Preliminary Steps Before Installation
Before proceeding with the installation of the enclosed equipment, you should undertake the following preliminary steps.
1. Read and make sure you understand this entire installation manual.
2. Refer to the front cover, other line drawings and photos, then make a sketch of your installation to plan the location of the enclosed equipment
on the machine.
3. Please make sure the machine is in first-class condition. Before starting any installation, it is essential that the machine is thoroughly
inspected. Be sure all mechanical components and all collateral equipment are in first-class operating condition. Your inspection should
be done according to the machine manufacturer’s installation and maintenance instruction manual. If you have any doubts or questions
concerning the condition of the machine, contact the machine manufacturer for assistance.
Repair or replace all parts not operating
properly before proceeding.
Inspection and maintenance programs must be established and implemented to keep machines in first-class condition.
Safety programs must include thorough inspections of each machine on a weekly basis and records kept of these
inspections. Any part of the machine that is worn, damaged or is not operating properly must be replaced immediately or
repaired before the machine is used.
4. Verify that the machine is in first-class condition and operating properly; shut off all power to the machine. Padlock all electrical and pneumatic
energy in the off position and do not actuate the machine again until the installation of all package components has been completed. Lockout/
tagout energy isolation procedures must always be practiced and enforced.
General Overview
The adjustable stroke DAF-100 Detect-A-Finger
®
drop-probe device is an air/electric system. It is designed to effectively eliminate accidents that
may arise when machine operators must have their fingers in close proximity to the point of operation on welder/riveter machines.
The DAF-100 is a safety device operated by air and cannot function without it.
SYSTEM REQUIREMENTS
Air..............................................35 psi @ 5 cfm minimum
Electrical ....................................100-240 V AC, 47-63 Hz @ 1 Amp
Relay output contacts ..................5 Amps @ 250 V (Terminals 15-16 and 17-18)
SEQUENCE OF OPERATION
Upon actuation of the foot switch, the sensing probe travels downward toward the workpiece. As long as there are no obstructions detected by the
sensing probe, the machine will complete its cycle. If the sensing probe detects an obstruction (down to 1⁄4” above the workpiece), the machine
will not be allowed to complete its cycle. Clear the obstruction and reactuate the foot switch to complete the machine cycle.
The sensing probe must be set to the proper safety distance—
1
⁄
4
” above the workpiece.
Note: For two-stage machine operation, actuating the foot switch beyond first-stage operation will initiate second-stage operation once the sensing
probe detects that it is free from obstructions.
ADDITIONAL COMPONENTS THAT MAY BE REQUIRED
• Foot switch
• Air cylinder—for mechanical to electrical conversion
• Dual-solenoid or single-solenoid air valve assembly
• Air lockout valve
