West Control Solutions KS98-1 - Manual (Page 313)

Two-point operation of a programmer (RUNFLIP1.EDG)
As entry of commands via the operating page is not possible with a programmer, if the relevant digital inputs were
connected, the toggle key (fkey:a/m) must be used for realizing the Run/Stop order on the operating page. A monoflop
generates a short pulse on the positive and negative flank.
The external command (key or switch) from the control panel via d1 is also taken via a monoflop. With a key, only d1
(positive flank) is connected, with a switch, d1 and d2 are connected (positive and negative flank). The pulses are taken
to a flipflop, which switches over between Run and Stop.
Weekly timer for a switch-on and a switch-off time (SCHALTUHR.EDG)
Prerequisite: options card B with clock. 3 ADSUs convert the day, hour, minute information from the status block and
the switch-on/switch-off time from VWERT into a minute value. If the time from the status block is higher than the
switch-on time, the flipflop is set, if the time is higher than the switch-off time, the flipflop is reset.
Recipe input via VWERT (REZEPT2.EDG)
Three configuration examples with different restrictions for operation.
The VWERT displays its own outputs, but not the actually selected recipe. Editing of an existing recipe is not possible.
The VWERT displays the selected recipe, but only, when storage was done after editing. The current values disappear
after pressing the Enter key. VWERT has an additional edit function. This bit was applied to the manual input of the
recipe block for output of the currently changed values on the display via the operating page. When storing and switch -
ing over to the next the recipe number (ALLP), the edit mode is reset automatically via OR and AND (due to the han -
dling order).
III-22.2 Controller applications
Minimum controller configuration (C_SINGL.EDG)
Ratio controller with split-range or
three-point stepping controller with position feedback
(C_V_SPL.EDG)
The position feedback input is defined as a potentiometric transducer (which can be calibrated) and linked to the con -
troller with its fail, a/m, inc, dec outputs. The use of process outputs can be configured at the controller and
OUT1/OUT2.
Slave controller for testing the start of internal switching functions (C_SW_SL.EDG)
Circuit proposal for cascade configurations (KASK.EDG)
The master controller correcting variable must follow the slave or process value, when the slave is switched to inter -
nal or manual mode, in order to ensure bumpless return to the automatic mode.
Programmer fragments
Analog output with 4 recipes (2*20 segments 2*10 segments) (PROG.EDG)
Selection of the recipe/program no. is via the VWERT and cannot be selected any more via the programmer operating
page. The ALLP limits the input range.
Caution: the display is correct, however, the edit buffer contains the last output value, which may be too high. Entry of
the preset time is via the programmer operating page. For input of the preset time via a VWERT, the digital connection
(PRESET) must be provided.
Programmer with coupled outputs (PROG2.EDG)
The programmer blocks are coupled for program number, elapsed net time and RUN / RESET commands.
Programmer output with 10 programs with 20 segments (PROGRAMM.EDG)
