Connections
Automatic Water Supply and Drainage Control
1. Water supply
• Connect electromagnetic switch coil terminal A to Tb.
• The pump stops when the water level reaches E1 and starts when
Operation
The conductive type level controller consists of a plug-in controller
connected to a set of stainless steel probes. These are cut to length
and inserted vertically into the liquid. A low voltage is applied
between these probes and the earth probe (or tank, if it is electrically
conductive). The water provides a current between the earth probe
and the high-level probe. The output relay in the controller is ener-
gized when the water level reaches the high-level probe and de-ener-
gized when the water level falls below it.

• The pump starts when the water level reaches E1 and stops when
Note: 1. The diagram shows the connections for water supply. When
For two-point control a low-level probe is used as well. In this case
the relay does not de-energize until the water level falls below the
low-level probe. Using the low-level probe allows a wide differential
between switching a pump on and off, and can avoid excessive pump
operation during tank emptying or filling. If this differential is not
required, the low-level probe need not be connected.
