The TC505 is available with weekly switching clock.
This optional feature allows you to commence
programmes at a preset time or day of week (e.g.
commence programme 2 on Monday at 01:00 ó
clock). You can enter up to 7 switching jobs. By over
lapping switching jobs functions for instance
automatic reducing temperature at night time become
possible on continuous kilns (heat up kilns weekdays
at 7 AM heat up to 1200°C and bring back tempera-
ture at 5 PM down to 900°C.
By pressing and holding key (8) the TC505 changes to
the mode of entering weekly switching jobs (all
segments of the firing curve (15) light up to indicate
clock switching jobs). Use the keys (16), (17) and (18)
to enter the jobs:
Press key (18) to enter the time (e.g. 23:30). All times
are entered in 24h format. To supress the job enter
„off“ instead of a time (to do so press keys (11) and
„0“). As on entering programmes the last job must be
set to „end“. The last switching job must be set to
„end“ (press key (11) followed by digit key „3“).
Now press key (17) to select the day of week. Further
to the normal weekday selections monday to friday
the TC505 accepts „daily“, „weekday“ and „weekend“.
All settings are entered as abbreviation (0-mon, 1-tue,
2-wed, 3-thu, 4-fri, 5-sat, 6-sun, 7-dly, 8-w/d, 9-w/e).
After pressing key (16) enter the number of the
programme to be commenced when time is reached.
Enter „0“ as programme number to stop a programme.
This feature can be used to stop a programme at a
certain time or day of week.
To enter next switching job enter key (6); key (5)
brings you to the previous job.
After 15 seconds not pressing any keys the TC505
quits the mode of entering switching jobs and returns
to normal operation. All switching jobs are processed
repeatedly until suppressed on setting them to „off“
manually.
