Function
About three types of following functions (it changes by setting), it
can carry out by applying a voltage signal from
the outside.
Alarm reset
Alarm output is reset (output OFF).
Please refer to "4.3.6 Reset" about operation b
y the switch.
Maximum
/ Minimum value
reset
The maximum
/minimum value is reset (it u
pdates to the
instantaneous value at the time).
Please refer to "4.3.6 Reset" about oper
ation by the switch.
All reset
Resets all of the
alarm output and maximum/mini
mum value.
Please refer t
o "4.3.6 Reset" about
operation by the switch.
Minimum operation pulse width
300ms
, Continuation applying is possible.
Rated input
Input rating becomes the same as that of auxiliary supply.
AC100/110V 0.4VA
,
AC200/220V 1.4VA
,
DC100/110V 0.4W
AC DC two ways.
Contact capacity: About
3m
A (AC,
DC100/110V)
,
About
6mA (AC200/220V)
●
Caution on the use of external display selection input
External power consumption is 0.4VA at AC110V or 1.4VA at AC
220V
or 0.4W at DC110V.
In case a relay or a switch is used for power-supply supply, please use the thing
of about 1mA of the minimum application loads.
7. Maintenance and check
7.1 Trouble shooting
Symptoms
Possible causes
Remedial measures
Indicator does not
display.
The power supply is not supplied.
(Not connected. or voltage is low)
Check the auxiliary supply.
Again, a power supply is supplied.
Measurement display ON/OFF setti
ng is set to OFF.
Check the setting.
Trouble of device.
Replace the device.
Backlight does not
lights.
It is set as auto off or always-off.
Check the setting.
Have a margin of
measurement error.
Setting of a range is not right.
Please set again.
Setting of a input voltage is not right.
Check the setting.
Wiring is not right.
Check the wiring.
Outside the rated frequency (45 to 65Hz).
It cannot be used.
Cycle control, SCR phase angle control, PWM control, or
other inverter output is measured.
It cannot be used.
Communication error
occurs.
Communication cable is disconnection.
Or communication cable isn't connected justly. (Polarity,
etc.)
Check the communication cable.
Setting of communication isn't good.
(Address, Transmission rate, Parity, Stop bit)
Check the setting.
Pulse output is not
outputted.
Pulse output is set to OFF or measurement factor is set
to OFF.
Check the setting.
Alarm output does not
return.
The return method is a "manual reset".
Check the setting.
Settings changed.
It changed an input circuit or input voltage setting.
Please set again.
7.2
Check
Be careful with the following items periodically.
(1) Check if the measuring values, scale digits, units, etc. are displayed correctly.
(
2)
Check if LCD is free of a color change, breakage of case, or other defects.
(
3) Check the unit for loose wi
ring and loose mounting screws.
(4) Please remove, if dust has adhered to the product.
