The following sections briefly describe the main functions of timeswitch catalogues.
They are identical for all operating cards—POP Cards, menu-guided operation, or
COLBAS commands. The samples show individual lines from the COLBAS command
operating mode.
The weekday catalogue contains time entries that are
dependent on weekdays
.
These entries represent recurring tasks.
Example:
1 MO..FR !07:00..18:30 !1
Interpretation:
Line 1 means that each day from Monday to Friday, between 07:00 to 18:30, value 1 is
issued, e.g., as a release command for a ventilation plant.
Use:
For normal occupancy hours on weekdays, Saturdays, and Sundays.
The exception day catalogue contains
date-dependent
time entries. The entries can be
annual or unique events. The events are carried out regardless of weekday catalogue
entries and take priority over WDC.
Example:
2 21-JUN-1999 !18:30..22:00 !1
Interpretation:
Line 2 means that on 21 June 1999, between 18:30 and 22:00, value 1 is output
(unique in this instance, as it is date entry with year indication).
Use:
For special occupancy hours such as evening events.
The entries in special day catalogues assign any weekday to a date. They can be
unique or recurring and impact
all
WDC catalogues.
Example:
Entry in line 1 of a weekday catalogue WDC
1 MO..FR !07:00..18:30 !1
Entry in line 5 of a special day catalogue SDC
5 03-OCT-1999 !SU
Explanations:
– In accordance with the weekday catalogue WDC, command 1 is normally issued for
the respective destination from Monday to Friday between 07:00 and 18:30.
– In the special day catalogue SDC, October 3 (Tuesday) is declared a Sunday. On
this date, no WDC event is carried out, as the WDC catalogue does not contain an
entry for Sunday for this date.
Use:
For public holidays, holidays, and special events regarding all plants.
Using the auxiliary function "Operating hour change“, the operating hours for a specific
destination can temporarily be extended or shortened by a specific amount (T) before
(t
1
) or within (t
2
) the relative operating hour:
8891Z05
14:00 18:00 20:00

The manipulation is unique. It refers to WDC and SDC catalogues of the plant, but
does not change the existing entries of these catalogues.
