• with remote commands via the serial interface RS-232C (see paragraph 8.1, page 83)
Scenarios can also be controlled directly via select pins (see paragraph 7.8, page 68). You have to
set item “Scenario” of the submenu “Scenario” to “ON“. While this is the case, the display shows
“Scenario” where it usually shows the frequency.
7.9.2 Entering Scenarios
To enter the parameters for a scenario you have to go to the submenu “Scenario” (see
paragraph 4.5.5, page 35). To do so, you have to press [enter] in the main menu and then [←]
twice. Confirm with [enter] to reach the item “Scenario”. Press [enter] and use either [↑] or [↓] to
switch between “ON” and “OFF”. Select “ON” and confirm your choice with [enter].
Now you can select the desired scenario with [→] (paragraph 4.5.5, page 35, the diagram for the
submenu “Scenario-Def”). Press [enter]. Enter the first setup (“0”, “1”, “2”, “3” or “-”) and confirm
with [enter]. With [→] you reach “ScNP”, where you can enter the Number of Pulses. For the
scenario, this value will replace the one saved within the setup. Values can be between 1 and
32,000 or “infinite”. Confirm with [enter]. With another [→] you reach “ScDL”, where you can set
the scenario delay. Afterwards confirm with [enter].
Repeat with the second segment, and so on, until you have entered all segments you need or
until you reached the maximum of ten defined segments. When you want to end the chain, enter
“-” instead of the number of a setup. No further segment will be shown in the menu. If you
replace a “-” on a given segment with a correct number, it is unlocked. The system starts with the
setup NP and 10 ms as Scenario-Delay, but you can change these values individually.
With [→] after the last segment you reach “PLCStop” (Scenario-PLC-Stop). After pressing [enter]
you can switch between “ON” and “OFF” (using any arrow key). Confirm your choice with [enter].
(If PLCStop is your only goal in this submenu, it is faster to click [←] once on this level. Like all
other menus, this is “wrap-around”.)
This process you have to repeat for each of the up to four scenarios you want to define.
Scenarios are started with a trigger event. This can be a trigger via keypad, a PLC interrupt or the
“Valve Open” command (without parameters) via the serial interface.
INFORMATION
When no scenario is triggered
Valve-Up/-Down via serial interface and the [F1] key cannot trigger a scenario.
7.9.3 Scenario Selection with Select Pins
Scenarios can be directly controlled via the select pins of the AUX socket (see Fig. 53, page 72), if
“Scenario” in the submenu “Scenario” is turned “ON”. If that is not the case, they switch between
the setups 0 to 3 instead.
With the pins Select_I (AUX socket Pin 5) and Select_II (AUX socket Pin 8) it is possible to switch
rapidly between different sets of parameters. In their blank state, the select pins are on a high
level (pull-ups to 24 V). You have to switch one or both to low (Gnd) to select a different setup
(see Tab. 23, page 72). You have to switch them before triggering.

INFORMATION
Select pins with other commands
Select pins will be checked for triggering via PLC interface, for the serial commands
VALVE:AOPEN and SVALVE:AOPEN (in the versions without parameters) and when pressing the
key [trig].
You can also simulate the select pin settings for these two commands by using the command
extensions “S0”, “S1”, “S2” or “S3” (see paragraph 8.1.2.2 "Explanations", page 88).

7.10 Factory Settings
By recalling the factory settings (implemented by the manufacturer), you return to a predefined
starting position. This is useful to start the input of a new parameter set.
These are the values contained in the factory settings:
RI = 0.50 ms, FA = 0.20 ms, OT = 2.0 ms, NL = 80 %, DL = 10.0 ms and NP = 1.
– Step 1: Press [recall].
– Step 2: [↓] immediately opens this parameter set.
– Step 3: Confirm the selection with [enter].
INFORMATION
Aborting the process
The working configuration (setup 0) is changed to the factory settings. Press [esc] to abort at any
time.
The following table lists the factory settings of the setups.

Tab. 24: Factory settings of the setups
With Setup ALL (see paragraph 4.5.6 "Submenu “Service-Option”", page 37) Setup 4 – 10 get the
same values as setup 0 (working configuration).
The factory settings for all four scenarios are the same. The PLCStop is “OFF”, the other
parameters are shown in the following table.

Tab. 25: Factory settings of the scenarios
You can use the menu to reset changed parameters to their factory settings. Go to the submenu
“Service-Option” and press [enter] at “Service Code“. You can enter the four-digit service code
1000. Confirm it with [enter]. Now you can use the keys [←] or [→] to choose between four
options. You can either reset the setups 0 – 3, all setups, all scenarios or every parameter (“Reset
