

start gate

Provides an external method of strobing the start circuit in coincidence or anti-coincidence with the start input signal. The start gate input signal must cross the threshold ≥ before the start input signal10 nsAnd overlaps with the trigger edge of the signal. Factory setting is in the positive input position.

stop gate

Provides an external method of strobing the stop circuit in response to or against the stop input signal. The stop gate input signal must cross the threshold ≥ before the stop input signal10 nsAnd overlaps with the trigger edge of the signal. Factory setting is in the positive input position.
