ON/OFF FX
: Combine the TIME DOSING function with an ONOFF function (see section 8.10.14) for a conduc-
tivity measurement only in order to ensure prebleed of the system. Configure and activate the "ONOFF" function
before this "TIME DOSING" function so that it appears in this menu.
CMD SAFE : Confirm (select "Mode: ON") or do not confirm (select "Mode: OFF") the use of a fallback position
on the output when the "System switch" event (see section 8.10.18) has the state "ON". When use of the
fallback position is confirmed, enter a fallback position value of between 0 and 100% for each output.
• The time base is the one set in the "Date" and "Time" functions in the "Parameters" menu. See
section 8.10.1.
• When the "time dosing" function is already operational, modifying one of its parameters resets the
function.
• A new dosing cycle on the same channel cannot start until the previous dosing cycle has finished.
• Channels 1 and 2 operate independently of each other.
• When a dosing cycle is running on one of the channels, a new dosing cycle on the other channel is run
according to the following rules:
- when the current cycle is in prebleed phase, the lowest prebleed setpoint (or the highest for the
inverted hysteresis mode) "PBLIMIT" of the 2 cycles is taken into account. Moreover, the longest
prebleed duration of the 2 cycles is taken into account.
- The prebleed phase on the new dosing cycle is not run if the current cycle is in dosing or waiting
phase.
- It is only when both cycles are finished that the conductivity controller takes over.
