Universal Pulse Dryer
Overview
This article explains the details of Control Type 29 - Universal Pulse Dryer. This reader Control Type allows customization of how the reader sends pulses to a dryer, allowing such things as full-cycle with top-off payments in pulse-controlled dryers.
We recommend that you contact our support team before implementing this Control Type on your readers if it is not currently being used. This control type can only be used if your reader and dryer are currently on some type of pulse-mode control. Serially-connected readers/dryers will NOT work (and generally this is not needed for serially-connected readers/dryers as the benefits of multi-pulse control are included in the serial integration)
To use this method, the Control Type needs to be set to Universal Pulse Dryer [29]
You should see the following set of settings (actual values are just an example)
The general way that this control works is that when the dryer is not running, the reader will charge the card/app the Full Cycle Cost, send X number of pulses, and start an internal timer equal to the Full Cycle Time. While this timer and the dryer are running, if the card/app is applied to the reader again, reader will charge the Top Off Cost , send only 1 pulse, and increment the internal timer by Top Off Time. The reader has no knowledge of the actual dry times programmed on the dryer control; therefore it is up to you to configure the reader Full cycle Time and Top Off Time so that they are consistent with the actual dry times you have programmed inside the dryer.
The above screenshot shows an example of a reader that has a Full-cycle with Top-Off configuration for a dryer programmed for $0.70/5mins (that is, the dryer control adds 5mins of dry time for every pulse). The reader simply sends 3 pulses to start the dryer and then will send one pulse at a time. Note that if your Full cycle cost per unit time is not a simple integer multiple of Top-off cycle cost per unit time, you can customize the exact number of pulses the reader sends using the Number of Pulses for Full Cycle setting.
The Pulse Type setting depends on the actual dryer and the way the reader is wired in. Please contact support if you're unsure. But generally, if you're moving from Control Type 12 to this new Control Type 29, set the Pulse Type to 0. And if you're moving from Control Type type 04, then set Pulse Type to 1.
