@ Asker Glad you got that sorted.
It briefly crossed my mind it might be something to do with a float but I didn't see how that fitted the Automotive / Cars & Trucks heading. I've never seen it as "floating the till" before in my days as a waiter (but see there are Ghits for it) but as having a float (noun) for the till or putting a float in the till. Note bartenders, waiters etc. usually get "a float" from their manager at the start of their shift as well so they can give change to customers. And they give it back at the end.

I can’t say for sure, perhaps this refers to a HGV driver paying for parking at a machine (like a parking meter) that accepts coins and gives change. If the machine runs out of coins, it displays the message ‘’floating in progress’’ or something along these lines. For example, one of the phrases in my translation was ‘’tube jam’’ – and the client’s clarification read: ‘’Coin Jam within a tube’’ – as in a parking meter.

Who are these instructions meant for? "Floating a till" is something that is done by a shop manager, at the beginning of a trading day.
Related term: the "float" - the small change put in the till before opening the shop.

Hardly something that "users of automatic truck park/truck wash access control system" should be concerned about.

I should have contacted the client in the first place. This is the clarification they provided: ''Floating a till: ensuring there is enough cash in the till to give change to customers''.

Thank you all for your help.

@ Asker I've no problem opening link. But you need more context from client. Otherwise it's pure guesswork
