4.1.2 System design

A main lubrication line (7) leads from the pump element (2) to the master distributor (8). From there, secondary lubrication lines lead to both secondary distributors (10). The second-ary distributors are connected to the lubrication points by lubrication lines (11). The pump fill level is monitored by a pump-side mechanical fill level switch <Agitator>; the main line is monitored by a cycle switch (9). Error notifications can be shown via an external indicator lamp (6).

4.3.1 Control inputs

The ProFlex standard pump contains a maxi-mum of 4 control inputs. By default, they are assigned as follows:

Input 1

Functional monitoring of the main line by

cycle switch

The main line is monitored by a cycle switch (<CycCount> attached to the master distribu-tor. This switch transmits movement of the distributor piston during the pump runtime <Runtime> to the LC502 control unit as a number of cycles. The LC502 control unit compares the received (counted) cycles <RX> to the expected (programmed) cycles <EX>. If the received cycles are attained in a pre-pro-grammed pump runtime <Runtime>, the pump switches off and enters the pro-grammed pause time <Pause>. <Input 1> => <Function> <CycCount>

Input 2

-Cycle Counter 2

This input is used for the cycle switch in main line 2 on systems with two main lines. <Input 2> => <Disabled>

Input 3

External DK (pressure switch)

External pressure switches can be used to trigger a custom interim lubrication indepen-dent of the LC502's settings. <Input 3> => <External DK>

Input 4

Fill level monitoring of pump reservoir

A fill level switch (W1) on the agitator can con-trol and monitor the pumps. This switch counts the rotations of the agitator and sends this information to the control unit. This allows the pump runtime to be ended after the pre-set number of rotations is achieved. On pro-gressive centralized lubrication systems, this switch is used to monitor the fill level of the lubricant. <Input 4> => <Function> => <Level SW>, type <Agitator>

outputs

4.5.1 Control outputs

The ProFlex standard pump contains a maxi-mum of 2 control outputs. plus an error out-put for triggering a possible fault signal. By default, they are assigned as follows: Output 1 and Output 2 = Disabled

On a system with two main lines, a change-over valve is assigned to each of the two out-puts for pressure build-up/pressure relief of line 1 and line 2. Error Output = N Closed

If an error is present, an output signal is is-sued to an external evaluation device/display via this error output. The output is programmed as a normally closed contact.

<Pause> stands for the programmed pause time of the control unit for a full cycle. During this time, the pump does not feed any lubri-cant. <Runtime> stands for the programmed pump runtime for a cycle. During this time, the pump feeds lubricant. After the pause time elapses, the pump run-time starts again.

Both menu items are only enabled

when a value has been entered

in the menu <Trials> (block mode).

<Pause2> stands for the pause time in block mode. It is the time between runtime and dwell time as well as between the dwell intervals.

<Dwell time> If a pump dwell time has been programmed, once the runtime elapses and in the absence of cycles the control unit enters pause time 2 <Pause2> and then the dwell time. The pump continues to feed until the dwell time ends. Thereafter, the control unit returns to pause time 2. After this time elaps-es, it returns to dwell time (when <Trials> = 2). If the pump receives the outstanding cycles in the interim, the control unit immediately en-ters the regular pause time <Pause>.

If the system is configured for Trials => Block mode, the menu Pause times, run times, and dwell times(Chapter5.1) will show an additional pause time <Pause 2> and dwell time <Dwell>, the setting times for trials = block mode.

In the Trials menu items, only the number of trial attempts is entered for the event that there are outstanding cycles once the actual pump runtime elapses. Block mode ensures that lubrication continues to be performed in the absence of a cycle signal. This is set via the menu items Pause2 and Dwell and for a time until the corresponding number of cycles has been reached or the number of trials has been worked through.

5.3 Limiting and monitoring the pump using a cycle switch


By default, the centralized lubrication system is monitored by one or more cycle switches. This is usually attached to the main distributor and transmits the number of delivery strokes performed to the LC502. The cycles are evalu-ated via the <Monitor> menu or alternately via the <Imm. Stop> or <Col. Stop> menu. The menu <Monitor> is enabled by default. Here, the number of cycles that must be attained during the pump runtime is specified. If block mode is enabled (see Chapter 5.2) and the target value is not achieved during the pump runtime, the block mode is enabled using <Pause2> and <Dwell time>. A report is gen-erated if cycles are missing at the end of the runtime and (if applicable) block mode.

<ExtDelay> (pause extension):

If the pause extension is activated, and the si-gnal is active at the respective input, then the pause time of the lubrication system will be interrupted for as long as the signal remains active. Once the signal ends, the pump will re-sume the normal lubrication operation.

If the system is currently in run time, then this will first be concluded before the pause exten-sion takes effect.

< ExtStop> (Stop input) :

If the stop input is activated, and if the signal is active at the respective input, then the lubrication system will stop at once. The lubrication cycle will be interrupted for as long as the signal is active. Once the signal ends, the pump will resume the normal lubrication cycle.

The stop input stops the system, no matter whether it is currently in pause or run time.

In the case of MonoFlex systems which are currently in run time, the pressure increase is interrupted and the remaining run time is possibly not sufficient to build the pressure up completely once again. This leads to an error message

6. Options for customer adjustment of a progressive centralized lubrication system with two main lines

Compared to a progressive system with one main line, controlling a progressive system with two main lines requires two changeover valves that control both lines independently of each other.

By default, Output 1 (line1) and Output 2 (line 2) are assigned to the two valves and their function <Polarity> is defined as <N Open> for both. The options for customer adjustment of a sys-tem with two main lines are identical to those of a system with one main line. In a system with two main lines, <Line 2> is displayed in addition to <Line 1> under the Settings configuration menu. You must change from <Line 1> to <Line 2> prior to selecting the adjustable menu items.

Input error

- Connection error

- Cycle 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 errors are reported if the signal source configured for the input must conduct closed-circuit current but the measured cur-rent is below the expected minimum value. The problem may lie in a cycle switch or an analog or capacitive fill level monitoring sensor.

Progressive systems can monitor the lubri-cation process using cycle switches. At the end of the pump runtime and the dwell time (if applicable), a check is performed as to whether all expected cycles were counted. If expected cycles are missing, a cycle error will be issued on the inputs with missing cycles.

• Inspect electrical lines and connections of the affected input and replace if necessary

• Inspect cycle switch or fill level switch of the affected input and replace if necessary

• Check the master distributor of the affected input, replace if necessary

• Inspect cycle switch of the affected input and replace if necessary

• Check entry of the programmed number of cycles; it must be proportionate to the pump runtime.

Mon+Stop Mon+Stop Runtime limitation based on agitator rotations, with monitoring by cycle switch. An error is reported when the pre-set value is reached and cycles are missing.

Monitor Monitor Cycle switches that are monitored during pump runtime. A report is generated if cycles are missing at the end of the runtime and (if applicable) block mode.

Imm. Stop (immediate stop)

Sof. Stop (Sofort Stopp) Lubrication is stopped as soon as the expected cycles are received on the input. No report is gener-ated if cycles are missing on other inputs. This function is also used for the agitator.

Col. Stopp(collective stop)

War. Stopp(Warten und stopp)

An input with this setting monitors other inputs. Lubrication is stopped as soon as the last expected cycle is received on the input and on all other inputs. The input with this setting waits for the last missing cycle on other inputs before it stops lubrication. A report is generated if cycles are missing at the end of the runtime and (if applicable) block mode.
