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 normal 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.

PILOT LAMP & INDICATOR TECHNICAL DATA Operating condition of current type For the current operation type, it is sometimes used by connecting in series with a relay equipped with a self-cutoff contact in the manner shown in Figure 1; in that case, current I shows the waveform shown in Figure 2 depending on the coil inductance of those serial relays. Voltage V waveform P Relay Ry Current waveform Calculated circuit current value Voltage V Calculated circuit current value Current ZK 30 200% or more current of rating Rectangle N 1 10 msec or more Figure 2. Voltage and current waveform When high-speed operation is required (operation at 200% or more of rated current and minimum input pulse of 10 msec or less), please select a coil rating that can secure a rectangle 1 within the actual circuit current waveform. High-speed operation is confirmed in the condition with the resistance value of the serial relay (Fig. 1 Ry) in the following table.
