4.5.4 Submenu “Status”

You can use this submenu to switch “FixedAdjust” and “FirstDrop” ON or OFF (see

paragraph 7.12, page 76 and paragraph 7.11, page 71). If you switch “ON” either of these modes,

the red first drop LED shines until you have performed a successful first drop adjust. If you switch

“ON” “FixedAdjust”, you also need to perform a normal adjust.

With “Cycle Counter”, you can check the cycle count of the dispensing cycles.

“Error” shows the latest error messages of the system (up to 50), depending on the system even

with date and time (UTC). Help to solve error messages you will find in paragraph 11.2, page 151.

4.5.5 Submenu “Scenario”

In the submenu “Scenario” you decide if you want to work with scenarios (see paragraph 7.9.1

"Basics about Scenarios", page 66). You can also enter parameters for pre-defined scenarios. Each

of the four potential scenarios has its own submenu, where you can set those parameters. The

second diagram explains the structure of these submenus. Check there to find the possible limits

for those parameters.

With [→] and [←] you can switch between the four scenarios.

Fig. 8: Submenu “Scenario”

To enter the parameters for a scenario, press [enter] on the respective submenu “Scenario-Def.”

The structure of these submenus is explained in the picture below (see Fig. 9, page 32).

In “Sc:1.1 Setup” you can enter “0”, “1”, “2” or “3” to select a setup or “-”, to decide that no further

segment will follow. “0” is the working configuration, “1” to “3” are the parameters of the

respective setups 1 to 3. Then the scenario will end with this segment and the menu will stop

here as well. (If you later change the “-” to the number of a setup, the following segment will be

unlocked again in the menu.) If you set the blank directly in the first segment, the system will

simply use the working configuration instead of the scenario.

After entering a setup and [→], you can select the Number of Pulses next. This NP replaces the

one from the setup, which would be otherwise used. Another [→] gives the option to enter a

scenario delay. Standard value is 10 ms. Just as with the normal delay, with a heater connected to

the system the minimum scenario delay increases from 0.1 ms to 2.0 ms.

Another [→] brings you to the second segment in your scenario (“Sc:1.2 Setup”), where you have

the same options as with the first. All in all, you can combine up to ten segments (though only

four different setups, since only setups 0 to 3 are available), each with its own NP and scenario

delay, unless you stop your scenario beforehand by selecting “-” instead of a setup. After the last

segment, another [→] brings you the option to set the PLC-Stop “ON” or “OFF”. With “ON” a

scenario always ends automatically, once the trigger signal drops to “low”. No further segments

of the scenario will be performed. With the PLC-Stop “OFF”, the trigger signal only matters, if the

NP in a setup is set as “infinite”. With these parameters will be dispensed until the trigger signal

drops to “low”. If the trigger signal is already “low” when reaching the signal, only one pulse will

be shot. Then the next segment of the scenario will follow after the scenario delay (unless, of

course, it was already the last segment of the scenario).

INFORMATION

Finding PLC-Stop quickly

If you just want to change the PLC-Stop setting, but not any of the segments in your scenario, it is

quickest to use [←] once after entering the scenario, since this submenu is wrap-around, just like

all other.
