2.1 LMC 301 controller unit

The SKF LMC 301 Controller is used to

control SKF Single Line centralized

lubrication systems.

Depending on the system design, up to

three independent lubrication zones can be

controlled.

The SKF LMC 301 controller handles control

and monitoring of the system. The current

system status is shown on the LMC 301

controller's display. The user can quickly

adapt the lubrication procedure by changing

the lubrication intensity

.

The SKF LMC 301 Controller offers the

following pump settings according to the

system design:

o Up to three lubricant pumps.

o Up to three lubrication zones (zones 1

to 3) per pump (main lines 1 to 3).

o Type of zone valves via 2/2 or

3/2 directional solenoid valves.

o Time- or pressure-based lubrication

monitoring.

17

2

EN


o Pump control and monitoring.

o Temperature monitoring by internal or

external sensor.

o Automatic filling.

The SKF LMC 301 controller offers configu-

rations for the following zone settings for

each zone:

o Cycle Control, control mode time-based

or counter-based.

o Cycle Control for "light" or "heavy"

machine requirement with according

selection of "Light" or "Heavy" lubrication.

o Lubrication settings, setting of lubrication

time or, with counter control, the number

of pulses delivered by the machine.

o Flow rate monitoring.

o Alarm outputs and defined fault

diagnostics.

Some system settings and timings can be

modified by the customer via the password

level pocal Admin.

The previous settings can also be reset

to the default settings via the menu item

Set Params to Default.

)See Figure 3 on page 20

The following descriptions applies to a Single

Line centralized lubrication system with two

zones (two main lines).

The two zones are relieved via a reversing

valve downstream of the pump unit.

Both main lines are switched via a 2/2

directional solenoid valve upstream of the

respective main line.

Prelubrication or relubrication distributors

can be used as the Single Line distributors.

Depending on the design, the changeover

signal is sent by a shared pressure switch

(PT) or a pressure switch assigned to one of

the zones.

The pressure switch(es) can be designed as

NO-contacts (close when pre-defined pres-

sure is reached) or NC contacts (open when

pre-defined pressure is reached).

The fill level is monitored by a fill level switch

in the pump reservoir.

It can be designed as a NO-contact or an NC

contact.

2.2 General design of a Single Line

centralized lubrication system

18

EN


Another system design involves using

3/2 directional solenoid valves instead of the

2/2 directional solenoid valves. In that case,

pressure is relieved via an additional relief

line (7).

This system design does not require an ad-

ditional relief valve.

2.2.1 System design

)See Figure 3 on page 20

Pressure is built up from the pump element

(1) via the mechanical pressure relief valve

(2) and the downstream main lubrication

line (3) to the solenoid valves of zone 1 (4)

and zone 2 (5), and from there to the down-

stream Single Line distributors (6).

The pump feeds lubricant via the mechanical

pressure relief valve (2) and the main line

(3) to both solenoid valves of zone 1 (4) and

zone 2 (5).

Depending on the programming, one of

the two solenoid valves is open, resulting

in pressure build-up of the lubricant in the

corresponding zone, while the other solenoid

valve is closed.

The lubrication proceeds as follows on a

Single Line centralized lubrication system

with prelubrication distributors:

The pump feeds lubricant to the respec-

tive zone (main line) until all prelubrication

distributors have dispensed their defined

quantity of lubricant to the respective lu-

brication lines. The pressure switch sends a

signal to the controller that the changeover

is finished. The controller then switches off

the pump and the mechanical pressure re-

lief valve (2), which leads to pressure relief in

the main line and the previously active zone

(main line).

The active solenoid valve (4 or 5) switches

to an open state once its holding time has

elapsed.

After pressure relief has been performed,

the zones (main lines) are prepared for an-

other lubricating cycle.

The lubrication proceeds as follows on a

Single Line centralized lubrication system

with relubrication distributors:

The pump feeds lubricant to the respective

zone (main line) until a predefined pressure

is reached. The pressure switch (PT) then

switches and sends a signal to the controller.

The controller switches off the pump and

19

2

EN


switches the pressure relief valve to relief,

resulting in pressure relief in the main line

and the previously active zone (main line).

This causes the relubrication distributors to

relieve pressure, and lubricant is delivered to

the respective lubrication lines.

The active solenoid valve (4 or 5) switches

to an open state once its holding time has

elapsed.

After pressure release has been performed,

the system is now prepared for another lu-

bricating cycle.

The pump fill level is monitored by a fill level

switch in the pump reservoir.

5.3 Electrical connection

5.3.1 General

The controller unit is supplied with

100 to 240 VAC voltage or optionally with

24 V DC voltage.

In both designs, the cables are introduced

through a cable fitting with a clamping

range of Ø 0.18 in to 0.39 in and terminal

blocks with tension springs (maximum con-

ductor cross-section 0,1 in, conductor strip-

ping length 0.59 in).

Refer toChapter 4, Technical Data, Chapter

3, for the electrical characteristics of the

controller unit.

The connections on the controller unit are

established according to the customer-

specific design of the lubrication system/

main lines. The system manufacturer is thus

liable for correct connection to the controller

unit.

EN

5. Assembly

NOTE

On the controller unit's electrical

connections, ensure that appropriate

measures prevent interference

between signals due to inductive,

capacitive, or electro-magnetic

couplings.

Shielded cables must be used in

places where electrical interference

fields can distort signal transmis-

sions despite separate laying of

cables.

The rules and empirical values for

"EMC-compliant" cabling must be

taken into consideration.

NOTE

Lubrication Monitor Controller

contains electronic components

that can be destroyed by accidental

electrostatic charge or discharge

(ESD). Use appropriate measures to

prevent interference between

signals due to different types of

couplings. due to ESD, hands and

any tools must be discharged on

a bare grounded position on the

installation site prior to performing

any work on the opened controller

unit. Conductors or components

within the device must not be

touched under any circumstances.

NOTE

An appropriate switch or circuit-breaker

(min. 10A) who protect all pole must be

included in the building installation and

shall be in close proximity to the equip-

ment within easy reach of the OPERATOR.

The disconnecting device shall be marked

as the device for the equipment.

6.2.10 Pump 1 timings

General

Up to three pumps can be connected

to the LMC 301 Controller; the maximum

number of zones (main lines) that the Con-

troller can control is limited to three. Up to

three main lines (zone 1 to zone 3) can be

programmed per pump.

These can be accessed in the Main menu

under:

Pump 1 Timings

Zone 1 Settings

Zone 2 Settings

(if 2nd line available)

Zone 3 Settings

(if 3rd line available)

Depending on the access level, the following

settings can be made:

See Pages 40/41, Fig. 22 and 42/43, Fig. 23

The following entries can be made here:

o

or

o

The two lubrication settings differ in terms

of the duration of work cycle time.

The cycle time consists of the pump cycle

time + interval time - see Figure 20.

A longer lubrication time is typically pro-

grammed for Heavy Cycle Set compared

with Normal Cycle Set.

)The following menu items are available: o Lube Load: Selection between Normal Cycle Set and Heavy Cycle Set. The two lubri-

cation settings differ in terms of the duration of cycle time. A longer lubrication time is

typically programmed for Heavy Cycle Set compared with Normal Cycle Set.

o Normal Cycle Time: Entry of the time unit for a normal lubrication process. The total

value to be entered consists of pump cycle time+holding time+interval time. The lubri-

cation time is the time required by the lubrication system to build up pressure in the

respective zone until all distributors in the zone have actuated or reversed. The interval

time is the time differential between the set cycle time and the required pump cycle time

+ holding time. The entry is in hours/minutes/seconds.

o Heavy Cycle Time: Entry of the time unit for a lubrication process with increased lubri-

cant demand. The heavy cycle time has the same structure as the normal cycle time. The

entry is in hours/minutes/seconds.

o Monitoring Time: Monitoring of lubrication time Pressure build-up must be completed

within the monitoring time (time slot).

o Holding time: After the end of the pump cycle time, the controller switches off the pump,

though pressure relief by the zone valves is delayed by the holding time. The entry is in

minutes and seconds.

6.3 Single Line system examples

Several examples of Single Line systems

with an LMC 301 Controller are listed below

and can be used as the basis for local ad-

mins to make their settings.

The individual examples are divided into

three sections.

Section 1 is a brief description of the struc-

ture of the Single Line centralized lubrica-

tion system shown.

Section 2 shows the structure of the

particular Single Line centralized lubrication

system (system design) with the associated

LMC 301 terminal diagram.

Section 3 shows the customer program-

ming of the LMC 301 Controller via its dis-

play and keyboard (see Chapter 6.2).

LMC301, electrical terminal diagram, Fig. 25

Design

The example applies to a Single Line

centralized lubrication system with two

zones (zone 1/zone 2 (line 1/line 2)).

It is composed of the main components

Single Line pump (1) with mechanical

pressure relief valve (2) and one pumpout-

let. A main line (3) connects the pump

outlet with the two 2/2 directional sole-

noid valves for zone 1 (4) and zone 2 (5).

A pressure switch PT (6) is mounted at the

end of the main line to monitor pressure.

Chapter 3 contains a general functional

description.
