GENERAL INFORMATION
OPERATION
The Nexus Laundry units, are automatic dosing systems designed for use with commercial washing machines. The
units are intended for indoor, xed installation only. The means of disconnection must be incorporated in the xed
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
12V and 240V AC or DC can be accepted by toggling the dip switches as shown on Page 9.
STANDARD MODE
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 nal
pump(eg. pump 4 of a 4 pump unit) or on a signal to input 8.
RELAY MODE
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, ush valve and
machine interrupt features will remain.
LEVELS MODE
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 pumps have three individual levels in which dosing can take place in each wash program and activat-
ed by the corresponding inputs. Input 1 operates pump 1, input 2/pump 2, etc.
