A short article on the operating information for your Nexus unit, including mode explanations.
The Nexus Laundry units, are automatic dosing systems designed for use with commercial washing machines. The units are intended for indoor, fixed installation only. The means of disconnection must be incorporated in the fixed wiring, with an air gap of at least 3mm in each pole. The pumps are initiated by applying signals of between 90V and 240V AC or DC across the corresponding Inputs of the A and B rails on the power board. Note: signals of between 12 v –240V AC or DC can be accepted by toggling the dip switches as shown on here – Wiring the Trigger Signals.
Used with a standard host machine. The relevant pump will operate when a Signal is present for the duration of the Signal Acceptance Time and is equal to the programmed Pulse setting. The pump will then remain static for the period of the Delay Time, before operating at the programmed speed, for the programmed run time or chemical dosage. The pump will not operate again until the unit has reset. The unit can be selected to reset after the operation of the final pump (eg. pump 4 of a 4 pump unit) or on a signal to Input 1-8.
Used with a computer controlled host machine. The pumps will operate for the duration that a signal is present across the corresponding inputs. Input 1 operates pump 1, input 2/pump 2, etc. The data management, Flush Valve and Machine Interrupt features will remain.

The pump will then remain static for the period of the delay time, before operating at the programmed speed, for the programmed Run Time or chemical Dosage. The pumps have three individual levels in which dosing can take place in each wash program and activated by the corresponding inputs. Input 1 operates pump 1, input 2/pump 2, etc.
Hot & Cold Mode
Based on the functionality of Standard Mode with the exception of only 9 programmable inputs. Input 2 & 3 combine as 1 programmable input to service a Hot and Cold solenoid connection from the wash extractor. Input 11 remains as the dedicated auto formula select input.
Auto Formula Select Mode
For Nexus units that do not have a Formula Select module. Allowing signals to be sent from the machine to the unit to lock in the desired program.
