Programming the Lube Sentinel II Monitor
12 313903B
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 dam-
age 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 pro-
vides associated data on the LCD display.
Programming Overview
NOTE: The following Programming Overview instruc-
tions are provided as a quick guide, only. Detailed,
Step-By-Step Programming instructions are provided on
page 14.
Entering Data
There are four main selections within the programming
field:
• Configuration? Zone 1: Sets Zone 1 parameters
• Configuration? Zone 2: Sets Zone 2 parameters
• Serial Port: Sets parameters for serial communica-
tions to PC
• Global Settings: Specifies how the monitor reacts
to faults and how relays are energized or deener-
