Monitoring while the water softener is in regeneration may erroneously indicate
hardness leakage. An attempt to monitor with the water feed stopped would
return either hardness leakage in stagnant water in the plumbing or a system
error due to a lack of flow.
The limit analyser provides the following two methods, which may be used
alternatively, to avoid false alarms:
Utilizing the remote input-signal feature
Connection the external contact with no-voltage!
e.g. → flow control switch
→ level control switch
may allow SYCON 2500 monitoring only while the water softener is turned on
and water flows respectively, or to suspend monitoring while the water softener is
in regeneration.
The purpose of remote signals is to prevent a monitoring while the water softener
is regenerating or the feed water is stopped.
Utilizing an external timer
Monitor start time and monitor stop time may be set by an external timer. A no-
voltage timer-output can be connected to the remote-signal input of the Sycon
2500 terminal block.
It is recommended to connect a remote signal wherever possible to prevent
false detections and avoid recovery operations.
If only remote regeneration signal from water softer is connected, a false
detection of hardness leakage may result from monitoring the stagnant water
while the water is stopped, or a system error may occur due to the lack of flow.
Connect only no-voltage inputs on terminal block 13 + 14
If no remote signal is connected, be sure to close contact terminals 13+14
If IN-contact is open no monitoring will occur with the exception of manual
monitorings.
