• For use in functional stop category 0 applications per NFPA 79

and EN418

• 6 amp safety output contacts

WARNING . . .

This Emergency Stop Safety Module is not a point-of-operation guarding device, as

defined by OSHA regulations. It is necessary to install point-of-operation guarding devices, such as safety

light curtains and/or hard guards, to protect personnel from hazardous machinery. Failure to install point-of-

operation guards on hazardous machinery can result in a dangerous condition which could lead to serious

injury or death.

E-Stop Safety Module – Model ES-FA-6G Initial Checkout Procedure Checkout procedure: CAUTION . . . 1) Remove power from the machine control elements. 2) Activate the E-stop switch (open its contact). 3) Apply power to one side of the E-stop switch. No indicator should be ON at this time. If any of the three indicators is ON, disconnect the power to the E-stop switch, then check all wiring and the E-stop switch. Return to step 2 after the cause of the problem has been corrected.
