Prohibits changes to set values.
The burnout alarm function can be disabled by setting the set value to
“−”.
The burnout alarm function can be disabled by setting the set value to
“−”.
Sets the standard voltage used by the voltage fluctuation
compensation function. The fluctuation compensation function
operates in respect to this set value.
Returns all set values and measurement values to their default
settings.
Returns all set values to their default settings.
Returns all measurement values to their default settings.
Sets hysteresis for the alarm output value for burnout detection
(undercurrent) and heater layer short circuits (overcurrent) for CT1.
Sets hysteresis for the alarm output value for burnout detection
(undercurrent) and heater layer short circuits (overcurrent) for CT2.
Turns the gate input function ON and OFF. If the gate input is turned
OFF, application as a simple ammeter is possible.
Turns the voltage fluctuation compensation function ON and OFF.
Sets the lock time for the startup lock.
Sets the output delay time. Set this parameter to set the operating time.
Sets the soft startup time. Set this parameter only when using a soft
start function with the power regulator.
Turns the SSR short circuit detection function ON and OFF.
Turns the SSR open circuit detection function ON and OFF.
Turns the heater layer short circuit (overcurrent) detection function ON
and OFF.
alarms.
The heater layer short circuit alarm level is the same for both CT1 and
CT2.
Sets the control method of the cyclic/phase control heater.
Sets the CT for which to normally display the current.
Turns entering the power save mode ON and OFF.
Sets a 7-segment (NORM). full-span comparison (CMP), or bar (BAR)
display.
Sets the refresh time for the display.
Sets the unit number for RS-485 communications.
Sets the baud rate for RS-485 communications.
Sets the data length for RS-485 communications.
Sets the number of stop bits for RS-485 communications.
Sets the parity for RS-485 communications.
Sets the time from when the gate signal goes OFF until the burnout
alarm output turns OFF.
Sets the number of times the conductor for CT1 is passed through the
current transformer.
Sets the CT ratio for CT1.
Sets the number of effective digits to be displayed after the decimal
point for the CT1 current display.
Sets the number of times the conductor for CT2 is passed through the
current transformer.
Sets the CT ratio for CT2.
Sets the number of effective digits to be displayed after the decimal
point for the CT2 current display.
Sets the gate current value that stops an alarm, detection, or output.
(This setting is only valid when phase control is selected as the heater
control method.)
