NOTES!
 When SSW-07 is without the electronic supply voltage (A1 and
A2), the thermal image is saved internally. When the supply (A1
and A2) is re-established, the thermal image value returns to the
value prior to the electronic supply loss.
 The RESET of the electronic overload protection can be set
to manual function (man). In this case the RESET must be
made via digital input 2 (DI2) or through the RESET key. If the
RESET setting is set to automatic (auto), the fault condition will
automatically be reset after the equipment cooling time;
 Upon disabling the electronic overload protection, the thermal
image is reset at zero.
