Chart Paper for Standard Scale

* The chart paper has the same printed linear scale as the standard scale.

Therefore, it can be shared in regardless of input types (thermocouple, resistance thermometer, or others).

5. Restriction of digital recording/printing function

(1) The time necessary for data printing depends on the points of measuring input. 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

(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.

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

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.

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.

3. Power/protective conductor terminals wiring

 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.

 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.

Warning

Caution

After wiring, install the terminal cover.

4) Measurement input terminals wiring

 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.

Warning

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).

* 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 about1kv)

R: 100 to 150Ω (Rating about 1W)

(Minimum load) 100μA100mVDC

The following are precautions on wiring.

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

 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: About10mA
