Installation Mounting : Mounting holes are located in the mounting bracket, and the use of 5/16-18 socket head cap screws with lock washers is required. The Model 88 markers require a sturdy, level platform for mounting. For optimum power, the marker should be mounted so that the stamp face is 2 1/8Ô to 2 3/8 away from the part to be marked for a 2 Խ stroke model. ԃ Electrical Sequence for Spring Return Valve: To advance marker, energize solenoid AӔ. To return marker and reset, de-energize solenoid AӔ after part is marked. Spring in marker returns ram after pressure is exhausted. Air requirements: Model 88 is air powered for the forward motion, and the return motion is spring controlled. CMT recommends a 3/8Ô minimum shop airline. Maximum operating pressure of 100 psi, minimum operating pressure of 20 psi. Please note that the airline length between the valve and marker should not exceed 3. The marker has one 3/8Ҕ NPT air port. Note: For most efficient operation, electrical signal energizing solenoid ÓA should be very short, approximately .06 to .10 seconds. ԃ Adjustments: Suggested Pneumatic Control Diagram > Marker Sol AӔ Standard 3-Way Valve 1/2 Shop Air FRL Combo Unit 3/8Ԕ Tube Increase air pressure to mark deeper.
