CARRIAGE TRAVEL SWITCH:
Provides
FORWARD/STOP/REVERSE

DIGITAL READOUT:
The display is dual function.
a) PRESET SPEED -
Displayed when the
CARRIAGE TRAVEL SWITCH
is
OFF
or motion is halted by a motor overload condition.
b) MEASURED SPEED -
Displayed when power is applied to the motor. (This will
be the same as the Preset Speed.)
Factory settings of 120 Volt machines are set to in/min, 240 and 42 Volt machines are set cm/min.
WELD CONTACT:
Opens/closes a pair of independent 1 Amp contacts (pins A & B and C & D) at the
weld contactor receptacle. In STITCH mode, this switch acts as a weld contact en
-
able and the stitch module cycles the contacts on and off.
NOTE:
A safety interlock will automatically open the weld contacts if the motor overload protection halts
machine motion. Clear the overload by turning the carriage travel switch to
OFF
. Resetting the
overload fault will not cause the contacts to automatically reclose. Use the weld contact switch to
restart the welder after clearing the overload.
