General maintenance recommendations

Make daily checks of system
Before operating the system each day, a general check of the system is highly recommended. Performing
a good general check on a daily basis is an important part of preventative maintenance. It also allows the
operator to become familiar with the system, and with what is considered normal behavior and normal
appearance. Once familiar with the system, operators will be more likely to notice any abnormalities that
could indicate problems, or potential problems, with the system. Before operating the system each day:
•
Check that the frame is square and not out of alignment. This can be a simple visual check. Stand
away from the frame and check that all horizontal components (i.e. the base, guide plate and
crosshead) are parallel with each other and aligned vertically. Also check that all vertical
components (i.e. the columns and, for frames with a J3-style crosshead, the lift cylinders) are parallel
with each other and aligned horizontally. Misalignment indicates that a larger problem exists.
•
Check that all testing fixtures (compression plates, bend fixtures, external tension accessories,
adapters, etc.) are free of dirt, damage and deformation. Any fixture with damage or deformation
should be corrected before use!
•
Check that power is adequately supplied to the electronics. Start up the system and check all
indicator lights on the user control panel, HPS controls and 59 Series control unit. Check that the
lights are not too bright or too dim, and that they don’t flicker. If any of these conditions exist, this
could indicate a problem with the power supply in the 59 Series control unit or with system main
power (customer supply).
•
Visually inspect the following for signs of oil leakage. Investigate any leakage and correct
appropriately. It is not necessary to remove any covers from equipment unless an oil leak is found.
• Any exposed hydraulic hoses - this may indicate leakage from loose connections or from
damaged hoses.
• Around the crosshead and hydraulic cylinder - this may indicate leakage from loose hydraulic
connections at the hydraulic cylinder or from the hydraulic cylinder itself. After several years of
use, it is normal to see some weeping or seeping of oil from the hydraulic cylinder. This small
amount of oil can be cleaned and normal operation of the frame can continue. Excessive
leakage that results in pooling of oil over a short period of time is abnormal, see
“Inspect the
hydraulic cylinder” on page 55 for guidance.
• Around the base of the HPS - this may indicate leakage from internal hydraulic connections.
Remove covers as necessary to investigate any oil leakage; see
“Remove and install console
covers” on page 54 . If an oil leak is suspected from the hydraulic cylinder, see “Inspect the
hydraulic cylinder” on page 55 for guidance.
•
Check that all cables are free of wear and chafing, have adequate slack to prevent excessive strain
on connectors, and have tight connections.
If any of these checks reveal a potential problem, the problem should be investigated and corrected
before the system is operated. For assistance in troubleshooting the system, contact your local Instron
Services department as directed on page
18 .
