Installation

TURBO TIMER INSTALLATION

These instructions are for 925 Series turbo timers. They are also generally applicable to the 724 Series and 725 Series turbo timers. These do not have a green (parking brake interface wire) and references to the green wire in these installation instructions should be ignored.

IMPORTANT INFORMATION

Disconnect the vehicle battery before commencing installation of the turbo timer.

The turbo timer black wire must be connected to an effective vehicle earth.

The turbo timer green wire must be connected to the vehicle parking brake wire or earthed directly for the timer to operate.

If the vehicle has electric radiator fans (mainly petrol engines) ensure that they can operate during the idle period if required.

Operating Voltage: 10 - 28 Volts DC

Maximum Current Drain (per circuit): 10 Amps

If the maximum current drain cannot be determined (wire-in turbo timers) install an external relay as per the included instruction sheet.

Reverse polarity protection is provided.

MOUNTING THE TURBO TIMER

Select a suitable position to mount the turbo timer control unit on the vehicle dashboard. This should be within easy reach of the driver/operator.

Avoid the possibility of the timer indicator light reflecting into the windscreen during night driving.

Allow for running the flat cable between the timer control unit and timer module. In some cases a 10 mm diameter hole may be required to pass the cable through the dashboard panel.

Before mounting the control unit with the double sided tape provided, ensure that both surfaces are cleaned with a silicone release solvent. The double sided tape is a high strength type which is capable of withstanding the very high temperatures that may be encountered in a parked vehicle.

The timer main module can be mounted in a convenient location behind the dashboard.

Connecting the Turbo Timer - Plug-In Styles

These turbo timers simply plug in to the existing connectors which link the ignition switch to the vehicle wiring.

These connectors will be located in one of the following locations:

  • On the back of the ignition switch itself.
  • In-line near the ignition switch.
  • On a connector mounting bracket.
  • On the back of the fuse panel.

If in doubt about the positioning of these connectors, start at the back of the ignition switch and follow the wiring loom until they are located. Check the switch itself for a built-in connector.

Once they have been located, unplug the vehicle connectors and plug the turbo timer male and female connectors into position.

Connect the turbo timer green wire to the vehicle parking brake wire. If this feature is not required, connect the green wire to negative.

Ensure good earthing of the timer black wire.

HIGH CURRENT DRAIN INSTALLATIONS

Current loads exceeding 10 Amps may damage timer relays.
Employing an external relay to carry these loads not only isolates the timer from the load itself, but also from the voltage spikes often associated with high current switching.
Use only a good quality, spike protected relay.
For 925/ST-2 and 925/ST-5 timers, the yellow wire can remain connected in parallel to a low current circuit.

X SERIES IDLE TIMER INSTALLATION

These instructions are for the X Series idle timers. Refer to separate installation instructions for 925 Series turbo timers.

IMPORTANT INFORMATION

Disconnect the vehicle battery before commencing installation of the idle timer.
The idle timer black wire must be connected to an effective vehicle earth.
The idle timer green wire must be connected to the machine parking brake or an effective earth.
Ensure that the load on any one timer output does not exceed 10 amps.
The idle timer will not operate until the engine has been running for at least 30 seconds.
Operating Voltage:    12 - 32 Volts DC
Maximum Current Drain (per circuit):    10 Amps
Selectable Idle Periods:    30 Seconds to 30 Minutes
Reverse polarity protection is provided.

MOUNTING THE TURBO TIMER

Select a position to mount the timer STOP switch.
The idle timer stop switch is waterproof and may be mounted in an exposed position.
The switch may be panel mounted using a 16 mm hole or it can be mounted on the bracket supplied.
The stop switch nameplate is self adhesive.
The timer module can be mounted in a convenient location behind the control panel.

SELECTING AN IDLE PERIOD

Remove the 4 screws to open the idle timer case. To select an idle period the blue rotary switch on the PCB is adjusted with a small screwdriver.

The idle times are as follows:
0 = 0.5 min
1 = 1 min
2 = 2 min
3 = 3 min
4 = 4 min
5 = 5 min
6 = 10 min
7 = 15 min
8 = 20 min
9 = 30 min

The default idle period is 3 minutes.

IDLE TIMER PARK BRAKE CONNECTION

Wheeled machines must employ the idle timer parking brake connection feature.
The timer green wire connects to the park brake as shown in the diagram below.
This allows the timer to work only if the park brake is applied. If the park brake is released during the idle period the timer will cancel immediately and the engine will stop.



For machines that do not employ a park brake, connect the green wire directly to negative (earth). This will allow normal timer operation.

HIGH CURRENT DRAIN INSTALLATIONS

INFORMATION AND FEATURES

The turbo timer will not operate until the engine has been running for at least 30 seconds. This prevents unwanted timer operation if the engine is started accidentally.

Vehicle Remote Central Locking

With most modern vehicles, the remote central locking is disabled whenever the engine is running. This only applies to the remote itself (on the ignition key or key ring). This is to prevent unwanted flashing of indicators or sounding of the horn while driving.

When a turbo timer is installed to provide an engine idle period, the remote central locking may be disabled until the end of the idle period. The vehicle may still be locked using the ignition key at the driver's door, accessing the central locking.

However, where the law requires, the vehicle driver must remain with the vehicle until completion of the idle period.

Locking In An Idle Period

A preferred idle period may be locked in place, preventing the operator from changing this time selection.

To Lock In:
Turn ignition ON.
Select the preferred idle period using the MIN. button.
Press & hold the STOP button until all 6 LED's flash briefly (after approximately 10 seconds).
Turn ignition OFF.
This default idle period will remain even if the vehicle battery is disconnected.

To Unlock:
Turn ignition ON.
Press & hold the MIN. button until all 6 LED's flash briefly (after approximately 10 seconds).
Turn ignition OFF.
The idle period is now released.

Park Brake Connection

Turbo Timer Parking Brake Diagram

This is not applicable to CTR-M5 model timers.

The timer green wire connects to the vehicle park brake as shown on the diagram below. This allows the timer to operate only if the park brake is applied. If the park brake is released during the idle period, the timer will cancel immediately & the engine will stop.

Connecting the green wire directly to negative (ground) will by-pass this feature & allow the timer to operate regardless of the park brake position.
