Wiring
4~20mA Current Input Signal
This is frequently used operation for control. Control signal is 4~20mA dc current.
Maximum output voltage is limited by external V.R or OUt parameter value.
Note 1) In case of connect external V.R, keep the terminals number.
Note 2) If connect external V.R, at G1, G2, and G3 terminal, disable internal parameter OUt automatically.
Alarms
1 Over Current Alarm and Relay Operating
Alarm operating when the measured R, T phase current average current the set upper limit parameter symbol: CLm). Over current limit Execute the following three alarm / control operations according to the operation mode (parameter symbol: Cmd).
1) Alarm Only: Current Limit LED and relay turn on.
2) Output Off: Power output will be off. Current limit LED will be blink.
For restart, press [RST] Key after trouble shooting.
3) Control: The output current is forcibly reduced to the current upper limit value or lower. Output voltage drop may occur.
2 Partial Line Failure
Alarm operating when at least one of the input power (R, S, T) is broken.
The following two alarm / control operations are performed according to the line failure alarm operation mode (parameter symbol: Pmd).
1) Alarm Only : Power error LED and relay turn on.
2) Output Off : Power output will be off. Power error LED will be blink. For restart, press [RST] Key after trouble shooting.
3 Load-unbalance
R and T phase current difference of more than 30%. (operating only 5A over)
4 Load Break, Un-Load
If the input or output limit setting is not 0 and the time given by the LBA variable has elapsed R phase, and T phase output current average is 2.5A or less.
Check below point.
(1) Unload
(2) Connection
(3) Broken Fuse
(4) Broken SCR Element
5 Over Temperature of SCR
It occurs when the temperature of the control element (SCR) exceeds 80℃.
According to the overheat alarm operation mode (parameter symbol: tmd), the following two alarm / Conduct.
1) Alarm Only: Over Temp. LED and alarm turn on.
2) Output Off: Power output will be off. Over temp. LED will be blink. For restart, press [RST] Key after trouble shooting.
