5. Restriction of digital recording/printing function

(1) Data printing requires approximately two minutes. Note that when data printing is executed, the trace printing

stops until the printing is finished.

(2) When the chart speed is set to 251mm/H or more, power-on printing, data printing, list printing, and printing

function for other than time line are disabled.

(3) The trace printing executes dot printing with five seconds interval (standard); however, if time printing is

executed during the trace printing, the dot interval may become longer. The dot interval is extended with the
inserted printing. Therefore, this is not abnormal.

(4) Printing is formed with dots of one pin. Therefore, if the power is turned off while characters are being formed,

they cannot be formed correctly. This is not abnormal.

2. Precautions on wiring

Precautions on wiring are described below. Observe them to maintain safety and reliability.

1) Feed power source
For the power source for the unit, use the single-phase power source with stable voltage and without
waveform strain to prevent malfunctions.

(1) Switch and overcurrent protective device

Add a switch and overcurrent protective device (250V,3A) to the feed power source
to prevent an electric shock on wiring. The unit has no replaceable fuse.

(2) Connect after the power source is turned OFF

When performing power and input/output wiring, make sure to turn OFF the feed
power source to prevent an electric shock.

2) Separate from strong power circuits
For input/output wiring, avoid adjacency or parallel with strong power circuits such as power lines. Separate
50cm or more for adjacency or parallel.

3) Separate thermocouple input from heat sources.
To reduce reference junction compensation errors for thermocouple input, especially separate terminals
from heat sources (heating body). Also, avoid radiation such as direct sunlight.

4) Separate from noise sources.
Separate from noise sources as much as possible. Unexpected troubles may occur. If separation from
noise sources is disabled, implement countermeasures.

Main source

Countermeasures

 Electromagnetic switch or others
 Power line with distortion of wave
 Inverter
 Thyristor regulator

Insert noise filters between power source and input/output
terminals. CR filters are used in many cases.

!

Warning

- 13 -

5) Use crimping terminals.
(1) To prevent looseness or disconnection of terminals and short circuit between terminals, install

crimping terminals to termination of connection cables.

(2) To prevent an electric shock, use crimping terminals with insulation sleeves.

1) Power/protective conductor terminals

 Turn OFF feed power source.

Before power/protective conductor terminals wiring, make sure to turn off the feed power
source to prevent an electric shock.

2) Power terminal wiring
Using 600V vinyl insulated cables as the power line,
install crimping terminals with insulation sleeves to the
termination for wiring.
Note: Use the following standard cables.
(1) IEC 60227-3
(2) ANSI/UL817
(3) CSA C22.2 No.21/49

3) Protective conductor terminal wiring
Make sure to connect to the protective conductor of the

 mark at power terminals

After wiring the power terminals have power supply voltage applied. Make sure to install
power terminal covers after wiring to prevent an electric shock.

 Pay attention to power supply voltage and noise.

The power supply voltage of the unit is indicated on power terminals. Applying power
other than the indicated one causes accidents or malfunction. In addition, if the power
has noise interference, implement countermeasures such as noise cut transformer
installation.

4) Measurement input terminals wiring

1) Measurement input terminal
Turn OFF the feed power source before
wiring to prevent an electric shock.
Install crimping terminals with insulation
sleeves to input terminals for wiring.

2) DC voltage (current) input wiring
Use instrumentation twisted cables for
measures against noise as input cables.
For current input, connect the shunt resistor
for current input to the channel to be
measured before wiring.

3) Thermocouple (TC) input wiring
Make sure to wire thermocouple cable (or
compensation lead wire) to input terminals of
the unit.
If a copper conductive wire is connected
halfway, big measurement error will be
generated.
In addition, avoid parallel connection of a pair
of thermocouple wires with other instruments
(controller or others) that causes troubles.

4) Resistance thermometer (RTD) input wiring
To prevent measurement errors, use 3-core
cables as the input cable in which lines have
the same resistance.
In addition, one resistance thermometer
cannot be connected in parallel with other
instruments (a controller or others).

 mark on measurement input terminals

High voltage may be applied to the measurement input terminals due to common mode
noise. Allowable noise value is 30VAC or 60VDC or less. Check that the voltage is equal
to or less than the allowable value. Install terminal covers after wiring to prevent an
electric shock and protect input cables. For thermocouple input, installing terminal
covers reduces reference junction compensation errors.

2) Wiring
Turn OFF the feed power source and the power source for buffer relay before wiring to prevent an electric
shock.
(1) Wire the cable to the load via the buffer relay.
(2) To the alarm output terminals, type O crimp style terminal with insulation sleeve which is connected to

double insulated signal wire should be connected. ( Refer to P13 )

Mechanical relay ‘a’ contact output example

Mechanical relay ‘c’ contact output example

* N.C terminal is opened on alarm occurrence in opposite way to N.O terminal.

 mark on alarm output terminals

Maximum of 240VAC can be connected to the alarm output terminals of this unit.
Basic insulation (dielectric strength 1390V) is carried out between the alarm output

channels, however, from the malfunction etc. 240VAC may be output to each alarm
output terminals. Double insulation or reinforced insulation to the outside circuit
connected to an alarm output terminal should be set.

A buffer relay power supply is applied to the alarm output terminals after connections
and so creates a risk of electric shock if touched. Terminal cover must be mounted after
connection. Moreover, safety measures to the outside circuit should be set.

 Implement safety measures.

The alarm output of the unit may generate output failure with wrong operation, failure,
abnormal input, or others. Double insulation or reinforced insulation in outside circuit side
of all the channels should be set in any system for safety ensuring.

Contact protective element
Z installation

 Install the contact protective element which fits the buffer relay.
 It is effective to install the element to the coil side of the buffer relay (see the figure

of mechanical relay ‘a’ contact output example) and prevents wrong operation with
light load.

Selection of buffer relay

 Coil rating: Contact capacity or less of output terminals
 Contact rating: Double of load current or more

In addition, the coil surge absorption element built-in type relay is recommended. If
there is no buffer relay which meets the load rating, implement another stage of buffer
relay.

Selection of contact
protective element

If there is no surge absorption element built-in buffer relay, install this element.
The element of C/R (capacitor + resistor) is general.
<C/R standard> C: 0.01μF (Rating about 1kv)

R: 100 to 150Ω (Rating about 1W)

6. Remote contacts terminals wiring and operation selection (option)

Only with remote contacts terminals (option).

1) Remote contacts terminals

2) Wiring
Turn OFF the feed power source before wiring to
prevent an electric shock.
(1) Use no voltage contact signals to be given to the

remote contacts terminals.

(2) Install crimping terminals with insulation sleeves

to remote contacts terminals for wiring.

 No voltage contact

For contacts connected to the remote contacts terminals, use switches or relays driven
with voltage level 30VAC or 60VDC or less or manual contacts which support light
load.

■ Wiring example

 Voltage on contact open: About 5V
 Current on contact short: About 10mA
