• The momentary N.O. button on the enabling device initiates the machine function.

4. Additional logic, such as a safe speed / zero speed signal, may be required to ensure that the operator(s) are not exposed to

hazards generated from automatic machine operation.

5. Multiple actions are required to return the machine to automatic or production mode, including closing the guard and resetting the

guard-monitoring safety module.

WARNING: Wiring of Arc Suppressors
If arc suppressors are used, they MUST be installed as shown

 across the actuator coil of the stop

control elements (MSCs or MPCEs). 

NEVER install suppressors directly across the output contacts

of the Safety Device or Module.

 It is possible for suppressors to fail as a short circuit. If installed directly

across the output contacts, 

a short-circuited suppressor will create an unsafe condition which could

result in serious injury or death.

Checkout Procedures

Initial and Daily Checks

Verify the functioning of the enabling device at initial installation (by a 

qualified person

 ), 

daily or before each use

 (by a 

desig-

nated person

 ), and as part of the regular periodic checkout procedure listed below

 to ensure proper operation.

(A

 qualified person

 possesses a recognized degree or certificate or has extensive knowledge, training, and experience to be able to solve

problems relating to the safety switch installation. A 

designated person

 is identified in writing by the employer as being appropriately

trained to perform a specified checkout procedure. )

1. Inspect the device for breakage or damage and the interconnect cabling for crushing, cuts, or wear.

2. Inspect the device for loosening or damage to the mounting hardware or means of storage.

3. With the enabling device selected (e.g., bypass or maintenance mode, inch/jog) and the safeguard disabled (e.g., interlock gate/

guard open), verify that:

• The bypass indicator illuminates, and

• Hazardous function(s) can not be initiated when the enabling device is not actuated (position #1).

4. Actuate the enabling device (squeeze to position #2) and initiate hazardous machine function(s). Verify that the hazardous function

ceases when the device is released (returned to position #1) or fully squeezed (position #3).

5.

If more than one enabling device is used, perform this procedure individually for EACH device.

Periodic Checks

qualified person

 (as defined above) should check for the following on a periodic schedule determined by the user, based upon the

severity of the operating environment and the frequency of switch actuations. At a minimum, this should take place once a year (lockout/

tagout procedures for controlling hazardous energy may be required):

1. Inspect the wiring chamber for signs of contamination, deterioration, loose connections, or damage.

2. Inspect the sealing at the cable entry and all electrical wiring for continuity and damage.

3. Verify that wiring and installation conforms to the instructions in this document and that there are no signs of tampering or defeat.

4. Perform the initial checkout listed above.

See also the machine manufacturer's recommendations for additional instructions.

 If any of these checks cannot be verified, do not

attempt to use the enabling device until the defect or problem has been corrected.
