Page 3: Introduction
Introduction In the event of oil leaking out due to any accidental cause at an industrial lot where a large volume of oil is handled, the most important matter is to detect its occurrence without delay and to dispose of it quickly and adequately. "Apolarm-C"... -

Page 5: Functional Theory Of "Apolarm-C
Functional theory of “Apolarm-C” ■Detector (Fig.4-1) (a) Way of detection When all of the detecting electrodes come in contact with oil at an oil depth from 3 to 5 mm, this device functions to detect the presence of oil there. When any of the electrodes, even only one electrode, is in contact with water, no detection signal is sent out from the device. - Page 6 ■ Principle and structure (Fig.4-2) Model CSR-3005E is an intrinsic safety type explosion-proof transducer. Floater has three electrodes, and high frequency current provided from its detector circuit checks the electrostatic capacity at the electrode section. When oil flows out onto water surface, the electrodes have to contact water through the oil layer, which causes their electrostatic capacity to vary largely.

Electric energy may accumulate in this cable and such energy may work to impair the intrinsic safety of the device. For this reason, the maximum wiring cable length is restricted under the explosion-proofing principles.

Page 12: Dry Pit Attachment
5-3. Dry pit attachment In case there is no water ordinarily or there is a fear of water being emptied, dry pit attachment is used. When the water level drops, the electrode points come in contact with the contact plate of the attachment and cease to further go down. Therefore, the electrodes are earthed as are when floating on water. -

Page 15: Installation Of Apolarm-C
Installation of Apolarm-C 7-1. Determination of place for installation The thickness of oil layer produced by leaked oil gets the thinner the wider the dispersed area of the oil. Therefore, it is important how to gather the leaked oil in a limited area. Gathering of oil in a small area makes easier the work of oil recovering, which leads to thwarting the mishap from expanding further. - Page 16 b) An installation example in oil separation pit ■Oil separation pit Junction box APOLARM-C Oil separation pit ① As generally the oil separation pit is filled with water. Therefore, it is unnecessary to set dry pit attachment there. When the oil pit is emptied, warning signal is send forth. ②...

Page 18: Cautions For Installation Work
7-3. Cautions for installation work (1) Relation between oil layer thickness detectable and out flowing amount of oil The amount the leaked-out oil is required to reach after oil begins to leak out for the detector to start giving out oil detection signal is indicated by the following formula: Amount of leaked-out oil = (oil layer thickness detectable by detector) ×... - Page 19 A high frequency (around 1 MHz) is used inside this detector, which, therefore, may issue false signal if a transceiver or other high frequency source is nearby. Though this new Apolarm (CSR-3005E) has enhanced its immunity against external interference, do not use, as much as possible, such a transceiver, etc. near the Apolarm.

8-2. Wiring of intrinsically safe circuit (Guide for the Installation of Explosion-proofed Electrical Equipment 9.6) (1) When Aploarm-C cable needs to be installed near other cables, Apolarm cable must be wired independently by using metal pipe or metal duct in order to prevent power cross, static induction and electromagnetic induction. -

Panel wiring at non-hazardous area (Guide for the Installation of Explosion-proofed Electrical Equipment 9.6.6.7) In the event of wiring intrinsically safe circuit inside the instrument panel in non-hazardous area, be sure to follow the instructions below. In general, the panel must have a relay box for external wiring of this relay box should be installed inside the panel. -
