Model 78 Mite-E-Mark Operation Guide and Parts List

Product catalog summary
Installation
  • Mounting: The Model 78 can be mounted using either rear or foot mounting options, requiring four 10-32 screws. It should be placed on a sturdy, level platform with the stamp face positioned 0.8 to 0.9 inches from the part to be marked.
  • Air Requirements: The device is air-powered, requiring a minimum 3/8" shop airline. Operating pressure should be between 20 psi and 100 psi. The airline length between the valve and marker should not exceed 3 feet. The marker has 1/4” NPT advance and 1/8” NPT retracting air ports.
  • Adjustments: Marking depth is controlled by air pressure adjustments via a regulator on the FRL unit, which is sold separately.
Maintenance
  • Safety: Ensure all air and electrical power is shut off before maintenance.
  • Lubrication: Use 10W "light" industrial hydraulic oil in the lubricator bowl, adjusting flow to one drop per 30-50 cycles. The Model 78XX-XX-XX-X-NL does not require lubrication.
  • Air Filter: Regularly check and clean or change the air filter based on environmental conditions. Avoid excess water in the filter bowl.
Pneumatic Controls
  • Double Solenoid Valve: Energize solenoid "A" to advance the marker. To reset, de-energize "A" and energize "B".
  • Spring Return Valve: Energize solenoid "A" to advance, and de-energize to reset after marking.
  • Speed Control: Adjust "R" to control retract speed. Do not install speed control on the forward port.
  • Note: For efficient operation, the electrical signal to solenoid "A" should be brief, approximately 0.06 to 0.10 seconds.
Parts Lists
  • Separate parts lists are provided for Model 78 with 1” and 2” strokes, and Model 78G with 1” stroke.

Model 78 Mite-E-Mark Operation Guide and Parts List-1

Installation Mounting: For rear mounting the model 78 has (4) tapped holes, and for foot mounting the 78 has (4) through holes both of which require (4) 10-32 screws to mount marker into position. The model 78 markers require a sturdy, level platform for mounting. For optimum power, the marker should be mounted so that the stamp face is .8 to .9 inches away from the part to be marked. Pneumatic Controls Electrical Sequence for Double Solenoid Valve: To advance marker, energize solenoid "A". To return marker and reset, de-energize solenoid "A" and ENERGIZE solenoid "B". Air Requirements: Model 78 is air powered for both forward and return stroke. CMT recommends 3/8" 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 1/4Ҕ NPT advance and 1/8 NPT retracting air ports. Electrical Sequence for Spring Return Valve: To advance marker, energize solenoid "A". To return marker and reset, de-energize solenoid "A" after part is marked. Speed Control Adjustment: DO NOT install speed control on forward (rod) port of marker. Adjust speed control "R" to control speed of retract motion. Adjustments: Increased air pressure marks deeper, and decreased air pressure marks lighter. To regulate marking pressure adjust regulator on FRL (Filter/Regulator/Lubricator combo unit). Sold separately. Note: For most efficient operation, electrical signal energizing solenoid "A" should be very short, approximately .06 to .10 seconds. Maintenance Suggested Pneumatic Control Diagram Shut off all air and electrical power prior to performing any and all maintenance. > Marker Sol ԓA Standard 4-Way Valve 3/8Ԕ Shop Air FRL Combo Unit Sol BӔ 3/8 Tube ԓR3/8Ԕ Tube Lubrication: Add 10W "light" industrial hydraulic oil to lubricator bowl and adjust oil flow to approximately 1 drop for every 30-50 cycles. The Model 78XX-XX-XX-X-NL is a non-lube system and does not require any lubrication. Air Filter: Check and clean /change as required. The frequency of cleaning/changing is dependent on environment and plant air system. Do not allow excess water to fill filter bowl. >
