Page 4: １．Product Outline
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 OX-592. This instruction manual is just a guide book to operate indicator/alarm unit OX-592 of RM-590 series. Your kind reading of this manual is requested not only for first user but for already experienced staff. -
Page 7: Caution Items
２－３．Caution items CAUTION ・ Do not use walky-talky, mobile phone, etc. 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 emission. -

４．HOW TO USE ４－１．Before operation Be sure to keep caution items of use not only for first user but for already experienced staff. If not keep these caution items, the unit may be defective and correct gas detection may not be performed. ４－２．Mounting/dismounting procedures Indicator/alarm unit for RM-590 series shall be used after housing it in either exclusive single case or multi-unit case. - Page 13 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. If installed, inside the unit will be built up condensation and does not follow the drastic temperature change.

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. - Page 15 (Low pressure relay) －How to think alarm contacts against inductive load－ The spec for alarm contact of OX-592 is described by the conditions of resistive 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.
- Page 16 CAUTION ・The inductive load shall not be used in principle (Do not use fluorescent lamp). ・When use the inductive load, make the contact amplification outside, but the outside relay coil belong, use the relay driven by the low voltage (within AC100V) and it is protected by an appropriate surge killer.

５．OPERATION METHOD ５－１．Preparation for start-up ●Before putting power ON…………… Before putting power ON, keep following caution items. If not, danger for electric shock or damage to the unit will be happen. (1) Make grounding. (2) Check that wirings with outer units are made correctly. (3) Check that the supply voltage is within a rating. - Page 19 ５－３．Start-up method ５－３－１．Power on Cover Power switch 1) Before making power on, check that the unit is connected correctly. 2) The power switch can be seen when the front cover is opened. 3) Put the power switch upward to ON and downward to OFF. 4) Put the power switch on, and power light illuminates.
- Page 28 ６．KIND OF ALARM AND ITS FUNCTION ６－１．Kinds of alarm There are two kinds of alarm such as gas alarm and trouble alarm. ・Gas alarm ： When detection gas reaches preset alarm level or exceeds it, this starts an alarm. 《Latched mode → Self reset after reset operation.》 ＊...
- Page 29 ６－２－３．Gas alarm possibility except the case of gas detection It may respond to interference gas For interference gases, contact the nearest agent or RIKEN KEIKI. It may be caused by drifting due to the change of long time elapsed sensor Check the reading by daily check and make calibration through authorized service agent whenever necessary.
- Page 30 To maintain the safety operation of the unit, it is recommended to keep the maintenance contract with service agent for regular maintenance, adjustment and overhaul etc including the gas sensitivity adjustment. For the detail of maintenance contract, contact our nearest service agent or RIKEN KEIKI.
- Page 31 ７－３．Replacement of sensor and parts CAUTION For replacement of sensors and parts etc, contact our service agent or RIKEN KEIKI. ７－４．Treatment when operation is stopped or its installation place is moved. ７－４－１．Stop at normal operation Make the power switch off on the front panel.
- Page 32 ９－２．Counteraction at trouble alarm When any trouble was found on this unit and detector head, contact our nearest agent or RIKEN KEIKI. ９－３．Before it is thought to be trouble It may be originated from disconnection and short circuit between units.
- Page 33 ・Non-connection of sensor, contact failure of connector and disconnection of sensor cable. ・Check “whether sensor is connected” or “the sensor cable connector is connected to the sensor. If can not be recovered, contact our nearest agent or RIKEN KEIKI. (5) Fuse disconnection ＜Performance＞...
- Page 34 １０．DEFINITION OF TERMS External output signal External output is as follows. Gas Concentration signal output : current transfer model (4-20mA) Alarm contact output :① Gas alarm (AL1) ② Gas alarm (AL2) ③ Trouble alarm Calibration By using calibration (standard) gas etc, it seeks for instrument reading, display value or set value and true value.
