3. Temperature Limiters
3.1 Temperature Limiters with
Mechanical Interlock (restart
lockout)
Max. Temperature Limitation (...-205)
When the temperature
exceeds
the value
set on the scale, the microswitch switches
over and remains in this position. The
catch can be released by pressing in the
unlocking button (marked on the scale
side of the switching device by a red dot).
The limiter cannot be unlocked until the
temperature has
decreased
by approx.
8-10 K.
Min. Temperature Limitation (...-206)
Na When temperature
falls below
the
value set on the scale, the microswitch
switches over and remains in this
position. The catch can be released by
pressing the unlocking button (marked on
the scale side of the switching device by
a red dot). The limiter cannot be unlocked
until the temperature has
increased
by
approx. 8-10 K.
3.2 Interlock in the Control
Cabinet
A thermostat can act as a temperature
limiter if interlock function is provided by
electrical circuitry. Below are two
examples for interlock circuitry.
NOTE:
In any case, valid standards (e.g., DIN EN
50156 / VDE 0116-1 and valid local
standards) must be observed for design of
electrical interlocking circuitry.
