１．PRODUCT OUTLINE
１－１．In the beginning
First of all, we wish to express our heartfelt thanks for your purchase of our indicator/alarm unit EC-592.
This instruction manual is just a guide book to operate indicator/alarm unit EC-592 of RM-590 series.
Your kind reading of this manual is requested not only for first user but for already experienced staff.
１－２．Application for use
○This is a exclusive indicator/alarm unit to be used in combination with our electrochemical sensor type toxic
gas detector head.
○Toxic gas leaked into ambient air is detected with toxic gas detector head which is connected with this
indicator/alarm unit. Detection results (Gas concentrations) are displayed with 4-digit LED indicator.
○This unit outputs 4-20mADC as gas concentration signal.
○This unit provides 2 relay contacts for outer gas alarm.
１－３．Identification of each cautional marks
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury. This signal word is to be limited to the most extreme situation.
Indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert against unsafe practices.
This means “ADVICE”at operation.

２．IMPORTANT INSTRUCTION FOR THE SAFETY
２－１．Danger items
２－２．Warning items
This is not a explosion proof unit. Do not use it at hazardous area.
DANGER
・Detector head
Do not connect other detector head than designated toxic gas detector head.
If connected, you can not detect gas. Furthermore, this unit or other connected unit may be broken.
・Power source
Before supplying the power, confirm that the power source is a designated voltage.
・Necessity of protective grounding
Do not cut inside or outside wire for earth, nor disconnect the wire from earth terminal..
In any case, the unit becomes dangerous conditions.
・Defect of protective function
Do not operate the unit if protective functions such as protective grounding or fuse are seems to be defective.
Also, before operating the unit confirm that there is no defect for protective functions.
・Fuse
Use the designated rating (current, voltage, type) fuse to prevent fire.
Replacement of fuse shall be done after put off the initial power source and put off the power switch of this unit.
Do not use other fuse than designated one, nor make short circuit for fuse holder.
・External connections
After making protective grounding firmly, connect to external control circuit or detection objective.
・Counteraction at gas alarm
When detect high concentration gas than preset alarm level, it is very dangerous.
It is required to take an appropriate measures by customer’s decision.
・Mounting/dismounting
Locking mechanism may be broken if the unit is mounted into the case with disengagement lever up
position. Make correct procedure for mounting/dismounting..
WARNING

２－３．Cautional items
・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.
