Setup example for the TM-2100 series 2 "Detect the gear with 60 gear teeth with the MP-981 and display the rotation speed with ○○○○ r/min"

The setup method to display the rotation speed ○○○○ r/min after the detection of the gear with 60 gear teeth with the MP-981.

 

When you setup the TM-2100 series (the TM-2110, the TM-2120, the TM-2130 and the TM-2140), please pull out the body from the case as shown in the following figure 2. Please finish the setup of the TM-2100 series unit before the wiring of the power cable or signal cable.

 

 

The signal cable connection with the MP-981

 

Connects the signal cable MX-705 (5 m) as shown in the following figure 1. When the needs of the long cable which is more than 5 m, available to make with the specified length.

 

 

 

Setup of the TM-2100 series

 

Please follow 1 to 4 steps shown in the following figure 2. This is the additional explanation of the meaning of the setup. Please refer to the instruction manual for the details of the function.


If you wish to display [○○○○ r/min] with the detection gear with 60 gear teeth + the MP-981 + the TM-2100 series, setup the unit with multiplier/index [1.0000×1] and with no decimal point.

 

 

1. AC-DC setup

The signal from the MP-981 is square wave of 5 V in high level, so setup as [DC]. Generally, when the signal is square wave, setup as [DC] and when the signal is sine wave, setup as [AC].

 

2. Voltage input, filter

Because of the signal from the MP-981 is a square wave voltage, setup the 4-bit switch of the figure 2 of 2 as [bit 1: OFF (voltage input side)], [bit 2: OFF (no filter)] and [bit 3 and 4: OFF (these are free switches)]. If the signal is open collector, setup switches as [bit 1: ON (contact point input side)] and [bit 2: OFF (no filter)]. If the signal is contact point input, setup a switch as [bit 1: ON (contact point input side)] and to prevent the chattering of the contact point, setup a switch as [bit 2: ON (filter available)].

 

3. How to calculate the coefficient (multiplier×index)

 

 

Setup the 8-bit switch of the figure 2 of 3 as [bit 3 and 4: OFF] and [bit 5: ON] (coefficient=1). Moreover, setup switches as [bit 6, 7 and 8: OFF] (no decimal point ○○○○). Enables to setup off to third decimal point. Setup the rotary switch in the figure 2 of 4 as [10000] (multiplier=1.0000).

 

4. Wide range

Setup the 8-bit switch of the figure 2 of 3 as [bit 1: ON], the frequency range becomes wide and start the measurement from the minimum measurement range of 0.1 Hz (0.1 r/min). During the stop period, it decides 0.1 Hz so you need maximum around 20 s measurement time until the display shows 0. When you setup the switch as [bit 1: OFF], the minimum measurement frequency range becomes 1 Hz (1 r/min) or more. During the stop period, you need around 1 s until the display shows 0. Also, setup the switch as [bit 2: OFF] (free switch).
