8.4 Thermal switches
All SEG pumps have two sets of thermal switches
incorporated in the stator windings.
Thermal switch, circuit 1 (T1-T3), breaks the circuit
at a winding temperature of approx. 150 °C.
Thermal switch, circuit 2 (T1-T2), breaks the circuit
at a winding temperature of approx. 170 °C (threephase pumps) or 160 °C (single-phase pumps).
The maximum operating current of the thermal
switches is 0.5 A at 500 VAC and cos φ 0.6.
The switches must be able to break a coil in the
supply circuit.
In the case of standard pumps, both thermal
switches can (when closing the circuit after cooling)
generate automatic restarting of the pump via the
controller.
Warning
The pump must not run dry.
An additional level switch must be
installed to ensure that the pump is
stopped in case the stop level switch is
not operating.
Stop the pump when the liquid level
reaches the upper edge of the clamp on
the pump.
Float switches used in explosive
environments must be approved for
this application. They must be
connected to the Grundfos LC, LCD 108
LC 107, LC 110 pump controller via the
intrinsically safe LC-Ex4 barrier to
ensure a safe circuit.
Note This thermal switch must be connected
for all pumps.
Warning
After thermal cutout, explosion-proof
pumps must be restarted manually.
The thermal switch (circuit 2) must be
connected for manual restarting of
these pumps.
Warning
The separate motor-protective circuit
breaker/control box must not be
installed in potentially explosive
environments.
