preventing any movement of the crosshead or rotating platen. To re-set the E-stop button,
rotate it about 30 degrees clockwise.
2.4 Ventilation
To prevent overheating, ensure that all the air ventilation vents on the test system are not
obstructed. Where a console is fitted and if it is cooled by an internal fan, ensure the
console air vents are not obstructed.
Mecmesin test systems should only ever be installed in suitable
environmental conditions. The operating temperature and humidity should
be within the range given in the specification.
2.5 Electrical Supply and Earthing
Connecting a mains powered test frame to the wrong voltage supply will almost certainly
cause extensive damage to the equipment. Mecmesin test systems must only ever be
connected to a mains power installation that has a fully installed earthing system.
Connection of a mains powered test system to an electrical power outlet
without an earth connection is extremely dangerous and could lead to a risk
of electrocution. Consult your organisation’s qualified electrician if unsure.
The combined mains input socket and voltage selector can be found on the rear panel of
the test system (or on the right-hand side of twin-column force systems). Check that the
voltage selector is set correctly for your supply. The voltage that is selected is the one where
the arrows meet (the power inlet is inverted for some test systems):

Selector set to 220-240 V
The voltage selection can be changed by switching off the power and removing the power
lead. The fuse cartridge can now be withdrawn. Rotate the fuse carrier and re-fit it so the
desired voltage marking is the correct way up.
See section 5.1 ‘Replacing fuses’ for how to remove the fuse carrier and replace a fuse.
