I was looking to do exactly that too. I'm not sure about the ACW4, but there's plenty of room on top of the hopper in the Goldline to add that cube hopper. The Siemens programmable relay part would be simple too since they can operate off of and accept the 24V DC wash pulses for payout. I want to eliminate a wash and raise the top one by $1; I could make it give two
tokens for the top wash and one for the lower ones.
I think there is a niche market for them MEP, why don't you package a kit?
I have two coleman vac
token dispensers, They are almost 2K each. But they have a full size hopper and I only have to fill them on a monthly basis. However, if the assembly could be sized to fit into the cashier, a much smaller hopper would suffice beacuse that is opened frequently.
Even after being in a year I still find
tokens in there on a regular basis. In addition I have a few self serve customers that have caught on to looking for them and using them to get free washes. I would love to design some sort of "trap
door" design that would open about three minutes after the
token was dispensed to allow uncollected
tokens to fall back into a container.
One of the problems you run into hooking the unit to the output is when a customer pays while another is washing. It does not dispense until the wash is triggered.
All, in all though the customers really like them. The ones that know about them, anyway.....
