INSTALLATION

RS232 AUXILIARY PORT

HI504901 is provided with an auxiliary RS232 port (D-Sub

9-pole female plug) for connection to a local PC using an HI920010 Hanna cable.

Note Use this RS232 auxiliary port only for local configuration of

the interface with HI504901SW software or local communication session with an instrument connected to the HI504901 interface (see “Interface Configuration” and “PC Communication” sections for details).

Note If the HI920010 Hanna cable is too short for your applica-

tion, please refer to “Appendix” for details about making a longer communication cable.

RS232 #1 AND RS232 #2 SERIAL PORT

HI504901 is provided with two serial ports (channel #1

and channel #2) for communication with Hanna HI8001 and HI8002 controllers.

Each port is a 3-pin terminal: TX, RX and GND. To connect the HI504901 interface to HI8001 or HI8002

controllers, use 9-pin D-Sub connector and shielded cable, and follow the below indications.

from 5 to 30 V is applied or when it is disconnected. This input can come from a relay contact or from an open

collector output (for example from a PLC). Connect the positive pole of an external power supply to the

positive DIG-IN terminal; connect a command relay between the negative pole of the external power supply and the negative DIG-IN (see also below diagram).

Note Never connect mains or AC voltage supply directly to the

DIG-IN terminal.

Note The digital input is optoisolated.

DISABLE SMS (DISABLE)

This input works as a digital input (see previous subsection) and allows to ignore active errors and suspend SMS sending during operations as calibration, start-up, maintenance, etc.

DIGITAL OUTPUT (DIG OUT)

This optoisolated terminal is an open collector output, which can be used for external signaling through LED indicators or small relays (see below diagram).

Note The RS232 standard allows to connect only one instrument to

each serial port.

HI504901 is provided with a digital input, which can be configured with HI504901SW software (see “Interface Configuration” section) to send an alarm SMS when a DC voltage

RS485 SERIAL PORT

HI504901 is also provided with a 2-pin RS485 terminal for communication with Hanna HI23, HI24, HI700, HI710, HI504 meters series and HI504910 digital transmitter.

The RS485 standard is a digital transmission method that allows long line connections. Its current loop system makes this standard suitable for data transmission in noisy environments.

Specifications:

The RS485 standard is implemented in HI504901 interface with the following characteristic: Data rate: up to 9600 (selected while configuring the

interface through HI504901SW software) Communication: bidirectional Half-Duplex Line length: up to 1.2 Km typical, with 24 AWG cable Loads: up to 32 typical Internal termination: none

Connections:

The connections for the provided 2-pin RS485 terminal are as shown on the below diagram. The instrument has no internal line termination: to terminate the line an external resistor equal to the characteristic line impedance (typically 120 Ω) must be added at both line ends. HI504901 RS485 port can connect up to 32 instruments on the same physical network, with a total line length up to 1.2 Km using a 24 AWG cable.

POWER SUPPLY INPUT

Use a 12VDC adapter (HI710005 or HI710006) and connect the black wire to

the positive input terminal (marked “+”) and the black & white wire to the negative one (marked “-”).

All hard wiring can be accomplished through five watertight cable glands on the bottom side of the case, by passing wires through the rubber grommets and tightening the nuts.

Note All connected cables should end with cable lugs.

BATTERY

All the instruments connected to the RS485 port are “slave” devices that are queried by the HI504901 supervisor. In other words, the interface can work only as a “master” component, whereas the connected instruments work as remote terminal equipments answering to the commands only. Each instrument (except the HI504901 interface itself) is identified by its Process ID number, included within the 00 to 99 interval, which corresponds to the Process ID configured through the proper setup item (please refer to the instrument instruction manual for a complete explanation).

Note If an instrument does not recognize the address within the

command string, then it discard all the following bytes.

As additional feature, the HI504901 interface is also provided with internal Fail Safe Open Line protection method.

To minimize electromagnetic interferences, it is recommended to use shielded and twisted pair cable to connect the units.

FOR SAVING BATTERY, THE HI504901 IS SUPPLIED WITH BATTERY NOT CONNECTED.

PLUG THE BATTERY CONNECTOR BEFORE STARTING OPERATION.

Use only rechargeable sealed lead-acid battery with 12 V and 0.8 Ah capability.

To substitute battery, please follow below instructions:

1. turn off the HI504901: turn OFF the power switch and disconnect the interface from the mains;

2. remove the screws on the bottom of the two battery clips;

3. disconnect the battery cable from its connector;

4. substitute the old battery with a new one;

5. fix back the two girdles by tightening the screws;

the battery connector, otherwise an alarm SMS will be sent immediately after the start-up procedure (see “Fault Condition” section for details).

stitution, it is possible that an alarm SMS of “Battery failure” is sent. Ignore that message and check if the error is still active the day after. For avoiding this problem, connect the unit to the mains and wait for at least 10 hours before turning ON the power switch. In this manner the new battery can be charged.

Before using the HI504901, insert a SIM card.

• Press the SIM card holder ejector on the cellular module by using a sharp item (for example, a pen);

• Insert the SIM card in the holder and push it back in the housing.

Note If the HI504901 has to be used for sending alarm SMS, be

sure that the SIM card can support voice calls. If the HI504901 will be used for remote connection session, be sure that the SIM card supports data calls. Please contact the cellular network operator for information about SIM active services.

Note Do not remove the SIM card while voltage is applied to cel-

lular phone. Before removing the card, turn off the interface. Failure to do so may seriously affect the serviceability of the HI504901.

START-UP

IDLE STATE

Turn ON the power switch (#14 on page 8): the red SMS disable LED lights up and will stay in this state until the start-up procedure ended and the idle mode is entered.

During start-up procedure the Real Time Clock (RTC) is checked to control if a reset occurred since last software initialization. In this case, the RTC is initialized with the default date and time 01/01/2000 - 00:00. An EEPROM reset does not affect the RTC settings.

The EEPROM is also checked to control if it is new. In this case, the default values are copied from ROM and the device enters normal mode. Otherwise an EEPROM checksum test is performed (the same is performed periodically during EEPROM selftest procedure, see “Fault Condition and Selftest Procedure” section for more details).

If checksum is not correct, the proper EEPROM error LED indication will be given as soon as the Idle state is entered.

During start-up, the internal cellular phone is turned ON and an initialization procedure is performed to insert PIN code (when needed) and make network registration for enabling incoming and outcoming calls. Moreover, the telephone answering service is disabled to avoid automatic network call forwarding if interface is busy and can not serve immediately incoming call.

Initialization procedure can last up to 30 seconds if no problem occurs, otherwise some more time could be needed and proper cellular LED indication will be given in idle state.

When the start-up procedure is complete, the interface enters the idle state.

Note When the HI504901 is turned ON for the first time, it is

possible to get a cellular error indication. This can happen if the SIM card requests a PIN code to be registered in the network and the interface was not yet configured (see “Local configuration” section for details).

The idle state is the normal operation state for the HI504901 supervisor. While in idle state, the following main tasks are fulfilled:

• Management of incoming remote connection and configuration requests (see “Interface configuration” and “PC communication” sections for details);

• Management of incoming local connection and configuration requests;

• Polling procedure of connected devices;

• Diagnostic selftest procedures: battery test, cellular phone test, EEPROM corruption data test (see “Fault condition” and “SMS delivery” sections);

• Processing of incoming SMS’s for digital output control (if enabled) and information SMS’s request (see “SMS delivery” section);

• Sending of alarm SMS’s or information SMS’s upon user request (see “SMS delivery” section).

When in idle state, the HI504901 can perform periodically some diagnostic selftest procedures as: internal backup battery test, cellular phone test, EEPROM corruption data test. If one of these tests does not pass, the interface advises the user with a visual indication about the problem using the red and green SMS enable/disable LED’s. Please refer to “Fault conditions and Selftest Procedures” section for more complete indications about interface related fault conditions.

Moreover, every 30 seconds the two green LED’s for cellular phone signal are updated with the current signal strength, and the indication meanings are listed in the table below:

LED Status Meaning

Cell Signal 1 (green) OFF No signal or Cell Signal 2 (green) OFF cellular error found

Cell Signal 1 (green) ON Medium signal Cell Signal 2 (green) OFF

Cell Signal 1 (green) ON Strong signal Cell Signal 2 (green) ON

1918

Also the digital output status LED is updated with the current status of the digital output contact. The digital output contact status can be changed by the user only by sending the proper SMS to the interface. The below table shows the digital output LED indication depending on the digital output status:

LED Status Meaning

Digital Output OF F Dig.output contact open (yellow) ON Dig.output contact closed

Note The status of the digital output contact is saved in HI504901

internal memory, so that the digital output is set to the correct value in case of a reset or after a start-up of the interface.

During polling procedure all devices connected to the interface through RS232, RS485 serial ports and digital input port (if correctly configured, see “Interface Configuration” section) are periodically queried to acquire their current status, measurement values and active alarms. The delay between a query operation and the following one is user selectable, and can vary from 1 to 10 minutes (see “Query Delay” field and “Interface Configuration” section). If many devices are connected to the RS485 link and the cellular phone interface can not interrogate all the devices within the selected delay time, then the actual interval becomes longer than the set value. When polling devices procedure is completed, if some alarm is active on the device connected to an RS232 port channel, the corresponding LED (#1 and #2 on page 9) will light up; besides, the RS485 serial port LED (#3 on page 9) lights up if an alarm is active at least in one of the instruments connected to the RS485 port (up to 32 devices can be connected on the same RS485 port); the digital input port LED turns on or off depending on the user-selected logic for closed contact (if control of digital input port was user-enabled during last interface configuration). Moreover, if an active alarm found in a device connected to the HI504901 matches with one of those selected by the user during last interface configuration, or if the digital input status matches with the condition selected for triggering an alarm message, then one (or more) SMS(s) are immediately submitted by the HI504901 to the set cellular phone number(s) (see SMS delivery” section).

Note The “Query Delay” time value fixes the maximum delay be-

tween an alarm occurrence in a device and the related alarm SMS sending by the interface.

SMS can be submitted by the HI504901 supervisor only if the SMS sending feature is enabled through an external switch (see further on for details); if the SMS sending is disabled, then no message will be sent upon alarm or fault condition on connected devices.

Note To make the HI504901 queries the connected devices and

sends SMS’s, it is necessary to configure the interface, otherwise no polling procedure can take place and no alarm notification will be given by the interface. HI504901 can not automatically detect which instruments are connected to the interface; moreover, the user must select for which type of alarms he wants to receive warning SMS’s.

While in idle state, the SMS sending feature can be disabled or enabled by the user at any time, by simply closing (or opening) the proper external switch. If no error indication is already active, then the red and green LED’s (# 5 and #6 on page 9) keep indication about the SMS sending enable/ disable status:

External Switch LED Status Meaning

Open SMS enable (green) ON SMS sending enabled

SMS disable (red) OFF

Close SMS enable (green) OFF SMS sending disabled

SMS disable (red) ON

Note Sometimes the updating of LED indication about SMS send-

ing status can take a few seconds after changing the external switch status by the user. This happens if the interface is busy while performing procedures as polling devices, SMS sending, incoming call processing, etc.

While in idle state, HI504901 can serve also incoming request for configuration or PC communication session activation (both local and remote), but remote sessions (both configuration and PC communication) can take place only if no cellular errors are active on the interface.
