Product Overview

Figure 1Programmable lubrication controller

The Muirhead®Programmable Lubrication Controller, part number 9252, is designed for flexibility and is used

to automate the grease injection system on a machine.

The programmable lubrication (lube) controller is capable of operating in many different modes to suit multiple

lubrication systems available on the market. In the standard pump solenoid valve pressure switch

arrangement, the system can be programmed so that the pump can act as a reciprocating pump where it

requires a pulse circuit or it can just switch a pump on. The system provides the option to use a pressure

switch. The pause and pump periods can be adjusted from 0.5 seconds to up to 24 hours. It can also be easily

configured to act as a swap version where it activates a lube cycle on one bank for a period, then swaps over

and operates a second bank with full pressure switch monitoring.

The system has many diagnostic capabilities and when connected to the custom software package, the

complete system can be monitored.

Features and Functions

■Pressure switch monitoring

■Pulse or continuous pump

■Adjustable pause and pump periods from 0.5 seconds to 24 hours

■Swap between banks

■Manual pump mode

■Grease low level indication

■Customised software

■Inbuilt diagnostics

■12 or 24 volt machines

■Suits various lubrication systems

■Fully software configurable to suit all machine types

■One panel to suit all machines on site

■Modular design

■Internal alarm

Operation and Use

The Muirhead®Programmable Lubrication Controller has been designed with flexibility in mind. The system is

capable of operating in many different modes which suit multiple lubrication systems.

Control Unit

The lube controller has been designed to be an in-cabin mounted device.

Note

The lube controller is not IP rated for external mount.

The lube controller incorporates a manual lube cycle button that activates a cycle if pushed, as well as an

internal audible alarm.

The lube controller has LED indication and inbuilt diagnostics to aid fault finding. It also incorporates options

for low level detection, an external manual lube button and also an external alarm circuit. All calibrations and

programming are performed using a user-friendly software program via a notebook computer.

The programs can be saved and later loaded into multiple units if required and can be calibrated to suit all

types and variations of machines.

The power supply requirements are 8 to 36 volts dc and therefore suits all 12 and 24 volts dc machines.

The information below describes the operation of every function of the programmable lube controller, including

the inputs, outputs, LED indicators, and software options.

Inputs

Pressure switch 1 input This input can be configured to sense a positive or a negative and can be

normally open or normally closed. The options are software adjustable. The

standard configuration is negative and normally open, only closing when

pressure is achieved.

Pressure switch 2 input This input can be configured to sense a positive or a negative and can be

normally open or normally closed. The options are software adjustable. The

standard configuration is negative and normally open, only closing when

pressure is achieved. This input is only used on systems that require two

pressure switch inputs.

Low grease level input This input can be configured to sense a positive or a negative and can be

normally open or normally closed. The options are software adjustable. The

standard configuration is negative and normally open, only closing when a low

level is detected. This input is optional, if level monitoring is not available, do

not use this input.

External lube cycle input This input can only sense a positive signal. However, it can be configured to

be normally open or normally closed. The options are software adjustable.

The standard configuration is normally open, closing when a lube cycle is

required. This input is optional and acts exactly the same as the cycle button

on the lube controller.

Cycle push button Pressing this button activates a lube cycle. It bypasses the pause period. It is

generally used by the operator if they think extra lube is required. An additional

feature of this push button is when the unit is in alarm mode pressing this

button will mute the alarm for 10 minutes.

Outputs

Pump output This connection is a positive switching FET output. Rated up to 8 A, this output

is used to operate the lube pump. The active time period for this output is

software configurable.

Pulse output This connection is a positive switching FET output. Rated up to 8 A, this output

is used to control a pulsing circuit to drive a reciprocating pump. Both the pulse

on and off periods for this output are software configurable. This output can

also act as a swap output for dual bank systems. The selection of the swap

circuit is software configurable.

Alarm output This connection is a positive switching FET output. Rated up to 2 A, this output

is used to activate a remote mount alarm or visual indicator. This circuit is

optional due to the fact that the lube controller has an internal audible alarm.

The alarm output is software configurable to be on continuous pulse failure

warnings and not to operate at all.

LED Indication

Power on This indicator illuminates green when the unit is switched on.

Pump This indicator illuminates green when the pump output is active.

Pulse This indicator illuminates green when the pulse output is active. For a lube

controller configured for a two lube bank system, the indicator indicates that

the swap solenoid is active.

Press 1 This indicator illuminates amber when pressure switch 1 is active. It displays

one pulse if the lube cycle failed to reach pressure within its lube period,

indicating a possible broken line. It displays two pulses if the lube pressure is

achieved too quickly, indicating a possible blocked line.

Press 2 This indicator illuminates amber when pressure switch 2 is active. It displays

one pulse if the lube cycle failed to reach pressure within its lube period,

indicating a possible broken line. It displays two pulses if the lube pressure is

achieved too quickly, Indicating a possible blocked line.

Level This indicator illuminates red and pulses whenever the low grease level is

detected.

Software Options

Lockout pump When enabled, the lubrication pump is locked out after an open failure.

Lube at power up When enabled, the lube cycle is activated as soon as power is applied.

Two lubes banks (swap) When enabled, the lube controller operates two lubrication banks by operating

as a swap circuit.

Pulse low grease alarm The low grease alarm can be set to either pulsed or continuous during a low

grease fault.

Pulse low grease output The low grease output can be set to either pulsing or continuous during a low

grease fault.

No pressure switch The lube controller can be set up to operate with no pressure switch inputs.

Therefore no fault conditions occur when set up this way.

No sonar alert The internal sonar alert can be disabled.

External manual lube When selected it allows the unit to accept an input from an external manual

lube switch.

Installation Guide

1. Install the lube controller in a suitable location away from moisture and dust, preferably in the cabin area

where the operator has access.

2. Refer to the wiring table below and the specific wiring diagrams (that suits the system being installed) in

this manual to connect the lube controller. It is recommended that the wiring is installed alongside the OEM

wiring ensuring that it is secured at regular intervals; this will provide protection from heat and abrasion,

and any other excess damage that may occur with extended vehicle operation. When securing the wiring

to the OEM wiring, ensure that the loom is away from moving vehicle parts which could lead to loom

damage.

The following table details the different pin and wiring connections available on the lube controller.
