The HMC Control System is a Surface / Wall Mounted enclosure, which contains from 4 to 12 Selector Switches with Indicator Lamps which are used to select the Hoists being Controlled. Once a hoist or group of hoists has been selected, a Master Up/Down ( Dead Man) Push Button will raise or lower the hoists selected. The System also contains an On/Off Key Switch which will disable the entire system when the Key is in the off position. A re-set Emergency Stop Button is provided that will trigger a contactor (Supplied by others unless specified as part of the Desisti System) which will trip the breakers feeding the Hoists and thereby shutting down the entire hoist system in case of an emergency.
