PART NUMBER SMART MONITOR VAC MA OUTPUT
Description:
Smart Monitor 47269 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 A5.8 for Smart Monitor mounting dimensions.
3. Table A5.6 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:
5. 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.
6. Now using the “arrow” keys, select the desired range from the list.
7. 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 the output.
XXX.X RPM / 160 = XX RPM per .1mA output
