5.2.1 Free Locker Mode (with or without Duration of Use Function)
In "free locker" operating mode, the user has the option of selecting a free locker and locking it using their data
carrier. After the locker has been locked, the user cannot occupy any additional lockers within the same locker
group. Only once the original locker has been unlocked can the user lock another locker in the locker group.
Locker groups are used to organize the locks within a system into certain functional blocks, e.g., changing room
lockers, safe-deposit boxes, etc. Different sector numbers are used on the data carriers to distinguish between the
locker groups, which allows two or more lockers from different groups to be used with the same data carrier,
depending on the data carrier storage space.
For data carriers that are configured with an expiry date, the date is checked by the GAT ECO.Lock 7xxx F/ISO. If
the date has passed, the locker cannot be used.
NOTE!
The GAT ECO.Lock 7xxx F/ISO does not automatically adjust to summer/winter time changes. This must
be taken into account when defining the validity or expiry date.
Duration of Use function
Free locker mode also offers the possibility to define a duration of use for each locker. If a locker with this function is
locked with a data carrier, the current time is written onto the data carrier and the time subsequently checked when
the user attempts to open the locker again.
The locker can be locked/unlocked as often as required during the duration of use period. If the duration of use
period is exceeded, the data carrier can no longer unlock the locker. In this case, the user must recode their data
carrier at a central station, e.g., a GAT Info 6800 F with additional coding license (Part No. 193732).
The data carrier must be coded accordingly for the duration of use function (the corresponding config bits on the
data carrier must be set). In addition, the GAT ECO.Lock 7xxx F/ISO must be configured in GAT Config Manager
for the function (see section “6.5.4. Duration of Use”). There are two configuration modes for the function:
Absolute duration of use (“Duration” function)
In this mode, a usage period
(depending on the “Time limit” parameter in minutes or hours, see "6.5.8 Configuration
Settings Table") is configured. After locking a locker, the user must unlock the locker again within the defined
period. The period begins from when the locker was first locked.
Example:
The time is set to 360 minutes. If the locker is locked at 17:00, it can be unlocked until 23:00. If the locker is locked
at 21:00, it can be unlocked until 03:00 of the next day. The duration of use time is reset after the locker remains
open for 60 minutes.
Use up to a specific time after midnight (“Point of time” function)
In this mode, a time is configured up to which the locker can be used every day. After locking a locker, the locker
must be unlocked before the defined time. The usage period starts from the configured time after midnight.
Example:
The time is set to 120 minutes. As the calculation begins at midnight, the locker can be used until 02:00 the
following day regardless of when the locker was locked. If the locker is locked, e.g., at 01:00, it can be unlocked
until 02:00 of the following day. If the locker remains locked past this time, the data carrier can no longer unlock the
locker. In this case, the user must recode the data carrier at a central station.
