4. FUNCTIONING DESCRIPTION
Themeasuredorintegratedinputvalueistranslatedintoananalogoutputsignal.
The instantaneous measurement of the input is displayed. The values are also available via
ModbusRTUprotocoluponquerybyRS485bus.
4.3 Alarms on the Analog input
Four alarms may be activated on the instantaneous value of the input. Each alarm may be set
onthefollowingway:
1)Alarmontheminimumthershold. 2)Alarmonthemaximumthershold.
3)Retained Alarmontheminimumthreshold(theresetisnotautomatic).
4)RetainedAlarmonthemaximumthreshold(theresetisnotautomatic).
For each alarm, it is possible to set Threshold and Hysteresys. If the alarm is set as high, the
alarmwillturnOFFwhentheinputvalueisThreshold-Hysteresys;insteadifthe alarmissetas
low, the alarm condition will end when if the input value is Threshold+Hysteresys.The alarms
status is displayed by four leds on the frontal panel and by the relays. The relays toggle at the
alarmconditionandreturntotheinitialstatusattheend ofthealarmconditionoratthereset(if
retained). The retained alarms are reset by pressing the buttons + for someUP OK/MENÙ
seconds(onnormalviewfunctioning).
4.2 Retransmission Modalities
Theinstrumentallowsthefollowingretransmissionmodalities:
Analog Output: The measured input value is translated into an analog outputsignal (voltage
orcurrent).
4.1 Setting Modalities
All the parameters of the instrument may be set by the programming Menu or RS485. The
alarms thresholds may be quickly set by the . Besides the software hasQuick Alarm Menu
beendevelopedfortheprogrammingandtheconfigurationofthemodule(consultthewebsite
www.seneca.it).
