REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 1-1 1 INTRODUCTION 1.1 SYSTEM DESCRIPTION A range of Remote Intelligent Sensors (RIS) are available.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 1-2 Instruction 2772-0803 On the main board are mounted several potenti- ometers and ‘dip’ switches. These should not nor- mally be touched, particularly dip switch 1 . However, a potentiometer (POT) is provided for user adjustment of the pump flow rate.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 1-3 1.3.8 SAMPLE INLET. The sample is brought into the RIS through the short length of black FEP tube and into the optic block.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 1-4 Instruction 2772-0803 NOTES.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 2-1 2 INSTALLATION AND SYSTEM CHECK The RIS may be installed inside or out. It should be mounted and connected according to the instructions provided below, and in an environment that is within the specified limits detailed in the Product Specification.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 2-2 Instruction 2772-0803 When input connections have been made, and 12 volts DC is available at J1 terminals #1 & 2, leave the system connected overnight with system switch, SW1, off during the recharge .
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 2-3 2.5.2.3 ‘Worst Case’ Current. Low Flow RIS. A practical ‘worst case’ current of 500 mA may be considered reasonable under most situations. Where long-term power disruptions (more than 2 hours) are likely, it may be prudent to assume 550 - 700 mA ‘worst case’.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 2-4 Instruction 2772-0803 2.6.3 REACTIVE GASES. Many gases are extremely liable to attenuation and no extension of input tube should be attempted . These gases include ISOCYANATES, HYDRAZINES and ACID GASES such as HF and HCI.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 2-5 If the ‘O’ ring is left on the purge spigot the new cassette will not seat fully and faulty tape handling will occur. Push the new cassette firmly into position. When doing so make sure that the tape enters the open gate and does not catch on the side and break.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 2-6 Instruction 2772-0803 Alarm Level 1 is displayed first and is identified by the number 1 which is shown in addition to the numerical set point value. Similarly, the Alarm level 2 set point which follows, is identified by a 2.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 2-7 2.9 OPTION PCB INSTALLATION Under the cover on the main board are three slots for mounting option boards. An option board can be inserted in any available slot. The two option cards available are the Serial Printer Interface PCB, and the Alarm Relay PCB (See Section 5.

REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 3-1 Effective purging requires the enclosure to be properly sealed. Ensure that the cable glands and the door are air tight. Unused cable glands can be tightened onto a short piece of cable.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 3-2 Instruction 2772-0803 This method eliminates the ‘zero drift’ that could otherwise occur with slight variation in the reflective value of the tape. It also ensures that system accuracy is not compromised when reusing the same tape spot.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 3-3 Flashing This symbol shows that sampling vacuum has dropped. The cause could be a pump failure or an air leak. Optics Icon warns that the light level is not acceptable. In addition, the affected channel is shown by a 1 or 2, or both.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 3-4 Instruction 2772-0803 3.8.3 FAULT RELAY. With the basic system the single (combined) gas alarm/fault relay is operated to provide external warning of any of the monitored ‘fault’ conditions. In a fault condition, the relay output ‘toggles’ open and closed at 1 Hz.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 3-5 IMPORTANT: Please note that this method is not suitable for, and is not intended to be used for, checking or verifying the system’s calibration, but only for alarm simulation and checks.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 3-6 Instruction 2772-0803 In addition to that supplied by GMD, printers meeting the specification detailed below may be used. Those intending to use an alternative printer should check the specification carefully.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 3-7 3.14.3.4 Printed Date Format. A choice of month/ day or day/month format is available: For the US month/day/year format, set SW2 switches 1 and 2 ‘ON’. For the European day/month/year format, set SW2 switches 1 and 2 ‘OFF’.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 3-8 Instruction 2772-0803 The plug can then be cut off and the wire ends prepared for termination in a plug that will mate with that fitted on the RIS. The plug should be connected in accordance with the following table.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 4-1 Allow the Test data to cycle to the light level value (track 1), HOLD the display and check that the reading is near 220. RELEASE the track 1 display and then HOLD to check track 2.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 4-2 Instruction 2772-0803 With the tape in place, adjust the track 1 potentiometer until the reading is 220. Clockwise rotation of potentiometers increases the level. When track 1 has been adjusted, press the HOLD/RELEASE button to allow track 2 to be displayed.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 4-3 4.8 MEASURING PUMP CURRENT To establish the pump run current, first check the system current in the TEST Mode. Then the total current is measured as detailed below and the TEST Mode current deducted from total current to give pump current.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 4-4 Instruction 2772-0803 Repeat several times, also with the gate open. If a can of pressurized air is available, carefully position tube at the tape side of the gate and blow again several times. Suitable cans of air are usually available from photographic suppliers.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Instruction 2772-0803 Page 4-5 NOTE: If it is not possible to achieve a satisfactory average tape step length, please refer to additional information in Section 4.21.2. Figure 4-7. Summary of Gate & Step Values 4.
REMOTE INTELLIGENT SENSOR - AREA MONITOR Page 4-6 Instruction 2772-0803 4.11.2 REMOVAL OF THE MECHANICAL CHASSIS. Remove the cassette, undo the two ribbon cable connectors and the two hose couplings in the tubes that connect the chassis to the body of the instrument.
