SAFETY INSTRUCTIONS• The operation of the device must be in accordance with and strictly limited to the applications, as mentioned further on and on data-sheet.• Installation, commissioning and maintenance must be carried out by qualified personnel.• Only connect the device to the voltage specified in the technical features and on the label.• Disconnect all power sources from the device during interventions or maintenance tasks.• Ensure compatibility of the liquid with the chemical resistance of the controller's materials at operating pressure and temperature.APPLICATIONS- Level detection for liquidsDESCRIPTIONThe lateral level controller CNL, consists of a float fixed to a shaft which end has a magnet on metal models or a magnetic float on PPHmodels. The float is moved by the liquid and the magnet acts on a Reed contact isolated from the liquid.Protection of the reed contact and respect of its breaking capacity can be ensured by an amplifier relay, type ES 2001(data-sheet 530-01).MOUNTINGThe CNL 200 and CNL 250 are screwed onto the tank wall: fitting BSP-M ¾''.- Prepare the female thread on tank wall to fix the controller- Use PTFE ribbon or equivalent insulation to seal the fitting- Screw the controller onto the tank- Once mounted, the controller must be oriented so that the connector is oriented downwards (vertical tilting of the float).The nut near the support is used to position it correctly.In this case, the insulation will be achieved by the insulator.CNL 320 is fixed on the tank, after drilling with proper bore- Drill at Ø 22 mm the tank wall (thickness of the wall must not exceed 8 mm)- Insert the controller in the desired position according to the direction of action (vertical tilting) and the direction of action (see ''contactsetting'')- After installing the seal and the plastic washer, re-tighten the nut until the seal is crushed enough for the controller to be stuck on the tank.In this case, the insulation will be carried out by the cylindric seal.The CNL 450 is screwed onto the tank wall: fitting NPT-M ½''- Prepare the female thread on tank wall to fix the controller- Use PTFE ribbon or equivalent insulation to seal the fitting- Screw the controller onto the tank, making sure by means of the mark of the correct float position (vertical tilting) and the direction of action(see ''contact setting'')In this case, the insulation will be carried out by the insulatorNIV14-02-2022 M-526.01-EN-AA526-01 /2Side level controllersCNL22, Rue de la Voie des Bans · Z.I. de la gare · 95100 ARGENTEUILTelFax+33 (0)1 30 25 83 20+33 (0)1 34 10 16 05WebE-mailwww.bamo.euexport@bamo.frINTERNATIONAL |
