Intelli-Tank Manual (106759) 050304 – 1 – Class 1
The Intelli-Tank Driver module utilizes the 1-wire data line to receive tank level information
from a Master 4 light tank level display (C1-PN 106299 or 106296) and then mimics the
Master’s display with its high current outputs. The module also incorporates an auto-refill
function that, when activated, turns on the fill output at less than ¾ tank level and turns it off
when the tank reaches the FULL point. An alarm output activates when tank level reaches
¼ or if data from the Master is lost for over 10 seconds.
Basic parts:
Driver module C1 – PN 106877 12/24V
Installation Harness C1 – PN 106692
User Manual C1 – PN 106759
Prerequisite parts:
Master 4 light tank
level display C1 – PN 106299 12V
106292 24V
Accessories:
Remote dash indicator C! – PN 106878
Modes of Operation:
Normal The module receives tank level data from the Master and mimics the
Master’s display with the high current outputs.
Auto-Fill When the level of the tank is below ¾ the fill output comes on and remains
on until the Master display indicates FULL.
Intelli-Tank Manual (106759) 050304 – 2 – Class 1
When the unit is first powered up the lights will cycle on individually starting with the
EMPTY (output 1) light and then the lights will show the current status.
• A Module connected to a Master unit (through the 1-wire data line) will mimic the
Master unit’s LED condition and flash rate.
• A Module not connected to a Master unit will alternately flash the upper two lights and
the lower two lights. This indicates a “no data” condition.

Auto-Fill Function
Auto-fill mode is active when the auto-fill select input (pin 8) is grounded. The auto-fill
status light output (pin 2) indicates the current status of this mode and is capable of driving
positive voltage to 250mA.
Status Light Condition
On Auto-fill mode selected and is in standby
Flashing
Off
Auto-fill mode selected and is currently filling
(refill output is active).
Auto-fill mode de-selected or error condition is
present.
Intelli-Tank Manual (106759) 050304 – 3 – Class 1
The auto-fill function will energize the fill output when the tank level is at or below ¾ and deenergize when the Master display reads FULL. Auto-fill will also de-energize the fill output
and turn off the auto-fill status light if there is no data being received on the data line from
the Master display (serial error) or if a transducer error high or low (range error) is
encountered.
4 Outputs for the level lights
Four outputs are available to drive external lights to indicate tank level. These are positive
voltage outputs are capable of 7.5A each (Full light is output 4).
Alarm and alarm silence
The alarm output (pin 3) activates when the tank level falls to below ¼ tank or 10 seconds
after a data line problem exists. The alarm output is a positive voltage output capable of
250mA. The alarm silence input (pin 5) will turn the alarm off during any alarm
circumstance. The alarm silence activated by a momentary ground input.
1-wire serial interface
The 1-wire serial interface is the link between the master tank level module and any other
remote modules. If the output driver module loses the serial link all outputs will be
deactivated and then the output lights will alternate flashing the upper two lights and the
lower two lights, and the auto-fill function will be deactivated. After 10 seconds in this
serial failure condition the alarm will sound (it can be turned off with the alarm silence
switch).
Dim level light outputs
The output lights are set to the dim condition (50% duty cycle) when a ground is input on
pin 6.
Module LED indicators
There are 3 LEDs on the front of the remote driver module. The RED LED indicates that
the circuit board has power. The YELLOW LED indicates the power stud has power. The
GREEN LED indicates the condition of auto-fill mode and will react the same as the autofill stat us light output (pin 2).
