2-4. Wiring
When making wire arrangement, be sure to cut the power
supply OFF. There is a risk of electric shock.
Make sure the protective conductor terminal (
) is
grounded. Otherwise, a serious electric shock may result.
After completing wiring arrangement, do not touch the
terminals and electrically charged parts while power is ON.
(1)Arrange wiring according to the terminal layout in item 2-5
and the terminal arrangement table in item 2-6. Confirm
that all connections are made correctly.
(2)Use crimp-style terminals of 7mm or narrower width to meet
M3.5 screws.
(3)In case of thermocouple input, use a compensation wire with
the type of thermocouple selected. The external resistance
should be100 or less.
(4)In case of R.T.D. input, the resistance value per lead wire
should be 5 or less and all the 3 wires should have the same
resistance value.
(5)Avoid arranging the input signal line to pass through in the
same conduit or duct with high-tension circuit.
(6)Shield wire (one-point grounding)
is effective to eliminate
the electrostatic induction noises.
(7)An effective way of eliminating the magnetic induction
noises is to twist the input wire in short and equal intervals.
(8)For source power connection, use wire or cable having a
cross section of 1mm
2
or larger and performance capacity
equivalent to 600V vinyl insulation wire.
(9)Grounding wire should have a cross section of 2mm
2
or
larger and the grounding work should ensure ground
resistance of 100 or less.
(10)Screw up the terminal connection securely.
Tightening torque 1.0N·m (10kgf·cm)
(11)Noise filter
In case the instruments are affected by the power supply
noise, install a noise filter to avoid operation errors.
Mount the noise filter on the grounded panel and connect the
noise filter output and the power supply terminal of the
indicator with shortest possible distance.
Recommended noise filter: TDK product ZMB2203-13

: Display part for measured value (red)
Mode 0, Current PV value is displayed on the basic screen.
Type of parameters is displayed on each parameter
character screen.
Set value is displayed on each parameter setting screen.
: LED for monitoring
(1)AL1 (Alarm 1) output monitoring LED (red)
LED lights when an assigned alarm is ON.
(2)AL2 (Alarm 2) output monitoring LED (red)
LED lights when an assigned alarm is ON.
(3)SET (parameter setting) monitoring LED (green)
LED lights when screen display is other than the basic
screen.
(4)COM (communication) monitoring LED (green)
LED lights when communication mode is on remote
control.
: Key switch operating part
(1)
(Parameter key)
By pressing this key, display changes from a screen to
the next in each screen group.
By pressing this key for 3 seconds or longer, the key
works as the shifting key to shift the screen from the
basic screen of Mode 0 screen group to the initial
parameter screen of Mode 1 screen group.
(2)
(down) key
By pressing this key on each screen, the decimal point
of the last digit blinks and the data value is decreased
or the decimal point shifts downward.
(3)
(up) key
By pressing this key on each screen, the decimal point
of the last digit blinks and the data value is increased or
the decimal point shifts upward.
(4)
ENT
(entry/register key)
This key works for mutual shifting between the
parameter character display screen and the parameter
setting screen. (when light of the decimal point of the
last place is OFF)
On each screen of Mode 0 and Mode 1 screen groups,
the data changed by the
or
key is
established. (when light of the decimal point of the last
place is also OFF)
