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.			C	T1
Relay functions and normal settings:
T1	–	Start delay, prevents the relay from breaking
		on connection (0.1 - 10 sec).
		The default start delay is 0.1 seconds.
T2	–	Reaction time, prevents the relay from breaking
		during temporary high loading (0.1 - 3 sec).
		Default reaction time is 3.0 seconds.

A– Hysteresis, adjustable between 5 - 50% of the set limit.

Default hysteresis is 20 %.

B	–	Limit value, adjustable between 0 - 100 %.	A	T2 B
		Default setting depends on the current transformer size.
		Check the current transformer size and then check the
		default setting for this granulator.
C	–	Relay function, N = normal; I = inverted;
