High 28 V dc INTRODUCTION Your OMEGA DPClO-TL is an UP counting totalizer with a high-contrast eight-digit LCD display. The front-panel reset key can be disabled. A remote-reset terminal is provided. FRONT VIEW Plastic front panel sealed to 8digit LCD meet Display NEMA 4X REAR VIEW Ir AST 4 Ml Reset APPLICATIONS This totalizer is intended for simple totalizing applications. One count input pulse per item is necessary. The only decisions to be made are: 1. Do you use the high or low speed input? 2. Do you want the front panel reset button active? OPERATION The totalizer display has lead-zero blanking. No decimal point is available. MOUNTING Gasket Installed? IffflJ Separate contact and solid state count inputs are provided. The solid state input (terminal 3) requires a current-sourcing sensor and can count up to 10 kHz. Inputs into this terminal are counted on the positive-going edge. Count occurs on this edge of the pulse(Voltage applied to terminal) / rl Terminal 3 is pulled down to common. When a sensor output supplies voltage to this terminal, one count is registered on the display. The sourcing signal must supply at least +2.0 V dc but no more than +28 V dc. Note: When a sourcing signal is applied to terminal 3, a power assist feature of the DPClO-TL extends the life of the battery. Terminal 2 is the low-speed, current-sinking count input designed to be used with a contact closure to ground. It has a maximum count speed of 20 Hz. Inputs into this terminal are counted on the negative-going edge. Contact Closes Contact Opens $gjiijjqr Terminal 2 is pulled up to +3 V dc. When a contact closes, pulling the voltage down to .4 V dc or less, one count is registered. RUN MODE Screens The totalizer screen is the only screen available on this model. Front Panel Reset Enable 1 5 Enable/R GNDl t t( Note: The front-panel reset button comes disabled from the factory. To enable the button, install a jumper wire from terminal 5 to ground, terminal 1. Note: The reset terminal on the rear panel is still active when the front reset button is disabled. PROGRAM MODE There is no program mode for this model. Page 2 WIRING RECOMMENDATIONS Following these suggestions will increase noise immunity and extend the life of the product. Cable: Make the connection between the count source and the totalizer with a two-conductor shielded cable. Connect the shield to earth ground at one end only. Relay Coil Suppression: If a relay contact is used as a count source, suppress the relay coil. This can be accomplished with an RC network for AC coils or a diode for DC coils. Mounting: Do not mount he totalizer nearasolenoidorother inductive devices. Supply enough ventilation to keep the totalizer operating within the temperature specifications. BATTERYSAFETY The lithium battery that powers your device contains inflammable materials such as lithium organic solvent, and other chemical ingredients. Explosion or fire may result if the battery is not handled correctly. To avoid an accident follow these guidelines: ?• Do not stack or jumble up batteries ?• Do not heat batteries above 95°C ?• Do not disassemble batteries ?• Do not recharge lithium batteries ?• Do not apply pressure to, or deform batteries ?• Do not solder to batteries ?• Do not dispose of batteries in fire ?• Insert battery with correct polarity Terminal Function Operation 1 Ground 2 Input B Use with Contact Closure to Ground Count Input Maximum 20 Hz Count Speed 3 Input A Use with Current Sourcing Sensor Count Input kHz Count Speed maximum 10 4 Reset Connect to ground to Reset Totalizer.
