An apparatus includes: a housing that encloses a controller configured to control a conveyor system; and an attachment assembly attached to a first side of the housing. The attachment assembly is configured to attach the housing to a side channel of the conveyor system, and the attachment assembly includes an attachment piece, the attachment piece including: a first latch member configured for connection to a first interface on the side channel of the conveyor system; and a second latch member configured for connection to a second interface on the side channel of the conveyor system. When one or more of the first latch member is connected to the first interface and the second latch member is connected to the second interface, the housing is attached to the side channel with a space between the side channel and the first side of the housing.

Attachment assembly for a controller housing

A monitoring system for detecting faults in an apparatus, such as a ski lift, employs a communication network onto which a sensor bus controller periodically transmits a safety message and receives a echo of each safety message. Different sensors are coupled to sensor adapter modules that in turn are connected in a series to the communication network. After the last sensor adapter module in the series, each safety message is echoed back along the communication network. Each sensor adapter module, upon receiving a safety message, increments a count in that message and transmits the resultant safety message to another module. When a sensor indicates a fault condition, the associated sensor adapter module blocks propagation of safety messages along the communication network. The sensor bus controller determines, in response to a failure to receive the echo and to the count in the echo, whether a fault occurred.

System for monitoring a plurality of sensors

An apparatus monitors and controls application of three phases of alternating voltage to a load by detecting the sequence of the three phases. A switch module is operated, in response to the detected sequence, to ensure that the three phases are properly applied to the load, even if the utility lines are improperly connected. The monitoring also senses loss of a phase in which case the switch module disconnects the application of electricity to the load. The apparatus is capable of being used with different loads that operate at different peak to peak levels of alternating voltage.
