Operation - Honeywell FF-SPS4 Series Installation Manual

Operation

The FF-SPS4 Series safety perimeter devices are designed so that a malfunction or an
interruption of the sensing field will cause the perimeter device to generate a STOP signal
within a maximum of 20 milliseconds. This STOP signal will be generated automatically if a
malfunction occurs within the safety device. All other machine control components that affect
safety should also be designed to the same high level of operation.
IMPROPER CONTROL SYSTEM
Ensure the safety related parts of the control system and/or its protection devices, as well as
its components, are designed, selected, and combined so as not to prevent the loss of safety.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER MACHINE REACTION
• Ensure the machine control is capable of stopping the machine at any point in the cycle.
• Ensure that a loss of power does NOT impair stopping action of machine.
Failure to comply with these instructions could result in death or serious injury.
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.
The FF-SPS4 devices are thru-scan devices. The emitter sends an infrared light beam that is
detected by a photoreceiver in the receiver unit. The emitter is optically synchronized with the
receiver. No interconnecting cables are required. In addition, the emitter and the receiver are
not matched, easing maintenance.
