ORDERING INFORMATION
COIL WINDING MACHINE CONTROL W/REMOTE PRINTING
This application depicts a GEMINI 2000 controlling a coil winding machine.
A length sensor provides output units in feet. Output 1 is used as the slow-down
for the drive motor and Output 2 is used for the cut off knife control. A printer is
used to record the length of each coil that is wound. Preset 1 is set to the slow
down length and Preset 2 is set to the desired length of the coil.
TYPICAL COUNTER APPLICATIONS (Cont’d) TYPICAL RATE INDICATOR APPLICATION
RATE INDICATION WITH SPEED LIMITING
In this application, a GEMINI 1000 is used to indicate the speed of a
printing press operation in feet/minute, while limiting the maximum speed
to a desirable level.
A magnetic pickup is used to sense a gear coupled to a feed roll on the
system drive. The scale factor on the GEMINI 1000 is set to provide a direct
readout in feet/minute with a one-second sample time.
The maximum allowable speed of the operation is entered as the preset
value on the rate indicator. The output termination is programmed for the
“boundary” mode in which the output remains “OFF” as long as the speed
of the operation stays below the preset level. If the operational speed equals
or exceeds the maximum allowable limit, the output will turn “ON” and
remain “ON” until the speed is reduced below the preset value.
The output of the GEMINI 1000 is tied to the speed control circuitry of
the system drive and triggers the necessary speed reduction if the maximum
allowable rate is exceeded. The jumper between the “Program Disable” and
“Common” terminals is used to prevent any accidental or unauthorized
programming changes. Connecting the jumper after the unit set-up is
complete will allow full interrogation of front panel functions, although any
function alteration will be inhibited.
