  • Page 17: Operation Mode Details

    Figure 12: Mode 1 Timing Diagram Mode 2 – Repeat cycle on input signal When powered on and the input trigger signal is high, the Pulse R™ output cycles at the rate displayed (indicated in cycles per minute) until the input is removed. The rate can be adjusted from 1 to 250. The duty cycle is automatically set by the Pulse R™.
  • Page 18 Figure 14: Mode 3 Timing Diagram Mode 4 – Deliver shots on input signal When powered on and the input trigger signal is high, the Pulse R™ output rapidly cycles to deliver the selected number of shots. Once the input is removed, repeat function. In mode 4 the first digit on the display will be flashing “S”.
  • Page 19 Operation Mode 5 - CDT (Count and Duration Timer) Mode 5 is a count and duration timer mode. The Pulse R™ will count input signals until the programmed count value (cnt) is reached. Once the count value is reached, it will turn on the output for the programmed duration (dur) of time and reset the counter to zero.
  • Page 20 Operation To change the duration value, press and hold the down button for 2 seconds. dur will flash twice and then the value can be changed using the up/down buttons. After 3 seconds of no interaction with the system it will flash dur and save the value. The duration can be adjusted from 0.03 seconds to 250 seconds.
