Level control relay CDSU | Dinel-Level and Flow Measurement

Level control relay CDSU are dual-channel units designed to evaluate the states of the conductive probes. They include power supply 5 V AC for supplying the probes. The DIP switches enable to select a basic mode (an independent function of two limit sensors) or the level control mode between the maximum and minimum level (pump control). The level control relay allows continuous sensitivity adjustment and time delay set up by trimmer.

Features

  • The function of pump control (Low-high level control) or independent 2-channel function
  • For connection of one or two probes
  • Continuous sensitivity adjustment and time delay set up
  • Optical state indication
  • Cases for wall mounting or for mounting on DIN rail 35mm

Function description

Basic mode – “LC” switch in OFF position

  • Activation of the probe connected to IN 1 input causes the closing of the output relay RE 1 terminal 14; 15 (CDSU–522) or 7; 6 (CDSU–522–W) is closed and shining LED indicator “OUT 1”.
  • Activation of the probe connected to IN 2 input causes the closing of the output relay RE 2 terminals 4; 3 (CDSU–522) or 10, 11 (CDSU–522–W) is closed and shining LED indicator “OUT 2”.

Pump-up function – “LC” switch in ON position

  • When the level drops below the probe connected to IN 1 (MIN) input, the output relay RE 1 terminal 14; 15 (CDSU–522) or 7; 6 (CDSU–522–W) are closed. The LED indicator “OUT 1” starts shining. This starts the active device (pump, valve, etc.) and the level goes up. When the level reaches the position of the probe connected to IN 2 (MAX) input, the output relay RE 1 terminal 14; 15 (CDSU–522) or 7; 6 (CDSU–522–W) are open. This stops the active device and the level goes down. LED indicator “OUT 1” darkens.

Pump-down function – “LC” switch in ON position

  • When the level drops below the probe connected to IN 2 (MAX) input, the output relay RE 1 terminal 14; 16 (CDSU–522) or 7; 8 (CDSU–522–W) is closed. LED indicator “OUT 1” darkens. This starts the active device (pump, valve, etc.) and the level goes down. When the level reaches the position of the probe connected to IN 1 (MIN) input, the output relay RE 1 terminal 14; 16 (CDSU–522) or 7; 8 (CDSU–522–W) is open. This stops the active device and the level goes up. The LED indicator “OUT 1” starts shining.
