Figure 32. Entry/Exit Application using four pairs of opposed-mode photoelectric sensors for mute devices
A ≥ Line speed (ft/sec) x 0.1 sec.
B ≥ Line speed (ft/sec) × 0.5 sec. if receiver Sync Beam (Beam 1) is blocked
B ≥ Line speed (ft/sec) × 0.1 sec. if receiver Non-sync Beam is blocked
Length of carrier basket > A + B + (D x 2)
(NOTE: M4 must be blocked before M1 clears.)
D < Line speed (ft/sec) × 3.0 sec., but beams M1 and M2 must be far enough apart to prevent an individual
from triggering both sensors simultaneously.
CAUTION: Four Mute Device Applications When four mute devices are used, a maximum mute time limit
should be configured. Mute options 2, 4, or 6 should be used with a maximum mute time of 60 seconds.
CAUTION: The Mute Enable function should be used to enforce one-way muting when four muting
devices are used.
WARNING:
•
It must not be possible for personnel to walk in front of, behind, or next to the muted object
without being detected and stopping the hazardous motion.
• Failure to follow these instructions could result in serious injury or death.
• Use supplemental guarding to prevent personnel from entering the hazardous area during a mute
condition.
