12.3.3 Heated Breather Installation
The heated breather canister is controlled via a thermostatic switch and
requires fused connection to the machine battery. The breather is both 12
and 24V compatible however the wiring to the breather is voltage dependant
as shown below in figure 12.9. The current consumption of the unit is also
dependent upon supply voltage with 24V being 2A and 12V 4A.
Figure 12.9 12 + 24V Wiring Solution
The Connector used to supply battery voltage to the breather heater is a 4
way connector. Part number details are shown in table 12.5.

12.4 Cold Weather Regeneration Aid
12.4.1 Cold Weather Regeneration Aid Operation
For 1204F and 1206F DOC, DPF & SCR applications, wishing to operate at
low idle for long periods of time at an ambient below –18°C a regeneration aid
is required. This regeneration aid is designed to allow the engine to passively
regenerate when required by elevating the engine speed from its current low
idle position to a fixed speed of 1200rpm. The engine will only take control of
engine speed if the associated wiring is completed and the engine determines
that a regeneration is required.
Increasing engine speed to 1200rpm allows the engine control strategy to
maintain the engine exhaust temperatures required to activate passive
regeneration of the engine DPF. This feature is available for all Tier 4F
products and requires no Specific configuration.
