Page 58: Gsm
GSM MODE If the “Type” is set to GSM, the analyzer will work with HI 504900 GSM module. This connection enables the analyzer to send SMSs to one (or two) cellular phone(s) and through this feature the device can be monitored. Moreover if an error occurs on the PCA 3x0, a SMS is sent to the cellular phone(s) signaling immediately the user about the problem. -
Page 59: Gsm Connection
One or two phone numbers associated with the service - to which the messages will be sent – must be set. The number has to be entered in the fields named “No1” and “No2”. The space reserved for a phone number is 15 digits. The phone numbers have to be inserted using the interna- tional format excluding the starting + character and without any space inside the number. -
Page 60: Setting Sms Feature
If a wrong PIN was entered three times, the user has to extract the SIM card and manually enter the PUK number using his own cellular phone to unlock the SIM card. Note: There is no need to modify the default baud rate (1200) of the serial link when enable the GSM feature. - Page 61 The phone call advises the user that something happened on the PCA analyzer and SMS is going to be received. Is not necessary to answer the phone call and it is suggested to close it without any answer. A confirmation of the alarm message reception is waited by the analyzer.
- Page 62 Note: If the analyzer is waiting for confirmation after sending an alarm SMS, the received SMS will be just stored on the SIM until the confirmation is coming or all the repeated alarm SMSs are sent. The info SMS will always contain the Chlorine, pH, ORP and Temperature readings and the Settings and Errors if enabled.
- Page 63 This particular situation is managed as an error occurrence and a confirmation of the SMS reception is waited. After that, a “GSM no credit” warning appears on the display signaling that no other SMS can be sent. In this case the user is supposed to extract the SIM card from the cellular module as soon as possible and check the re- maining credit (using its own cellular phone and calling the network operator).

Page 64: Modem Connection
MODEM CONNECTION Modem connection can be established between PCA 310-330 and a remote computer. The connection allows the user to interrogate the analyzer, from remote position, about its status and measurements and to change analyzer parameters. Also the log could be downloaded through remote connection. A SIM card able to receive data calls must be used in HI 504900 GSM module. -
Page 65: Maintenance
MAINTENANCE The PCA 310, PCA 320 and PCA 330 analyzers incorporate several technologies to minimize the maintenance. Also, if the GSM module is connected, the warnings, alarms and errors are sent to the operator, making the maintenance even simpler. The analyzer status could be sent via SMS messages after a call from operator. -
Page 66: Electrode Conditioning And Maintenance
ELECTRODE CONDITIONING AND MAINTENANCE Preparation Remove the probe protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT.

Page 68: Changing Peristaltic Pump Tubing
CHANGING PERISTALTIC PUMP TUBING It is recommended that the peristaltic pump tubes be changed on a regular basis depending on sampling period and oper- ating time. For a 5 minutes sample interval and continuous operation, changing of the tubes every month is recommended. For best results however, change the tubings every time the reagents are replaced. -
Page 69: Tubing Replacement
TUBING REPLACEMENT The remaining tubing in the analyzers should be replaced every two months. HI 70479 HI 70474 or HI 70475 HI 70473 When installing new tubing it is helpful to dip them in hot water before making the connections. It is also recommended that one tube at a time is removed and replaced. -
