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.
