Stall Alarm Specifications

If the cooling fans stop rotating while power is being supplied, an alarm signal is output.

Alarm Specifications

alarm activation speed	When locked
Output Mode	Open-collector output
Output Condition	Operation: L level (Internal transistor ON) When Locked: H level (Internal transistor OFF)
Maximum Rating	Maximum Applied Voltage: 30 VDC or less Maximum Inflow Current: 5 mA or less
Delay Function	None (To avoid alarm detection when the cooling fans start, an external delay circuit is required. The delay time should be 1 second min.)
