Flag Drop Type Fault Indicator ZK Type

FLAG DROP TYPE FAULT INDICATOR ZK TYPE STRUCTURE System: Flag Drop Type Fault Indicator Indication & Reset operation: The fault signal generated by the outer protective relay contacts excites the operating coil and drop the indication flag in the annunciator. The display window of the flag changes from the normal condition of black to the fault condition of orange. Pushing up the reset lever returns the indicator flag to the original position, and window returns to normal condition black, if the fault signal was monentary and operating coil is not excited any more. Indication pattern: However if the fault signal is continuous and still excites the operating coil, indicator flag in the display window change to stripe pattern in orange and black by operating the reset lever. After the fault signal is disappear the flag automatically return to the normai condition black. ●Operation → : Manual resetting Normal condition Fault condition Continuous fault condition (Black) (Orange) (Stripe pattern) → : Automatic resetting SPECIFICATIONS (RATINGS, PERFORMANCE) Specification Type Voltage operation type Current operation type Rated insulation voltage (Ui) 250V Voltage 24V, 48V, 100 / 110V, 125V, 200 / 220V AC / DC, 240V AC - Coil rating Current - 0.5A, 0.7A, 1.0A, 2.0A DC Continuous input range 24V, 48V AC / DC: 80 to 130% Others: 70 to 130% 90 to 100% (in case of continuous input) Operating value Rating X 70% max.
