1.1 Features

Chapter 1 FEATURES AND FUNCTIONS

1.1 Features

This chapter describes the main features and functions of the µR1800 recorder. The µR1800 is equipped with all the functions which can be expected in a modern recorder,

whereas its functions also reflect the latest user requirements.

The µR1800 recorder is a precision measuring instrument that is equipped with many outstanding features:

Compact sized, high reliability: Its compact size (depth 220mm) allows you to install the µR1800 where only a limited space is available. In case of the pen model, a contact-free potentiometer and a brushless-DC servomotor contribute to its high reliability. In case of the dot printing model, high reliability is obtained by the use of high break down voltage solid-state relays.

Universal inputs: Inputs like DC-voltage, Thermocouple (TC), Resistance Temperature Detector (RTD), and Digital Input (contact) can all be conveniently used. There is no need to change any dipswitches; the type of input can be set using the keyboard.

Easy interactive setting: The setting procedure has been made very easy, by using only panel keys. The µR1800 asks you to select the desired settings, without the need for remembering difficult setting-codes.

Large informative operator display: The large sized, VFD, display shows the measured data (including the engineering units) or clock, and bargraph at the same time. There are two types of bargraph available: percentage-display, and center-zero display. Because of its 1%-resolution, the bargraph displays very accurately.

1. FEATURES AND FUNCTIONS

Continuous pen recording for up to four channels (pen model only):

Depending on your µR1800 model type, the µR1800 can measure up to four channels simultaneously. This allows you to decrease the number of recorders you require.

Universal power supply (except for /P1 model): The µR1800 accepts 90 to 250VAC (except 132 to 180VAC), and 50/60Hz without any problems, or need to turn switches. Therefore the µR1800 is compatible with a wide variety of power supplies.

High performance: The sampling speed of the µR1800 pen model is high at 125 ms, whereas the recording cycle of the µR1800 dot printing model is 6 ch./10 seconds, or 12ch./15sec., 18ch./20sec. or 24ch./30sec. depending on the model. The µR1800 is equipped with many functions. Special functions can be ordered as an option. Furthermore, its power consumption is low (4pen model; 30VA under normal operation conditions).

Easy maintenance: Because of the use of many contact-free parts, the need for maintenance has been decreased. The µR1800 is designed in modules, which decreases the time needed for maintenance extensively.

Closed case: The closed case of the µR1800 allows it to be used in many environments. The front door is in accordance with DIN 40050-IP54.

Computer interface and memory card: If equipped with this option, the µR1800 can store and retrieve measured data as well as setting data, using an IC memory card or directly from your PC. The available interface is RS-422-A.

IM 4H3B1-01E

Based on international safety standards: The µR1800 (except portable type) is based on international safety standards, such as the IEC 348.

3. INSTALLATION

WARNING

To prevent an electric shock, ensure the main power supply is turned OFF and connect the ground terminal using a class 3 resistance of 100Ω or less. For power and ground wiring termination, use “crimp on” lugs (for 4mm screws) with insulation sleeves (see figure 3.5). To prevent fire, use 600V PVC insulated wire (AWG18) for power and ground wiring (cross sectional area of 0.83mm2 or thicker, anti-galvanic corrosion finish, insulation thickness should be more than 0.8mm, insulation resistance should be more than 50MΩKm at 20°C, approved EN60 320 (VDE0625), and do not remove the transparent cover. Make sure to apply a power switch in the power supply cord with the following characteristics: Others than /P1 model

• rated power current > 1A

• rated rush current > 60A

• fuse(s) of 2A to 15A is (are) necessary.

/P1 model

• rated power current > 3A

• rated rush current > 70A

• fuse(s) of 5A to 15A is (are) necessary.

The power switch and fuse used in the power supply cord should be

• CSA approved (for use in North America)

• VDE approved (for use in Europe).

3.2.3 Input Wiring

1 Make sure the power switch is turned OFF and remove the transparent cover at the

rear of the µR1800.

2 Connect the input wires to the input terminal. 3 Replace the transparent cover.

It is recommended that “crimp on” lugs (for 4mm screws) with insulation sleeves be used for leadwire ends. See figure 3.5.

Figure 3.5 “Crimp on” Lugs

In case of clamped input terminals, do not use “crimp on” lugs.

Since the input terminal will be affected by changes in temperature (e.g. because of wind), make sure to replace the transparent cover after wiring. Even after replacement, take care not to expose the terminals to fans, etc. Suggestions to minimize noise pickup:

• The measuring circuit wiring should be run as remote as possible from the power and ground wires.

• It is recommended that shielded wires be used to minimize noise pickup from an electrostatic induction source. The shielding wire of the cable should be connected to the µR1800 ground terminal (only one ground line).

• To minimize noise from an electromagnetic induction source, twist the measuring line cables in short and equal spaces.

• The to be measured object should be free from noise. However, if it isn’t, make sure the measuring circuit is isolated and the to be measured object is grounded.

WARNING

CAUTION

If TC and RJC is used, the temperature of the input terminals should be as stable as possible. Therefore, make sure to use the transparent cover. The thermal capacity of the wiring should be small (recommended ø ≤ 0.3mm). Refrain from wiring the input parallel. However, if you do, then

• do not use the burnout function

• ground the equipments at the same point

•turning ON/OFF the power might cause malfunction

• RTD cannot be wired parallel.

To prevent an electric shock, ensure the main power supply is turned OFF and connect the ground terminal using a class 3 resistance of 100Ω or less.

If you have an input of DC ≤ 2V or a TC, don’t apply an input voltage exceeding ±10VDC. Do not apply a max. common mode voltage more than 250VAC rms (50/ 60Hz). The recorder and measured values will be adversely affected. Add following to 'CAUTION' This instrument complies with Inatallation Category ll.

NOTE To prevent an emission of electromagnetic disturbances, separate the input wires from

the other wires at least 0.1m. Over 0.5m is recommended.
