Description
The HRV combines the accuracy of microcontroller based circuitry
with an electromechanical relay output. The HRV’s switching
capacity allows direct control of loads like compressors, pumps,
motors, heaters, and lighting. The HRV “S” version provides a
vend time after the selected number of initiate switch closures
to start is reached. The HRV “A” version includes all of the “S”
features and allows the total vend time to be extended for
each additional initiate switch closure. The HRV is ideal for cost
sensitive single coin or token vending machines. The electronic
circuitry is encapsulated to protect against humidity and vibration.
Operation
Coin Totalizer & Vending Timer (“S” Version):
Input voltage must be applied prior to & during operation.
When the total number of S1 initiate switch closures equals
the number to start set on the lower 3 DIP switches, the load
energizes and the vending time set on the upper 7 DIP switches
begins. At the end of the vending time, the load de-energizes
and the vending time is reset. Closing the initiate switch during
vend timing will have no affect on vend time delay.
Accumulating Vending Timer (“A” Version):
Input voltage must be applied prior to and during operation.
When the total number of S1 initiate switch closures equals
the number to start set on the lower 3 DIP switches, the load
energizes and the vending time starts. For every initiate switch
closure, the HRV unit adds one time per coin period, as set on
the upper 7 DIP switches, to the total vending time.
Operation Note: If S1 is closed when input voltage is applied, the output remains de-energized
and the S1 counter remains at zero closures. At least one “vend time” and one “closures to start”
DIP switch must be in the “ON” position for proper operation.
Reset: Removing input voltage resets the vend time delay, the
S1 closure counter, and de-energizes the output relay.
