BASIC REMOTE CONTROL FOR START AND EMERGENCY RETRACT FUNCTIONS

M104

32

Remote start is accomplished by introducing a momentary pres- sure signal to port “B”,using fitting, valve and signal quality tubing as shown. The pressure signal should be about one (1) second in duration, this is sufficient for most applications. NOTE: For very low spindle speeds with medium to fine pitch lead screw, the sig- nal duration may need to be increased beyond one second. For very high spindle speeds and short stroke settings, the signal duration may need to be decreased and positively controlled - consult factory in this case.

Remove retract: Even though the tapper automatically retracts at a preset stroke, it may be desirable to connect an “Emergency Retract” function. This will allow the operator to retract the tapper during operation if it should become necessary. Remote emer- gency retract is accomplished by introducing a momentary pres- = sure signal to port “E”,using fitting, valve and signal quality tubing - as shown. The pressure signal should be about one (1) second in duration, this is sufficient for most applications. The remote retract signal should be terminated by releasing the 3-way valve once the tool is retracting.

The start valve should be a 3-way type valve capable of proper response.

The retract valve should be a 3-way type valve capable of proper response.
