Depending on the scope of delivery you must also carry out the following additional measures for first-time commissioning: 1. Mechanical fastening Fix LUB-V mechanically. Pay particular attention to the maximum tightening torques. 2. Electrical connection Connect LUB-V with an external power supply system (e.g. PLC) by adding a proper connecting cable to the electrical interface on the side of LUB-V.

  • Page 19: Operation And Settings

    Operation and settings General information What you should know about operating and setting LUB-V: LUB-V is suitable as a multi-point lubricator for one or two lubrication points. However, depending on the specific application, LUB-V can also reliably and cleanly supply a limited number of lubrication points with lubricant. Accessories from the manufacturer (e. g. splitters or progressive distributors) can be connected to LUB-V.

  • Page 20: Factory Settings

    Factory settings LUB-V is always delivered with the following factory settings: operating mode: hour mode -h- mode: OFF LUB-V is switched off The factory settings provide the use of LUB-V in hour mode -h-. If you would like to  operate LUB-V in impulse mode PUL you have to make changes in the SET menu of LUB-V (chaper 6.3.8).

  • Page 21: Pulse Control Mode Pul

    6.2.2 Default settings, operating mode: impulse mode PUL Impulse mode PUL enables embedding LUB-V in an external control (PLC) to command and control the device. The number of strokes (one stroke=0,16 cm³) dispensed now depend on the PLC’s signals. Ensure that your PLC program is appropriate for your application and that the lubri- cation point is supplied with the correct amount of lubricant per time unit.

  • Page 22: Menu And Lcd Messages

    Menu and LCD messages The LCD of LUB-V can be used to read information, to change settings with the activation and programming key on the top of LUB-V or to trigger individual actions. Generally, settings can be changed and actions can be triggered when LUB-V is switched off (OFF) and when it is switched on (ON).
  • Page 23 The graphic above illustrates the unchangeable basic flowchart of the LUB-V menu navigation as well as the options for branching to submenus.  LUB-V can be switched on and off at several points in the menu navigation. For details see chapter 6.3.3.  The INF menu can only be accessed from OFF mode (LUB-V is switched off). The INF menu provides you with an informative overview of the current LUB-V settings.

    6.3.8 PRO menu: Changing the operation mode The PRO menu allows you to change the operation mode used. You can switch between hour mode -h- and pulse control mode PUL. While hour mode -h- is preset you have to make changes in PRO menu in order to run pulse control mode PUL. There is no fault or error at LUB-V.
  • Page 37 Changing the operation mode: If you want to change the operation mode, move the activation and programming key back to the action area. The yellow LED lights up and the next higher (h + 1) adjustable value of pause Ü time h is displayed in the LCD.

  • Page 38: Fil Menu

    6.3.9 FIL menu The FIL menu allows you to trigger a defined multiple dispense of LUB-V. The activation initiates a total of 40 pump strokes. This function enables you to prefill connected acces- sories (tubes, distributors,...) with the lubricant contained in the lubricant cartridge, especially during the initial start-up of LUB-V. However, the process can also be aborted manually at any time. There is no fault or error at LUB-V. Remove the activation and programming key from the top of LUB-V and place it on the action area.

  • Page 39: Error Codes

    During the dispensing process the green LED lights up; in addition, the stroke's  counterpressure is displayed in the LCD. The FIL menu can only be reached from ON mode (LUB-V switched on). When you  enter the FIL menu you will return to ON mode, even if you cancel FIL prematurely with CLR.

  • Page 41: Output Signals At Pin 4 - Time Control

    Output signals at PIN 4 - time control LUB-V provides two output signals in hour mode -h (factory setting) via the electrical in- terface. If required, the operating states of LUB-V can be processed externally. Basically, the output signals can only be sampled and must not be subjected to inductive loads or low ohmic loads.

  • Page 42: Input And Output Signals - External Control (Plc)

    Input and output signals - external control (PLC) To command LUB-V via an external controller (PLC) it is necessary to switch LUB-V to pulse control mode PUL in PRO menu (chapter 6.3.8). In pulse control mode LUB-V operates as a pulse-controlled lubrication system only if unalterable input signals (high level) are transmitted from the PLC to LUB-V via PIN 2 in a defined sequence. LUB-V signals the respective status to the PLC via high/low levels which can be tapped off at PIN 4 and thus enables comprehensive control or, by suitable...

  • Page 43: Input Signals - External Control (Plc)

    Input signals - external control (PLC) LUB-V provides the following unalterably defined control signals (input signals) which must be transmitted from the PLC to LUB-V via PIN 2 of the electrical M12x1 interface as high level (+24 V DC). The control signals must be generated as high level (+24 V) by the external controller (PLC) over certain times with a tolerance of +/- 0.1 seconds.

  • Page 44: Control Signal 2 Seconds

    8.2.1 Control signal 2 seconds The control signal 2 seconds triggers a single dispensing process. After a specified pause time this control signal can be repeated or another control signal can be sent. The operating states are output by LUB-V via PIN 4 as a high/low level and must be tapped and processed accordingly by the PLC.
  • Page 45 Description: LUB-V is properly connected to an external controller via the electrical interface and connected to the power supply. Pulse control mode is activated on LUB-V and PUL is displayed on the LCD. There are no errors; LUB-V is ready for operation; the green LED in the LCD flashes once every 5 seconds. LUB-V sends a permanent output signal (high level) to PIN 4 which indicates to the external control (PLC) that it is ready for operation.

  • Page 46: Control Signal 12 Seconds

    8.2.2 Control signal 12 seconds The control signal 12 seconds triggers the FIL function (section 6.3.9) by the external control. A total of 40 dispensing operations are carried out automatically one after the other. After a certain pause time this control signal can be repeated or another control signal can be sent.
  • Page 47 Description: LUB-V is properly connected to an external controller via the electrical interface and connected to the power supply. Pulse control mode is activated on LUB-V and PUL is displayed on the LCD. There are no errors; LUB-V is ready for operation; the green LED in the LCD flashes once every 5 seconds.

  • Page 48: Control Signal 14 Seconds

    8.2.3 Control signal 14 seconds The control signal 14 seconds is used to acknowledge error messages of errors E2 and E3. It is the only control signal that LUB-V can process when a low level output signal is sent. Regardless of the basic principle of remotly acknowledging an error it is essential to identify and eliminate the cause when an error message is present.

    8.3.1 Error E1 (empty level) - external control (PLC) LUB-V is equipped with a sensor which detects the empty level of the lubricant cartridge. After reaching the empty level, LUB-V no longer dispenses lubricant. This ensures that no air enters LUB-V or the lubricant lines. The empty state message (error E1) is trans- mitted to the external control (PLC).
