2. IMPORTANT INSTRUCTION FOR THE SAFETY 2−1.Danger items DANGER This is not a explosion proof unit. Do not use it at places where combustible/explosive gases or vapours may exist. It is very danger to operate under such environment. 2−2.Warning items WARNING ・ Buzzer unit, indicator/alarm unit Do not connect other buzzer unit and indicator/alarm unit than that of for RM-590 series. If connected, this multi-unit case or other connected unit may be broken. ・ Power source Before supplying the power, confirm that the power source is a designated voltage. ・ Maximum monitoring capacity The maximum monitoring capacity is 12 points due to the capacity of power unit. ・ Necessity of protective grounding Do not cut inside or outside wire for earth, nor disconnect the wire from earth terminal. ...

2−3.Cautional items CAUTION ・ Do not use walky-talky near this unit. When this unit receives the electric waves by walky-talky etc near from the cable, this will effect the reading. When use the walky-talky, operate it at the place where there is no influence of electric wave ejection. ・ When make power on again, make it after an interval of over 5 seconds. When make power on within 5 seconds, there may be no normal operation. ・ When operate it not to follow this manual, repair it by other rating parts or modify it on his own, the safety and quality of products can not be secured. Then, when an accident take place by it, we cannot assure our responsibility on them. Take enough consideration for instrumentation to keep safety even if disconnection of power and signal lines, defect of operation or trouble would be happen due to unexpected reason. This is an electrical applied instrument. Be care it may be effected by power noise, electrostatic and electromagnetic noise. When use under such conditions, make protective treatment for use. ...

4.HOW TO USE 4 − 1 . Before operation Be sure to keep cautional items of use not only for first user but for already experienced staff. If not keep these cautional items, the unit may be defective and correct gas detection may not be performed. 4 − 2 . Mounting/dismounting procedures When mounting/dismounting indicator/alarm unit and buzzer unit for RM-590 series, make following procedures. (1)Mounting method ・Open the front cover of indicator/alarm unit and buzzer unit. ・Confirm that the power switch is at OFF ・With the disengagement lever at down position, mount into the case. (Confirm that the edge connector is put in firmly) ...

4 − 3 . Installation place CAUTION Do not install at places where direct sun drought or where the temperature is drastically changed. Keep away the system from direct sun drought or where the temperature of the system is drastically changed. Do not install it where vibration or shocks may take place. The system consists of fine electronics parts. Install them where to be stable not to crush or fall down. Keep the system from the equipment which may generate the noise (Unit & cable). Keep the system from the equipment which may give a high frequency in the surroundings and install it. ・Do not put the system jointly each. ・Do not wire the cable in parallel nor take access. Do not install it where the detection gas is deposited around. Do not install and make gas detection at the place where the sample gas is deposited. Do not install at the place where it is danger for maintenance service such as high voltage cable, etc. This unit is required to make maintenance regularly. Then, do not install at the place where there is danger at maintenance time. Do not install it where it is unable to make maintenance. When required to stop the system at maintenance time, unable to maintain if not remove a part of system ...

4 − 4 . Caution in the system engineering CAUTION Unstable power and noise may cause error of performance and alarm. For the system to use this unit, it is required to make design based on this manual descriptions. (1)Stable power used While the system gets stable at power failure, the external output and alarm contact may be on and the care for it must be taken. In such case, use the standby battery or take an appropriate action in the receiver side. Supply the following power to this unit . Power voltage 100〜240VAC, 50/60 Hz Approx 50msec. Power failure (For power failure of 50msec, it re-starts) ...

(4)Alarm contact ・Alarm contacts shall be used only for external buzzer and alarm light, and do not use it for the controlling use (such as solenoid valve control etc). When control the external load, the bad influence may be given to the system according to the load characteristics. In such case, the following countermeasure shall be taken to stabilize the action and protect the contents. ・Relayed by the low voltage relay and operate by connecting CR circuit (Spark Killer: SK) (Diode etc for DC) suited for relay coil directly to relay. ・Add CR circuit to the load side of relay on the request. CAUTION (FOR USE OF NORMALLY-CLOSED CONTACT) Normally-closed contact (Break contact) at non-existing condition may change to open contact in a moment due to physical shock. Whenever alarm signals from gas detectors are used with normally-closed contact, please put delayed-circuit (for about one second) to receiver side of normally-closed contact to avoid such phenomenon. ...
Page 14
Reference:By the condition of load, CR circuit may be better to install in the contact side but it is required to put in by checking the action of load. SK : Surge absorption filter SK SK V V Alarm contact Power supply Power supply Relay (Low pressure relay) −How to think alarm contacts against inductive load− When use the inductive load for alarm contacts, the very high reverse electromotive voltage may be generated and the following trouble tends to be produced.) ・Contact part of relay is melted adhesively and the contacts can no work. ・High voltage is put inside of indicator/alarm unit and then, electrical parts may be damaged. ・As it is big noise, the trouble action may be taken by the reckless drive of CPU. ...

5. CONNECTIONS OF EACH UNIT 5−1.Connection of power cable The power requirement of this multi-unit case is 100V 〜 240VAC ±10%, 50/60Hz. Apply power source within this specified range. Before connecting power cable, FG terminals shall be grounded.. Grounding resistance shall be according to D-class grounding(Resistance: below 100Ω). After grounding and it becomes in safety condition, make wirings for power source and others. 5−2. Connections of detector heads. Terminal numbers ③,④,⑤ and ⑥ are the connection of detector head. 5−3.Connections of relay outputs RM-590 series provides relay outputs for 1st alarm, 2nd alarm and trouble alarm in each unit. Also, buzzer unit provides relay outputs for total 1st alarm, total 2nd alarm and total trouble alarm. Rating of relay contact is 0.5A at 100VAC,1.5A at 30VDC(Resistive load). When connecting the load above rating, use auxiliary relay circuit. Power source for auxiliary relay Power source for utility Multi-unit case Terminal plate Auxiliary relay RY Alarm contact Load When the inductive load is used for alarm contact, connect an appropriate spark killer to the load side. 5−4.Connection of 4-2mA output The RM-590 series provides 4-20mADC output from each unit. The load to be connected is up to 300Ω(Max.). Use a shielded cable equivalent to CVVS for connection. ...
