The new MPL-1000 PLUS is designed to meet today’s laundry chemical injection needs with economy and greater 
flexibility in mind. Through advanced microprocessor technology, the MPL-1000 PLUS is one of Knight Equipment’s 
least expensive laundry injectors, yet has all of the required features to meet every type of washroom condition. The 
MPL-1000 PLUS can run up to 6 pump outputs in any one of three different modes; SIGNAL, SEQUENCE, and 
RELAY mode. L.E.D indicators let the user know whether they are programming in SIGNAL or SEQUENCE mode, 
what is being programmed, the mode the MPL-1000 PLUS is running in, and which pump is being signaled. The 
MPL-1000 PLUS has dual formula capability for light or heavy soil conditions for each pump, with separately 
programmable delay times for each formula. Innovative use of delay times allows calibration to be a one-man job. All 
programmed times are stored in a non-volatile memory which cannot be altered by voltage spikes or power outages. 
All signal inputs have independent signal and common connections, allowing multi-washer connections to one circuit 
board. The signal input circuitry will accept and verify a signal anywhere between 18 to 240 volts (AC or DC). 

When connecting signal wires to the MPL-1000 PLUS, always check the schematic of the washmachine. If in doubt 
about the installation, please contact your nearest authorized Knight representative or contact the machine 
manufacturer at the number listed below.

VOLTAGE INFORMATION 

Main input power voltages are determined by use of “jumpers” near the power transformer: 

               For 120v AC, jumpers are placed on JP17 and JP19 only. 
               For 240v AC, jumpers are placed on JP18 and “Spare Jumper” only. 

Be sure that this voltage matches the intended main power voltage. The voltage selected by the jumpers MUST 
MATCH the pump motor voltage and should NOT BE TOUCHED if the MPL-1000 PLUS is received as a new item.
