For detailed operating instructions, please refer to the 900-TC16 User's Manual
(900-UM007A-EN-E).
It can be found online at http://www.ab.com/manuals/.
Indicates information that, if not heeded, could result in injury,
damage to the product, or faulty operation.
ATTENTION
ATTENTION
Devices are 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.
Disconect power to device before installing or servicing.
Do not touch the terminals of controller when voltage is applied.
Do not allow metal fragments or lead wire scraps to fall inside this product. This may cause electric
shock, fire or malfunction.
Do not use this product where subject to flammable or explosive gas.
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).
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.
(1) ±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) When executing self-tuning, turn the load and the unit ON simultaneously, or turn the load ON
before you turn the controller ON.
(11) 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.
(12) 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.
(13) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the
outside of the product.
(14)±Consider the 2 second delay required for the controller outputs to respond when you design your
control system.
(15)±If an option unit is used in the system refer to its Installation Manual before operating.
NOTICE
· Since the voltage output (control output 1) is not electrically insulated from the internal wiring, one or other of the control output
terminals must be left unearthed when using an earthed (grounding) type thermocouple. (Connection makes measurements unreliable
due to ground loop currents.) Basic insulation is provided between the voltage outputs (control output 2) and internal circuits.
· Basic insulation is provided between power supply, input, output and communications (for applicable models). If double insulation is
required provide supplemental insulation as defined by IEC60664.
