ѓ ENGLISH ѓ Thank you for choosing Delta’s DVP series PLC. Delta releases DVP02LC-SL load cell module of weight measurement function. DVP02LC-SL provides 24-bit resolution applicable for 4-wire or 6-wire load cells with various eigenvalues. Therefore, the response time can be adjusted in coordination with each other according to users’ needs. On this basis, the market requirements on weight measurement can easily be met. EN a DVP02LC-SL is an OPEN-TYPE device. It should be installed in a control cabinet free of airborne dust, humidity, electric shock and vibration.

To prevent non-maintenance staff from operating DVP02LC-SL, or to prevent an accident from damaging DVP02LC-SL, the control cabinet in which DVP02LC-SL is installed should be equipped with a safeguard. For example, the control cabinet in which DVP02LC-SL is installed can be unlocked with a special tool or key. EN a DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check all wiring again before DVP02LC-SL is powered up. After DVP02LC-SL is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground terminal on DVP02LC-SL is correctly grounded in order to prevent electromagnetic interference. FR a DVP02LC-SL est un module OUVERT.

Il doit ktre installй que dans une enceinte protectrice (boitier, armoire, etc.) saine, dйpourvue de poussiиre, d’humiditй, de vibrations et hors d’atteinte des chocs йlectriques. La protection doit йviter que les personnes non habilitйes а la maintenance puissent accйder а l’appareil (par exemple, une clй ou un outil doivent ktre nйcessaire pour ouvrir a protection). FR a Ne pas appliquer la tension secteur sur les bornes d’entrйes/Sorties, ou l’appareil DVP02LC-SL pourra ktre endommagй. Merci de vйrifier encore une fois le cвblage avant la mise sous tension du DVP02LC-SL. Lors de la dйconnection de l’appareil, ne pas toucher les connecteurs dans la minute suivante.

Vйrifier que la terre est bien reliйe au connecteur de terre afin d’йviter toute interfйrence йlectromagnйtique. ѓ Product Profile & Dimensions 3 mm DVP02LC ERR OR L.V POW ER R UN C H1 SEN+ SIG- SIG+ EXC+ EXC- M OTION M AX ZER O N ET SEN- SHD 90 mm EXC+ EXC- 1.
