An hour (60 minutes) is divided by the set value to set the time to wait between
2 consecutive starts. For example, if PSS is set to '10' in this program, the
minimum time between starts will be 6 minutes, so a maximum of 10 starts per
hour are possible. The number of switches limit program should be adjusted
according to the power of the electric motor. It can be adjusted between 0 and
80 according to the engine power.
