INTRODUCTION

At a glance

MEMOLUB CONNECT PRO is an electro-mechanical lubrication system for single-point and multi-point applications. It is available in three grease cartridge sizes (120cc, 240cc, 480cc) and one refillable oil container (OIL-R500, 500cc), making it suitable for both grease and oil lubrication requirements.

The unit operates on a battery pack or an external power supply between 6 and 36 VDC. Its two-component design separates serviceable parts (replaceable cartridge or refillable container, batteries) from the permanently installed settings, allowing maintenance without disturbing the configuration at the lubrication point.

With an ejection pressure of 25 bar, the system covers applications beyond the range of conventional lubrication systems. Using a progressive distributor block (available as an accessory), it supports up to 8 grease points or 12 oil points simultaneously. The unit mounts directly on the lubrication point or remotely via pipe or flexible tubing.

Connectivity and remote monitoring

MEMOLUB CONNECT PRO integrates Bluetooth and LoRaWAN connectivity. The Bluetooth app provides on-site access to device status and settings. LoRaWAN enables full remote access: monitoring, alerts, and settings adjustment from any location. Memolub offers a ready-to-use platform, and integration into customer-owned LoRaWAN platforms is supported.

All-directional, high-visibility LEDs indicate device status locally. The system monitors pump operation, battery level, and cartridge fill level. Alerts are accessible via the Bluetooth app and the LoRaWAN platform, with automatic email notification on alarm detection. Internal temperature is also readable through both platforms. A test button at the base of the unit allows manual verification.

LUBRICATION

There are basically two modes to use the VISIO CONNECT for lubricating an application:

1) Periodic mode: the systems makes an expulsion for each defined period. The period can be set either:

a) Locally on the rotary encoder wheel - positions 1 to 9, with corresponding preset frequencies listed in the "FREQUENCY" section (see next section).

b) Remotely, using the wireless LoRa or the BlueTooth interface *

2) on-demand mode: using the wired connection (6 DIN M16 connector - wires n1 & n2) **


LUBRICATION MODE MIN. OUTPUT MAX. OUTPUT INTERFACE
Periodic 0.17 cc/day 14.4cc/day Local: encoder wheel, stroke washers
Remote: LoRaWAN, Bluetooth
On-demand 0 cc/day 864 cc/day 6-DIN M16 connector

* Local rotary encoder wheel set on position 0. See WIRELESS CONTROL section for detailed information.

** See CABLING and WIRED CONTROL sections for implementation.

WIRED CONTROL

ON-DEMAND MODE

As mentionned in the specifications, single ejections can be triggered by wire control. This section explains the signal requirements for this control to be effective.

Note that periodic and on-demand mode are NOT exclusive: both can be active simultaneously. If you don't want the periodic mode to be active, please set the encoder wheel on position "0" and don't use wireless interfaces.

Finally, on-demand control is more flexible than periodic control and should be implemented carefully, considering lubricant and application particularities. Otherwise, effective lubricant output could not match expected values.

WIRELESS CONTROL

LEARNING PERIOD

The Memolub Connect Pro are equipped with advanced machine learning capabilities, allowing it to account for environmental conditions when calculating its status. A learning period of 20 cycles is required, during which the lubricator must remain in the same environment without any changes to its position, fastening, support, or grease type. If any of these parameters are altered, the learning process can be reset by pressing and holding the pushbutton for more than 5 seconds.

Memolub IOT Home

Platform home

The platform home screen welcomes the user and provides an entry point into the connected device fleet. From here, users navigate to their assigned sites and device groups via the left-hand panel.

Memolub IOT Lubricator Overview

Device overview

The device overview lists all connected units within a site, showing key identifiers such as Memolub ID, location name, lubricant type, cartridge volume, and lubrication frequency. A map view below the list displays the geographic position of all installed units, giving operators an immediate picture of their installation footprint.

Memolub IOT Lubricator Settings

Lubricator Dashboard

The device dashboard provides a full status overview of a single unit, including real-time readings for temperature, battery level, mechanical condition, lubrication flow, and remaining cartridge volume. Device configuration and alarm thresholds are accessible and adjustable directly from this screen. Three remote commands are available: Force Expulsion, Find Me, and Reset Volume.

Memolub IOT Lubricator Alerts

Alarm and event log

The alarm screen logs all alarm events for the selected device, showing appearance and disappearance timestamps for each triggered condition. An event occurrence table alongside it summarises trigger sources and their frequency over a user-defined time period, supporting trend analysis and maintenance planning.

Memolub IOT Lubricator Settings

Settings and alarm thresholds

The settings view exposes sensor parameters and configurable alarm thresholds in a single screen. Thresholds cover cartridge volume, battery level, and temperature, each with warning and critical levels. All settings are adjustable remotely via the platform.

Memolub IOT Lubricator Report

Reports

The report screen presents cartridge volume, battery level, and temperature as separate time-series charts over a user-defined period. Each chart plots the measured value against its configured alarm threshold, giving operators a clear visual reference for how device performance compares to set limits over time.

FAQ

  • Nothing happens after screwing the module on the base.

    • The pin of the module is possibly not proper aligned with the notch of the base. Unscrew the module from the base, align correctly and screw it again.
    • VISIO Module is not tightly screwed to VISIO Base. Turn it clockwise until stop.
    • There is possibly no battery inside the module. Insert 3x 1,5 VDC AA batteries to resolve the issue.
    • There is possibly something obstructing the communication between the base and the module contacts. Unscrew the module from the base, remove any dust or obstacles from the base and the module contacts and screw back together tightly.

  • The touchpad does not work after initialisation was completed successfully.

    Your MEMOLUB® VISIO possibly initialized in an unstable environment. Unscrew the base from the module and screw again to reset the system. Wait until one expulsion is performed and you observe green lights, indicating the initialization is complete.

  • The red lights are blinking periodically.

    • There is possibly a too high back pressure present in the system. Inspect your downstream piping to remove any clogging or jam. Activate the touchpad and check for at least 2 expulsions if the systems operate fine.
    • There is possibly something obstructing the communication between the base and the module contacts. Unscrew the module from the base, remove any dust or obstacles from the base and the module contacts and screw back together tightly.
    • The motor is broken. Replacement of the module is necessary.

  • The yellow lights are blinking periodically.

    • There is possibly something obstructing the communication between the base and the module contacts. Unscrew the module from the base, remove any dust or obstacles from the base and the module contacts and screw back together tightly.
    • The batteries are empty. Replacement of the battery pack is necessary.

  • The blue lights are blinking periodically.

    • The cartridge is possibly out of grease. Replacement of the cartridge is necessary.
    • The system is not primed. Prime the system using a manual grease pump.
    • The system is operating out of its minimum and maximum temperature range. Please make sure the system is operating within the recommended temperature range.
