A Ekip Touch protection trip unit | 12 - G Touch protectionsOP ProtectionP26tt26POPPathMain page - Menu - AdvancedFunctionOP protection trips when the active supplied rises above the set threshold.If the active power rises above the activation threshold, the protection trips within a fixed time set by the user.ParametersIt is possible to modify various parameters:Parameter DescriptionEnable To activate/deactivate the protection.Threshold P26It defines the active power value above which the protection is activated (withreference to the figure above, the threshold is the part of the curve parallel tothe y-axis).It is represented both as an absolute value (kW) and a relative value (Sn,referring to the rated voltage set on the trip unit).Time t26The delay time between the exceeding of the P26 threshold and the sending ofthe opening command (with reference to the figure above, the threshold is thepart of the curve parallel to the x-axis).OP protection has StartUp enable, see page 71.Via Ekip Connect it is also possible to access the blocking functions, see page 72.UP ProtectionP23tt23PUPPathMain page - Menu - AdvancedFunctionUP protection trips when the power supplied drops below the set threshold.If the active power drops below the activation threshold, the protection trips within a fixed time set by theuser.NOTE:• The protection is not active for voltages <30V and if the circuit-breaker is open.• The protection is active also for negative (reverse) active power, but is independent from the RPprotection (protection against reverse active power).ParametersIt is possible to modify various parameters:Parameter DescriptionEnable To activate/deactivate the protection.Threshold P23It defines the active power value below which the protection is activated (withreference to the figure above, the threshold is the part of the curve parallel tothe y-axis).It is represented both as an absolute value (kW) and a relative value (Sn,nominal value defined on the trip unit).Time t23The delay time between the exceeding of the P23 threshold and the sending ofthe opening command (with reference to the figure above, the threshold is thepart of the curve parallel to the x-axis).UP protection has Trip Enable and Startup Enable , see page 71.Via Ekip Connect it is also possible to access the blocking functions, see page 72.
