Conductivity level switch, series 200 – 201
INSTRUCTION MANUAL - English
Thank you for purchasing 200/1 series level switch.
Before using the device, please read carrefully this manual.
1 – Description
200 and 201 series are level switches for conductive liquids, with integral conductivity between 0.3 and 10000
S, according
to the model. They cannot be used with oily materials, neither insulating, or inflammable liquids. For the level measurement,
we recommend the use of our 395, 600 and 700 series, probes.
2 - Techinal characteristics
• dimensions are in millimeters:
• 2 front led lamps • 1 N.O. contact switch 5 A/230V a.c. resistive load
• absorption: 5 VA
• sensitivity and time delay (only 201) adjustment
• no electrolysis (for a.c. models only)
• weight: 220 gr
• protection class: IP40
• operating temperature: –20 + 60°C
• operation:
Water supply
: the pump stops when water level exceeds MAX; and starts when water level drops below MIN.
Drainage
: in the drawing above, move the wire connected to terminal #2, to terminal #3,. The pump starts when water level
exceeds MAX, and stops when water level drops below MIN.
