b. Release the button when the pulse count is
shown on the display.
c. Press the PGRM button to advance to the
next programming option.
• Set Normal RPM: Programs the normal speed
at which the pump drive mechanism is expected
to operate.
a. Press and hold the SLCT button to increase
the RPM to a specified maximum. (See Table
2. Maximum RPM Pulses/Rev, page 17 for
limits.)
Use the RST/CLR button to decrease the
RPM’s. (The minimum selectable speed is 50
rpm.)
b. Release the button when the pulse count is
shown on the display.
Table 2. Maximum RPM for Pulses/Rev.
NOTE: The Sentinel II program allows the
machine and lubricator pump speed to vary
without causing a high or low lube fault. As the
actual measured rpm varies from the target nor-
mal rpm, the fault rate will also vary by the same
deviation percentage. The maximum deviation
from the target fault setpoints is +/- 50%.
EXAMPLE:
A drive is expected to operate at 100
rpm. The LOW FLOW rate for Zone 1 is
set to 30 pints per day. If the drive is
reduced to 75 rpm (or 75%), the LOW
FLOW fault point is adjusted down to
22.5 pints per day (also 75%). Note that
the minimum and maximum adjusted
values are +/- 50% (45 pints at 150 rpm
and 15 pints at 50 rpm).
c. Press the PGRM button. Since there are no
additional options, the display returns to the
start of the CONFIGURATION?ZONE1 selec-
tion.
3. Push the SLCT button to toggle to CONFIGURA-
TION?ZONE2.
NOTE: Pressing RST/CLR at this time exits the pro-
gramming mode and asks if the changes made should
be permanent. Use the
SLCT button to choose the
desired response and press the PRGM button to exit the
programming field and return back to the monitor mode.
Configuration?Zone2
The method of configuring Zone 2 is the same as Zone
1. If you 2 does not need to be configured, press the
SLCT button to toggle to Serial Port.
Serial Port
NOTE: If a Serial Port is not being used, press the SLCT
button to toggle to Global Settings.
To configure the Serial Port settings:
1. Press PRGM button to enter the options for the
Serial Port.
• Baud Rate: Choose one rate - 1200, 2400,
4800 and 9600.
a. Press the SLCT button to toggle between
choices.
b. When choice displays, press the PGRM but-
ton to advance to the next programming
option.
• Word Length: Permanently set to 8 bits.
Press the PGRM button to advance to the next
programming option.
