AC 110V Digital LED Tachometer RPM Monitor Over/Under Speed Alarm Hall Sensor

Parameter

• Working voltage: AC 110-230V

• Input signal: signal voltage DC 5-30V , Proximity / Photoelectric / Electronic Switch NPN Normal Open (noliner change signal)

• Speed units :

\"1\"means: 000.0 r/s ~ 999.9 r/s

\"2\"means: 00.00 r/s ~ 99.99 r/s

\"3\"means: 0000 r/s ~ 9999 r/s

\"4\"means: 0000 rpm ~ 9999 rpm

\"5\"means: 00.00 rpm ~ 99.99 rpm (ultra-low speed function)

• Accuracy: ±(2%+1)

• Conversion rate: standard is 2 times/second , ultra-low speed function changes with signal time

• Minimum speed: 3 rpm with ultra-low speed function , 30 rpm for other functions

• Alarm time: 40 seconds for ultra-low speed function , 4 seconds for other functions

• Output type: switching signal

• Output contact: Normally Open , Normally Close

• Sensor: NPN NO

• Screen: 4-digits , 0.56\" LED display

• Working temperature: -10 ℃ ~ 150

When an alarm output is available , the decimal number in the lower light corner of the fourth digit lights up

1: when the detection speed is greater than the upper limit value or less than the lower limit value , and the correct delay time is set , there will be an alarm output.

2: \"HHHH\" is displayed outside the range , and if the upper limit alarm function is not turned off , there will be an alarm output.

3: When there is a lower limit setting , there is no alarm output when the power-on standby display shows \"0000\" ; when the signal is detected and the returns to \"0000\", a lower limit alarm is output

Parameter Setting

1. press and hold \"Set\" button for 3 seconds to enter parameter setting . If there is no operation within 6 seconds, it will automatically exit and no storage will be made

2. press the SET button continuously to set different parameters: H1, 900e0, H2, 0000, H3, 0004......until H9 parameter is automatically stored and closed

3. Press the \"-\" button to move to the parameter position that needs to be adjusted , Press the \"+\" button to adjust the value
