9. Definition of input functions
The controller is provided as standard with one input for one input function
(connection IN1). If the IF expansion card is added, the controller is expanded with
a second input for a further input function (connection IN2).
The inputs may be used alternatively for the following functions :
Water meter, Stop in service, Regeneration start, Chemicals shortage or Stop
during regeneration.
Input function IN1
Place the cursor under the required input function.
WM = water meter
SP = stop service
ST = start regeneration
CH = chemicals shortage
HO = stop regeneration
Input function IN2
Place the cursor under the required input function.
NOTE : This program step can only be selected if the controller has been fitted with
the IF expansion card.
Inputs active
You can determine whether the input contact is to be open or closed when the
function is active.
“ - “ = Contact open for activation.
“ | “ = Contact closed for activation
NOTE: Where the input is selected for a water meter its function is not
programmable as in that case the input is always active when the contact is closed.
