9. Wiring diagram Never change or modify the basic electrical settings of the granulator, without first obtaining permission from Conair. If the granulator settings are changed, the machine can be seriously damaged. All Warranties and ConairÕs Product Liability will be void, if the basic settings of the granulator are changed.
9.1 Current sensing relay The granulator can be equipped with an optional current sensing relay to control the feed equipment. The current sensing relay detects the mill motor current consumption and can temporarily stop accessories such as conveyors, roller feeders etc to avoid putting further material into the hopper, when the mill is running under heavy loading. The relay stops and re-starts accessory equipment automatically, without re-setting.
Example The granulator is equipped with a current sensing relay to control a conveyor. A motor of 7.5 kW has a rated current of about 15 A. When this star/delta is started, it pulls about 15 A/ i.e. about 9 A per phase. Relay setting: Motor size 15 A/ = 8,7 A per phase T1 Ð Start delay setting 0.1 second. T2 Ð Reaction time setting 3.0 seconds. A Ð Hysteresis 20 %. B Ð Limit value 30 %. C Ð Relay function N normal. The current transformer size is 30/1A. The current transformer is connected to E2 (1 A).
