8.0 OPERATION.
The ST2520 motorized drive system can be controlled by hand speed control
( fig. 1 #5 page 9) or the optional foot control (fig. 6 b page 10).
When both are installed, the hand speed control is always the master.
You always have to put the hand speed control in the zero position (centre click)
before you can use the foot control. This can be done while winding.
Any deviation of the speed control in clockwise direction will cause the film rewinder
to transport the film from left to right and vice versa.
When you select the speed control by hand of foot from left to right (and v.v.)
the film rewinder will always stop / standstill for a few seconds and will start to wind
into the last chosen direction.
The ST2520 is specially developed for use in archives and laboratories.
The variable speed is smooth and therefore taking good care for your material.
In the very low speed the operator can easily check perforations and damages
by hand without interfering the motor control system.
The ST2520 will stop automatically in case the film breaks of when reaching film end.
There is a buzzer warning signal with this automatic stop.
The warning signal can only be switched off when the hand speed control (fig.1 #5)
is in the zero / central position.
You have several wind modes available:
1. direct from film plate to film plate.
2. via guide roller left or right.
3. via both guide rollers. (fig. 11 page 17)
4. via guide roller left and sprocket for counter (fig. 12 page 17)
To get the best wind result we do advise the mode 3 and 4.
