General safety instructions Everybody who is in charge of the assembly, start-up, maintenance and operation of the device must read these instructions carefully prior to assembly and start-up of the device at the machine! Furthermore, this manual must always be available at the site of operation! Basic instructions for setup, operation and maintenance can be found below.
Hazards in case of non-observance of the safety instructions Results of non-observance of the safety instructions can be hazards to persons, for the environment and the device. Non-observance of the safety instructions may result in the loss of any liability claims. The non-observance could more specifically result in the following hazards (for example): •...
Inadmissible modes of operation Operational safety of the device is only guaranteed when it is appropriately applied as indicated in the operating and assembly manual. Never exceed or fall below the limit values, as stated in the technical data. Electrostatic discharge Avoid electrostatic discharge! There are electronic components integrated into the devices which might be destroyed by electrostatic discharge.
Intended use The device is only approved for the industrial use. Caution! Only operate the device if it is installed in/at another machine and operated together with it. Only lubricants which comply with the machine manufacturer’s specifications may be conveyed. The device must only be used according to the technical data (see chapter 1 “Technical data”).
Transport and storage Use suitable lifting devices for transport. Do not throw the device or expose it to shocks. Secure the device against toppling down or slipping during transport. The device may only be transported completely empty. Observe all valid safety and accident prevention regulations for the transport. Wear suitable protective equipment if necessary.
Assembly instructions Check the device for possible transport damage and for completeness before the assembly. Any installed equipment for transportation safety has to be removed. Comply with the following conditions when assembling a complete machine from this device and other components. Mind a proper and eco-friendly assembly without impairment of persons’...
Start up Filling with lubricant • Fill the reservoir with clean lubricant at the ventilation filter! • Observe the machine manufacturer’s lubricant details! Only use lubricants according to machine manufacturer’s specifications! • Collect leaking lubricant in a suitable reservoir and dispose it professionally! •...

Functional description 10.1 General The gear pump (1) in the device supplies the lubricant into the main pressure line (3) via the pressure valve (2) when the lubrication cycle is ushered in. Simultaneously, the access to the pressure relief valve (7) is closed by the pressure valve. Activated by the pressure build-up in the line, a metered amount of lubricant is delivered to the lube points by the metering elements (5), which are connected to the pressure line.
10.1.1 Special function information The device is not zero voltage proof. When the voltage is switched off and on again, the device starts a lubrication cycle, also when the reset button / push-button for intermediate lubrication has been pushed. The version with memory module differs from this (see chapter 11.4 “Memory operation”).
Control The device can be ordered optionally with or without integrated control (see chapter 2 “Code”). Notice! The chapter 11 “Control” and its subchapters are only valid for devices with integrated control. 11.1 Settings at the control • Disconnect the power from the device KS 1 KS 2 •...
11.2.3 Monitoring time When the device builds up no pressure within the monitoring time, an error message occurs. Switch position KS 2 Switch position KS 2 5 OFF 5 ON Monitoring time 20 s Monitoring time 60 s 11.2.4 Relubrication time The relubrication time is the delay time of the device after the pressure build-up signal of the maximum pressure switch B2 (KL.

11.3 Operational mode with prelubrication In the operational mode with prelubrication, 4 to 28 prelubrication impulses (preselectable) in shortened time intervals are triggered when the device is switched on. The alarm relay switches to release only after the prelubrication and the device continues to work in the cycle of the set pulse-off time (time- or load-dependent).
11.3.3 Relubrication time in operational mode with prelubrication The relubrication time is the time in which the device remains switched on when the operating pressure, signaled by the pressure switch, has been reached. By this, it is made sure that the operating pressure, which is necessary for moving the metering pistons, is upheld long enough even for remotely built in metering elements.
11.5 Error messages of the control The alarm output, KL. 1, terminals 8; 9 and 10 with potential-free contact, is closed in a powerless state or in error message state from 8 - 9 and opened from 8 - 10. The contact 8 - 10 closes at release. A protective circuit (RC - element) has to be established at an indictive load on the contact.
Maintenance Disconnect the device from electrical energy supply before maintenance or repairs. Only carry out maintenance and repair in complete device standstill and pressureless condition. Check the surface temperature of the device to avoid the risk of burns by radiant heat. Wear heat-resistant gloves and safety goggles! Clean soiled or contaminated surfaces before maintenance, wearing protective equipment if necessary! Secure the device against recommissioning during maintenance and repair work! 12.1...
