3.1.1 MOUNTING THE “C” RAIL
3.2 ASSEMBLY & INSTALLATION OF THE SAFEDGE PROFILE
3.2.1 Cut the Safedge Profile to length.
Profiles without coasting chamber should
be cut with rubber shears.
Profiles with coasting chamber should be
cut with a fine tooth saw.
Holes drilled on

6.2.1 Profile Cleaning
The Profiles should be kept clean of deposits such as swarf and other materials to prevent damage or
dead-zones. It is permissible to use warm water and a mild detergent to clean the surface area.
DO NOT USE SOLVENTS.
6.2.2 Routine maintenance inspection and test - ( recommended weekly or after repair)
Stop the machine, clean the Profile(s) and allow to dry off. Inspect the surface of the Profile for
damage. Any damage that punctures the profile could let material or liquid in. It must be dealt with
immediately. Check that all end caps, corners and joints are secure and free from damage. Damaged
parts must be replaced immediately.
Test the Profile operation. Two people may be required, one to press the Profile and one to observe the
operation of the control unit. On systems using Manual reset mode, the reset button must be
continuously pressed. Check that the RUN “Green” LED is illuminated when the profile is not pressed
and that the STOP “Red” LED is illuminated when it is. Start the machine, press the Profile and check
that the machine stops immediately.
If these checks reveal any problems, do not allow use of the machine until they are rectified. Record all
inspections and tests in a written log.
6.2.3 Thorough examination and test - ( twice yearly or after repair)
To be undertaken by a person competent in electrical and mechanical engineering.
a) Carry out tests at 6.2.2
b) Isolate the power source to the machine and Safedge system. Observe electrical safety
precautions.
c) Inspect the Profile and components thoroughly for mechanical damage.
d) Disconnect the wires to the Profile at terminals Z1-Z2.
e) Connect the wires from the Profile to the input of an ohmmeter. One person should now press the
Profile with one hand at every point on the strip. The resistance should measure 6K  +/- 10% when
the profile is not pressed and no greater than 1K when it is.
If these checks reveal any problems, do not allow the use of the machine until they are rectified.
Record the inspection and test in a written log.
