Limit Violation Monitoring/Alarms
AdEM®-PTZ
firmware has been designed to monitor the set-point limit (except Low Battery) violations of the
following parameters:
• Low/High Pressure
• Low/High Temperature
• Low/High Flowrate
• Memory Error
Low and High set-points for Pressure, Temperature and Flowrate can be set using RometLink software. Low and
High set-points for Flowrate are also set automatically when the meter size changed (0% and 105% of Qmax).
Every wakeup the AdEM®-PTZ will check the EEPROM, the Memory Error will be set when an EERPOM reading is
corrupt, and this alarm is cleared automatically if the reading is correct.
Whenever limit is violated, warning condition is generated, and 3 dots will show on NORMAL DISPLAY.
Also, an alarm message will be displayed as the first item/s in CUSTOM DISPLAY whenever CUSTOM DISPLAY is
accessed.
“LO T ALM” - for Low Temperature Alarm
“HI T ALM” - for High Temperature Alarm
“LO P ALM” - for Low Pressure Alarm
“HI P ALM” - for High Pressure Alarm
“LOW FLW” - for Low Flow Alarm
“HIGH FLW” - for High Flow Alarm
“MEM ERR” - for Memory Error Alarm
Warning message will be cleared automatically when the parameter comes into normal range.
However, these limit violation occurrences are recorded in the Alarm Logger (except Memory Error).
Alarms data can be downloaded by RometLink software for investigation and export to Excel.
