Instruction Manual for Connecting Sensors on Pillow Block Bearings
Temperature Monitor, Alarm System, Embedded Thermocouple and
Transmitter, Vibration Accelerometer, and Proximity Switch
Bearing Temperature Monitor-Alarm System
A. Connection to a PLC:
– Use an AC input card 120 VAC
– Cards available from Allen Bradley for SLC 500 are
1746-IA4, 1746-IA8 and 1746-IA16
B. If no PLC is used, the DODGE Light and Buzzer Alarm
Module can be used (DODGE Part No. 063524).
Connections are shown below.
DANGER: The user is responsible for conforming
with the National Electrical Code and all other
applicable local codes. Wiring practices, grounding,
disconnects and overcurrent protection are of
particular importance. Failure to observe these
precautions could result in severe bodily injury or
loss of life.
I. Bearing Temperature Alarm Monitor System:
1. A complete installation, Pillow Block with temperature
switch, conduit, and alarm is shown in Figure 1. Items
supplied by DODGE are the Pillow Block with
temperature switch and the alarm monitor. Conduit,
wires, and liquid tight fittings are supplied by the user.
2. A DODGE Pillow Block with temperature switch mounts
on the shaft exactly like a standard pillow block
.
II. Alarm Monitor Installation:
1. Install the alarm monitor in a visible and close safe
place using the four mounting holes on the back of the
enclosure.
2. Remove the enclosure cover by removing the two
screws on the front. (See Figure 2)
3. Install a conduit between the monitor and the bearing
using
1
/
2
" liquid tight fittings.
4. Use 16 AWG wires installed in the conduit to connect
the temperature switch to the alarm monitor.
5. Verify that AC power is disconnected and locked out or
tagged at the power source. Bring AC power wires to
the top of the alarm monitor and secure using
1
/
2
" liquid
tight fitting.
6. At the bearing remove the temperature switch cover,
connect the two leads of the temperature switch to the
two wires installed in step 4 above using approved wire
nut connectors and reinstall the cover.
7. Connect the end of one wire that is connected to the
switch to one end of the fuse (6). Connect the second
wire from the temperature switch to the joint (12).
8. Connect the black (hot) wire from the power source to
the other end of the fuse (14). Connect the white
(neutral) wire to lead (13). Connect the green (ground)
wire to the ground screw (7) on the back of the monitor.
Make sure the screw is tight and the wire is secure.
9. Replace the cover and secure with the two screws
.
