CHECKER LAMP FOR UVTRON® UV SOURCE L9657-03 The L9657-03 UV source is a UV lamp designed to check the operation of UVTRON flame sensors which are widely used for fire alarm and combustion monitoring devices. Since the L9657-03 is very small and highly reliable in lighting up, it can be assembled with a UVTRON into existing devices to check UVTRON operation easily and accurately. Checking UVTRON operation helps improve the reliability of the devices that use UVTRON flame sensors.

If the leads are heated excessively, the glass bulb may crack and the performance characteristics may deteriorate. ●Vibration and shock The L9657-03 is designed to pass vibration and shock tests in compliance with IEC 60068-2-6 (sinusoidal vibration test: 1.5 mm peak to peak, 100 m/s2,10 Hz to 500 Hz) and IEC 60068-2-27 (shock test: 1000 m/s2, 11 ms). However, if subjected to strong mechanical shocks such as drop impacts, the glass bulb might crack or the internal electrode deform, causing poor electrical characteristics. So use extreme caution when handling. ●Polarity The L9657-03 has an anode and cathode, so be sure to connect them with the correct polarity. Mistakenly reversing the connection polarity may cause malfunction or breakdown. ●Use in the dark Avoid using the L9657-03 in the dark at an illuminance of 50 lx or less. If used in the dark, a delay of 0.5 seconds or more may occur between the ON signal and the start of operation. ●Use after long-term storage The amount of ions inside the bulb decreases after a long period of storage and this may cause the discharge starting voltage to increase and a delay in lighting up as in the case in the dark. So before using the L9657-03 after long-term storage, make sure that it lights up properly. ■WARRANTY The L9657-03 is covered by a warranty for a period of one year after delivery. The warranty is limited to replacement of the defective product. Even if within one year after delivery, the warranty will not cover any defect when the operating time has exceeded the guaranteed life. The warranty will also not cover any malfunction or trouble caused by improper use or natural disaster. * UVTRON is a registered trademark of Hamamatsu Photonics K. K.
