The Knight-Trak II Laundry Management Input Board (LMIB) is an interface module which receives
wash tracking information signals from the washmachine and sends them as low-voltage signals to
the Knight-Trak II Dispenser. The module is connected to a Knight-Trak II Signal Input Board (SIB).
THE LMIB IS TO BE INSTALLED BY CERTIFIED ELECTRICAL PROFESSIONALS ONLY. The
LMIB accepts the following types of signals:
•
DOOR INTERLOCK - This signal is used to generate start and finish time stamps in the wash cycle
tracking report. Use a door switch, an light, or a track on a card reading machine. The signal only
needs to be present at the start of the wash then just before the load count pump through to the
end of the wash cycle. After the load count pump has been signalled the next time the door
interlock signal is interrupted the finish time will occur. The door interlock signal may be interrupted
before the load count pump as often as necessary.
•
STEAM - This signal is used to determining auxiliary steaming or heating of water. Steam or heat
signals are indications of additional time required to wash (many machines halt the normal wash
cycle during steaming). The steam valve or relay is the source for the steam signal.
•
DRAIN - This signal is used to count the number of drains in a given wash cycle. A drain solenoid
or a drain track on a card reading machine are typical sources for the drain signal.
•
COLD WATER - This signal is used to help track total cold water usage. Connect to the cold water
fill valve or relay.
•
HOT WATER - This signal is used to help track total hot water usage. Connect to the hot water fill
valve or relay.

(1) Inspect the wiring diagram for the laundry machine (and card reader, if required). They are
available from the manufacturer upon request. Schematic interpretation skills are a must.
(2) Measure the signal voltage between the valves, tracks, switches, or relays and signal common
(NOT case ground). Operate the washer and ensure the signals are correct and on at the right
time.
(3) BEFORE CONTINUING TO THE NEXT STEP, DISCONNECT ALL ELECTRICAL
CONNECTIONS TO THE LAUNDRY MACHINE, CARD READER, AND INJECTOR. VERIFY
THIS WITH A VOLTMETER.
(4) Install the LMIB near the SIB and connect wires from the signal sources to the LMIB. The LMIB is
equipped with signal indicator lights. When a signal of sufficient voltage and current (12-240v) is
present the light will activate.
(5) Connect the color coded LMIB wire to the LMIB wire on the SIB with grey wire nuts. LMIBs not
mounted in a plastic housing have removable barriers for interconnecting. See page 12.
(6) Housed inside the plastic module is a 1 amp fuse to protect the LMIB, SIB, and KOB. Consult the
factory if the fuse blows.
