Coin-operated Carwash (Holding Bits and Holding
Timer)
Application
The ZEN can be used to change the operating time of a machine, such as a coin-oper-
ated car wash, depending on the number of coins inserted.
If a holding timer is used and holding bits used for the self-holding bits, the remaining
time will not be reset if there are unexpected power interruptions.
In this example, the carwash operates for 3 minutes if one coin is inserted, 6 minutes if
two coins are inserted, and 9 minutes if 3 coins are inserted.
A holding timer is used as the timer.
