JPQ EXPLANATIONS OF TERMS & FUNCTIONS n COUNT OVERFLOW Three overflow modes are selectable with the Programming Unit: Reset, Hold at 00% or Hold at %. In Reset mode, the JPQ resets pulse count to zero as soon as the input reaches the span count value. The span count is equal to the zero count, thus the JPQ never outputs 00% in this sense. In Hold at 00% mode, the JPQ stops counting at 00% input. The count is held at the span count value, and the DC output is held at 00%. In Hold at % mode, the JPQ continues counting until % before holding the count and DC output. In both modes, the Reset command input resets the count to zero and the JPQ returns to the output equivalent to zero count. Input frequency does not affect the pulse counting of this unit, however, the minimum of -microsecond pulse width (0 msec. for mechanical contact input) is required to accurately count the input pulses. Reset Mode Input Output Span Count n ALARM OUTPUT Either Hi or Lo alarm output is supplied by a relay contact. The alarm setpoint and the deadband (hysteresis) are adjustable with the Programming Unit in percentage of the input range. The alarm setpoint is selectable from - to %, while the deadband is from 0 to 0%. Once the relay contact trips, it is reset to the normal position when the counter is reset by the external reset command. n RESET When a reset input is turned on, the accumulated count in the internal counter goes back to zero. The JPQ compares the input to this internal count for the alarm function, therefore is affected by reset operations. The reset input negative is connected to the input common. Short across the terminals and for the minimum of 00 msec. n ZERO COUNT, SPAN COUNT The count value equivalent to 0% output is called Zero Count, while that equivalent to 00% is called Span Count. The zero count is usually set to 0, and selectable up to one count below the span count. The span count is selectable from one count above the zero count up to. When a reset input is turned on, the output goes to 0% according to the reset count. With the Hold at % overflow mode, the maximum count range is from 0 to, and the maximum effective count is.
