Connection of external components
Flow monitor / timer
When installed on a system where monitoring is only necessary during operating hours, the input
contact can be used for a flow monitor or a timer. This allows the time interval to be paused during
a system shutdown, thus reducing the reagent and power consumption.
A paddle can be used as a flow monitor. The potential-free contact of a timer is also possible. The
examples below show different connection options at the input contact.
When using a flow monitor, the analyses are only carried out if a defined signal is present at the
input (flow monitor reports flowing water).
Depending on the installed contact, the input can be configured as NC or NO type.
[NO] Analysis interval paused: Next analysis start is waiting for a closed input contact.
[NC] Analysis interval paused: Next analysis start is waiting for an open input contact.
(When using this function, the Sycon must be in automatic mode).
Programming: Menu > Settings > Inputs > Input 1 > Flow monitor
This function must not be confused with the function "Start analysis" by
external control.
