A Guide to Safe Use of Mains Powered Test Frames

9. Machine guarding

If, after the risk assessment, it is considered that machine guarding is needed, then please
contact your local supplier who, through the Mecmesin Sales Department, can arrange the
supply of a suitable guard for the required level of protection.

10. Continued safe use

Once the machine is installed it should provide a reliable long term resource for universal
testing. If however the machine fails, or appears to behave in an unusual manner, contact your
local supplier for support. Do not continue to use the machine until it has been checked and if
necessary, repaired and returned to a safe working condition.

10.1 Servicing and calibration

To ensure optimal safe performance, your test stand must be regularly serviced and the
Intelligent Loadcell (ILC) or Intelligent Torque Cell (ITC) calibrated by Mecmesin Ltd or an
authorised distributor.

If the machine is damaged in use, advise your local supplier and have the machine repaired to
a safe working condition. Do not use the machine until it has been repaired.

11. Cleaning

It may occasionally become necessary to clean the outside of your test stand. This can be done
by disconnecting the mains electricity supply, removing loose debris with a soft brush, then
wiping with a damp cloth.

Note:

when cleaning the membrane keypad, care must be taken to avoid liquids, especially

alcohols, seeping around the edge of the membrane. Therefore, we recommend the use of a
lightly dampened cloth to avoid liquid spillage onto the membrane.

Under no circumstances

should organic solvents or any other cleaning fluid be used.

12. Moving/Re-installing the Machine

The test stand must be powered down before attaching/removing cables. When the connectors
are not in use please ensure that they are covered with the connector covers all the time.

Note:

no cable should exceed 3 metres in length.

Note:

it is advisable to remove the Console, if present, from the test stand before moving the

machine.
