Inspection And Maintenance; Overview; Operational Test - Honeywell SYA14 Series Manual

Overview

This section contains an operational test procedure, inspection criteria, maintenance
instructions, an indicator status and corrective actions table, and a troubleshooting flow
diagram.
IMPROPER MAINTENANCE
• Strictly adhere to all test, inspection, troubleshooting and maintenance instructions.
• Access to the control unit is restricted to adjusting excess gain (DT1, DT2), making ST
optical connections using snap-in clips, replacing supply fuses, and connecting wires.
• Do not touch any other components inside the control unit.
Failure to comply with these instructions could result in death or serious injury.

Operational Test

To ensure functional readiness, perform the operational test at least once a day and every
time the safety mat system is repaired or powered up. The operational test consists of one
person activating each mat sensor at a time by walking on each individual safety mat in the
sensing zone. The alarm output indicator must go immediately to the red condition and shall
never switch off while an operator is stepping in the sensing zone (see Connections and
Setup). All safety mats shall be activated and tested to ensure correct operation.
The control unit continuously checks the optical signal delivered by the safety mat sensors that
make up the sensing zone. If a significant signal shift is detected, the machine stop contacts
will open immediately. This feature ensures the nominal detection sensitivity of the safety
mat.
