The display window changes from black (N1.5) indicating the normal status to orange (2.5YR6/13) indicating the failure status. ●When the reset button is pressed, the display panel will be returned to blank. If the failure is instantaneous and no input is provided, the display window will return to the black display in the normal status. If the failure persists, however, the coil receives input and a pattern of stripes of orange and black is displayed indicating that the failure persists. Once the failure is rectified, the display will automatically return to the black display in the normal status. ●Max. 4 contacts are available. Contacts interlocked with the display panel may be taken for a maximum of 2 circuits. Those interlocked with the coil may be taken for a maximum of 3 circuits. One-shot pulse contacts interlocked with the display panel may be taken for a maximum of 2 circuits. Each circuit is provided with contacts a and b. ●The one-shot pulse contacts output pulses (50 to 70 ms) at the initial operation only. ●Standard specication Ｒｙ Coil voltage ＋9 7 5 3 1 Black Orange ａ2 ａ2 ａ1 ａ3 Stripe pattern 30 ´ Contact which interlocked with flag (a contact) a1 Contact which interlocked with coil (a contact) a2・a2 One-shot pulse a3 ´ －10 8 6 4 2 Manual reset operation 1: All the coils for voltage type are added a counter induced-voltage absorption device. ●Power monitor specication (Normally excited type) Coil voltage Black Orange / Red Contact which interlocked with flag ～ Remark ～ (a contact) a Contact which interlocked with coil The coil is normally in excited status (black).
