By using this phase control, it is possible to control disturbances caused by two-phase, phase disconnection, phase asymmetry, phase shift and voltage increase or decrease in all industrial, commercial and residential centers.\r\n\r\n\r\n\r\n## Features of M series phase control of Shiva Amwaj\r\n##\r\n## Use of microprocessor system for accurate control of the power grid\r\n## Protection against:\r\n## Voltage increase and decrease\r\n## Non-sequence (displacement) and asymmetry of phases\r\n## Interruption of any of the phases\r\n## Biphasic\r\n##\r\n##\r\n## 4 markers for announcement\r\n## always on:\r\n## REL: Connect the relay\r\n## U : Voltage reduction\r\n## U^ : Asymmetry of phases\r\n## wink:\r\n## D: Timing to connect the relay\r\n## P : Null displacement\r\n## F: Phase interruption\r\n## SEQ: moving phases\r\n##\r\n##\r\n## 4 adjustment screws:\r\n## Connection time delay\r\n## Voltage increase\r\n## Voltage reduction\r\n## Asymmetry of phases\r\n\r\n\r\n**[Click here to view Delta products](https://www.automation24.ir/)**\r\n\r\n\r\n\r\nTechnical specifications of Shiva Amwaj phase control\r\nSupply voltage: phase R + zero - 180 to 250 volts AC (from 50 to 60 Hz)\r\nInput: three phases - 300 to 500 volts AC (from 50 to 60 Hz)\r\nTime delay:\r\nConnected: 2 to 240 seconds\r\nInterruption: 3 seconds\r\nInterruption to reduce the voltage at the moment of starting: 10 seconds\r\ncut off for:\r\nVoltage increase: 400 to 480 volts\r\nVoltage reduction: 300 to 380 volts\r\nAsymmetry: 5-25%\r\nEfficiency in:\r\nTemperature: between -20 and +65 degrees Celsius\r\nHumidity: 70%\r\nOutput: 10 amp relay\r\n \r\n \r\n phase control:\r\n\r\nThis device is designed to protect three-phase motors against excessive reduction or increase of network voltage, phase disconnection or phase shift, and in many cases, the cause of motor burning is incomplete connection of contactor contacts. As a result, the phase control is installed after the contactor.\r\n\r\nPhase control function:\r\n\r\nAfter three phases and zero are connected to terminals L1, L2, L3 and mp, if the voltages are suitable and the phase sequence is correct, the u indicator will light up. If the sequence of phases is not correct (the PH indicator turns on), this problem can be solved by changing the place of the two phases, and after the delay time passes, when the RLY light turns on, the contact 15 of the relay is disconnected from 16 and connected to 18. If there is any problem in the network, the corresponding indicator lights up. Internal relay RLY turns off.\r\n\r\n\r\n\r\nRelay settings:\r\n\r\nThere are two adjustment screws on most of the phase controls, which are as follows:\r\n\r\nReaction time: With this adjustment screw, the cut-off delay time can be set, which is used to cover the start time and prevent the relay from operating in unfavorable situations.\r\n\r\nPhase loss sensitivity: with this adjustment screw can be asymmetric
