Select the mounting locations so that the following conditions are satisfied acc. to EN 1088:
For doors/flaps that swing open, the position of sensor and actuator is opposite the hinge side.
The position of sensor and actuator allows the cut-out distance Sar to be reached upon opening of
the moveable guard.
The position of sensor and actuator makes it impossible to reach or step behind the moveable guard.
Make certain that the gap dimension between the fixed and moveable part of the guard is not wide
enough for reaching or stepping behind.
The position of sensor and actuator makes it impossible for a person to reach the dangerous area
during the stopping time of the machine after the guard is opened.
The position protects the sensor from physical shocks and vibrations that exceed specifications (see
chapter 13 Technical data ).
Adjacent Magnetically Coded Sensors must be separated by at least 50 mm.
The position of sensor and actuator must not lie within the range of influence of blasting agents or
magnetic particles.
Mounting on ferromagnetic materials (e.g., iron, nickel, cobalt) is to be avoided.
When mounting on stainless steel surfaces, spacers are to be used and the safety-related switching
distances are to be inspected.
The position of sensor and actuator must facilitate form-fitting mounting.
Accessible to qualified personnel for testing and replacement
Cannot be manipulated by operators though removal, turning, short-circuiting (e.g., by means of cov
-
ered mounting)
In the following example, the MC388x sensor is mounted on the front of a sliding gate. The switching condi
-
tion is activated by the actuator approaching from below.
The protective function of the sensors is only ensured if used in the intended area of application and if
they are mounted professionally.
Mounting may only be performed by competent persons.
Observe the relevant standards, regulations and these instructions.
Do not use the sensor in areas under the influence of strong magnetic fields.
After mounting, check the sensors for proper function
The protective function of the sensors is only ensured if, after the guard is opened, the dangerous
process can be safely stopped before it is reached by a person.
Mount the sensors with an adequate safety distance to the danger zone.
Take all delay times into account (e.g., the response times of the control elements, the stopping time
of the machine)
.
The alignment of sensor and actuator within the scope of start-up is to be performed only by trained
personnel.
Observe the data sheets and mounting instructions of the individual components.
