Cable mounting
The cable should be mounted so there is no force on Adam sensor in any directions. The cable should be fixed if
it’s connected to a moving object, for example a cable chain or a door. This can be done with for example two
cable clamps. This applies to all versions of Adam, including Adam E and Adam with M12-contact.
An improperly installed cable can damage the sensor.
Minimum safety distance
When using interlocking guards without guard locking to safeguard a hazard zone, the minimum allowed safety
distance between the guarded opening and the hazardous machine must be calculated. In order to ensure that the
hazardous machine motion will be stopped before it can be reached, the minimum safety distance is calculated
according to EN ISO 13855 (“Positioning of safeguards with respect to the approach speeds of parts of the human
body”).
The minimum safety distance is calculated according to the formula:
S = (K x T) + C
Where
S
= minimum safety distance (mm)
K
= approach speed of a human body; 1600 mm/s
T
= the total time from opening of the guard until the hazardous machine movement has stopped, i.e. including
control system reaction times and other delays (s)
C
= a safety distance taken from Table 4 or Table 5 of EN ISO 13857:2008, if it is possible to push fingers or a
hand through the opening towards the hazard before a stop signal is generated
NB: In some cases, T might be reduced by the opening time of the guard until the opening size permits access of
the relevant parts of the body. Refer to EN ISO 13855 for further details and EN ISO 13857 for specified values.
Installation precautions
Note that the sensing distance may change when the sensor is fitted onto metals. Mount Adam and Eva to
the intended operating position and test and adjust the sensing distance. Distance plates DA1 can also be
used between the sensor and mounting bracket to avoid direct contact with the metal.
Use max tightening torque 2 Nm when mounting the sensors.
Control that Adam and Eva are aligned in parallel to each other.
The cable to Adam should be U-shaped if the units are mounted in wet areas.
Warning!
All the safety functions must be tested before starting up the system.
