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