PART NUMBER 37545 SMART MONITOR 120VAC 4-20MA OUTPUT

Description:
Smart Monitor 37545 converts rotary shaft speed (RPM) into analog 4-20mA output . This 
allows “true-slip” monitoring during the critical ramp-up period of conveyors . The Smart 
Monitor 37545 interfaces directly with the customer’s PLC . The Smart Monitor conveniently 
mounts inside an existing electrical panel or O .E .M . control box . The aluminum mounting 
plate is removable for mounting to DIN rail . The up-front LCD screen conveniently shows the 
current RPM in real time . 

Installation:
1 .  Disconnect AC power before proceeding with installation

2 .  Mount the Smart Monitor inside and existing control panel or other suitable protective 

enclosure . See Figure A5 .3 for Smart Monitor mounting dimensions .

3 .  Table A5 .1 shows connection details for the terminal strip . Make needed connections .

4 .  Install Smart Roll . See Section 2: “Installing and Mounting the Smart Roll .”

Set-up and Display Indicators:
When power is applied to the unit, the display will show the following: “000” RPM (Displays 
the actual RPM from the remote speed sensor) .

“Line Open” – If displayed, indicates user should check 4-20mA line .   0-500 ohm is 
maximum line resistance .

“10-XXXX RPM” – Displays the current speed range . If this is NOT the correct range required 
for your installation, you can select from 23 other preset speed ranges by following the steps 
below:

1 .  Depress and hold the “set” button for approximately 4 seconds . The display will now 

change to show ranges from 100 RPM top range to 6000 RPM top range .

2 .  Now using the “arrow” keys, select the desired range from the list .

3 .  With the correct range “highlighted,” depress and hold the “set” button for approximately  

4 seconds . The display will now change back to normal operation with the new RPM 
range shown on the screen .

NOTE: If you do not make a selection within approximately 10 seconds, the display will go 
back to normal operation and keep the existing speed range .

NOTE: This new model has ALL the “previous style” Smart Monitor speed ranges included in 
the firmware, this allows for the models to be replaced without having to change computer 
programming .

Application / Speed Information:
All models have a preset low end RPM range of 10 RPM (0 .1666 Hz X 60) .  
The following formulas/examples can be used to determine the Frequency  
Range (SPAN) and corresponding 4-20mA output at any monitored speed .

1 .   Convert top end RPM into a Frequency in hertz (Hz) . 

        XXXX RPM / 60 = XXX .X Hz

2 .   Subtract Frequency in hertz from 0 .1666 Hz (10 RPM) 

     XXX .X Hz – 0 .1666 Hz = XXX .X SPAN in RPM’s

3 .  Divide the SPAN in RPM by 160 = RPM’s per each 0 .1mA increment  

of output . 
     XXX .X RPM / 160 = XX RPM per  .1mA output
