PART NUMBER 47268 SMART MONITOR 9-36 VDC
Description:
The Smart Monitor 47268 provides an under speed switch by monitoring 6-3,000 pulses per minute (PPM) and has a user-programmable
0-30 second ramp-up timer . The Smart Monitor is designed to be located in an electrical panel or O .E .M . control box . A removable plate
allows for mounting to a DIN rail . The digital display shows the current PPM in real time . This eliminates setting “guesswork” by constantly
showing the actual PPM being monitored .
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 .5 for Smart Monitor mounting dimensions .
3 . Table A5 .4 shows connection details for the terminal strip . Make needed connections .
4 . Install Smart Roll . See Section 2: “Installing and Mounting the Smart Roll .”
Trip Point Set-up:
Apply power to Smart Monitor . If this is the first time powering unit up, the default trip point
is 6 RPM or PPM, the built-in ramp-up timer is disabled and the relay is off (TRIP: 0006 /
RAMP: 0S / REL: OFF) . Read through the following instructions before starting the set-up
procedure .
• Momentarily depress the down arrow button once to highlight “TEST .”
• Momentarily depress the down arrow a second time to highlight “TRIP .”
• Momentarily depress the SET button to begin setting unit to the trip speed desired,
starting with the 4 digit (the 1000s place) . When highlighted, use the up/down arrow
buttons to change number as needed . When 4th place is set correctly, momentarily
depress the SET button to begin setting the 3rd (100s place) digit . Again use the up/down
arrow buttons to change the number . When set correctly, momentarily depress the SET
button to begin setting the 2nd (10s place) digit . Use up/down arrow buttons as before to
change the number, and once set, momentarily depress the SET button to begin setting
the 1st and final digit .
• Review your settings for accuracy . If a digit needs to be adjusted, momentarily depress
the SET button one or more times to get to the proper digit, then use the up/down arrows
to switch number and when satisfied, press and hold the SET button – the RPM setting
will highlight and then go back to normal . The SET button can then be released . The RPM setting will be maintained in non-volatile
memory until changed by the operator .
Ramp-up Timer Set-up:
The default setting for the ramp-up timer is 0 seconds (timer disabled) . To set the timer for a 1 to 30 second ramp-up period, follow the
procedure below:
• Momentarily depress the down arrow to highlight “RAMP .”
• Momentarily depress the SET button to highlight the timer in seconds .
• Use the up/down arrow buttons to increment the timer from 0 seconds up to a max of 30 seconds .
• When satisfied, press and hold the SET button – the timer setting will highlight then return to normal .
Testing Procedure:
A test function has been provided to allow the operator to de-energize the internal control relay and stop the monitored equipment . To
activate a test shutdown,
• Momentarily depress the down arrow button once to highlight “TEST .”
• Depress and HOLD the SET button for approximately 3 seconds – the control relay will de-energize .
• Release the SET button . There is a safety delay that will keep the control relay off for 10 seconds after it has de- energized . The relay will
automatically re-energize after the delay if RPM speed above the programmed trip point is detected .
