SECTION 1 - INTRODUCTION

1.1 GENERAL DESCRIPTION FUNCTIONALITY SMART S-500 is a State of the Art universal Combustible and Toxic Gas Detectors, a reliable, continuous monitoring device to protect people and your high value investments. SMART S-500 Gas Detector employs a powerful RISC Microprocessor which provides self diagnostic, serial line communications RS-485 for MODBUS protocol, One-Man calibration features firmware resident. SMART S-500 Gas Detector is suitable to be employed with almost all gas sensing elements / electrochemical cell available in the market. SMART S-500 Gas Detector employs a unique highly coupled Pellistor beads, or Electrochemical Cell, sensing elements supported by a plug-in cards. Sensors are field replaceable protected in a S.S.316 housing ATEX certified. The electronics enclosure is light alloy epoxy red painted ATEX certified. SMART S-500 technology has been developed to offer long life durable and strength device to protect your plant and to provides high reliability with easy and low cost maintenance. SMART S-500 HC transmitter represents a technological innovation in the combustible gas detection field. The electronics based on a microprocessor RISC, that visualizes on digital display 16 characters the gas concentration value, verify constantly power value of each single circuit any possible Fault as short circuit or Pellistor open. A Watch-Dog, circuit check the correct working of the analogue and digital logic sections. Any working anomaly are visualized on a digital display and by a fault relay, on terminal boards. SMART S-500 HC has a proportional output related to the concentration detected that can be interfaced directly to a PLC/DCS or to a generic system which receive 4÷20mA signal. (1÷22mA for calibration and diagnostic) It is possible to set the value of Warning and Alarm. The signals are visualized by the display with “Warning” and “Alarm”, along with “Fault”. These indications are available as free voltage contacts on the interface terminal board. In case of large leak of gas to be measured, the Over-range indication will be displayed.

The firmware has been made to guide the operator, helping him for a simple and accurate calibration and maintenance. One point of calibration, equal to about 50% of measure field, will be enough to obtain a correct calibration.

An exclusive mode of remote calibration (also via serial interface) is available and allows the SMART DETECTOR S-500 to receive an external command, when the Zero calibration starts and to control automatically the cylinder solenoid valve (open-close), with sample gas, for “Span” calibration. Through the serial line full duplex 485 standard RTU MODBUS, it is possible to set and adjust the analogue value corresponding to the gas concentration read by the sensors as well as all sensor functional parameters.



1.2 DETECTOR To wire the sensor SMART S500 Terminals it is necessary to unscrew the Allen locking screw, remove the upper glass cap and repeat the operation for the central part of the explosion proof housing. Then take out the circuit leave it up making sure that interconnecting cable remain in its own position, then operate on terminals screws related to this connection. Also terminal screw must be pulling out in order to simplify the wiring connections. Particular attention must be used during operation of screwing up the central glass cap in order to avoid any damage. In order to follow state of the art related to explosion proof area rules it is necessary to lock all parts using the blocking screw above mentioned (See section 9.1). fig. 1 fig. 2

fig. 3



1.3 SENSOR S-500 HC sensor has been designed with an innovative technology that permit to increase the reliability of detection, to reduce maintenance costs and fast sensor replacement in case of damages or fault. S 500 HC sensing element is made by two high temperature matched Pellistor beads. The beads are mounted on Teflon support to insulate them from external temperature change. The printed circuit with Pellistor beads is located in a S.S.316 INOX-316-L environmental resistant to aggressive agents. Sensor’s body is physically separated from electronics or terminal enclosure by an epoxy resin Flame Resistant. The sensor is made by two mechanical parts a sensor body base and sensor coverage separable on field, this permit the Pellistor beads replacement directly on the field without disconnecting power on electronics detector.



1.4 REPLEACEMENT

S-500 SENSING ELEMENT Design represent a real cost of maintenance reduction, giving the possibility to substitute the sensing elements in few minutes. . The SMART S-500 Software permits to locally disconnect the sensor only, using a specific command from the keyboard , the sensor assembly can be open in classified area simply unscrewing the mechanical protection and substitute the sensing element mounted on the plug-in circuit. Most of other detection system in the market require the complete shut-off of the detector and replacement of the complete sensor and off site service condition, for the area involved.

For HC and TX versions the Warning relay K1W and Alarm K2A will remain activated and on serial line will be available the related information (status of Warning, Alarm, Over range, analogical value, etc.). For OXY version only on serial line the information will be available for Over-range and analogue value. In this situation for HC version when the detector will reached Over range the power supply to the Pellistor sensor will be removed in order to protect its integrity, and each 30 seconds the sensor will be powered to verify the gas concentration value in the ambient, if the Over-range condition continues, the Pellistor will be turned off again and again. When the concentration value result lower than the full scale, the Pellistor will remain powered normally and the display will show the alarm condition and relative measure of value concentration. Available data on serial line will be adjourned consequently. When the concentration value will go down alarm condition the relative relay K2A will be deactivated and the display will show the pre-alarm condition and the relative measure of value concentration. When the ambient gas concentration decreases, down pre-alarm the relay K1W will be deactivated and the display will show the measure of value concentration. When any fault arrives to the system, the relay K3F will be deactivated and the output current will be 1mA. The display will show these messages:

SECTION 5 – CALIBRATION PROCEDURES

5.1 LOCAL CALIBRATION Caution: If you don’t have know gas concentration or not enough gas , don’t try to start calibration.

Place the magnet on “MENU” symbol the display will show: FUNCTION

SET UP

Place the magnet on decrease symbol until you read FUNCTION CALIBRATION. The display will show the following scroll message:

FUNCTION CALIBRATION

• Verify to be in free air from HC or toxic gases. • Prepare calibration kit with Nitrogen for OXY version.

Place the magnet on “ENTER” symbol this will confirm start calibration . In calibration condition the output current will be set at 2mA and all output function will be inhibited. The MODBUS on the serial line (IN-CALIB.) first function will be activated. Caution: If you don’t have know gas concentration or not enough place the magnet on “MENU” symbol two (2) time to exit of procedures. If you continue the display will show the following message describe the concentration calibration value, modify through increase or decrease symbols till you set the concentration calibrating gas that will used (written on the bottle in % L.E.L. or in ppm ):

• This function is not available for OXY version. TEST GAS

C = 50.0

Place the magnet on “ENTER” symbol this will proceed with calibration . • Apply nitrogen with flow of ¼ or ½ litre/minute (OXY version).

The instrument will make the Zero value calibration visualizing the following message: For HC & TX For OXY

ZERO IN PLEASE NITROGEN PROGRESS APPLY

When “ZERO” calibration is terminated, the following message will be visualized: ZERO

OK • Remove Nitrogen of Sensor (OXY version).

After zero has been verified or adjusted the procedure will go to “SPAN” calibration. The display will show:

For HC, TX OXY For HC, TX For OXY PLEASE TEST OXYGEN APPLY GAS 20.9 %V

Use the calibration kit device supplied by SES ASA ENGINEERING S.r.L., 0,5BAR cylinder with calibrating gas 50% L.E.L or 50% of Full Scale for ppm Toxic Gas with flow meter and



valve to adjust the flow at ¼ or ½ liter/minute of selected gas. As soon as the concentration is passing 35% L.E.L. / ppm the digital display will show:

• Verify to be in free air for OXY version, or apply Oxygen at 20,9% vol.

SPAN IN PROGRESS

To complete the “SPAN” phase, the display will show the message of calibration completed, followed by the message that invite to remove the sample gas.

• The OXY version will show only the message CALIBRATION COMPLETE and then will exit automatically from this procedure.

CALIBRATION

COMPLETE PLEASE REMOVE

TEST GAS When the gas concentration will go down 30% of FS value, the message of calibration completed will be alternative to the message of waiting to return to zero value.

CALIBRATION COMPLETE

When the Zero value of the instrument will return to normal operative functions, actuating the output relay, setting the value of output current and showing the value of concentration detected.

5.2 REMOTE AUTOMATIC CALIBRATION The calibration procedure can be started remotely (when the remote calibration system as described in sez.4.7 is connected.) the calibration gas solenoid valve can be energized in two ways

• By the closing (to 0 VDC) of the input IC-0V on the connector J2 (on CS5) of the terminal board of the instrument.

• Through the setting of MODBUS variable (IN_CALIB.) through serial communication line RS-485 to actuate the remote Solenoid valve.

When actuated this function will be start the same sequence of calibration described in the previous section at paragraph 5.1. When Span Calibration starts, will be activated the open collector output (OC-0V on the connector J2 of the instrument terminal board), that through a relay will energize the solenoid valve mounted on the sample gas cylinder. This output, when SPAN will terminate, will be automatically deactivated. Note: The OXY version will activate the open collector output (OC-0V) during “ZERO” phase calibration.

WAIT FOR VALUE RETURN TO ZERO



5.3 CALIBRATION ERROR During Zero calibration procedure if the sensor is not placed in clean free air, and in case of Oxy model is not in presence of Nitrogen, this generates a Zero calibration failure and the display will shows:

CALIBRATION ERROR

PLEASE REMOVE TEST GAS

During Span calibration will appear the same message if the gas applied is not the correct one or gas is not applied within 60 seconds. A new message will be displayed as: WARNING: In case calibration error will be displayed a new calibration should start in order to correctly calibrate the sensor. The Oxygen Detector can be calibrate also in Warning-Alarm conditions (see par 5.1) but the previous condition will be deleted, therefore the relays will be in OFF condition along Modbus signals, and the current signal will be 2mA (or other setting). The display will show :

CAUTION: THIS OPERATION DELETE ALM WARN SIGNALS
