2. Resetting stall memory value
• Two methods are available to reset
the stall memory value as follows:
• An output on/off switch is used to re-
set the stall memory value.
• Stall memory reset input MC4 con-
tacts are used for reset.
In either case, the switch is normally
turned on when the reel is changed.
• When the initial setting "MC4 + OUT.
SW" at the "STALL RESET" screen is
selected (see page 9), the control
output is switched from "ON" to
"OFF" by the output on/off switch on
the panel at the time of changing the
material. The stall memory value will
be preset to the stall setting value.
• When MC4 is kept "on" for approximately 0.5 second or longer, the stall memory value is preset to the
stall setting value.
3. Connection
• To reset the stall memory externally, the MC4 contacts
are used.
• Use a micro signal switch commensurate with DC8V
4 mA as the input contact.
• If the stall memory reset input MC4 and MCC are
short-circuited, the stall output is always the same as
the stall setting value.
• If a signal interlocked with the reel shaft release signal
and shaft removal signal is connected to the MC4
contacts, the stall memory can be reset automatically
when changing the material.
4. Resetting stall memory only by MC4
• The system can be set so as to reset the stall memory value only by the MC4 contacts without using
the output on/off switch.
• Use the "STALL RST" screen within "SWITCH" on the initial setting screen or the engineer screen.
