Connections and Setup

Overview

IMPROPER ELECTRICAL INSTALLATION
• Each safety mat activation must stop dangerous machine operation within the response
time of the components.
• Clearing the sensing zone must not start dangerous machine operation. When restarting
machine operation, a normal machine control start sequence must be used.
• If electrical power is removed from a machine, its restoration must not initiate dangerous
machine operation; a normal machine control start sequence must be used.
• If a safety mat system is activated, the machine must NOT be able to restart.
• The external safety relays located between the safety outputs and the machine control
circuitry must be monitored.
• In the event of component failure, the machine control circuitry must stop dangerous
machine operation and prevent the next machine cycle activation.
• A Programmable Logic Controller must NOT be able to override a manual restart function.
• Strictly adhere to all electrical connection instructions and local wiring standards.
• If the module is in the automatic operation mode, another part of the safety control circuitry
must keep the latched function engaged.
• To keep the latched function engaged and maintain control reliability, use safety
components only. Do not use a programmable logic controller (PLC).
Failure to comply with these instructions could result in death or serious injury.
This section contains information about fiber optic and electrical connections, interfacing and
the setup of the control unit and safety mat. According to ANSI B11.19 - 1990, the safety mat
shall be interfaced with the machine control system so the mat's stop signal causes immediate
stopping action of the machine and shall require the reinitiation of the operator's control prior
to the start or continuation of machine motion. Connection of the safety mat to the machine
control circuitry must be carried out in such a way that the external relaying (safety relays with
positive-guided contacts) used in the interface are systematically self-checked (monitored)
before each machine cycle. Using safety relay technology, Honeywell safety control modules
(FF-SR Series) provide cross monitoring and ensure proper machine control operation.
