is not necessary to adjust the SG 631 LOGIC to a mains frequency
of 50 Hz or 60 Hz as the machine uses motors and the power
supply unit is designed for operation with either frequency.
Note:
Extreme overloading of the power supply unit or internal short-circuiting
activates an automatic guard circuit that switches off the power supply
unit. Disengaging then re-engaging the POWER push-button returns the
guard circuit to its "alert" function. Fuses for the D.C. voltages in the
machine may also burn out when the guard circuit is activated. Such
fuses should be replaced only by a service technician as the cause of
the blow-out must be detected and, if necessary, removed.
1.5 Mounting Feet for Upright Operation
For upright operation, two feet "D" are provided with each machine
(see Fig. 1). To mount them, first lay the machine on one side. Turn
fixing screws "E" a few times into the threadings "F". Next push notches
"G" in the feet "D" under the head of the fixing screws "E" until the
bridge catches in groove " I " . Then tighten fixing screws "E".
