Connection diagram: Motor Phase Protection Relays Motor Phase Protection Relays protects motor against lack of the phase, phase error, voltage unbalance and overheating at three phase systems. Protect Function: 1) Phase error: Phase error: If one or two of phases are absent before giving energy to the motor; relay blocks the energy flow to motor by deactivate the output. 2) Temperature Protection: If the winding temperature of the motor is exceed the temperature limit value of PTC regardless phase voltages motor deactivates. 3) Voltage Unbalance: If Phase-Neutral voltage unbalance exceeds...

• • • • • Pic-3 FSMK Phase Sequence and Motor Protection Relay Connection Diagram: FSMK Phase Sequence and Motor Protection Relay Manufactured in accordance with CE. Protection functions fulfilled by the phase sequence and motor protection relay, which is intended to prevent failures in electrical motors widely used at industrial facilities, are shown below. 1. Phase Cut-off: Motor is disabled if it remains on 1 or 2 phases for any reason. 2. Voltage Imbalance: Motor is disabled if neutral-phase voltage imbalance exceeds the level of 20% (optionally 40%). 3. Phase Sequence: When phase...

Liquid Level Relay: The pomp motors where installed at Industrial tanks, water tanks, artesian well are controlled by Liquid Level Relays. Each relay has 3 electrodes which provide to fill up and discharge of tanks and well. Operation and working procedures Normally it is used 3 electrodes as bottom, lower and upper. When tank or frame is made by metal, it is not necessary for bottom electrode. In this case the relay output for bottom is directly connected to metal body of tank. A) Discharging of Tank. The output of relay number 2 and 3 are connected to motor connection terminal as...

FS72 Counter Federal counter, which is manufactured in accordance with CE, counts depending on impulse input and multiplier factor. As the counting is performed under control of microprocessor, rate of errors is very low. FS 72 may keep program parameters and latest value for 10 years, even if there is an electricity failure. Pulse can be entered in FS 72 counter via encoder, proximity switch and contact. Input frequency is 130 Hz maximum. Technical Specifications:: Operating voltage : Sensor supply output : 220 V AC 50 Hz 1NA,1NK 250 V / 5 A AC On led while relay is drawn In front of...
