MANUAL System overview – Stage V Pipe material Scania recommends that the exhaust pipe between the particulate filter unit and SCR unit be made from stainless metal type 1.4301 or 1.4509, US grade 316L or equiva- lent. Other instructions on exhaust system shape and fitting are available in 01:04 Exhaust system.
SCR catalytic converter. Dimensions The SCR unit is available in 2 versions. Engine L1 (mm) L2 (mm) DC09 and DC13 up to 331 kW 763.5 DC13 over 331 kW 840.5 The tolerance for dimension L1 is ±3 mm. 01:07 Issue 17 en-GB...

IMPORTANT! Maximum permitted ambient temperature at the reductant doser is 115°C. On the SCR unit, there is a drain hole for emptying flush water (1). Scania recom- mends that the SCR unit is positioned with the drain hole facing down.

The exhaust pipe between the evaporator or hydrolysis catalytic converter and the SCR catalytic converter must be made from stainless metal type 1.4301 or 1.4509, US grade 316L or equivalent. Scania also recommends that this material is used for Oxidation catalytic converter.

The tightening torques for the V-clamps in the SCR system are indicated in the illus- trations to the right. IMPORTANT! Scania recommends that the V-clamps in the SCR system are retightened after the engine has reached operating temperature for the first time. Carry out the retighten- ing when the engine has cooled down again.
Stage IV/Tier 4f: Evaporator for DC09 and DC13. DC16. Stage IIIB/Tier 4i 530.5 For engines certified according to Stage III B/Tier 4i, an evaporator is used for DC09 and DC13. For DC16, see Hydrolysis catalytic converter. The illustration shows the dimensions of the evaporator.
The reductant pump and EEC3 control unit are located on the reductant tank. The re- ductant tank is heated via the engine cooling system. 38 litres. Scania advises against manufacturing your own reductant tank. 60 litres. The reductant tank and reductant pick-up unit are designed to withstand freezing.
Malfunction Indicator in section DLN7 in 03:05 CAN interface. There are no specific requirements for how other warnings should be displayed. However, Scania recommends that the warning lamps described on the following pages are used. For all warnings, a fault code is generated via DM1 which describes in detail the component affected by the fault and the type of fault.
The system reacts to a low reductant level via the CAN message DLN8. For further information on connection, see 03:05 CAN interface. To indicate low reductant level, Scania recommends that the warning lamp according to ISO 7000 - 2946 is used in accordance with the strategy below.
The system reacts to faults in the exhaust gas aftertreatment system via the CAN message DLN8. For further information on connection, see 03:05 CAN interface. To indicate faults in the exhaust gas aftertreatment system, Scania recommends that the warning lamp according to ISO 7000 - 2596 is used in accordance with the strat- egy below.
To indicate that the particulate filter is full and needs to be regenerated manually, the CAN message DPFC1 is used. See 03:05 CAN interface. In order to indicate that the particulate filter needs to be regenerated manually, Scania recommends that the symbol for particulate filter regeneration according to ISO 7000 - 2433 is used.
They must be installed correctly in the vehicle or machine. The warn- ing lamps can be ordered via Scania and also accompany the Scania EMS display. If the installer uses neither Scania warning lamps nor the Scania EMS display, then the lamps used must have the same functionality and symbols.
Periodic hydrocarbon evaporation can be selected with two different settings: • Only warning. • Warning and engine shutdown. Scania recommends that this setting is used for unmanned applications. If the engine is started again after an engine shutdown due to accumulated hydrocar- bons, and is idling without load, the engine is switched off again after five minutes.
