ALARM MENU
• Delta EC Pre-Control High: If the measured EC Pre-Control value is higher than the target value plus Delta
EC Pre-Control High, the system will generate a High EC Pre-Control Alarm.
• Emergency EC High (1 minute delay): If the measured EC is higher than the value set here for more than 1
minute, the system will be stopped. This setting should be used to protect the plants/system and should
generally be higher than the EC High Alarm based on the dosing-program target value plus the Delta EC
High.
• Emergency pH Low (1 minute delay): If the measured pH is lower than the value set here for more than 1
minute, the system will be stopped. This setting should be used to protect the plants/system and should
generally be lower than the pH Low Alarm based on the dosing-program target value minus the Delta pH Low.
7.6 EC/pH Alarm Setting
The EC/pH alarm setting table allows you to define the desired response for EC/pH related failures recognized by the
NMC-Pro:
• STOP: Stop irrigation and/or dosing for current valve (or valve group) and continue to the next valve (or valve
group).
• CONT: Continue irrigation and/or dosing for the valve (or valve group) that caused the alarm. This option
actually means that the system will generate an alarm but will not take action.
• Delay (mm:ss): Define the period the failure must be active before the NMC-Pro will generate an alarm and
will take action.
• Alarm Active: Define whether the alarm output should be triggered by the appropriate alarm.
7.7 Radio Sys. Alarm Definition

Unit type parameter SN/RF Net.

• ACTIVE: Defines if alarm is used in making decisions regarding irrigation program (YES / NO)
• INFORM: Defines if the system will notify the user of the alarm occurrence (YES / NO)
