Power failure
The Multimat
®
Easy offers a power failure protection
feature that allows the currently running program to be
continued after a power failure of
less than 60 seconds
as soon as the power returns. You will see error message
F 14 (see “Error messages and troubleshooting” ).
Note: The firing result must be inspected closely even if
the firing program was only interrupted for a very short
time.
If the power failure lasts
more than 60 seconds , the
currently running program will be interrupted.
Note: If the firing chamber has to be opened during the
power outage, you may
carefully push the firing plat-
form down manually . This will damage neither the motor
nor the gear mechanism.
Do not reach into the firing chamber
– burn hazard!
