Page 8: Electrical Connection
At sensors with the length of electrodes greater than 300 mm it is necessary to use an auxiliary ≥ probe (e.g. conductive probe) when installing from above on non-conductive containers for the maximum detection reliability. The auxiliary electrode is connected electrically with the housing of ≥ the sensor. The recommended length of the auxiliary electrode and the distance from the sensors ≥ are shown in the picture. ≥ Suitable types of auxiliary electrodes are for example: Dinel CNP–18F–30 probes with an M18 ≥ thread or a PDE–18 plate electrode (see Accessories). ≥ ≥ Auxiliary electrode PDE–18 > Electrical connection to the sensor housing >... - Page 9 In the event of strong ambient electromagnetic interference, paralleling of conductors with power distribution, or for distribution to distances over 30 m, we recommend using a shielded cable and grounding the shielding on the side of the power source. © Dinel, s.r.o.

Explosion proof CLS–23Xi and XiT is provided by conformity with standards EN 60079- 0:2013+A11:2014, EN 60079-0:2012. Explosion proof CLS–23Xi and XiT is verified FTZÚ – AO 210 Ostrava – Radvanice: FTZÚ 12 ATEX 0106X. A declaration of conformity was issued for this device in the wording of Act No. 90/2016 Coll., as amended. Supplied electrical equipment matches the requirements of valid European directives for safety and electromagnetic compatibility. Special conditions for safe use of variant CLS–23Xi (XiT) If the apparatus is used as device of Group II and with using of an approved power supply device, which output parameters comply with required input parameters, it is necessary to have an galvanic separation or in case of apparatus without galvanic separation (Zener barriers) it is necessary to provide equipotential equalizing between sensor and barrier earthing point. Design CLS–23Xi-11 (12, 20, 21) can be used in zone 0. Other design DLS–23Xi can be used in zone 0 only electrode part and head with electronics can be used only in zone 1.

Page 14: Functional Safety
13 . Functional safety The CLS-23 capacitive level sensors meet the safety integrity level requirements according to stan- dard EN 61508. The sensors are intended for level height detection applications of liquids with increased safety demands in modes: • Overfill protection • Dry run protection In both modes, the sensors meet the requirements for functional safety at level SIL 1. The sensor electronics have 1oo1 architecture (single-channel without diagnostics). It is recommended to perform a function test of the sensor's safety function 1 per year. -
