Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama- tion 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.
When installing the Sentinel II, use 18 - 24 gauge when exiting the programming function. Before you machine tool wire (MTW). 18 gauge wire is recom- install or remove the Lube Sentinel II Monitor from the mended for the input power. system, disconnect and isolate all power supplies and relieve all pressure.
Circuit Board Connections . 1 - F . 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.

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 ener- gized as long as power supply voltage is active (F .

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 Table 1: Serial Pin Data Remote communication (up to 100 feet) can be achieved using an RS-232-type port. Pin # Description DB-9F DB-25F Signal Ground Information can be read from, or written to the Sentinel II by a personal computer (or other intelligent device).

Component Identification Component Identification . 10 Control Buttons LCD Display - G Operation and programming are controlled through the Displays information in one of three ways. Any of these use of three buttons located on the front display panel. 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). There are three fault relays. One is used as a Power A flashing asterisk indicates the tachometer is enabled. Monitor and two are used as Zone Fault relays. A second LCD line displays the normal target operating The Power Monitor Relay is a single-pole, double-throw speed.
When the sensor contacts close, the output shuts off. Programming the Lube Sentinel II Monitor Programming Overview Operation of the Lube Sentinel II is controlled through three buttons located on the front display panel.
