International safety standards … The alarm output (option) with the “c” contact mechanical relay does

not conform to the following standards.

• IEC standards Conforms to safety class I (with PROTECTIVE CONDUCTOR TERMINAL)

and IEC1010-1 (OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2)

• Enclosure productivity Conforms to IEC529 (IP54)

• CE (EC Directive) EMC : Conforms to EN61326

Safety : Conforms to EN61010-1 +A2

• UL standards UL3111-1 (Approval pending)

WARNINGS

This paragraph covers important warnings for safety to be observed before reading the instructions. A full understanding of the following warnings is required. These warnings are important for the prevention of danger to human bodies as well as accidents with your recorder.

1. Switch and overcurrent protective device

Your recorder is not provided with a power switch or a replaceable overcurrent protective device. Prepare a switch and an overcurrent protective device (circuit breakers, circuit protectors or similar units) for the power supply within 3 m of your recorder in a location where you can reach easily. Use a switch and an overcurrent protective device conforming to IEC948-1 and IEC947-3.

2. Be sure to ground your recorder

Before turning on the power, connect the protective conductor terminal your recorder to the protective conductor of the power supply facility. Do not disconnect this wiring in running of your recorder to prevent an electric shock.

3. Before turning on the power

supply

In order to ensure safety, before turning on the external power switch, make sure that the power voltage is within the range indicated on the power supply label.

4. Don’t repair or modify your

recorder.

Make sure that a service engineer approved by the CHINO CORPORATION is ONLY permitted to repair or modify your recorder by replacing parts. Otherwise, it may be damaged or will not function correctly, or an accident such as an electric shock may result. For usual operation, it is not necessary to pull out an internal unit from a case.

Overcurrent protective device

(250V 3A)

Reference

The following fuse is mounted in the power supply unit of your recorder for safety use. However, this fuse is not replaceable.

5. Use your recorder in accordance with this instruction manual.

Use your recorder correctly and safely in accordance with this instruction manual. CHINO CORPORATION will

not be responsible for any injury, damage, lost profit or any other claim, which may result from its wrong use.

6.Turn off the power supply if an abnormal symptom occurs.

If any abnormal odor, noise or any smoke occurs, or if your recorder becomes too hot to be touched, turn off the power supply immediately and contact your local CHINO sales agent.

MAJOR FEATURES AND FUNCTIONS

Your recorder can record temperature and other various industrial variables on a 100 mm (if your recorder is AL3000) or 180 mm (if your recorder is AH3000) chart for 1 to 4 channels (depending on the number of pens).

(1) Trace printing by pens (2) Digital data printing to print measured values and other data

1 Features

Major features are shown below.

• Universal input. A range can be selected optionally for every channel from 10 DC voltage ranges, 36 thermocouple ranges and 11 resistance thermometer ranges.

• Universal power supply. The working voltage range is 100 to 240 V AC, 50/60 Hz.

• International safety standards…. CE: Conformance, UL and CSA (C-UL): Approval pending

• The basic operation should be carried out after programming range numbers and the trace printing range.

• You can execute all operation by the front keyboard without pulling out the internal unit. The internal unit

cannot be pulled out.

2 Functions

Major functions are shown below.

Display Printing

● Simultaneous display of the measured values for 1

to 4 channels.

● Analog indication of measured values for 1 to 4

channels with bargraphs.

● Six status lamps

● Switching the operation screens

(Measured value, Clock and Alarm Activation)

●Measured values blinks when alarm activates. (Note)

(Note) Programming of alarm is necessary. Alarm output is only available when your recorder is with the option

of “Alarm Output”.

● Trend tracing for 1 to 4 channels

● Fixed-time printing (time line, time, scale,

engineering unit, tag)

● Periodic data printing (Measured values are

digitally printed at preset intervals.) Digital data printing (Measured values are digitally

●

printed on demanding.) Message printing

●

On or off of time axis synchronization (POC)

Use a single-phase power supply having a stable voltage without any waveform distortion for the purpose of preventing wrong operations.

Warning

Prepare a switch and an overcurrent protective device (3 A) to the power supply for preventing an accidental electric shock during connection work. This instrument is not provided with any replaceable overcurrent protective device.

Warning

Make sure to turn off the power supply before connecting the power and the input/output terminals to prevent an electric shock.

2 Keep the input/output connections

away from high voltage power circuits

Don’t place the input/output cables close to or in parallel with any strong power circuits including power lines. Place the cables 50cm or more away from high voltage power circuits when they are placed close to or in parallel to other circuits.

3 Keep the thermocouple input away

from a heat source

For thermocouple inputs, keep the input terminals away from a heat source (a heating body) to reduce a reference junction compensation error. Don’t expose the input terminals to direct sunlight, etc.

4 Keep the input/output connections

away from noise source

Keep all connection cables away from noise source as far as possible, otherwise a malfunction may occur. Provide a solution if the cables cannot be separated from a noise source due to unavoidable circumstances.

Major noise sources Remedial measures

Electromagnetic switch, etc. Power line having waveform distortion, Inverter, Thyristor regulator

5 Use crimp style terminals

(1) Mount crimp style terminals for connection

cable terminations to prevent any looseness or disconnection of terminals or a short-circuit failure between terminals.

(2) Use the crimp style terminals with an

insulation sleeve to prevent an electric shocks.

6 Unused terminals

Don’t use any unused terminals for relaying, otherwise the electric circuits may be damaged.

Secure the connected

Warning

cables properly.

Secure the connected cables so as not to allow them to be hooked by a person or a substance, otherwise the connections may be cut and disrupted, and may cause an electric shock or other accidents.

Termination (unit: mm)

Insert noise filters between power terminals and input/output terminals. A CR filter is often used.

Use twisted cables for instrumentation as the input cables for the purpose of suppressing noise. For current inputs, mount shunt resistors (Section 16.2) to the channels to be measured before connections.

3 Connections of thermocouple inputs

Make sure to use thermocouple wires (or extension wires) to the input terminals of your recorder. If a copper wire is used halfway, a noticeable measuring error occurs. Don’t use a pair of thermocouple wires in parallel with other instruments (controller, etc.), otherwise a malfunction may occur.
