Description

Level control in conductive liquids trough two level probes (minimum and mass), with protection for maximum level.
Filling control relay in tanks with alarm by minimum level.
Protection of electric pumps against lack of water in tanks.
Timing adjustment (100 – 550 secs.) and Sensitivity 〔9 – 43〕/100 KΩ

Applications

• Control of level in conductive liquids, through three probes (minimum, maximum and mass), with possibility of timing for the probe of minimum
• Tank fill control
• Protection against spillage in tanks
• Sensitivity and timing adjustment

Operation

MODE A – Power the relay (green LED lights up – A.1)

The “S1” contact will arm when the liquid level reaches the lowest level of the probe (terminal 6) (the red led – “F.A.” No water).

The “S1” contact disarms when the liquid level reaches the maximum level of the probe (terminal 5) – switches off the red led – “F.A.” No water).

MODE B – (Shunt 8-9) – Timing

When the liquid reaches the minimum level probe (terminal 6), the “t” timer (adjustable from the front panel – from 100 to 550 sec.), At the end of which the “S1” .
