The low and high limit parameters for supply voltage must be set within the specified voltage range of the control unit.
This function block monitors voltages, temperatures and the program cycle time of the control unit. All the voltages and temperatures have high and low limits, both signaled with a boolean output when exceeded. Each measurement limit has it's own parameter. Only the high limit of the program cycle time can be set and monitored.
