Actions with the activation and programming key (APK)
- Remove the APK from the underside of LUB-S-V.
- Place the APK on the action area on the front of LUB-S-V.
- Remove the APK from the action area as long as the desired menu item is shown in the display.
Settings menu
The Settings menu allows you to change the operating mode and the cartridge size of LUB-S-V. You can switch between hour mode, empty time mode and pulse mode. Being in hour mode, you can change the pause time as well as the number of strokes per lubrication cycle. Running empty time mode, you can change the emptying time in months.
menu and move the activation and programming key back to the action area when Mode is displayed. The double circle appears and the three adjustable operating modes are shown alternately in the display. When your desired operating mode is displayed, remove the activation and programming key from the action area.
PIN assignment
| PIN | Assignment | Colour |
|---|---|---|
| 1 | +24 V DC | brown |
| 2 | input signal (pulse mode) | white |
| 3 | ground | blue |
| 4 | output signal | black |
Type: M12x1 female connector; 4-pin, A-coded
Output signals – hour mode
The output signal at PIN 4 can be tapped for further processing (e.g. indicator light or external control). The maximum permissible current output must not exceed Imax < 20 mA. No inductive load (e.g. relay) may be connected!
| Output signal (PIN 4) | Meaning |
|---|---|
| 0.5 Hz-Square wave signal, permanent | Note E1 |
Empty cartridge
LUB-S-V will not deliver any lubricant!
low, permanent| LUB-S-V is switched off or there is an error (E1, E2, E3, E4).
The error can be read on the display. LUB-S-V will not deliver any lubricant!
high, permanent| LUB-S-V is operating correctly
Input signals – external control (PLC)
To command LUB-S-V via an external controller (PLC) it is necessary to switch LUB-S-V to pulse mode in the Settings menu. In pulse mode LUB-S-V operates as a pulse-controlled lubrication system only if unalterable input signals (high level) are transmitted from the PLC to LUB-S-V via PIN 2 in a defined sequence. LUB-S-V signals the respective status to the PLC via high/low levels which can be tapped off at PIN 4. To operate LUB-S-V via an external controller (PLC) in pulse mode a program corresponding to the communication protocol must be created in the PLC. LUB-S-V provides the following unalterably defined control signals (input signals) which must be transmitted from the PLC to LUB-S-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 +/- 25 ms.
| Signal length in ms | Function |
|---|---|
| 100 ms | 1 stroke |
| 900 ms | Filling function |
| 1000 ms | Cancel Filling function |
| 1600 ms | Status request |
| 1700 ms | Acknowledge error (E2 and E3) |
LUB-S-V in pulse mode PUL only processes the control signals listed in the
table up to a maximum length of 1700 ms. If a highlevel (+24 V DC) exceeds the
defined tolerance level, LUB-S-Vdoes not react. LUB-S-V continues to process
the signal lengths used by devices between 2019 and 2022! (2 seconds: 1
stroke, 12 seconds: Filling
function, 14 seconds: Acknowledge error) The length of the first signal
received determines which control signals it reacts to. A changeover is made
by interrupting the
voltage for a few seconds. Control signal 100 ms Immediately after the control
signal drops the motor run of LUB-S-V starts and 0.15 ml lubricant is conveyed
to the outlet. At the end of a lubrication stroke, LUB-S-V sends a output
signal to PIN 4, which provides information about the past lubrication stroke
as well as other states of LUB-S-V for evaluation at a PLC or other external
control.
Output signals – external control (PLC)
During the transmission of the output signal, the signaling for information
transmission changes several times from a high level to a low level and back
again. The output signal is sent with a frequency of f = 5 Hz. After sending
an output signal, a high level is permanently present at PIN 4. The following
graphic shows an example of an output signal.
Information about the status of LUB-S-V and about the past motor run can be evaluated via an evaluation of the number of edge changes of the output signal. For the evaluation of the edge changes, the rising edge must always be counted. The counted number of edge changes corresponds to a one-to-one state of LUB-S-V.
Number of edge changes|
Information
---|---
1| Filling function canceled
2| Past lubrication stroke OK
3| Past lubrication stroke OK, cartridge soon empty
4| Overpressure (error E2)
12| Cartridge empty (error E1)
14| Over-/undervoltage (error E3)
15| Internal device error (error E4)
16| Inadmissible, undefined control signal received
Maintenance
NOTICE
A used lubricant cartridge must not be put back on LUB-S-V as the integrated stroke counter of LUB-S-V is automatically reset by the cartridge sensor after a cartridge has been removed. Only use full lubricant cartridges.

Commissioning
Mechanical fastening
Fix LUB-S-V mechanically through the M5 female threads or through the M16x1.5
male thread of the lubricant outlet. Pay particular attention to the maximum
tightening torques permissible for the M5 female threads
Electrical connection
To connect LUB-S-V with an external power supply system add a proper
connecting cable to the electrical interface on the bottom of LUB-S-V. (Fig.
3)
DANGER
Damaged or flawed electrical connections or unlicensed hot components lead to heavy injuries or even death.
Power on
Execute Filling function Bleeding of the pump during initial commissioning.
Hydraulic connection
Connect the equipment hydraulically to LUB-S-V. When you connect tubes to
LUB-S-V, make sure that tubes and connectors are installed tightly, cleanly
and correctly. The tube length shall not exceed 4 meters, the inner tube
diameter shall not be lower than 4 mm. Make sure that the end of the tube is
cut straight. Ideally, use tubes prefilled with the appropriate lubricant.
Check the settings on LUB-S-V
Check the required values for the lubrication point at the factory settings of
LUB-S-V and adjust them if necessary. Factory settings: operating mode=hour
mode.
Operation and settings
Three operating modes can be selected. The hour mode allows setting the number of strokes per cycle (strokes) within a pause time (Pause) in hours. Pause times between 1…240 hour(s) and strokes per cycle between 1…10 can be set. The empty time mode allows the emptying time of the cartridge to be set in months (months). Emptying times between 1…24 month(s) can be set. Additionally, LUB-S-V can be embedded into a programmable logic controller (PLC) which sends orders and controls LUB-S-V in
pulse mode. Default settings: hour mode
Pause = 6 The pause time between the start of two cycles is 6 hours. strokes = 1 The number of strokes per cycle is one (1).
Default settings: empty time mode
months = 6 The empty time of the cartridge is 6 months.
Default settings: pulse mode
Pulse mode enables embedding LUB-S-V in an external control (PLC) to command
and control the device
