The stand will respond to the appropriate stand
reverse/stop signal from an AFG/AFTI connected to the back of
the stand to reverse or stop the crosshead. Note that in manual
mode, a stand reverse signal will stop the crosshead
movement all the time the AFG signal is in the appropriate
state - it will not cause the crosshead to reverse direction.
Mechanical limit switches are provided that are activated if the
crosshead passes an optical limit switch which fails to stop the
crosshead. No crosshead movement is allowed whilst a
mechanical limit switch is activated.
The required power supply voltage (110-120V or 220-240V) is
indicated by the value in the black panel within the fuse
cartridge housing. Your local Mecmesin representative will
already have checked that the fuse cartridge has been installed
correctly for the supply voltage of your country. It is possible
to modify your MultiTest-d for operation in a country with a
different supply voltage by: turning off the power, removing
the fuse cartridge housing, removing the black fuse cartridge,
checking that both fuses are fitted, rotating the cartridge
through 180°, then reassembling and reinstalling. The new
voltage rating will now be displayed in the black panel.
There is an external control part at the rear of the
MultiTest-d. The MultiTest-d, can respond via the appropriate
Mecmesin cable, to signals from an AFG or AFTI. For further
information, please refer to the Gauge Operating Instructions.
