Start proof display three-phase soft starter operating current and zero sequence leakage current and power supply voltage of the motor and the motor line at work, and shows the cumulative motor running time, and is not blackouts, easy to understand the equipment running cumulative time, easy to carry out regular maintenance and repair. 6. Display of the operating parameters are Chinese color HMI touch screen display, very intuitive and easy to set parameters. 7. according to user requirements with profibus dp communication interface, and remote monitoring on the level of computer networking communications and remote control. Description of the parameter setting function touch screen panel is displayed: Run cumulative (RUNtime): 0-9999 hours (S); but the count is automatically previous cumulative run time, and the impact of power outage, after the expiration of 9999 hours back to zero start. Starting time: seconds; 0.1 and 99.9 seconds (S) parking time: seconds; 0.1 and 99.9 seconds (S) overload current: Unit for A; generally set at about 1.2 times the rated current of the motor nameplate. Does not work in the motor during starting. When the soft starter into the run time, if the motor current reaches or exceeds this value, the controller will perform inverse time overload time, when it reaches the overload time set time, the soft starter will stop working and generate an alarm signal overload tips. Overload time: 0.1-199.9 seconds (S); when the motor current exceeds the set value overload current exceeds the set time, overload alarm is generated. This time with inverse time protection features, namely the greater the overload current actual current exceeds a set value, the protection of the shorter time. Starting voltage: Value range: 10-90%; start voltage when starting, corresponding to 10% -90% power supply voltage, the user can be set adjusted according to the actual situation of the field device. Zero sequence current: the value of the unit A, the actual detection of zero sequence current transformer signal range is 0.01-9.99A. The display is the actual value of the zero-sequence current value by the soft starter are connected to the output of the zero-sequence current transformer detected, can not be modified. Different types of users, such as the replacement of transformers shall control potentiometer P4 motherboard adjust proofreading. Starting limiting: the unit is A: The current value is the maximum current value during motor starting. In the start-up process, when the starting current of the motor reaches this value, the starter will start to increase the current limit, then the start time is set to become the biggest value of the guard time, if the load is too heavy due to causes in the starting set Start time is not yet complete, it will stop and have a "starting time" alarm, such as equipment normally available through the current value or increase the starting time limit increases to solve, we must pay attention! The value must not exceed the maximum set twice "mutual current" set value! When starting mode is selected as "buck", the parameter value is invalid. Leakage Protection: The value of units of A, the range of 0.01-9.99A. The set value is the value of the leakage current protection. When the value is set to 0.00A, this function is disabled. The current value is determined by the output of the soft starter zero-sequence current transformer connected to the detected value, when the output cable or high-voltage electrical insulation on bad ground leakage current, if the zero-sequence current transformer to the detected When the leakage current is greater than the set value, and the duration of time greater than the set value of a leak, the soft starter cabinet will stop immediately and produce (leakage blocking protection alarm) fault alarm display. When first-time users, the value can be set to the maximum, the maximum leakage current when first starting equipment observe display (usually in the starting process) and run-time general average wait after shutdown Set this parameter is greater than 20-30% of the actual leakage current can be. Leakage delay: The value of units of seconds, the range of 0.1 to 5.0 seconds. The set value is the value of the leakage current protection operation delay. When the value is set to 0.0 seconds, is the instantaneous action protection. Due to a variety of complex situations transmission cables and high-voltage electric motor when the motor is just starting the leakage current is large, but also small leakage current run, this time by setting the appropriate time delay protection, which can effectively prevent leakage protection malfunction that is, if the leakage current exceeds the user should pay attention on one! The delay function leakage into the normal operation of the motor that fails, that once the leakage current exceeds the current value of leakage protection, the soft starter will stop immediately and produce (leakage blocking protection alarm) fault alarm display. Overpressure protection: Unit for KV: This parameter is to protect the device does not work in the power supply voltage is too high the environment, and can be set at + 20% to + 25% of rated voltage, when the supply voltage exceeds the set value, The soft starter will generate (ultra-high voltage power supply alarm) fault alarm display. Undervoltage protection: Unit for KV: This parameter is to protect the device does not work due to the low power supply voltage environment, and can be set at about 35% of the rated voltage, when the supply voltage drops below the set value, the soft start will produce (supply voltage undervoltage alarm) fault alarm display. Current transformers: Unit for A: The parameters can be modified within the manufacturer of the machine transformer data set required engineers to change your password. Start Mode: Normal mode: In this mode, the motor starting from the set of "starting voltage" in a low-voltage, beginning with the start time set gradually linearly increase the output voltage until the start time ends. Low-frequency mode: especially suitable for large mechanical friction and inertia of large mechanical equipment, then start with a frequency 25HZ started when the cabinet, the motor can produce high starting torque in a small startup current, can greatly extend the life of the equipment. (This function is only used for special requirements of users overloaded start) when needed ordering. Low-voltage: This setting is low-voltage setpoint runtime. Engineer Change Password: The password value is 168. When you press the reset button, the password will be cleared. Chinese fault alarm screen display shows the contents: Motor overload alarm: the motor current has exceeded the overcurrent load current value set, and the time delay value exceeds the over load time set. The alarm will automatically reset command to undo the operation! Input power phase alarm: Three-phase input power supply controller has a similar power. Should check the input power. Abnormal motor current alarm: the motor phase or three-phase windings are three-phase current serious imbalance. Start timeout alarm: This is an alarm during starting to appear, and when you first use because "start limiting" value is too small, or "start time" value too, by increasing the "start limiting" value or "start time" value to resolve. This alarm is generated after normal use is caused by mechanical overload, should identify the reasons for re-start. Bypass switch fault alarm: After starting the device is completed, when put into operation, the bypass contactor is not closed, the number of contacts with a number I9 L1 contact is not turned down after waiting for five seconds after the alarm. Motor zero sequence leakage alarm: When the analog input port LH1, LH2 leakage signal value of the connected zero sequence current transformer leakage protection is greater than the value of a setting, the soft starter will stop and generate the alarm. When a user first installation, should leakage current range adjustment and proofreading. Ultra-high voltage power supply alarm: when the supply voltage exceeds the "overpressure protection," a set value, indicating that the power supply voltage has exceeded the protection value. Mains undervoltage alarm: when the supply voltage drops below the set value "undervoltage protection" A, indicating the supply voltage has been below the protection value. Power Devices damage alarm: When the soft starter main circuit A, B, C three-phase thyristor module breakdown when any group is damaged, the alarm will be generated. Attention! When the soft starter 380V low pressure debug panel should "Device protection" A ban is set, otherwise this will generate false alarms. After more than an alarm leads to stop running after troubleshooting by identifying the reasons (reset) button on the control panel is able to clear the alarm.
