Chapter 3 Safety Mats - Two Zones
Circuit Status
No presence is sensed on both mat systems. All four contactors are off, and both
motors (hazards) are off. The system is ready for reset.
Operational Sequence
Press Reset 1 to enable the start of Zone 1. Press Reset to enable the start of
Zone2.
To gain access to either zone, the operator steps on the mat or presses the E-stop
but
ton. Both devices initiate an immediate stop command to its associated
hazard. An indicator at Plug-in terminal P200 and P201 show when someone or
something is on the mat or if the E-stop is pressed for that zone.
If the operator enters Zone 1, then only Zone 1 stops and Zone 2 continues to
ru
n. If the operator enters Zone 2, then both zones stop.
After leaving the Zone 2, the operator must press the reset button to enable the
re
start of Zone 2. After leaving Zone 1, the operator must press the reset buttons
for both Zone 1 and 2 to enable the restart the machine.
