DEIF RMV-112D Logic control module

If the 380/440V version is being commissioned, a step-up transformer is needed to allow the calibration of the settings to be checked. If no transformer is available, the alternative test method below should be used. Check that the led trip indicator is reset and slowly increase the ac voltage until the led on the front plate is fully illuminated. This is the pick-up value and should be recorded. The allowable errors on the voltage settings are ±2% on the lowest setting and ±4% on all other settings. (No allowance has been made for instrument errors). Alternative test method for 380/440V version of MVTD 12

This method should be used only 

when no step-up transformer is available. See Figure 3 for test circuit. First, accurately measure the resistance of the dropper resistor assembly (REXT2). With the relay on the lowest setting and the dropper resistor (REXT2) removed from the circuit, measure the pick-up voltage directly at the relay terminals (27 and 28) and the ac current into the relay at pick-up.The pick-up value should be within ±2% of the setting value. (No allowance has been made for instrument errors).
