TECHNICAL DOCUMENT The Oilgear COMPARATOR MODULE contains 5 sep- arate comparator sections. Each individual section can be used to determine if a dc input voltage (Vin) is greater than or less than a predetermined set point voltage (VSct). The COMPARATOR MODULE consists of five input • Part number L404887-100 has five (5) positive input • Part number L404887-101 has three (3) positive and two (2) negative input channels. The COMPARATOR MODULE is used to compare the value of an input voltage with a predetermined setpoint voltage (Vset). The setpoint voltage level is adjusted by a twenty (20)...

TECHNICAL DOCUMENT Specifications for the COMPARATOR MODULE are Setup and calibration for the COMPARATOR MODULE shall be performed as follows. 1. With all power to rack removed, attach extender card to COMPARATOR MODULE and install into appropriate Input voltages on both positive and negative channels can range from +10vdcto-10vdc. On a positive input channel, any input voltage that is more positive than the setpoint voltage will enable the output. On a negative input chan- nel, any input voltage that is more negative than the setpoint voltage will enable the output. Other combina- tions...

TECHNICAL DOCUMENT 2. Apply known input voltage to COMPARATOR MOD- 3. While monitoring ON/OFF state of LED indicator (2, figure 1-1), rotate set point potentiometer (1, figure 1-1) until desired ON/OFF state is obtained. An LED on indicaton is representative of a logic change output not a power transistor output change or function. A change in LED intensity may be an indication of rapid output cycling. 4. Adjust corresponding hysteresis adjustment potentiom- eter (3, figure 1-1) located through side cover of module to avoid toggle action about set point. 5. Remove all power to rack. 6....
