Shutdown and decommissioning
7.1
Temporary decommissioning
To uphold any possible warranty claims, during
temporary decommissioning the operator must take
preservation measures to protect the EM-530/660
(versions SCR and SCR-ready).
7.1.1 Decommissioning for up to 6 months
In the case of decommissioning for up to 6 months, the
following preservation measures are required:
●
Check the corrosion/antifreeze concentration and
adjust if necessary to -20 °C.
●
Check the coolant pressure and adjust if necessary
to 1.3 bar.
●
Replace the engine oil with the same amount of
fresh oil and change the filters.
●
Crank the engine over several times with the help of
the starter.
●
Remove the spark plugs, preserve the cylinder
combustion chambers with interior engine
preservation spray, then replace the spark plugs.
●
Seal the intake apertures on the air filter box as well
as all supply air and extract air apertures.
●
Seal the exhaust pipes and the condensate drain
pipe.
●
Shut off the gas supply at the ball valve on the gas
train.
7.1.2 Decommissioning for longer than
6 months
If decommissioning the EM-530/660 (versions SCR
and SCR-ready) or disconnecting it completely from
the building structure, the following additional steps
must be taken:
●
Print out the controller internal data.
●
Remove the internal starter batteries and store them
in a suitable location, connected to a charger with
battery maintenance function.
PLEASE NOTE
Removal/transport of batteries!
Danger of short circuit/electric
shock
Danger of chemical burns from acid
► Fit the battery terminal cover.
► Transport batteries in an upright
position.
PLEASE NOTE
Battery storage!
Risk of freezing
► Protect batteries from direct
sunlight.
► Keep batteries free from the risk of
frost.
► If they remain in the system,
disconnect the negative terminal.
●
Ensure that the plant room is kept free from frost
and draughts during the shutdown.
●
Subject to the on-site installation conditions, it may
be necessary to cover the machine completely.
However, the cover must be easy to remove for
intermittent inspections.
●
Drain the oil reservoir and dispose of the oil. If the
date for shutting down the system is known well
enough in advance, it is possible to limit the amount
of oil in the reservoir in such a way that the oil level
is virtually zero by the time of shutdown.
Measures to be taken during the shutdown period:
●
Perform a visual inspection for leaks every
6 months.
●
In addition, crank the engine over several times with
the help of the starter. For this purpose, install the
starter batteries and remove the seals from the
appropriate apertures beforehand. Following the
preservation of the cylinder combustion chambers,
return the unit to its original condition.
●
Permanent and faultless functionality cannot be
guaranteed by the preservation measures.
●
If the machine is to be used again, carry out a
complete commissioning procedure. This applies in
particular if the CHP unit has been disconnected
from the building structure and/or extensive
alterations have been made to the peripheral
equipment. Several hours of supervised test
operation are also recommended.
