BPS timeswitch program

Function sheet

The VISONIK BPS timeswitch program controls status values and setpoint

profiles in dependence of time, weekday and date for building services plants or

for individual plant elements.

The illustration below represents a sample: Two heating groups (PLT1/PLT2) and one

ventilation plant (PLT3) are to be controlled by individual timeswitch programs.

Timeswitch functions 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. Weekday catalogue WDC The weekday catalogue contains time entries that are dependent on weekdays. These entries represent recurring tasks. MO TU WE TH FR Example: 8891Z02 1 MO..FR !07:00..

Example for menu-guided operation If menu-guided operation was loaded into the VISONIK BPS, the timeswitch catalogues can be edited via a PC connected to the tool interface. The example below is for a WDC entry. The operating program output is indicated in normal print, the user entries in bold print.

Example POP Cards If specified in the scope of delivery, engineering creates project-specific POP Cards such as the "Timer" card for a heating group. This allows for accessing the functions of the TSP timeswitch program. The "Timer" card The following picture shows the "Timer" card on the left and possible display values on the right after inserting the card in the VISONIK BPS card compartment: Project Card Building Process Station Display Time switch prog.
