General Safety Warnings
Personal Safety
■Everyone is responsible for safety.
■The installer/service personnel should be trained and authorized to complete the required work.
■Ensure that the machine is safely isolated during installation and testing to protect all personnel.
■Complete all required risk assessments and job safety analysis (JSA) before commencing work.
■Observe all site specific and machine OEM procedures regarding the following:
– working at heights
– working in heat
– working in confined spaces
– all other site specific occupational health and safety (OH&S) procedures
Machine
■Carry out all prestart operations as per site and machine OEM procedures.
■Ensure the machine is safely isolated during installation and testing to protect the machine and other
equipment in the area.
■Do not operate any machine with a known fault and report all findings to the supervisor in writing.
■Test and operate machine as per machine OEM and site procedures.
■Read and understand machine and site specific operational and testing instructions.
Product
Before applying power to the equipment, the user/repairer/ installer must read all product instructions. If in
doubt, seek assistance.
■Ensure electrical connections are made as per RCT’s recommendations. Test circuits prior to connecting
power to any component.
■The equipment contains no user serviceable parts inside. Return the unit to RCT for repairs.
■Retain product and installation instructions for future use.
■Ensure that RCT’s recommended service procedures are included in the machine’s service routine.
■Observe all machine, site and RCT product warnings.
■Follow all machine, site and RCT product operating procedures at all time.
The application of safety should not be limited to the above recommendations.

Product Overview
The Muirhead®Idle Timer Controller, part number 11450, is designed to ensure a machine is ‘idled down’ for
the correct period of time as recommended by the original equipment manufacturer (OEM). This idle down
period allows the machine to cool slowly and prevent engine damage from heat stress. A prime example of
this is the engine’s turbochargers that require oil for bearing lubrication—the high temperatures of the
turbochargers must be dissipated before the engine is switched off.
Features and Functions
■Multi-voltage 12-24 V
■Selectable idle time cycle provides flexibility in shutdown time from 1 - 12 minutes, in one minute
increments
■Suitable for Energised To Run (ETR) systems
■Steering accumulator bleed down output
■Park brake applied detection
■Ground level machine shutdown
■Universal application
■Visual warning
■Integrated mount
■Environmentally sealed - IP65
■Simple and easy to use
■Customised idle timers are available with additional features such as lights and auxiliary shutoff on request.

Operation and Use
The Muirhead®Idle Timer Controller, part number 11450, operates (by default) by shutting down the machine
after a three-minute time delay when the ignition is switched off. The operation of the controller is detailed
below;
1. Turn the ignition switch off.
−The machine will continue to run for the pre-programmed time cycle with the cycle LED (usually
mounted in the instrument panel) illuminated. Once the timed cycle has been completed, the machine
will shut down.
−If the ignition is switched back to run at any time within the timed cycle, the timer will reset and
commence the full cycle, once the ignition is switched back to off position.
2. Activating the engine shutdown switch while the unit is in idle down mode will cause the machine to shut
down immediately. This will only occur with the ignition in the off position.
Note
If the ground level shutdown feature is active, then the engine shutdown switch will shut down the machine
when the key is in the on or off position.
Park Brake Applied Detection (Optional)
If this option is used, the park brake switch must be connected to the controller.
1. When the key is switched to the off position and the park brake is applied, the controller will enter idle
down mode. If the park brake is released while in idle down mode, the alarm will sound and the machine
will shut down instantly, preventing an operator driving off with the key in the off position.
2. If the key is switched off at any time with the park brake released, the machine will shut down immediately
and the alarm will sound.
3. If an operator is required to mobilise the machine whilst the key is switched to the off position and the
machine is in idle down mode, the key must be returned to the run position before the park brake is
released.
Ground Level Shutdown (Optional)
If this option is used, it allows additional ground level shutdown switches to be installed in series with the
standard engine shutdown switch. It also allows the machine to be shut down at any time whether it is in idle
down mode or not.
These switches allow for shutdown of the machine when not in idle down mode (key ON).
To activate this option, pin 7 must be connected to machine ground.
Warning
This product has been designed to shut down the engine while at idle only. If the engine RPM is high, there is
a possibility of the control unit not being able to force a shutdown.

■All indicators will turn off.
■After power-up, the controller will revert to normal operation.
Status Indicator in Operation
RED – Fault.
■If outputs have problems, this will turn on.
■Outputs 1 & 2 – high current outputs: checked for overcurrent.
■Output 3 – not checked as it is a low side driver.
■Output 4 – checked for correct output voltage.
■Temperature – checked for board temperature exceeding 80 °C.
YELLOW – Pulses during normal operation, indicates system OK.

Installation Guide
1. Install the controller in a suitable location preferably in the cabin.
2. Refer to the wiring table below and the wiring diagram in this manual to connect the 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.
3. Mount the LED in a suitable location that is visible to the operator. Install the engine shutdown switch in
an area that is easily accessible to the operator.
4. Disconnect the existing ignition (OEM) wires from the ignition terminal at the key switch and connect the
orange wire (pin 5) to the ignition terminal.
5. Connect the yellow/blue wire (pin 3) to the (OEM) ignition wires previously disconnected from the ignition
terminal at the key switch.
6. If you are installing the device on machines using the C terminal at the key switch for auxiliary control after
shutdown, e.g., Caterpillar, disconnect the existing (OEM) wire no. 326 from the C terminal at the key
switch and connect to the purple wire (pin 9) from the controller

Setting No.
Description
Units*
Default
1
Idle time
The time the unit will keep the engine running when the
key is turned off, adjustable between 1 and 12 minutes.
minutes 3
2** Alarm output
Can be configured to be continuous or pulsed. Pulsed
3** Park brake input

Standard
(positive when
released)
*Note
The units’ column indicates the value that setting will increase by with each increment.
**Note
These parameters can be changed through programming; however, this will require the use of the
programmable controller utility available from RCT
Calibration Mode
Read the entire procedure before starting.
To enter calibration mode:
1. Hold the engine shutdown switch in the active position.
2. Turn on ignition.
3. Turn off ignition.
4. Release the engine shutdown switch.
5. The cycle LED will be flashing.
If performed correctly, the device will now be in calibration mode. This is indicated by all device status indicators
flashing very fast.
Note
The calibration mode will time out and exit if there is no user input for 60 seconds.
To exit calibration mode:
1. Cycle the power to the device (e.g., remove the Deutsch plug from the device and then reinsert it).
Changing Idle Time Value
1. Enter calibration mode;
2. Toggle the engine shutdown switch (i.e., turn it on and then off again) to increment the idle time value by
one minute to a maximum of 12 minutes.
3. To save the new value, hold the engine shutdown switch on again and it must remain on for more than 10
seconds (this does not count as a toggle).
