Page 13: Description Of The Product
Description of the Product General Information The Walther Logic Valve Controller Mini (WLVCM) is a digital real-time control unit for the direct operation of electro-pneumatic spray, dosing or pulse valves from Walther Systemtechnik GmbH. Above that, the WLVCM allows the operation of hotplates from Walther Systemtechnik GmbH which can be optionally added to the employed spray, dosing or pulse valves. -
Page 14: Mechanical Installation
The WLVCM comes with a fixing unit on the back for mounting on DIN profiled rails. The WLVCM will be horizontally installed on the profiled rail using the fixing unit. Please refer to the below figure 1 for the dimensions which have to be considered. -
Page 15: Electrical Installation
Besides the function-relevant electrical interfaces W1 to W7 (see also chapter 6.2.1), the WLVCM also has an optical interface O1 which consists of eight LEDs and displays the current system status on the front of the WLVCM for the user (see also chapter 6.2.2). Figure 2 gives you an overview of these interfaces. - Page 16 6.2.1.1 Interface W1 „Supply Voltage“ A 24 V voltage source is required for operating the WLVCM and its electronics. It will be connected to the clamps +24 V and 0 V at the electrical interface „W1“.
- Page 17 The electrical interface W3 has three digital outlet clamps which are described below and which are used to display the current status of the WLVCM (see also table 4). Each of the clamps at Pins 9, 10 and 11 indicates its status through the two signal levels LOW and HIGH. When signal level LOW is shown, the measurable voltage at the clamp is 0 VDC.
- Page 18 6.2.1.7 Interface W7 „USB“ Parametering the WLVCM will be made through the USB interface. Use it to connect the WLVCM to a Windows-PC where you can run the configuration tool WLVCM. You will need a USB cable with a Type B plug for connecting to the WLVCM.

Page 22: Start Of Operation And Parametering
When you have successfully installed the WLVCM and the configuration tool WLVCM, you can now connect the WLVCM to your Windows PC via a suitable USB cable. Then start the configuration tool WLVCM. Figure 6 shows you the user surface which will appear next and which is explained in detail in chapter 8.2. -

Page 24: Configuration Tool Wlvcm - Area Configuration Wlvcm
After an activation of the heating function through button ➀, the WLVCM will try to reach the preset required temperature. When you turn the heating ➀ off, this will also cut off the power supply to the connected hotplate, and it will cool down to the existing room temperature. -
Page 25: Application Parameters - Overview
If the field “actual temperature“ ➂ does not display any temperature, the heating is not or not properly connected to the WLVCM module. Use the heating control parameters ➃ for setting the PID heating control characteristics. Usually they come as defaults from the factory and are set in such a way that the actual temperature is adjusted to the required temperature with highest precision. -

Page 28: Operating Mode „Sequence Shot
For carrying out the operation mode “continuity shot“ no parameters are required. When the continuity shot is performed, the connected spray, pulse or dosing valve will be opened/activated as long as the shot is performed. It will be closed/deactivated when the continuity shot is finished. Operating Manual WLVCM-BA-10 Page 28 of 37... -
Page 29: Start Parameters
The start parameters in subsection ➄ (see also figure 10) help you to configure the operation mode; the mode will be carried out when the WLVCM receives a respective start signal – the so-called trigger – at the clamps („Start -“ and „Start +“), (see also chapter 6.2.1.6). The following configuration options are available for the parameters “Trigger“... -

Page 31: Test Of Parameters
Once a set of parameters was read from or transferred into the WLVCM, the currentness of each parameter – for heating as well as for application parameters – will be indicated by the symbol to the left. If you make changes to the parameters in the configuration tool WLVCM, the parameter group which you change will delete the symbol. -

- Page 34 Figure 20 shows you an example of an error which is indicated by an applied digital outlet signal „Error“ = HIGH. As long as the digital outlet signal “Error” = HIGH is applied, the WLVCM is not ready for operation and the digital outlet signal “Ready” will be automatically switched to LOW. During this time no application can be started (see also figure 20).
