2. PRODUCT OVERVIEW
The Watchdog Super Elite (WDC4) is a user-programmable, microprocessor controlled bucket elevator and
belt conveyor monitor. The control unit accepts signals from sensors for belt misalignment, belt speed &
slip, continuous bearing temperature, pulley misalignment and plug condition monitoring. The unit is able
to sound an alarm and provide shutdown control of the elevator or conveyor, and feeding system, when a
potentially hazardous condition is detected.
Microprocessors and electronics are housed in a self-contained wall mounted control unit. An LCD screen
on the front of the unit displays system status. Calibration and set-up parameters are accessed via a
password and front panel touch buttons.
The Watchdog Super Elite can also integrate into HazardMon.com ®, which is a secure cloud based hazard
monitoring solution providing status notications and data logging for bucket elevators and conveyors. Live
system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet
PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system’s
health is detected. An automated maintenance feature allows site operators to verify that all sensors on
the system are operational and working correctly.

4. FEATURES
BELT MISALIGNMENT DETECTION -
The Watchdog Super Elite offers greater exibility for belt misalignment monitoring. The supported methods
are:
METHOD DESCRIPTION APPLICATION
Contact
Force activated contact signal.
When contact from the belt occurs
an alarm is generated.
Standard method, most reliable for
misalignment detection.
Pulse
Continuous pulses are generated
by detecting a ferrous metal
source (bolts, buckets, chain).
Absence of pulses generates an
alarm condition.
Used for applications requiring
non-contact sensors.
Rub Block
Processes temperature
information from brass blocks
to detect belt misalignment.
When the belt rubs against the
brass block heat from friction is
generated.
Alternative detection method, not
recommended due to unreliability.
METHOD DESCRIPTION APPLICATION
Dedicated Speed Shaft rotation speed
measurement.
Standard method, most commonly
used.
Highest Pulse Rate
Speed determined by the detection
of ferrous metal (bolts, buckets,
chain) passing by the alignment
sensors.
Used for applications requiring
non-contact belt alignment
sensors.
Differential Speed A combination of both methods
listed above.
Used with variable speed drives
(VSD).
BELT SPEED / SLIP DETECTION -
The Watchdog Super Elite also offers greater exibility for belt speed/slip monitoring. The supported
methods are:

METHOD DESCRIPTION APPLICATION
Absolute Temperature (ABS)
An alarm is raised if the sensed
temperature exceeds the preset
trip point.
Simple bearing detection for over
heating, most commonly used.
Relative Temperature (REL)
An alarm is raised if the difference
between the sensed temperature
and the selected relative or
ambient source temperature is
greater than the preset trip point.
Used in addition to the rst method
and provides much earlier fault
detection. Especially useful in
cold weather as it is no longer
necessary to wait until the bearing
gets to a very high temperature
before a failure detected.
Rate of Rise (dR - delta R)
An alarm is detected if the bearing
starts to heat up at a rate higher
than the preset value in degrees
per minute.
Used in addition to the two
methods above, and provides for
an alternative fault detection for a
failing bearing.
HOT BEARING DETECTION -
The Watchdog Super Elite can monitor up to 8 NTC type temperature sensors (standard). This can be
expanded to a total of 20 NTC sensors with optional auxiliary boards. The supported alarm methods are:
AUXILIARY INPUTS -
The Watchdog Super Elite also has auxiliary inputs for pulley misalignment, plug condition or blocked chute
monitoring. These offer additional protection and prevent unnecessary costly downtime.
SETTINGS BACKUP & TRANSFER -
The controller is equipped with an SD card slot, and supports the ability to save and restore the system
settings from the memory card. This also allows system settings from one unit to be copied to another,
which is especially useful to duplicate settings on multiple controllers at the same location.
WDC4 CONFIGURATOR SOFTWARE -
The Watchdog Super Elite can be programed directly through the controller’s LCD menu screen, or by
using the WDC4 Congurator Software (Appendix C). The software tool makes programming the Watchdog
easier by providing all the system settings for each prole menu into one screen. Once a prole setup le
has been created, it can be saved to an SD card and then uploaded to the Watchdog. For remote sites,
the le can be emailed to an on-site technician, who can upload the le.
EVENT & ALARM LOGGING -
The last 40 events and alarms are logged and can be viewed directly from the Watchdog’s main LCD
screen. If an SD card is installed, all events and alarms (not just the last 40) are saved on the card. The
le can be imported into a spreadsheet program to create more detailed logging and trending reports.
HAZARDMON.COM CONNECTIVITY -
The Watchdog Super Elite has in-built network support for Hazardmon.com service connectivity. HazardMon
is a secure cloud based hazard monitoring solution providing status notications and data logging for
bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any
web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify
users whenever a change in the system’s health is detected. An automated maintenance feature allows
site operators to verify that all sensors on the system are operational and working correctly.

user must take into account any limitations which might be listed on the relevant certicates.
3. The box is supplied with 2 x 1-1/8 inch (28.5 mm) pre drilled holes in the bottom face. All
unused entry apertures must be sealed using component certied stopping plugs. The end user
must install component or apparatus certied stopping plugs and cable glands/conduit in strict
accordance with the manufacturer’s instructions. In order to connect conduit to the control unit
enclosure, use a CSA and/or UL certied Class II conduit hub (for example, a Myers™ hub) with a
suitable bonding (grounding) connection that is rated for the installation environment.
4. The enclosure must not be modied in any way, as this will invalidate the certication.
5. All wiring must be carried out in accordance with relevant codes of practice and/or instructions.
6. The voltage, current and maximum power dissipation shown on the label must not be exceeded.
7. The wiring installation must extend to within 1 mm of the metal face of the terminal.
8. All leads must be insulated for the appropriate voltage.
9. Not more than 1 single or multiple strand cable is to be connected to any terminal unless multiple
conductors have previously been joined in a suitable manner (e.g. boot lace ferrule) such that they
present a single connection point to the terminal.
10.A at-head or straight screwdriver of the correct size should be used to tighten terminals.

8. ELECTRICAL CONNECTION
All wiring must be in accordance with local and national electrical codes and should be undertaken by
an experienced and qualied electrician.
Always use dust/liquid tight exible metal conduit with approved ttings to protect the sensor cables.
Use rigid metal conduit to protect the cables from the sensors to the control unit. Conduit systems can
channel water due to ingress and condensation directly to sensors and sensor connections which over
time will adversely affect the performance of the system. As such, the installation of low point conduit
drains is recommended for all sensors.
All electrical connections are made via 3 sets of terminals provided as shown in image 1.
FUSE RATINGS -
In order to maintain the product certication, all fuses MUST be replaced with equivalent fuses at the
same rating. Failure to do so will invalidate the certication and any warranties which may exist.
Model WDC4V4C -
• F1, F2, F3, F5 200 mA maximum.
• F1 to F3 are used to limit the current available to the sensor inputs.
• F5 is used to limit the current available to the internal electronics.
• F6 is not used.
Model WDC4V46C -
• F1 to F3 2 amp maximum, used to limit the current available to the sensor inputs.
• F5 200 mA, used to limit the current available to the internal electronics.
• F6 2 amp maximum, used to protect the AC power supply.
NOTE
Recommended cable type is Belden 5508FE with 10 conductors each 22 AWG, shielded. Overall
outer diameter is 0.23 inches. Belden 5508FE wire colors are used in all of the sensor wiring
diagrams in section 9.
NOTE
To calibrate speed and utilize the Watchdog’s built-in alarm and shutdown capabilities, a motor
interlock (run signal) is required. For typical motor interlock wiring examples, review the wiring
diagrams for terminals 6 & 7.
Rotating parts can crush,
cut and entangle.
Do NOT operate with
guard removed.
Lockout power before
removing guard or
servicing.
