For part number 30390072, these parameters are preset by the manufacturer. Before purchasing, be sure to check the marking on the housing of your old unit against the specifications of the new one. Typical combinations for CM381N.4 may be: tv/tp = 5 s, ts = 10 s, tw = 5 s (e.g., art. 30390071); tv/tp = 30 s, ts = 5 s, tw = 30 s (e.g., art. 30390073). For part number 30390072, check the current values with the seller or from the marking on the housing. Mismatched parameters will lead to incorrect operation or safety lockouts.
