Temporary Shutdown - salmson Rocsan EVO Serie Instalacion Y Puesta En Servicio

English
LETHAL explosion hazard
If the shut-off valves on the intake and discharge
side are closed during operation, the fluid in the
hydraulic housing will be heated up by the pumping
movement. Considerable pressure is created in the
hydraulic housing by the heating. The pressure can
cause the unit to explode! Before switching on the
unit, ensure that all the valves are open.
• The hydraulic housing must be flooded, i.e. it should be
completely full of fluid, with no air in it at all. Bleeding can
be carried out using a suitable bleeding device in the sys-
tem, or, if available, with bleeder screws on the discharge
port.
• Check that all accessories, the pipe system and suspension
unit are properly fitted
• Check all level control and dry-run protection systems
6.5.2. After starting up
The rated current is briefly exceeded during the start-up proce-
dure. Once the start-up procedure has completed, the operating
current may no longer exceed the rated current.
If the motor does not start immediately after the unit is switched
on, it must be switched off without delay. The start pauses spec-
ified in the "Technical data" section must be adhered to before
starting up again. If the fault recurs, the unit must be switched off
again immediately. The unit may only be restarted, once the fault
has been rectified.
6.6. Safety rules during operation
When operating the product, always follow the locally applicable
laws and regulations for work safety, accident prevention and
handling electrical machinery. To help to ensure safe working
practice, the responsibilities of employees should be clearly set
out by the owner. All personnel are responsible for ensuring that
regulations are observed.
The product has moving parts. During operation, these parts turn
to pump the fluid. Certain materials in the pumped fluid can cause
very sharp edges to form on the moving parts.
BEWARE of rotating parts!
The rotating parts can crush and sever limbs. never
reach into the hydraulics or the moving parts
during operation.
• Before performing maintenance or repairs, switch
off the product, disconnect it from the mains and
secure it against being switched on again without
authorization.
• Let the moving parts come to a stop!
The following must be checked at regular intervals:
• Operating voltage (permissible deviation +/-5% of the
rated voltage)
• Frequency (permissible deviation +/-2% of the rated
frequency)
• Current consumption (permissible deviation between
phases is a maximum of 5%)
• Voltage difference between the individual phases (max.
1%)
• Starts and stops per hour (see technical data)
• Air entry in the intake, a deflector plate should be fitted
if necessary
• Minimum water immersion level, level control unit, dry-
run protection
• Smooth running
• Shut-off valves in the intake and discharge pipes must
be open.

7. Shutdown/disposal
• All work must be carried out with the greatest care.
• Proper protective clothing must be worn.
• When carrying out work in basins or containers, the local
protection measures must be observed in all cases. A sec-
ond person must be present for safety reasons.
• Only hoisting gear that is in a technically perfect condition
and load-carrying equipment that has been officially ap-
proved may be used for lowering and raising the product.
RISk of fatal injury due to malfunctions!
Load-carrying and lifting equipment must be
in a perfect technical condition. Work may only
commence if the auxiliary hoisting gear has been
checked and found to be in perfect working order.
If it is not inspected, fatal injuries may result.
7.1.

Temporary shutdown

For this type of shutdown, the product remains installed and is not
cut off from the electricity supply. For temporary shutdown, the
product must remain completely submerged so that it is protected
from frost and ice. Ensure that the temperature of the pumped
liquid and in the operating area does not fall below +3 °C.
This ensures that the product will be ready for operation at all
times. For longer standstills, a regular (monthly to quarterly) func-
tion test should be carried out for a period of 5 minutes.
CAUTION!
only carry out a function run under the proper
operating and usage conditions. never run the ma-
chine dry! This can result in irreparable damage!
7.2. Final shutdown for maintenance work or storage
The system must be switched off and the product must be dis-
connected from the mains by an electrician and secured against
being switched on again without permission. Units with plugs
must be unplugged (do not pull the cable). Work on removing the
product, maintenance and storage can then commence.
