See Technical Data, page 26 for model information, including power requirements.
Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING ELECTRIC SHOCK HAZARD This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock.
Installation Installation Electrical Connections 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.
Installation Circuit Board Connections (FIG. 1 - FIG. 7 show the circuit board and power connections necessary to install the Lube Sentinel II Monitor in your lubrication system.) All electrical connections are made to terminals along both sides and the bottom of the main circuit board, except for serial communications. Serial communication connections are made via a special plug-in header block. External Connection Terminals FIG.
Installation Terminal Strip Right Side Power Connections Terminals 1&2 Power Connection 115/230 VAC power input terminals (polarity insensitive) 3 Earth Ground 4 +24 VDC Input 5 0 VDC Input 6 +24 VDC Out (for sensor use) 7 0 VDC Out (for sensor use) 8 0 VDC Out (for sensor use) FIG. 2 Terminal Strip Bottom - Fault Relay Connections Terminals 9 - 14, Zone 1 Fault Relay: The zone fault relay is a double-pole, double-throw (DPDT), Form-C relay.
Installation Terminals 15 - 20, Zone 2 Fault Relay: Relay data for Zone 2 is the same as for Zone 1. Pole “A” (for Zone 2) uses terminals 15 (nc), 16 (com) and 17 (no). Pole “B” (for Zone 2) uses terminals 18 (nc), 19 (com) and 20 (no). (See FIG. 4.) Ignition Shutdown External Flow/No Flow Lights Magneto Grounding Energize External Load (relay coil, etc.) FIG. 4: Wiring Examples when Zone 1 and Zone 2 are used.
Installation Terminals 21 - 23, Power Failure Relay: The power-fail relay is a single-pole, single-throw (SPST) relay rated for 0.5 ampere at 125 VAC or 1.0 ampere at 30 VDC. Terminals are to Form “C” contacts: 21 (nc), 22 (com) and 23 (no). This relay will be energized as long as power supply voltage is active (FIG. 5). FIG.
Installation Terminal Strip Left Side TOP Open Collector Outputs These outputs are open collector, floating TTL outputs. There are no protection devices on these drivers. If the transistor output is connected directly to +24 volts with no load, these devices may be damaged. These drivers are optically isolated from the local power supply and their commons are floating.
Installation 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.
Component Identification Component Identification G D D E E F F A C B FIG. 10 Control Buttons LCD Display - G Operation and programming are controlled through the use of three buttons located on the front display panel. 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.
General Feature Information General Feature Information Tachometer Fault Relay Displays actual engine/compressor shaft speed (RPM). A flashing asterisk indicates the tachometer is enabled. There are three fault relays. One is used as a Power Monitor and two are used as Zone Fault relays. A second LCD line displays the normal target operating speed. The Power Monitor Relay is a single-pole, double-throw relay with Form C contacts.
Programming the Lube Sentinel II Monitor Cycle Switches and Other Sensor Inputs All sensor inputs should be dry contact type. Refer to FIG. 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.
Programming the Lube Sentinel II Monitor Press PRGM button to enter programming field. 1 RST/CLR SLCT PRGM RST/CLR SLCT PRGM Press SLCT button to toggle between four fields.
Step-By-Step Programming Instructions Step-By-Step Programming Instructions The following instructions are listed in order of appearance. To bypass a selection, press the SLCT button until the desired selection displays. • This input is necessary for calibrating the Sentinel II for the lubricant volume required for one cycle of the divider valve assembly. Configuration?Zone1 1. Press PRGM button to enter the programming mode. To determine this number: a.
Step-By-Step Programming Instructions e. Press and hold the SLCT button to increase the value until the Port Total from step d, (page 14) displays. (9999 is the maximum amount allowed in this field.) Use the RST/CLR button to decrease the value. • Low Flow Set: Appears if LOW FLOW or HI and LOW FLOW is selected. (If HIGH FLOW only was selected, skip to the HIGH FLOW SET section.) The alarm is based on the minimum usage rate (Low Flow) per 24 hours.
Step-By-Step Programming Instructions • a. Press the SLCT button to toggle between choices. High Flow Set: Appears if HIGH FLOW or HI and LOW FLOW is selected. (If LOW FLOW only was selected, skip to the ENABLE TACH section.) If the tachometer is not to be enabled, select NO. No further options will be asked for the zone. The alarm is based on the maximum usage rate (High Flow) per 24 hours.
Step-By-Step Programming Instructions 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). 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.
Step-By-Step Programming Instructions • Stop Bits: Choose one: 1 or 2 bits. a. Press the SLCT button to toggle between choices. b. When choice displays, press the PGRM button to advance to the next programming option. • • Invert Relays (fault relay logic): Allows selection of whether the zone fault relays and the TTL output will energize or deenergize when a fault is registered. Choose either YES or NO: a. Press the SLCT button to toggle between choices. Parity: Choose one: ODD, EVEN and SELECT. a.
Step-By-Step Programming Instructions 4. Press the PGRM button. When the Sentinel II returns to the monitor mode and updated with the new, saved changes. NOTE: • Pressing any other button, or leaving the response set to NO, erases and does NOT save changes. Sentinel II returns to the original setup configuration. • Once the changes have been saved, pressing RST/CLR button will not undo the new setup configuration.
