7.1
Process control
If the process control is activated alone, the system carries out a simple on/off function according to
the settings Start time / End time. The indication of the time span refers to the system time used in the
Ser[LOG] (e. g. UTC, MEZ, daylight saving time). In the basic state (set condition not fulfilled) the
respective relay is on contact "S0" (OFF). As soon as the Ser[LOG] is switched on, the relays are
initialized and the Ser[LOG] switches the relays according to the set logic.
If the process control is combined with one of the other functions "cycle control","error monitoring" or
"range monitoring", then the process control limits this function to a certain period of time per day.
Time windows can be selected in which the subordinate switching function is to take place. The pro-
cess control and the other functions are linked to each other with a logical "AND".
Note: The process control is superior to the other functions when used in combination and determines
the working period of the other control functions through the set time window.
The process control is activated via the checkbox "Process control active". In the fields next to the
"Start time" the time in hour (HH), minute (MM) and second (SS) is set, at which the respective switch-
ing channel is set to 1 (ON).
Accordingly, the time in hour (HH), minute (MM) and second (SS) for which the respective switching
channel is set to 0 (OFF) is set in the fields next to the "End time".
The set time always refers to the set local time of the Ser[LOG].
7.2
Cycle control
The cycle control provides a regular switch-on and switch-off function which is repeated at equal in-
tervals. In the basic state (set condition not fulfilled) the respective relay is on contact "S0" (OFF). As
soon as the Ser[LOG] is switched on, the relays are initialized and the Ser[LOG] switches the relays
according to the set logic.
If the process control is combined with the cycle control, then the process control limits this function
to a certain time period per day. Time windows can be selected in which the cycle control is to take
place. The process control and cycle control are quasi-interlinked with a logical "AND".
Note:
Cycle control cannot be combined with error or range monitoring!
The cycle control is activated via the checkbox "Cycle control active". In the fields next to the "Cycle
time", the cycle is set in hours (HH), minutes (MM) and seconds (SS), after which the respective
switching channel is set to 1 (ON). The set cycle times always refer to the full hour, starting at
00:00:00:00.
Note:
The cycle control can be a simple switch-on process for a consumer or the supply voltage for a
sensor, a GSM modem or other system components. When supplying sensors with power, it must be
ensured that the time span set here corresponds to the average times of data acquisition.
The time before the cycle time at which the respective switching channel is set to 1 (ON) is set in the
fields next to "Flow" in hours (HH), minutes (MM) and seconds (SS).
The time after the cycle time at which the respective switching channel is set to 0 (OFF) is set in the
fields next to "Run-on" in hours (HH), minutes (MM) and seconds (SS).
The duration of the switching process (time period) results from the sum of pre run + post run.
