FF-SPS4 Installation Manual
IMPROPER POINT OF OPERATION PROTECTION
Do NOT use FF-SPS4 Series safety perimeter devices in point of operation applications.
Failure to comply with these instructions will result in death or serious injury.
Point-of-operation is defined as that area where a machine performs work (such as cutting,
shaping, boring, or forming) on a material.
Figure 1-3 Perimeter Protection (two beam minimum)
FF-SPS4 circuitry is based on a permanent self-checking principle and meets the
requirements of IEC 1996 EN 61496 part 1/2 European standard for type 4 Electrosensitive
Protective Equipment (ESPE). A faulty component in the device will be immediately detected
and will generate an emergency stop signal to initiate the arrest of machine motion. If an
internal failure is detected, operation of the machinery is prevented until the condition is
corrected.
