• OUT1: Control output 1 indicator

Lit when control output 1 is ON and not lit

when it's OFF. For a current output, lit for

greater than a 0% output.

• OUT2: Control output 2 indicator

Lit when control output 2 is ON and not lit

when it's OFF.

• STOP: control stop indicator

Lights when event input or “Run/Stop” is

stopped during operation.

During control stop, functions other than

control output are valid.

• CMW: communications writing enable/

disable indicator

Lights when communications writing is

“enabled” and is out when it is “disabled”.

• °C / °F : temperature unit

The temperature unit is displayed

when the configured display value is

a temperature.
When this parameter is set to "°C",
“C ” is displayed, and when set to
“ °F”, “F ” is displayed.
This flashes while ST(Self-Tuning) is

activated.

• : Protection indicator

Lit when Setting Change Protect is

ON (disables the Up and Down Keys).

• MANU: Manual output indicator

Lit when the Auto/Manual Mode is set

to Manual Mode.

• Insert the controller through the hole in the panel. Push the adapter on from the rear and

fasten temporarily, removing any gap between the controller, panel and adapter. Finally,
secure two mounting screws alternately keeping the torque to between 0.29 to 0.39 N•m.

• Make sure that the surrounding temperature does not exceed the allowable operating

temperature given in the specifications especially when two or more controllers are mounted.

Input error

(S. Err)

(E111)

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

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.

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.

For detailed operating instructions, please refer to the 900-TC16 User's Manual
(900-UM007_-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

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.
This product is UL listed as open type 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.
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).
Set the configuration parameters of the controller and test them to ensure they are suitable for the
application being controlled. If not properly configured unexpected operations may occur resulting in
property damage or accidents.

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.

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.
・This is a class A product.
In residential environment areas it may cause radio interference, in which case the user may be required to take adequate measures to
reduce interference.

(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 (Excceds 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 controller 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 relay 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.

(16) 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.

(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.
