Rise time: 1 ns Pulse width: 1 μs, 50 ns
Polarity: ± Cycle: 10 ms
(Note 1): Accurate measurement may not be possible if excessive noise gets added to the input line.
If an error occurs, the following displays will be given.
|Display||Meaning||Output status||Restoration procedure||Status after restoration|
|ERR00||CPU error||OFF||Turn the power off and then on again.||The display at start-up before the CPU malfunction occurred.|
|EEPROM life ended.
Replace the main unit.
|(Note 2):||Includes the possibility that the EEPROM's life has expired.|
Please make sure to check wiring in dimensions page in each product page.
|Note:||Please connect a breaker (3 to 15A) to the voltage input part for safety reasons and to protect the device. Grounding the secondary side of VT (Voltage transformer) and CT (Current transformer) is not necessary with low-voltage circuit.|
How to connect for measuring by combination with CT (secondary side current 5 A)
|Note:||Short-circuit impedance should be less than 1 kΩ. (When the impedance is 0 Ω, drain current is approx, 7 mA. The opencircuit impedance should be more than 100 KΩ.)|
|Note:||Operating power supply input part and measured voltage input are not insulated to pulse input parts.So the input equipment must have the power supply transformer in which the secondary side is not grounded with the primary and secondary sides insulated, in order to prevent interference of the power supply circuit when connecting the external input circuit. Be sure not to use an auto-transformer.|
Since the transistor output is insulated from the internal circuit by a photo-coupler, it can be used both as a NPN output and PNP (equal value) output.
please make sure to check crimping terminal in dimensions page in each product page.
When using in the application confirming to EN61010-1/IEC61010-1, make sure to satisfy the following conditions.
|(1)||Pulse output part secure only basic insulation. In order to secure reinforced (double) insulation demanded by EN 61010-1/ IEC61010-1, secure basic insulation or more with load side and reinforced (double) insulation with communication system side.|
|(2)||Provide the voltage input part with an EN60947-1 or EN60947-3 compliant circuit breaker. The breaker that connects to the voltage input part must arrange at the position easily reached, and display shows it is the breaker of the equipment.|
|(3)||Use a wire with basic insulation or more for a wire cramped (or connected) CT.|
