Accumulating / Totalizing Timer
OPERATION:
Input voltage must be applied and maintained prior to, and during
operation. The HRV unit will count each closure of the initiate switch. When the
total number of closures equals the total number to start (up to 7), which was
set on the lower three DIP switches, the load is energized and the vend time is
started. While running, at every initiate switch closure, the HRV unit adds one
time interval per switch closure, as set on the upper seven DIP switches. Total
time is the time interval set on the upper switches, times the number of closures
set to start on the lower switches.
For example, a total
time of 15 minutes is
desired for a
minimum of two
closures. The "coins
to start" switch
group will have the
"2" switch set to the right, and the time interval
switches for "4", "2", "1" & ".50" will be set to
the right. All other switches remain to the left.
The first closure will cause no immediate action.
The second closure will start the vend, which
will run for the 15 minutes (2 x 7.50 - the
aggregate time of the four switches). If added
closures are made during the run time, 7.5
minutes is added to the remaining time. Up to
260 added cycles may be accumulated in this
manner Total range for the timers is from 15
seconds (.25 minutes) to 31 minutes, 45
seconds (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.

Timers operate equally well at 60 or 50 hz using their own internal oscillator.
All solid state circuitry, deeply potted, with
electro-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.
