DETAILED PARAMETER DESCRIPTION<br />
Now it is known that Thermal Class 15 allows cold start and<br />
Thermal Class 30 is the upper limit. Thus you must select a<br />
Thermal Class between these two Thermal Classes by<br />
considering the number of starts per hour and the time<br />
interval between motor On-Off procedures.<br />
With a smaller Class selected, the motor protection will<br />
increase but, less starts per hour are allowed and longer<br />
time intervals between motor On-Off procedures are<br />
required.<br />
On the other hand with a higher Class selected, the motor<br />
might be operated closer to the limit, thus more starts per<br />
hour are allowed and shorter time intervals between motor<br />
On-Off procedures can be used.<br />
If you are not sure which Thermal Class should be adopted<br />
between these two limits, adopt the lowest Thermal Class<br />
firstly, and only during practical tests at full load operation<br />
select the Class that is more suitable to your requirements,<br />
without exceeding the upper limit.<br />
NOTE!<br />
If several Thermal Classes can be applied, program one that<br />
is most suitable for your application, protecting your motor<br />
according to your duty requirements.<br />
NOTE!<br />
If the motor is equipped with a temperature sensor (PTC or<br />
Thermostat) which is used for thermal protection, the<br />
thermal class of the SSW-03 Plus can be disabled by setting<br />
