Wire #
230 VAC Lines - (metric type 24 conductor shielded cable)
YEL/GRN
Earth. This line is connected internally to the casting and must be connected to the service ground.
1
230 VAC head power hot line. If power is interrupted on this line, the head will go into standby and
power-fail modes.
2
Neutral for head power and main board authorize/authorize request circuit.

19
Authorize Output. When 230 VAC is applied to wire #20 and the handle switch is ON, 230 VAC will
be present on this line. (3 Amp. maximum load)
20
Authorize Input. Application of 230 VAC will “authorize” the MICON 500C to dispense product.
When the handle switch is turned ON, the MICON 500C applies a 14 K
Ω
capacitive reactance
between this line and wire #2 to serve as an authorize request load for Kraus Group Inc. Self-Serve
equipment. External equipment may be used to provide an authorization signal to the Micon
500LN Electronic Register provided that both units are controlled through a common circuit
breaker.
Wire #
Low Voltage Lines
9
Money Pulser Positive. This line is normally connected to the pulser power supply positive line (+30
volts maximum, DC only) and provides power to the money pulser line.
10
Money Pulser Negative (output). The MICON 500C will source a maximum of 100 mA from the
money pulser positive (#9) to this line to form a pulse once for each penny of product dispensed.
(Used with KRAUS MONITOR and MICRO consoles.)
11
Volume Pulser Negative (output). This line provides a pulse (as described above for money pulser)
for each specified fraction of a unit of volume. (Used for card or key systems.)
15
LAG Pulser Input Positive. This line is connected through a 680
Ω
resistor to the anode of an
optocoupler LED.
16
LEAD Pulser Input Positive. This line is connected through a 680
Ω
resistor to the anode of an
optocoupler LED.
17
Pulser Input Negative. This line is connected to the LED cathodes. Input voltage range for the
pulser input wires 15 & 16 is 5-20 VDC.
18
Gas Temperature Input 4-20mA.
22
Volume Pulser Positive. This line is normally connected to the pulser power supply positive line
(+30 volts maximum, DC only) and provides power to the volume pulser line.
Wire #
Data Communications Lines
12
Data Channel Common. This line is connected to the “DCC” terminal block of a Concept 5000
control box or MCIU** or to the diode board of a Micro 2RP system.
13
Talk-To-Console. This line is connected to the “TTC” terminal block of a Concept 5000 control box
or MCIU** and carries messages from the dispenser to the console.
14
Talk-To-Pump. This line is connected to the appropriate terminal on the “TTP” terminal block of a
Concept 5000 control box or MCIU** or to the diode board of a Micro 2RP system and carries
messages from the console to the dispenser.
21
RS-422 Positive Input.
