In an industrial process of electrolytic bath, the wetted parts need
to be removed from the bath and replaced with new parts every 20
minutes. The process of removing and adding parts to the electro -
lytic bath is automated and takes 15 seconds. During these 15 sec -
onds, the system of electrolytic bath should receive no power supply,
which must be reactivated after 15 seconds, when new items are
immersed in the bath.
The M60-CR chronometer can be configured to activate a relay out
-
put every 20 minutes, and this relay must remain active for 15 sec -
onds. After this time, the relay will deactivate.
Additionally, the system needs the counter to start counting as soon
as power is received, although a 60 seconds delay is needed to give
time to the first activation of the electrolytic bath. Counter must con -
tinue counting from the value it had before the power was removed.

An industrial process has an oven to dry different elements. The dry -
ing time of each element is variable, and the operator requires that
the setting of each drying time to be easily accessible and modifiable.
The modification of other configuration parameters must be locked.
During the process, the operator needs two signals. First signal ac -
tivates a buzzer which should start 5 minutes before the end of the
scheduled drying time, and remain active for 15 seconds. The second
signal must activate at the end of the drying time and must remain
active until the operator manually the ‘reset’ signal.
The M60-CR chronometer can be configured for down counting, with
start time at preset value, which will be directly accessible and modi -
fiable when pressing the front key UP (‘
5
’). All configuration pa -
rameters (except the ‘preset’ value) will be password locked. Alarm 1
will activate for 15 seconds when 5 minutes are missing to end the
process. Alarm 2 will activate when the scheduled time is over and
will remain active until the operator manually resets.
