Test for Safety and Proper Operation
1. Test that the gantry head E-stop scanner activates the E-stop when an obstacle is
in its path. Even if the machine seems to be working fine, the E-stop capabilities
must be tested! We suggest using a wooden T as described in the
RoofTracker
III
equipment manual.
2. If it does not E-stop properly, contact MiTek Automation Solutions Customer
Service immediately and do not attempt to use the machine. Lockout/tagout the
machine until the issue is resolved.
3. Perform all additional safety tests from the safety chapter of the
RoofTracker III
manual to verify that the gantry head operates correctly.
New Operating Method
Reset Button
Upon the completion of this service bulletin, the gantry head controls will operate
differently. When the gantry head is traveling in either direction, if the scanner observes an
obstacle in the direction it is traveling, it will slow down, then stop before reaching the
obstruction. Movement in the opposite direction from the obstacle is unaffected. With the
obstacle detected, you can move the gantry head in the opposite direction without pressing
the Reset button to allow you to safely remove the obstacle.
Beacon Light
• The light blinks yellow (amber) when the machine is running.
•
NEW!
The light turns off when ONE scanner is tripped, letting you know the
gantry head can move in only the direction opposite of what it was just traveling.
• The light blinks red when an E-stop pushbutton is activated or when BOTH
scanners are tripped.
• The light is green when ready to operate.
New Schematics
New electrical schematics came with this kit. Replace your old schematics with these
updated pages so maintenance personnel are always working from the correct set.

WARNING
CRUSH HAZARD!
The success of the procedures performed must be verified as
described in the Safety Test section of the equipment manual.
Not testing properly could result in an E-stop failing to stop the
machine.
