Chapter 1 Overview
1-1 General
The LCR10 is a microprocessor based 10 inch circular chart recorder. Programmable alarm options combined with “ease of setup” provide the fl exibility required for a multitude of recording applications.
The Ink style LCR10 is the fi rst recorder with “self documenting” confi guration during initial setup. It can operate using standard or competitive charts. The battery backup feature provides up to 48 hours of recording in the event of a power loss, providing an additional degree of protection for customer processes.
A unique setup template provides the user with an “on the spot” manual. This setup template will also self document the current setup for quick review by an operator.
These units are powered by a fi eld selectable 110/220VAC 50/60Hz. supply. A 9 Volt battery allows for operation for up to 48 hours if the main power supply fails. Standard inputs are programmable for thermocouple types J, K, T, R, B and S as well as 4-20mA or 0-5 VDC.
Optional alarm relay is available and programmable for low, hi, or band in latching or non-latching operation.
High accuracy, maximum fl exibility, fast response and a simple interface are the main benefi ts of the LCR10 recorder.

Chapter 2 Installation
Dangerous voltages capable of causing serious injury or death are sometimes present in this instrument.
Before installation or beginning any troubleshooting procedures, the power to all equipment must be switched off and isolated. More than one power disconnect may be required.
Units suspected of being faulty must be disconnected and removed to a properly equipped workshop for testing and repair. Component replacement and internal adjustments must be made by a qualifi ed maintenance personnel only.
To minimize the possibility of fi re or shock hazards, do not expose this instrument to rain or excessive moisture.
Do not use this instrument in areas under hazardous conditions such as excessive shock, vibration, dirt, moisture, corrosive gases or oil. The ambient temperature of the areas should not exceed the maximum rating specifi ed in Chapter 5.
2 - 1 Unpacking
Upon receipt of the shipment remove the unit from the carton and inspect the unit for shipping damage.
If any damage due to transit , report and claim with the carrier. Write down the model number, serial number, and date code for future reference when corresponding with our service center. The serial number (S/N) and date code (D/C) are labeled on the box and the platen of the unit. Make sure that all items are accounted for: 1: Battery (for battery backup) 2: Installation manual
2 - 2 Case Location
Upon unpacking, fi nd a suitable location to mount the recorder before wiring power to the unit.
Select a location that is well lighted, free form dust, dirt, or corrosive fumes. The recorder should not be located near any sources of heat or be subjected to sudden or extreme temperature changes. It should be
mounted on a rigid support that is not subject to vibration.
2-3 Mounting
Make panel cutout to dimension shown in Figure 2-1.
Install both mounting clamps and insert the case into the panel cut out.

2-4 Wiring Precautions
Before wiring, verify the label for correct model number and options. Switch off the power when checking.
Care must be taken to ensure that maximum voltage rating specifi ed on the label are not exceeded.
It is recommended that power of these units to be protected by fuses or circuit breakers rated at the minimum value possible.
All units should be installed inside a suitably grounded metal enclosure to prevent live parts being accessible from human hands and metal tools.
All wiring must conform to appropriate standards of good practice and local codes and regulations. Wiring must be suitable for maximum voltage, current, and temperature rating of the system.
Take care not to over-tighten the terminal screws.
Unused control terminals should not be used as jumper points as they may be internally connected, causing damage to the unit.
Verify that the ratings of the output devices and the inputs as specifi ed in Chapter 5 are not exceeded.
Electric power in industrial environments contains a certain amount of
noise in the form of transient voltage and spikes. This electrical noise can enter and adversely affect the operation of microprocessor-based controls. For this reason we strongly recommend the use of shielded thermocouple extension wire which connects the sensor to the unit. This wire is a twisted-pair construction with foil wrap and drain wire. The drain wire is to be attached to earth ground at the sensor end only.
