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 reects NET volume if temperature
compensation is being used or GROSS volume if
temperature compensation is not used. One pulse will be
output per least signicant 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 ve
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.
