General configuration of a single-line DuoFlex centralized lubrication system with two analog pressure sensors The following description applies to a 0 VAC two-line centralized lubrication system for industrial use with one lubrication line. The LC50 control unit () is installed in a DuoFlex control cabinet, with load unit and power supply for the pump motor and the connected valves and sensors. One grease supply line () and one grease return line () are flanged to the pump housing of the dual line-pump. These are flanged with their respective ends to a model SSY0 electrical changeover valve (4). Two main feed lines (5) (6) proceed from the SSY0 electrical changeover valve to the dual-line distributors in downstream alignment (7). Ahead of each of the last dual-line distributors of main feed line and main feed line, an analog pressure sensor (8) (9) has been fitted that transmits a signal corresponding to the existing pressure to the control unit (the control unit compares the two signals). The fill level monitoring is carried out by a fill level switch located in the pump reservoir. This switches the pump off when the minimum fill level has been reached. The system version is suitable for greases up to NLGI Grade. Example of a single-line DuoFlex dual-line centralized lubrication system

17 4. LC50- factory setting of a DuoFlex centralized lubrication system Page 7 EN 4.. System design See pages 6, 8 and 9. After the pause time, the pump delivers lubricant through the grease supply line () to the SSY0 electrical changeover valve (4). Depending on the position of the changeover valve (4), the lubricant is then conveyed onward through main feed line (5) or main feed line (6) to the dual-line distributors (7). With continuous delivery, the pressure in the actuated main feed line increases until the resistances in the system have been overcome. Afterwards, the control and metering pistons of the dual-line distributors are actuated. Lubricant is dispensed through the branch lines (0) to the lubrication points or progressive feeders in downstream alignment (). Once all of the distributors have dispensed their quantities of lubricant (control and metering pistons are in their end positions), the first half of the connected lubrication points in section "A" has been supplied with lubricant. Because the pump continues to deliver lubricant, a further pressure increase ensues. Once a pre-defined differential pressure has been reached between the pressurized and depressurized main feed lines (analog pressure sensors (8)/(9)), a switching signal ensues via the LC50. The changeover valve (4) switches over, which means that the previously pressurized main feed line is depressurized while pressure is being built up in the previously depressurized main feed line. The control and metering pistons are actuated once again, lubricant is dispensed once again at this time to the lubrication points or to the progressive feeders in downstream alignment () on the opposite side of the feeders, section "B". Once this process has been run through, one full cycle (x half-cycles) is completed. The pump fill level is monitored by a fill level switch. Error notifications can be shown via an external indicator lamp (connected to error output, in addition to the display).

Example, programming of a dual-line centralized lubrication system with one main line and analog pressure sensors Existing components and factory settings The control unit is factory-set to DuoFlex (dual-line centralized lubrication system). The pump monitoring and pump fill level monitoring are performed by a fill level switch, the pressure in both main feed lines is monitored by one analog pressure sensor on each line. These are mounted ahead of the last dual-line distributor. The DuoFlex system with one main line described in the following consists primarily of the components: 0 V AC dual line-pump unit with changeover valve LC50 control unit, factory preprogrammed for: - DuoFlex single-line centralized lubrication system Pump: <Input 4> => <Function> => <Fill level> => for FF/FB pump for FK pump <Type> => <Mechanics> (Fill level switch for minimum display) <Polarity> => <NC contact> (Default) <Type> => >capacit.> Fill level switch for Min Lubrication line : <Input > => <Function> => <p-switch> => <Type> => <Digital> => <Polarity> => <NC contact> (pressure sensor, main feed line ) or: <Type> => <Analogue> => <Value> <Input > => <Function> => <p-switch> => <Type> => <Digital> => <Polarity> => <NC contact> (pressure sensor, main feed line ) or: <Type> => <Analogue> => <Value> <Input > => <Function> => <ExtDelay> => <Polarity> => <NC contact> <Output > =><Valve> => <Polarity> => <NO contact> (changeover valve, main feed line ) <Output > =><Valve> => <Polarity> => <NO contact> (changeover valve, main feed line ) lubrication line: dual-line distributor one analog pressure sensor per main feed line

21 4. LC50- factory setting of a DuoFlex centralized lubrication system Page EN 4. General configuration of a DuoFlex central lubrication system with one main line with differential pressure switch DDS50/, version 400 VAC See Figure, page /4 The following description applies to a 400 VAC dual-line centralized lubrication system for industrial use with one lubrication line. The LC50 control unit () is installed in a DuoFlex control cabinet, with load unit and power supply for the pump motor and the connected valves and sensors. Depending on the pump version, the changeover valve described below (4) can be attached directly to the pump (grease lubrication pump unit FK, model FK) or, in the case of systems with high operating pressure, separated from the (grease lubrication pump unit FK, model FK). In the case of the latter version, one grease supply line () and one grease return line () are flanged to the pump housing of the dual line-pump. These are fastened with their respective ends to the electrical changeover valve (4) of the model SSY0. The functional description of the changeover valve is the same with both variants. Two main feed lines (5) (6) proceed from the SSY0 electrical changeover valve to the dual-line distributors in downstream alignment (7). A model DDS50/ differential pressure switch (8) is fitted ahead of the last dual-line distributor. This contains two NO contacts. The differential pressure switch measures the differential pressure between main feed lines and. A signal is sent on to the LC50 when a differential pressure of p = 50 bar is reached. Fill level monitoring is performed by an ultrasound sensor located in the pump reservoir. The ultrasound sensor has two switching points. When the fill level minimum is reached, switching point is assigned the task of passing on a signal to the controller, which then switches off the pump. When the maximum fill level is reached, switching point is assigned the task of passing on a signal to the system control unit. This means that an external filling pump can be operated with both signals per system control unit. The system version is suitable for greases up to NLGI Grade.

22 EN Page 4. LC50- factory setting of a DuoFlex centralized lubrication system 4.. System design See Figure, page /4. After the pause time, the pump delivers lubricant through the grease supply line () to the SSY0 electrical changeover valve (4). Depending on the position of the changeover valve (4), the lubricant is then conveyed onward through main feed line (5) or main feed line (6) to the dual-line distributors (7). With continuous delivery, the pressure in the actuated main feed line increases until the resistances in the system have been overcome. Afterwards, the control and metering pistons of the dual-line distributors are actuated. Lubricant is dispensed through the branch lines (0) to the lubrication points or progressive feeders in downstream alignment (). Once all of the distributors have dispensed their quantities of lubricant (control and metering pistons are in their end positions), the first half of the connected lubrication points in section "A" has been supplied with lubricant. Because the pump continues to deliver lubricant, a further pressure increase ensues. Once a permanently set differential pressure level of 50 bar has been reached between the pressurized and depressurized main feed lines, the DDS50/ differential pressure switch sends a switching signal to the LC50. The changeover valve (4) switches over, which means that the previously pressurized main feed line is depressurized while pressure is being built up in the previously depressurized main feed line. The control and metering pistons are actuated once again, lubricant is dispensed once again at this time to the lubrication points or to the progressive feeders in downstream alignment (0) on the opposite side of the feeders, section "B". Once this process has been run through, one full cycle (x half-cycles) is completed. The pump fill level is monitored by an ultrasound sensor.

The pump delivers no lubricant during this time. <Run time> stands for the programmed pump runtime for one lubrication cycle. During the runtime, the pressure is built up and the lubricant is dispensed to the lubrication point. <Dwell time> After receiving the monitoring signal, the pump runtime is ended at once if the dwell time has been set to active. The control unit then goes into the pre-set dwell time. During this time, additional lubricant is pumped into the lubrication point, thus causing the pressure to build up again. At the end of the dwell time, the pump goes into the pause If no pressure build-up notification ensues during the runtime, then the pump goes into error mode after the completion of the runtime. Otherwise, the pump switches over into dwell time. If the dwell time is enabled and set to "0", then the pump switches off after receiving the switching signal and enters into the programmed pause time. After the pause time expires, the pump runtime starts up again.

70 EN Page Operational and pump faults 9. Operational and pump faults 9. Operational malfunctions 9.. General information The operator/operating personnel must perform visual fill level control of the lubricant reservoir at regular intervals. The control intervals depend on the amount of lubricant required and the pump's runtime. The operator/operating personnel must therefore determine the intervals on their own based on the specific conditions of usage. If the reservoir has been pumped empty, the entire system must be bled after refilling (see "Assembly" chapter). 9.. System errors played in plain text. A fault can be selected in the Error menu to view its details. Warning! Determine and remedy the cause of faults before deleting fault notifications. The user is liable for damages resulting from operating the machine without lubrication. 9. Display faults Select the error display menu. Step Key Display English German Info Config Status Lub Fault IO State The LC50 control unit is able to detect a range of different system faults. The control unit activates the red LED as soon as an error is detected.

This can be performed by an external pressure switch (DK, see Chapter..) if desired.

71 9. Operational and pump faults Page 7 EN 9.4 Fault types The control unit issues a malfunction notification with each fault that occurs (see following table). Fault type Definition Display Example of fault Correction (control unit) Fault types Malfunction A fault has occurred that affects the proper functioning of the lubrication system. The lubrication points may not be supplied with adequate lubrication because a malfunction has affected the proper functioning of the lubrication system. Malfunctions must always be remedied immediately. - LED flashes Fill level in the reservoir sinks to the level of the pre-warning sensor (only on systems equipped and configured with this functionality). No pressure build-up during pump runtime No pressure release during pause time. Extend pump runtime or enter delay time. Inspect connections for connection. If no changeover signal is Pressure sensor: o Check pressure sensor connection o Check pressure sensor and replace if necessary 4. Changeover valve does not switch: o Check connection of changeover valve o Check changeover valve and replace if necessary

Operational and pump faults 9.5 Error notification Lub Errors IO State Displayed error notifications Fault notification Category Possible cause Rectification Current error Malfunction o The measured motor current has gone below the limit. Tank gauge error (error in fill level indicator) Malfunction o The fill level sensor of the agitator (W) does not measure pulses after more than 5 seconds, although the pump motor is on. o The analog, capacitive, or mechanical fill level sensor/switch indicates an empty tank even though the lubricant reservoir still contains sufficient lubricant. o Connection interrupted Temperature error Malfunction o This error is reported if the temperature rises above or falls below the maximum or minimum operating temperature, respectively. Output error Malfunction This error is reported if a short circuit or line break is detected at the output. This is a connection error in both cases. To display the specifics of the error, first select the affected output. Remove agitator jamming Check lubricant delivery Check pump fill level Inspect the mechanical fill level switch (W) for proper function and replace if necessary Inspect the connection of the fill level switch and replace the outlet or fill level switch if necessary Inspect the connection of the fill level switch Change the ambient conditions so that a permissible operating temperature is achieved for the control unit/pump (temperature range C) Inspect the affected output connections for short circuit or line break and rewire if necessary.

73 9. Operational and pump faults Page 7 EN Displayed error notifications Fault notification Category Possible cause Rectification Input error Malfunction Different signal sources can be connected to a single input. Errors that are detected on an input can therefore have various causes. A list of possible input errors follows: - Connection error - Pressure error o Connection errors are reported if the signal source configured for the input must conduct closed-circuit current but the measured current is below the expected minimum value. The problem may lie in a cycle switch or an analog or capacitive fill level monitoring sensor. o Dual-line centralized lubrication systems use pressure sensors to monitor the lubrication process. The pressure sensors must report pressure build-up or pressure reduction within a specified time. If the expected signal is not received within expected time, a pressure error on the affected input is reported. Inspect electrical lines and connections of the affected input and replace if necessary Inspect fill level switch of the affected input and replace if necessary Use a pressure gauge to inspect pressure build-up; if the changeover pressure is not present: - Inspect pump feeding and replace pump element if necessary - Inspect changeover valve/connections of changeover valve and replace if necessary - Inspect dual-line distributors for proper function and replace any defective single-line distributor - Inspect main line for leaks, replace if necessary Use a pressure gauge to inspect pressure build-up; if the changeover pressure is present: - Inspect connections of the pressure sensors and replace cable harness if necessary - Inspect pressure sensors and replace if necessary If using an analog pressure sensors, inspect the value range of the changeover point <p-active> This value must be in the range of the pressure sensor (0-00).
