HRV Series Accu Vend Timers

FeaturesAccumulating / totalizing timerAccumulates up to 256 cyclesUp to seven coins to startAvailable in several voltagesIsolated Relay, 20 Amp DPST30 Amp SPST availableFor 60 or 50 cycle currentPrecise digital time settingsSmall, compact, potted electronicsOPERATION:Input voltage must be applied and maintained prior to, and duringoperation. The HRV unit will count each closure of the initiate switch. When thetotal number of closures equals the total number to start (up to 7), which wasset on the lower three DIP switches, the load is energized and the vend time isstarted. While running, at every initiate switch closure, the HRV unit adds onetime interval per switch closure, as set on the upper seven DIP switches. Totaltime is the time interval set on the upper switches, times the number of closuresset to start on the lower switches.For example, a totaltime of 15 minutes isdesired for aminimum of twoclosures. The "coinsto start" switchgroup will have the"2" switch set to the right, and the time intervalswitches for "4", "2", "1" & ".50" will be set tothe right. All other switches remain to the left.The first closure will cause no immediate action.The second closure will start the vend, whichwill run for the 15 minutes (2 x 7.50 - theaggregate time of the four switches). If addedclosures are made during the run time, 7.5minutes is added to the remaining time. Up to260 added cycles may be accumulated in thismanner Total range for the timers is from 15seconds (.25 minutes) to 31 minutes, 45seconds (31.75 minutes) per closure.APPLICATIONS:For the timed control of TV / radio, car wash vacuums, pumps at marinas,campsites, air compressors, water stations, showers, tennis / basketball court lights.AVAILABLE IN: Kept in stock, others may require special ordered, 2-3 weeksTimers operate equally well at 60 or 50 hz using their own internal oscillator. All solid state circuitry, deeply potted, withelectro-mechanical relay for reliability.Standard units will accept loads to 20 amp. Special order units for 30 amp available with com/no poles only on the relay.
