DESCRIPTION
When programmed as a Sensor Controller, Model 84530 wiII
verify delivery of Iubricant into a bearing
The Sensor Controller can only detect faults which occur
between the sensor (located in the delivery Iine at the bearing
lube inlet) and the flow source. Continuous flow or no flow during
the delivery cycle are both signaled as a fault by this system.
A minimum of 30 seconds between the end of one flow to the
beginning of the next flow is required for detection.
Sensors wiII function at any pressure up to 6,000 PSIG. The
temperature of the material which is to be delivered past the
sensors must be between 32° F to 145° F for effective operation
of the system. Viton seals and checks in the sensors allow their
use in systems distributing synthetic lubricants as well as
petroleum based lubricants. For reliable operation, sensors
can only be used with Model 84530.
When power is turned on to the Controller and a Lube
cycle is immediately initiated, a sensor fault may occur
due to the sensors not having enough time to warm. It is
recommended that the Delay Alarm be set at 2 in order to
prevent a nuisance alarm.
An external switch (contact closure) or an external signal
(120/230 VAC) wiII initiate a scan period (amount of time that
the sensors are scanned for lube flow). The scan period IS the
time that the external switch IS closed.
When the external switch closes the amber Iight turns on and
the timer on the display begins timing up from zero, indicating
the amount of time the external switch has been closed. If the
sensors are satisfied while the external switch is closed the
amber Iight wiII turn off. When the external switch opens the
timer on the display IS reset to zero and begins timing up again,
indicating how long since the last scan period
If the sensors are not satisfied while the external switch is
closed the following will happen:
Amber Iight on door remains on.
The timer on the screen is reset to zero and begins timing up
Indicating when the last scan period took place.
If, after thirty seconds following the external switch opening,
the sensors still have not been satisfied and the delay alarm
counter has reached its set value the following will happen
Red light on door turns on
Alarm relay contact closes
Alarm message wiII alternate with Scan Timer on
enclosure door
If lube flow takes place while the external switch iS open, the
fault wiII be cleared However, the next time the external switch
closes the amber Iight wiII not turn on
Due to the numerous options available, the customer can field
program the controller to match the system requirements
Programming is easily accomplished by following a user friendly
menu displayed on the LCD and pressing the active buttons
beneath the display An internal jumper pin provides security
against unauthorized programming All programmed parameters
are automatically stored in a nonvolatile memory A Review
Screen can be easily activated to display what has been
programmed Programmed values can be changed
whenever necessary
There are three Iights on the enclosure door to Indicate the
status of the system
Green - Power On
Amber - Sensors are waiting to be satisfied.
Red - Alarm
If an alarm occurs, the cause of the alarm wiII appear on the
LCD Turning off power to the controller when in alarm will reset
the alarm
The LCD is capable of displaying the following messages
Amount of elapsed time since the External switch opened
Amount of elapsed time that the External switch has
been closed
Number of times each bearing has received lube
Indicates what sensor did not receive lube
Indicates what sensor has a broken wire
Indicates what sensor has a shorted wire
