If the digital output control is enabled, when an information will be requested to HI504901, an SMS with the digital output status will be sent. By disabling this option, it will not be possible to set the digital output status and no information SMS about the digital output will be sent. If the digital output management is disabled, the digital output will be automatically opened, even if it was previously closed. If the password is not set, only "CLOSEP" or "OPENP" SMS must be sent. SMS DELIVERY HI504901 is able to send SMSs to one (or two) cellular phone number(s). HI504901 can send two types of message: alarm SMSs (upon an alarm condition at least in one of the instruments connected to the interface) and information SMS (upon specific request from the user). To use the SMS feature, a SIM card able to make a voice call must be used. Alarm messages are submitted by HI504901 to the cellular phone number(s) when an error occurred on one of the instruments connected to the interface. A message about an alarm condition in one instrument will be sent by the interface only if the alarm is active and the specific alarm notification was enabled during last configuration, by checking the proper box on the "message option" window of the selected device (see "Interface configuration" section). If an alarm is active in one instrument connected to the interface but its notification was not enabled during last configuration, then no SMS will be sent (however HI504901 gives indication to the user about the error condition by turning on the red LED for the RS232 channel or RS485 port or digital input port where the instrument is connected). An alarm SMS can be sent only if SMS sending is user enabled through digital input terminal (#8 on page 8), otherwise no SMS will be issued. The format of alarm messages for instruments connected to the RS232 ports will be: "<INSTRUMENT NAME>; RS232-<NUMBER OF THE RS232 CHANNEL>; Alarms: <ALARM SPECIFIC TO THE INSTRUMENT>; Rem msg: <NUMBER OF REMAINING MESSAGES>" The format of alarm messages for instruments connected to the RS485 port will be: "<INSTRUMENT NAME>; RS485-<RS485 DEVICE ADDRESS>; Alarms: <ALARM SPECIFIC TO THE INSTRUMENT>; Rem msg: <NUMBER OF REMAINING MESSAGES>" During alarm condition, the field <ALARM SPECIFIC TO THE INSTRUMENT> on the alarm message will contain the list of 35 Note ALARM SMSs Default values The following table lists the default value for previous items, i. e. the factory values copy from ROM if HI504901 was never configured.

The <INSTRUMENT NAME> label is a text string correspondent to the instrument model with active alarm(s). The <NUMBER OF REMAINING MESSAGES> is a value (max. 4 digits) indicating the number of remaining messages in the SIM card (see "Interface configuration" section). Following a complete list of all available alarm indications (and their coded notations) for all devices which can communicate with HI504901 supervisor and some messages specific to HI504901 interface itself. Alarms for HI8001 and HI8002 controllers Coded notation for <INSTRUMENT NAME> label is "HI8001" or "HI8002" (depending on controller model), while coded notations for active alarms are: · "pHsensor": this alarm is triggered if the difference between the real time values of the two primary pH sensors exceed the specified maximum allowable difference. · "ECsensor": this alarm is triggered if the difference between the real time values of the two primary EC sensors exceed the specified maximum allowable difference.
