RE1

3091739-6A

Do not use this product where subject to flammable or explosive gas. This product is UL listed as Open Type, Listed Process Control Equipment and must be mounted in an enclosure. More than one disconnect switch may be required to de-energize the equipment before servicing. Signal inputs are SELV, limited energy. Caution - To reduce risk of fire or Electrical shock, Do not interconnect the outputs of different Class 2 circuits. Never disassemble, repair or modify the product. The life expectancy of the output relays varies greatly with the switching capacity and other switching conditions. Always use the output relays within their rated load and electrical life expectancy. If an output relay is used beyond its life expectancy, its contacts may become fused or burned. Use copper wire only 24-14 AWG stranded or solid. Torque screws to 0.74 to 0.90 Nm or 6.5 to 8 lb-in. Only two wires of same type and size per terminal. Correctly set the temperature controller settings to match the control target. If the settings are not compatible with the control target, the product may operate in an unexpected manner, resulting in damage to the product or an accident. To maintain safety in the event of malfunction of the temperature controller, we recommend taking safety measures, for example, installing an excessive temperature rise prevention alarm on a separate line. If malfunction prevents control, they may result in an accident. To reduce the risk of electrical shock or fire, install in a Pollution Degree 2 environment (controlled environment relatively free of contaminants). If the semiconductor (Triac) output is used and an excessive electrical surge or noise spike is impressed on the output terminals, a short circuit failure of the triac output is likely to occur. This could result in excessive current draw and possible fire. Use surge suppression to prevent excessive surges and fusing to help prevent an over current condition.

When the product is used under the circumstances or environment below, ensure adherence to limitations of the ratings and functions. Also, take countermeasures for safety precautions such as fail-safe installations.

* Use under circumstances or environment which are not described in the instruction manual.

* Use for applications where death or serious property damage is possible and extensive safety

precautions are required.

Check the wiring of inputs, disconnections, shorts and input type.

After the correction of A/D converter error, turn the power OFF then back ON again. If the display remains the same, the controller must be repaired. If the display is restored to normal, then a probable cause can be external noise affecting the control system. Check for external noise.

(1) This product is designed for indoor use only. Do not use this product in the following:

* Places directly subject to heat radiated from heating equipment. * Places subject to splashing liquid or oil atmosphere (exceeds NEMA 4X). * Places subject to direct sunlight, could discolor or cause excessive heat. * Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas). * Places where intense temperature changes exceed the published ratings. * Places subject to icing and condensation. * Places subject to vibration and large shocks.

(2) Use/store within the rated temperature and humidity ranges.

Provide forced-cooling if required.

(3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product. (4) Be sure to wire properly with correct polarity of terminals. (5) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. (6) Do not wire the terminals which are not used. (7) Allow as much space as possible between the controller and devices that generate a powerful

high-frequency or surge.

Separate the high-voltage or large-current power lines from other lines, and avoid parallel or

common wiring with the power lines when you are wiring to the terminals. (8) Use this product within the rated load and power supply. (9) Make sure that the rated voltage is attained within two seconds of turning the power ON. (10)

Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power

before starting actual control operations to ensure the correct temperature display.

(11) When executing self-tuning, turn the load and the unit ON simultaneously, or turn the load ON

before you turn the controller ON.

(12) Always turn power off. A switch or circuit breaker should be provided close to this unit.

The switch or circuit breaker should be within easy reach of the operator, and must be marked as

a disconnecting means for this unit. (13) If you remove the controller from its case, or put the controller into its case, never touch nor

apply shock to the terminals and the electronic parts inside. Make sure the electronic components and the case are not contacted when inserting the internal mechanism. Always ensure power is OFF when doing any maintenance on the controller or associated circuits.

(14) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the

outside of the product.

(15) Consider the 2 second delay required for the controller outputs to respond when you design your

control system. (16) If an option unit is used in the system refer to its Installation Manual before operating. (17)

The output may turn OFF when shifting to certain levels. Take this into consideration when performing

control.

(18) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently

overwriting data during communications or other operations.
