Installation
AUTOMATIC SYSTEM ACTIVATION HAZARD
Unexpected activation of the system could result in serious injury, including skin injection and amputation.
This device has an automatic timer that activates the
pump lubrication system when power is connected or
when exiting the programming function. Before you
install or remove the Lube Sentinel II Monitor from the
system, disconnect and isolate all power supplies and
relieve all pressure.
Grounding
Installation
Electrical Connections
Electrical interference from improperly installed equipment may cause erratic behavior of the device.
When installing the Sentinel II, use 18 - 24 gauge
machine tool wire (MTW). 18 gauge wire is recommended for the input power.
It is also recommended that wiring be run in its own conduit to minimize electrical interference. If the installation
is in an area of high electrical noise/interference, or in
trays with other control wiring, a shielded cable pair is
recommended.
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static
build-up or in the event of a short circuit.
Ground connections should not be connected to conduits or other electrical boxes. The ground wire should
be connected to a grounding rod or a grounded bus bar
that is tied to a grounding rod in the earth.
Shielded cable should be used on applications where
engines or heavy-duty motors are in close proximity to
the monitor, wiring or sensors. If shield cable is used,
the shield should stay intact as close to the termination
screws as possible. (Do not remove shielding from cable
if it is in a shared tray).
The shield should be connected to the designated
ground at both the sensor and the monitor.

Serial Communication
Remote communication (up to 100 feet) can be
achieved using an RS-232-type port.
Information can be read from, or written to the Sentinel II
by a personal computer (or other intelligent device). This
communication is a master/slave protocol with the Sentinel II as the slave and the PC as the master.
NOTE: With the exception of a sign-on message when
powered up, the slave will not send any data or information unless requested by the master.
• Data is sent across the serial port as ASCII characters with leading zeros suppressed.
• A BYTE can be up to 3 characters.
• An INTERGER can be up to 5 characters.
• Each command and each response is terminated
with a carriage return (CR) (ASCII - Hexadecimal
0D or Decimal 13)

Control Buttons
Operation and programming are controlled through the
use of three buttons located on the front display panel.
A RST/CLR button: In programming mode, used to reset or
clear a function
B SLCT button: In programming mode, toggles through field
options.
C PRGM button: In programming mode, used to enter
programing field.
Zone LEDs
There are three LED’s per zone for quick visual status
reporting.
D RED LED: Lites any time a zone is in fault.
E GREEN LED: Lites if a zone has its alarm active and
system is normal.
NOTE: Absence of either red or green lit LED’s indicates
that associated zone alarms are disabled.
F YELLOW LED: Echoes the cycle switch sensor status and
is lit when the switch is closed.
LCD Display - G
Displays information in one of three ways. Any of these
can be selected by pressing the SLCT button (B). The
LCD displays letter codes to identify the chosen display.
• “I” (Instantaneous): Displays the lube displacement
(over a 24 hour period) based on the time interval
between the last two cycles of the divider valve.
This time and the amount of lube delivered by one
cycle of the divider valve are factored together to
determine the 24-hour displacement.
• “A” (Average): Displays the lube displacement (over
a 24 hour period) based on the amount of time
required to complete ten cycles of the divider valve.
• “T” (Total): Displays the total amount of lubricant
that has been displaced.
The value is determined by multiplication of the
divider valve delivery by the number of times the
valve has cycled. This number is automatically
stored in memory upon completion of every ten minutes operation.

General Feature Information
General Feature Information
Tachometer
Displays actual engine/compressor shaft speed (RPM).
A flashing asterisk indicates the tachometer is enabled.
A second LCD line displays the normal target operating
speed.
An ON/OFF indication displays to indicate when alarm
monitoring is active.
It is possible to override the active alarms when the
tachometer is enabled and drive mechanism is operating a minimal speed, by pressing the RST/CLR button
until the machine accelerates to 50% of it’s normal operating speed. At that point, the alarm override ceases,
allowing proportional alarmed startup of the equipment.
Enabled alarms stay active through all ranges of input
rpm until they are manually reset after the machine has
decelerated from 50% of its normal operating speed.
NOTE: When the alarm override is active, a letter “T”
and the word “OFF” will be displayed on the LCD.
When the RST/CLR button is pushed to reset Sentinel
II, the display resets back to 0 (zero). However, if the display is in the totalized mode (identified by the letter “T”)
pressing RST/CLR resets the totals back to the last
stored value. Care should be taken when resetting a
fault to ensure that the display is not in the totalized
mode. Resetting the fault will also reset the total accumulated usage.
Fault Relay
There are three fault relays. One is used as a Power
Monitor and two are used as Zone Fault relays.
The Power Monitor Relay is a single-pole, double-throw
relay with Form C contacts. It energizes approximately 5
seconds after power is applied and stays energized as
long as power is available to the monitor. When power is
removed from the system, the relay deenergizes immediately.
Zone Fault Relays are enabled during programming.
Each Zone Fault Relay is a double-pole, double-throw
relay with two Form C contacts that change state when
their associated zone goes into fault. The Zone Fault
Relay may be programmed to either pick or drop when a
fault is detected, allowing for fail-safe operating if
desired.
A system fault TTL output is also available to annunciate
faults. It is linked with programming for relay energization settings.
Resetting Faults
Faults may be reset in several ways:
• Manually reset at the monitor by pressing the
RST/CLR button.
• Using the “Safety Set” target (see Safety Set,
page 8).
• Electrically by closing the remote reset contacts.
Zone Enable/Disable
Zones are enabled during programming. A zone may be
disabled initially by programming the zone “OFF” or by
temporarily placing an enabled zone in “BYPASS” mode
(Terminals 29, 30, 31 and 32).
Closing the contacts for “ZONE BYPASS” disables a
zone from any fault time-outs. The zone display shows
the word “BYPASS” to indicate this condition.
When the bypass has been removed, active monitoring
of the zone continues. If the alarm is enabled, the alarm
time-out will restart.
313903C 11
• Serial Port commands (see Serial Communication, page 9).
Programming the Lube Sentinel II Monitor
Cycle Switches and Other Sensor Inputs
All sensor inputs should be dry contact type. Refer to
F
IG. 6, page 7. and Technical Data, page 26.
Cycle switch TTL outputs are provided for each zone to
echo the status of the sensor input from the divider valve
or other device. The output conducts current when the
sensor contacts are open. When the sensor contacts
close, the output shuts off.
NOTE: These outputs should not be used for cycle rates
faster than one pulse per second. Output pulses may be
missed if higher cycle rates are used.
These outputs are not short-circuit protected (100mAmax). Improper connection could result in damage to
these outputs. (See Circuit Board Connections, beginning on page 4.)
Programming the Lube Sentinel II Monitor
Operation of the Lube Sentinel II is controlled through
three buttons located on the front display panel.
Buttons are labeled:
• RST/CLR - reset and/or clear
• SLCT - select
• PGRM - program
After the Lube Sentinel is programmed, it is ready for
normal operation in the monitor mode. In this mode the
Lube Sentinel II monitors the lubricant delivery and provides associated data on the LCD display.
