FILM LOADING (CONT’D)
WARNING! Always ensure that the machine is in stop mode before attempting to thread the film carriage.
Inadvertent movement of the dancer bar will cause the rollers to turn abruptly, creating the possibility of
serious injury. The operator must respect the film loading and threading instructions AT ALL TIMES!
If the film web breaks during the cycle, reattach the film, or if necessary, rethread the film following the
instructions. It is not necessary to reinitiate the machine. If E-stop is activated, the pre-stretch and the
clamp will not work. If the E-Stop is pressed, pull it and press rearm to rearm the M.C.R., then, press ACK
Alarm to clear the alarm.
The machines equipped with a standard carriage are programmed to stop when a lack of film occurs. In a
wrap cycle during which the rotation is active and the pre-stretch motor stops working for more than three
(3) seconds, the machine will return to home position then go in stop state. The cause is a stop, a lack of
film or a film break. Follow the film threading procedure (previous pages) to rethread the film to start/restart
a cycle.
The machines are equipped with a proximity sensor used to determine if the carriage
gate is closed properly. This sensor can be seen through the hole in the carriage
cover. When the light is lit, it indicates that the carriage door is closed properly. If the
gate is open, the pre-stretch motor will stop working or if the machine is running a
wrapping cycle, it will stop by itself rapidly. If the light is not lit, make sure the gate is
properly closed. The machine is ready for a start cycle.
Please note that the use of the override leads to a temporary loss of safety. Make sure no one accesses
the wrapping zone when the override is in function.
