Storing The Control Block - Bosch rexroth M1-16 Series Instruction Manual

6�2 Storing the control block
• The storage areas must be free from corrosive materials, vapors and gases.
Requirements
• To prevent damage to the seals, the operation of ozone-forming devices
(e.g. mercury-vapor lamps, copiers, printers, high voltage equipment, electric
motors, sources of electrical sparks or electrical discharge) is to be avoided
in storage areas.
• The storage areas must be dry and free from dust.
• Ideal storage temperature:
• Minimum storage temperature:
• Max. storage temperature:
• UV protection:
Avoid significant exposure to light (e.g. bright windows or direct
fluorescent lighting).
• Relative humidity (no condensation):
• Do not stack control blocks and store them protected against collisions.
• Do not store the control block on sensitive assembled parts, e.g. actuation
elements, sensors, solenoids, or valves.
• Do not remove protective covers and protective plugs.
▶ Check the professional storage of the control block on a monthly basis.
The maximum permissible storage time is two years.
After delivery By default, control blocks are protected against corrosion with priming
(single-coat lacquer) or with a galvanized coating at the factory.
Mineral oil in plugged valves provides internal corrosion protection. Non-painted
or coating surfaces on the control block not provided with a galvanized coating
(e.g. flange surfaces) are not protected against corrosion.
Delayed commissioning, long freight and storage times or a prolonged
decommissioning of Rexroth control blocks leads to rust formation. Take additional
corrosion protection measures to prevent this.
Warranty entitlement will be rendered void if the requirements and storage
conditions are not adhered to or after expiration of the maximum storage time.
Recommended procedure after longer storage times:
1� Check the entire control block for damage and corrosion prior to installation.
2� Perform a test run to check the control block for proper function and
leak-tightness.
3� External seals of control blocks that have been stored for longer than
12 months are to be checked for damage before installation and may need to
be replaced.
4� If the storage time of two years is exceeded, external seals must be replaced.
After expiration of the maximum storage time, we recommend having the
control block checked by your Bosch Rexroth service partner.
If you have any questions regarding repair and spare parts, contact your
responsible Bosch Rexroth service partner or the service department of the control
block manufacturer's plant, see Chapter 10.5 "Spare parts" on page 42.
