Centro-Matic® Automated Lubrication Systems

System Controls

Selecting the right controls for your automated lubrication system is one of the last steps in the design process. Several
different models may be chosen to control power-operated pumps, depending on the degree of automation and monitoring
required. Your Lincoln representative will assist you in specifying the correct model.

Options range from simple timers to fully-automated system controllers and monitors. Basic timers allow you to set the
interval between lubrication cycles. More sophisticated monitors control the frequency of lubrication, oversee system
performance and can sense lubricant flow to each bearing while showing system status and alarms on a LCD display panel.
Monitors may be interfaced with machine control systems to protect your equipment from harm .

You may customize your installation with air and lubricant filters to prolong system life, pressure gauges for monitoring, shut-
off valves to ease future maintenance and even automated filling systems to utilize bulk lubricant storage.

All of these possibilities, and more, have made Lincoln Automated Lubrication Systems the choice of industry for over 80
years.

Model 84501 Program Timer—Solid State

Designed to control the lubrication cycle frequency of air-operated single-stroke pumps.
Timer turns pump on/off at programmed intervals via a 3-way or 4-way air solenoid
valve (not included) installed in the air line to pump.

Model 85500 System Sentry II

The ultimate automated lubrication system controller/monitor now features greater
monitoring accuracy with less sensitivity to lubricant flow rates, feed line length, or
bearing back pressure. System Sentry II is always on the job, making sure that every
lube point is lubricated when it’s supposed to be.

• Solid-state controller with LCD status display and 16-button keypad for system
programming
• Controls up to two pumps with as many as two lube zones per pump
• Fully programmable monitoring and alarm functions
• Be set up to monitor every lube point for lubricant flow during each lubrication event
• Easy to understand prompts reported by simple English language messages in real
time

Some functions require optional accessories. Use a maximum of 48 sensors

and three accessory Sensor Boards (order separately—16 sensors per board) to
monitor lube points.
