1 PulseTM SystemPulseTMSystemThe Pulse system s automated 24/7 belt monitoring represents a significant advance over conventional inspections. Its assurance of belt integrity sets a new standard for monitoring, maintenance and 16 GEN 027 (0405) Otis Elevator Company. All rights of 2 MAJOR BENEFITSC ontinuous monitoring brings peace of mind Immediate, automatic reporting enhances safety and eliminates service interruptions for belt inspections Advance notice of belt wear helps manage maintenance schedulingSuperior monitoring while eliminating inspection downtimeOtis Pulse system continuouslymonitors and ensures the integrity of the Gen2 TMflat coated-steel belts. Conventional wire ropeinspection relies on periodic visualexamination of the lifting ropes,which requires taking the elevatorout of service. These manual inspections involve examining the rope for broken exteriorstrands. This time-consumingmethod can leave broken interiorstrands undetected.

AThe electricalresistance of each cord is propor-tional to its cross-sectional area,which is a measure of its remaininguseable life. The Pulse system con-tinuously monitors this resistanceto determine when the belts shouldbe belts steel cords are indi-vidually monitored via conductingpins Bthat penetrate through the belt coating to make electricalcontact with each cord. The system continuouslymonitors wearand provides an automatic alertmore than a year in advance ofwhen the belts need timely notification allows forconvenient maintenance addition, the Pulse systemsignals an alarm if it detects jacketdegradation or a broken cord.

3 Thesystem also provides an alarmwhen the cords have reached theirwear-tolerance limit. In responseto an alarm, the car is sent automatically to the next landing and the system is shut down. The service organization is notifiedthrough a standard callback or via the REM (remote elevatormonitoring) Pulse system offers severalreporting options. On elevatorsequipped with REM service, the sys-tem can remotely report belt wearand system faults for rapid diagnosisand response.
