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.
