Input/Output Specifications

Power Requirements

+9 to +28 Volts DC @ less than 3 Amps for entire register including solenoid valves. The system can operate with either a positive or negative ground.

 

Pulse Input

+5 to +28 volt peak to peak square wave from an open collector transistor. Quadrature or single channel with a directional logic line. Frequency not to exceed 1500 Hz.

 

Scaled Pulse Output

The scaled pulse output reflects NET volume if temperature compensation is being used or GROSS volume if temperature compensation is not used. One pulse will be output per least significant digit of the display, i.e., a system set to read in 1/10 gallon will provide one pulse per 1/10 gallon (10 pulses per gallon). 150 mA sinking capability.

 

Auxiliary 1 Output and Auxiliary 2 Output

This output can be used to add features such as a pump control or additive injection.

 

Aux 1 (Out 1)

Open drain output common to the negative power input line. Sinking capability up to 1 Amp. Maximum circuit voltage is same as power supplied to LCR-II.

 

Aux 2 (Out 2)

Open drain output common to the negative power input line. Sinking capability up to 150 mA. Maximum circuit voltage is same as power supplied to LCR-II.

 

Solenoid 1 Output (Out 7)/ Solenoid 2 Output (Out 6) - Valve Control

Open drain transistor capable of sinking 2 Amps. Maximum open circuit voltage is same as power supplied to LCR-II.

 

Solenoid 3 Output (Out 8) - Optical Air Eliminator

Open drain transistor capable of sinking 1 Amp maximum. Open circuit voltage is same as power supplied to LCR-II.

 

Optical Sensor (In 5)

Three wire sensor, 0.05 Amp maximum.

 

OUT 4/OUT 5 to Remote Electronic Display

Open drain transistor capable of sinking 1 Amp. Maximum open circuit voltage is same as power supplied to LCR-II.

Pulses are active LOW.

 

RS-232 I/O Port

Meets EIA–232E standard but only incorporates five signaling lines:

 

Transmit data

Receive data

Request to Send or Data Set Ready

Clear to Send or Data Terminal Ready

Ground

 

The printer output port is compatible with the Epson™ TM 290 II, TM 295, TM 300, TMU 200D, TMU 295 printers,

Axiohm Blaster, and Okidata™ ML184 printer.

 

RS-485 I/O Port

Line terminations are SAE J1708 standard compatible which allows up to 20 units per network.

 

RTD

Four wire platinum sensor with 100 Ω resistance at 0°C and 138.5 Ω resistance at 100°C. Accuracy per IEC 751

Class B.

 

Printer (Epson Model 295)

Operating temperature: -22° to 104°F (-30° to 40°C).

 

Printer must use multi-part NCR forms and operate without a ribbon (impact image on form) to operate in the low end

of temperature range.
