 TDM  Relay  for control of temperature and sealing in pumps , mixer

                                                 User's Manual

1. Working principle:

 - At power up the relays are activated and the LED "POWER" is light up,

alarm contacts are opened and contact for pump control is closed.

- When the thermostat in the pump opens due to high temperature in the

motor winding the LED ''Temp./TCS'' is light up, the alarm contact is closed and the control circuit contact is opened. When the temperature drops, the systems automatically resets.

- When the resistance between the sealing electrode in the pump and earth

decreases to approx. 27 kOhm (due to water ingress) the LED "Sealing/DI" is light up and the alarm contact is closed. The alarm automatically resets when the resistance again increased.
