5.2. Usage According to Purpose (Alarm, Periodic Active Energy, Rolling Demand, Operating Time, Password, etc.)

The following explains usage according to the purpose during operation.

 Display and operation of the upper/lower limit alarm

When the value exceeds the upper or lower limit setting value set in advance, the display flickers and alarm can be output. (For more information about how to set the upper/lower limit alarm, refer to page 34 and after.)

■ Alarm indicator

When the measurement element with an upper/lower limit alarm is displayed on the bar graph, "▲" flickers on the bar graph to indicate the upper/lower limit.

■ Behavior During Alarm Generation

Alarm condition: When measurement value exceeds alarm value, display flicker and an alarm contact closes. Alarm cancel: When alarm is canceled, display flickers normally and alarm contact opens.

Note: When the alarm delay time is set, an alarm is generated only when the alarm value is continuously beyond the upper/lower limit alarm value for the delay time.

6.3. Possible Setting Range for Maximum Scale

The maximum scale of current can be selected from about 40% to 120% of rating, and maximum scale of voltage can be selected from about 20% to 250% of rating, and maximum scale of active power and reactive power can be selected from about 20% to 120% of rating. But for the convenience of scale conditions, the values in the following tables are applied. Also, this is same as with corresponding measured values for maximum scale of analog output.

■Current maximum scale value

Possible setting range:-10 STEP to +3STEP of the rating Example: When the rating is 100A, the value is from 45A to 160A.

CAUTION

When the L side of CT circuit is common wire, it is necessary to short-circuit “C1”,”C2”,

Make sure that the electrical wires have the proper rating for current and voltage.

If the terminal wiring is pulled with a strong force, the input and output portion may detach.

If a pressure test is given to a hig h-pressure device, a ground m ust be used in order to Do not connect to Non-Connection (NC) terminals for the purpose of relay etc.

Use the proper voltage for the auxiliary power source terminal.

Installation 3. Wiring

Do not work with live wires

Do not connect terminal and RJ-45 connector with live wires. Do not insert and remove SD CRAD with live wires. It may cause electric shock, burns, device burn out, or fire. It is recommended that a protection fuse be used for VT and the auxiliary power source.

Do not open the secondary side of the CT circuit

Connect the CT secondary side signal correctly to the terminal for CT connection. If the CT is not connected properly or if the secondary side of the CT is open, it may result in high voltage on the secondar y side of the CT, the ins ulation of the secondar y winding wire may be damaged, and burnout may be caused.

Do not short the secondary side of the VT circuit

Connect the VT secondary side signal correctly to the terminal for VT connection. If the VT is not co nnecte d proper l y or if th e secon dar y side of the VT shor ts, over current may flow to t he secondary side of the VT, which can burn out the secondary winding wire. If the secondary winding wire burns out, it can damage the insulation of the primary winding wire, resulting in a short between phases.

Make sure connections to the connection terminals are tight

Electrical wires must be properly tightened to the connection terminal. Otherwise, heat and measurement errors may be caused.

Do not forget wiring of “C1”,”C2” and “C3” for pass.

Note for Input

1. The voltage input terminals for 3-phase 3-wire are different from those for others.

2. If the polarity for VT and CT are wrong, the measurement cannot be executed correctly.

Note

3. Do not connect wires to the NC terminals.

4. In the case of low voltage, there is no need for grounding of the se condary sides of VT and CT.

5. Always earth the terminal to the protective earth conductor. Earth the terminal with less than 100 ohm of earth resistance. Otherwise there will be a false operation.

Note for Output

1. Do not bunch pulse outputs, alarm outputs and digital inputs/outputs signal cables with the main circuit or power cables, or install them close to each other. Keep the distance between the inputs/outputs signal cables and the main circuit or power cables and high voltage lines shown below, when they run parallel to each other.

Note

2. Analog outputs signal cables should keep the distance from the other power cables and input signal (VT, CT and auxiliary power) cables, and should not be bunched. And use the shielded cables or twisted pair cables so that it is not affected the noise, serge, and induction. Also, the

3. The earthing has to be connected to earth by a thick wire of low impedance.

4. Keep the distance between MODBUS

5. Connect to earth the SLD terminal at one end.

1. As for CC-link cable, use the designated cable. (Refer to page 102.) Ver.1.10-compatible CC-Link dedicated cables, CC-Link dedicated cables (Ver.1.00) and CC-Link dedicated high-performance cables cannot be used together. If used together, correct data transmission will not be guaranteed. Also attach the terminating resister which matches the kind of the cable.

2. Connect the shielded wire of the CC-Link dedicated cable to “SLD” of each module, and ground both ends of the shielded wire using grounding via “FG”. The SLD and FG are connected within the module.

3. Because the CC-Link transmission line is a small signal cir cuit , it sho u ld b e separated from any strong-current circuit by 10cm or more. However, if it is laid parallel for a long distance, it must be laid at least 30cm away. The terminal must be grounded before using.

4. The CC-Link transmission line should use an exclusive line that meets the requirements for total wiring length, distance between stations, and termination resistance values according to the communication speed. If you do not use an exclusive line or observe the wiring requirements, communication may fail. (Refer to the “CC-Link Cable Wiring Manual” about the exclusive line and wiring requirements.)

5. Connect the supplied “terminal resister” to each module at both ends of the CC-Link system. Connect the terminal resistors between “DA” and “DB”.
