b. Release the button when the pulse count is
shown on the display.

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.

button to choose the
desired response and press the
PRGM
button to exit the
programming field and return back to the monitor mode.
