Series B Controllers
Series B Upgrades
Series B controllers have the following upgrades.
900-TC8x
Although the upgraded controllers are compatible with the previous
controllers, terminal arrangements have been changed. Terminal sizes and
panel mounting depth have not been changed.
Other changes are outlined in the following tables. Refer to the relevant pages
in the manual for details.
900-TC16x
The upgraded controllers are basically compatible with the previous
controllers. Terminal arrangements, terminal sizes, and panel mounting depth
have not been changed.
900-TC32x
Model numbers have changed accompanying the introduction of universal
input capability. The default setting of the input type parameter of the
900-TC32x (models with resistance thermometers) has been changed from a
Pt100 resistance thermometer to a K thermocouple. Make sure the setting of
the input type parameter agrees with the temperature sensor that is being used.
The terminal block has also been changed, which means the wiring methods
and terminal arrangement are different.

Features
• Watertight construction (equivalent to IP66 indoor use).
• Conform to cULus/IEC safety standards and EMC standards.
Main Functions
The following introduces the main functions of the Bulletin 900-TC8,
900-TC16, and 900-TC32 temperature controllers. For details on each
function and how to use them, refer to Chapter 3 and onward.
• Input Sensor Types — The following input sensors can be connected
for temperature input:
– Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PL11
– Infrared non-contact temperature sensor type: Type K thermocouple
(10…70XC), K (60…120XC), K (115…165XC), K (160…260XC)
– Platinum resistance thermometer: Pt100, JPt100
– Analog millivolt input: 0…50 mV
• High level analog inputs:
– Current input:4…20 mA DC, 0 to 20 mA DC
– Voltage input:1…5V DC, 0…5V DC, 0…10V DC
• Control Output — Control output is either an On/Off
electro-mechanical relay (EMR) ON/OFF triac output (AC only)
On/Off voltage (input to solid-state relay) output, or analog current
(DC: 4...20 mA or 0…20 mA) output
• Triac Relay Outputs
closing andopening the AC voltage circuit, thereby eliminating relay
chatter and arcing and improving durability versus an EMR. However, if
high levels of noise or surge are imposed between the output terminals,
short-circuit faults may occasionally occur. If the triac output becomes
permanently shorted, there is the danger of fire due to overheating of
the heater element. To avoid this danger, design safety into the system,
including measures to prevent excessive temperature rise and fire. Take
countermeasures such as installing a surge absorber. As an additional
safety measure, provide error detection in the control loop. Use the
Loop Break Alarm (LBA) and Heater Short Alarm (HSA) that are
provided for Bulletin 900 temperature controllers.

If necessary, a more comprehensive alarm function can be achieved by
configuring the Standby Sequence, Alarm Hysteresis, Close in
Alarm/Open in Alarm and Alarm Latch ON/OFF parameters.
When the input error output is configured to ON, Alarm Output 1
turns ON when an input error occurs.
• Control Adjustment — Optimum PID constants can be configured
easily by using the AT (Auto-Tuning) and ST (Self-Tuning) parameters.
• Event Input — When the optional event input unit is mounted, the
following functions can be achieved by event input:
Multiple set point selection (multi-SP max. 4 points), RUN/STOP
mode change switching between automatic and manual operation, and
starting/stopping the simple program. Refer to Table 1.C and 1.E.
• HBA and HS Alarms — The Heater Burnout Alarm (HBA) and
Heater Short Alarm (HSA) and heater overcurrent function is
supported by selecting the appropriate controller (900-TC8) or option
module (900-TC16). Refer to Table 1.B for the TC8 and Table 1.E for
the TC16.

ATTENTION
!
• Horizontal group-mounting of two or more temperature controllers, or
mounting temperature controllers above each other may cause heat to
build up inside the temperature controllers. This will shorten their
service life. When mounting temperature controllers like this, consider
forced cooling measures, such as a cooling fan.
• If forced air cooling is used, limit cooling to the terminal block. Rapid
variation or transients in temperature at the terminal block may result in
a measurement error.
System Wiring and Installation Guidelines
Risk of Electrical Shock
• 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.
• To reduce risk of fire or electrical shock, do not
interconnect the outputs of different Class 2 circuits.
• Disconnect all power (including field device) before
installing and/or servicing.
• Do not touch the controller’s wiring terminals while
the power is ON. Doing so may cause an electric
shock.

Wiring Guidelines and Precautions
• Do not wire unused terminals.
• Make sure to observe correct polarity when wiring the
controller terminals.
• To reduce induction noise, 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. We recommend using
separating pipes, ducts, or shielded lines.
• Allow as much space as possible between the
Bulletin 900 Controller and devices that generate
powerful high-frequency noise (e.g., high-frequency
welders, high-frequency sewing machines) or surges.
• Separate input leads and power lines in order to protect the
Bulletin 900-TC8, 900-TC16, 900-TC32, and its low voltage sensors
(e.g., thermocouple) lines from external noise.
• For 900-TC32: Use a shielded AWG24 to AWG18 (cross-sectional area
of 0.205 to 0.823 mm2) twisted-pair cable. The stripping length is
6 to 8 mm.
• We recommend using solderless lugs when wiring to the
Bulletin 900-TC8 and 900-TC16 screw terminals. However, if lugs are
not used, the controller’s screw terminals will accept two solid or
stranded wires (no mixing) between 24 (0.205 mm
2
mm
)AWG. Wire strip length 5...6 mm.
• For 900-TC8 & 900-TC16: Tighten the terminal screws properly.
Tighten them to a torque 0.74…0.9 N•m (6.6…8 lb-in.) Loose screws
may cause malfunction. For 900-TC32: Tighten the terminal screws to a
torque of 0.5 N•m
• Use the type of solderless lugs referenced in Figure 2.18 for your proper
Bulletin type.

Power Supply
The controller requires an external power source for operation. For the
900-TC8 connect to terminals 1 and 2 and for the 900-TC16 connect to
terminals 9 and 10. The following table shows the specifications.

Use a power supply matched to the power specifications of
the Bulletin 900 Controller. Also, make sure that rated
voltage is attained within 2 seconds of turning the power
ON.

When mounting a noise filter on the power supply, make sure to first check the
filter’s voltage and current capacity, and then mount the filter as close as
possible to the Bulletin 900 Controller. Reinforced insulation is applied to the
power supply I/O sections.

Input/Sensor Wiring Considerations
• When the thermocouple leads are extended, make sure to use shielded
thermocouple extension wire matched to the type of thermocouple.
• For a thermocouple, make sure to follow the polarity color code convention.
• If there is a large error in the measurement values, make sure that the correct
sensor type is configured and for thermocouples that input compensation has
been properly configured.
• RTDs can be either 2- or 3-wire types. If a 3-wire type is used, the controller
provides lead wire resistance compensation up to 5 Ω resistance. If using 24
AWG lead wire, this is approximately 59 m of wire. Use larger gauge wire if
longer length is required.
• For RTDs, the controller source is approximately 1 mA of current.
• If a cooling fan is used in the panel enclosure, prevent only the terminal
block from being cooled when using thermocouples. Otherwise, this may
result in a measurement error.

• To reduce induced electrical noise, the leads on the temperature controller’s
terminal block must be wired separately from large-voltage/large-current
power leads. Also, avoid wiring leads in parallel with power leads or in the
same wiring path. Other methods such as separating conduits and wiring
ducts, or using shield wire are also effective and recommended.

Output Wiring Considerations
• Do NOT connect a DC load to the Triac (AC) relay.
• The PNP voltage (SSR) output (Control Output 1) is not electrically
isolated from the controller’s internal circuits. SSR Control Output 2 of
the 900-TC16 is also not isolated. However, SSR Control Output 2 of
the 900-TC8 is isolated. When using a grounded thermocouple, do not
connect any control output terminals to earth ground. If the control
output terminals are connected to earth ground, errors will occur in the
measured temperature values as a result of ground loop leakage current.
• For 900-TC8 & 900-TC16: The 4...20 and 0…20 mA analog output is
electrically isolated from the other controller circuits as follows:
– Analog Output to Sensor Input: 500V AC 50/60 Hz for 1 minute
– Analog Output to Alarm Output: 2000V AC 50/60 Hz for 1 minute
– Analog Output to Input Power Supply: 2000V AC 50/60 Hz for 1
minute
• The life expectancy of the electro-mechanical relay outputs vary 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 the Bulletin 900 Controller within the rated load. Not doing so may
cause damage or fire.
• Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids, magnetic
coils, or other equipment that have an inductance component).
• About 4 seconds are required for control and/or alarm outputs to turn
ON when the power is initially turned ON to the controller. Take this
into consideration when the temperature controller is incorporated into
a sequence circuit.
• For 900-TC8 & 900-TC16: Triac (AC) relay outputs use
semiconductors for switching when closing and opening the circuit,
thereby eliminating relay chatter and arcing and improving durability
compared to an electro-mechanical relay output. However, if high levels
of electrical noise or surge are imposed between the output terminals,
short-circuit faults may occasionally occur. If the output becomes
permanently shorted, there is the danger of fire due to overheating of
the heater. Design safety into the system, including measures to prevent
excessive temperature rise and fire. Take countermeasures such as
installing a surge absorber. As an additional safety measure, provide
error detection in the control loop. (Use the Loop Burnout Alarm

• Always connect an AC load to a Triac (AC) relay output. The output will
not turn OFF if a DC load is connected.
• A voltage output (control output) is not electrically isolated from the
internal circuits. Therefore, when using a grounded thermocouple, do
not connect any of the control output terminals to earth ground. If
control output terminals are connected to ground, errors will occur in
the measured temperature values as a result of ground loop leakage
current. With 900-TC8, however, voltage output (Control Output 2) is
functionally isolated from the internal circuits.
• Control Output 2 of the 900-TC16 is a voltage output (SSR driver) only,
and outputs across terminals 11(+) and 12(-), or 14(+) and 15(-).
• Control outputs 1 and 2 (voltage outputs) are not isolated.
• Triac (AC) relay outputs use semiconductors for switching when closing
and opening the circuit, thereby eliminating relay chatter and arcing and
improving durability compared to an electro-mechanical relay output.
However, if high levels of electrical noise or surge are imposed between
the output terminals, short-circuit faults may occasionally occur. If the

How Function Groups Are
Configured and Operating
the Keys on the Front Panel
Parameters are divided into control categories, each called a function group.
Each of the items/values that can be configured in these function groups is
called a parameter. The function groups on the Bulletin 900 controller are
divided into the following:
To activate the Advanced Setting function group, set the Protect function group of the Initial/Communications
Protect to 0.
Indicates items that can be configured.
—
Of these control categories, the Initial Setting, Communications Setting,
Advanced Setting, and Calibration function groups can be used only when
control has stopped. Note that controller outputs are stopped/reset when any
of these four function groups are selected.
• Protect Function Group — To move to this function group,
simultaneously press the
O and M keys for at least 3 seconds in the
Operation, Adjustment, or Monitor/Setting Item function group. This
function group is used to prevent unwanted or accidental modification
of parameters. Protected parameters will not be displayed, and so the
parameters in that function group cannot be modified.
Publication 900-UM007D-EN-E - January 2011
Configuration & Basic Operation3-5
Note: The key pressing time can be altered to your requirements. Refer to the
Move to Protect function group Time parameter in the Advanced
Setting function group.
• Operation Function Group — This function group is displayed when
you turn the power ON. You can move to the Protect, Initial Setting,
and Adjustment function groups from this point. This function group is
typically selected during operation. During operation, the process value
(PV), and manipulated variable (MV) can be monitored, and the SP,
Alarm Value, and Upper- and Lower-Limit Alarm parameters can be
monitored and modified.
• Adjustment Function Group — To move to this function group,
press the
group. This function group is used to enter configuration values and
offset values for control. This function group contains parameters for
AT (Auto-Tuning), communications writing enable/disable, hysteresis,
multi-SP, Heater Burnout Alarm (HBA), Heater Short Alarm (HSA),
and PID constants. You can move to the top parameter of the Initial
Setting, Protect, and Operation function groups from here.

• Monitor/Setting Item Function Group (900-TC8)— To switch to
the Monitor/Setting Item function group press the PF key from the
Operation or Adjustment group. The parameter(s) configured for
Monitor/Setting Item 1 to 5 can be displayed. You can move from the
Monitor/Setting Item to the Operation of Initial Setting function
groups. Only the 900-TC8 supports this function group.
• Manual Control Function Group — When the
at least 3 seconds from the Operation function group’s auto/manual
switching display, the Manual Control function group will be displayed.
(The MANU indicator will light.) When the PF setting is configured to
A-M (auto/manual) and PF key is pressed for more than 1 second in the
Operation or Adjustment function group the Manual Control group will
be displayed (900-TC8 only).This is the function group for changing the
MV in manual mode. To return to the Operation function group, press
O key for at least 1 second.
the
• Initial Setting Function Group — To move to the Initial Setting
function group from the Operation or the Adjustment function group,

Note: Pressing the O key for at least 3 seconds in the Operation
function group’s auto/manual switching display will move to the Manual
Control function group, and not the Initial Setting function group.
• Advanced Setting Function Group — To move to the Advanced
Setting function group, set the Initial Setting/Communications Protect
parameter in the protect function group to 0 and then, in the Initial
Setting function group, input the password (−169). From the Advanced
Setting function group, it is possible to move to the Calibration function
group or to the Initial Setting function group. This function group is for
setting the display auto-return time, event input assignments, standby
sequence, and alarm hysteresis, and it is the function group for moving
to the user calibration.
• Communications Setting Function Group — To move to the
Communications Setting function group from the Initial Setting group,
press the
O key once (for less than 1 second). When using the
communications function, set the communications conditions in this
group. Communicating with a personal computer (host computer)
allows set points to be read and written, and Manipulated Variables
(MV) to be monitored.
• Calibration Function Group — To move to the Calibration function
group, input the password (1201) from the Advanced Setting group. The
Calibration function group is for offsetting error in the input circuit.
You cannot move to other function groups from the Calibration group
by operating the keys on the front panel. To cancel this function group,
turn the power OFF then back ON again.

and 900-TC16 controller support a fourth input/sensor type, analog inputs.
Program/configure the Input Type matched to your sensor using the Input
Type parameter (See Table 3.C). The Bulletin 900-TC8, 900-TC16, and
900-TC32 general controller specifications support two general types of
Global Temperature (GT) inputs: (1) platinum resistance thermometer input
and (2) thermocouple Input Types (refer to Table 3.C). The Bulletin 900-TC8
and 900-TC16 controller support a third a third GT input, analog inputs (refer
to Table 3.D). Check the cat. no. of your Bulletin 900 components at purchase
to ensure it matches your input requirements (refer to Tables 1.B and 1.D).

Selecting PID Control or
ON/OFF Control
Overview
The Bulletin 900 Controller supports two control methods: (1) 2-PID control
and (2) ON/OFF control. The control method is selected by the PID
ON/OFF parameter in the Initial Setting function group. When this
parameter is configured to pid, 2-PID control is set, and when configured to
onof, ON/OFF control is set.
Note: The default is ON/OFF control.
2-PID Control
Controller configured/selected P, I, and D (Proportional, Integral, and
Derivative) control parameters are set by the AT (Auto-Tuning) and ST
(Self-Tuning) parameters, or by manual (user) setup. For manual (user) PID
control, set the PID constants in the Proportional Band (P), Integral Time (I),
and Derivative Time (D) parameters. For more details refer to page 3-30.
Publication 900-UM007D-EN-E - January 2011
ON/OFF Control
In the ON/OFF control method, the control output (MV) is turned ON when
the process value (measured temperature, flow, etc.) is lower than the current
set point, and the control output is turned OFF when the process value is
higher than the current set point. This is known as reverse operation. Direct
operation refers to control where the manipulated variable is increased
according to the increase in the process value. Refer to page 3-25 for more
details.
Configuration & Basic Operation3-17

Configuring the Output
Parameters
Control Period
The Control Period parameter is used in the PID control method and allows
you to adjust the minimum amount of time between ON cycles of the
ON/OFF output (MV). This is sometimes referred to as timed proportional
PID control.
Figure 3.19 — Control Period Parameter
Control
period
(OUT1)
Control
period
(OUT2)
A shorter period may provide better ON/OFF control performance. We
recommend setting the control period to 20 seconds or more. In the case of
electromechanical relay outputs, doing this will improve its life expectancy. If
you are using an ON/OFF voltage output (SSR) setting, a shorter time will not
drastically impact the life of the SSR, since it is rated by the number of ON
hours. If necessary, readjust the Control Period by trial operation to meet the
needs of your application.
• You can configure the individual control period values in the Control
Period (HEAT) and Control Period (COOL) parameters (Initial Setting
function group). Note: The default is 20 seconds.
• The Control Period (COOL) parameter can be used only in the heating
and cooling control method.
• When Control Output 1 is used as an analog current output, the Control
Period (HEAT) parameter cannot be used.
Note: The Control Period parameter allows what is typically called Time
Proportioning ON/OFF Control to be done in the 2-PID method.
Direct/Reverse Operation
Figure 3.20 — Direct/Reverse Operation
Direct operation refers to control where the manipulated variable (MV) is
increased according to the increase in the process value (PV). Alternatively,
reverse operation refers to control where the manipulated variable (MV) is
decreased according to the increase in the process value (refer to Figure 3.21).
Direct/reverse operation can be used in ON/OFF or PID control.

For example, when the process value (PV) temperature is lower than the set
point (SP) temperature in a heating control system, the manipulated variable
(OUT1) increases (ON) by the difference between the PV and SP values.
Accordingly, this becomes reverse operation in a heating control system, or
alternatively, direct operation in a cooling control system.
Direct/reverse operation is set in the Direct/Reverse Operation parameter
(Initial Setting function group).
Note: The Direct/Reverse Operation parameter default is reverse operation.

Executing the ON/OFF
Control Method
Overview
In the reverse operation ON/OFF control method, the control output (MV)
turns OFF when the controlled temperature (PV) reaches the user-defined set
point. When the control output (MV) turns OFF, the controlled temperature
begins to fall and the control output turns ON again. This operation is
repeated at a certain point. At this time, how much the temperature must fall
before the control output turns ON again is determined by the Hysteresis
(HEAT) parameter. Also, how much the manipulated variable must be
adjusted in response to the increase or decrease in the process value is
determined by the Direct/Reverse Operation parameter.
ON/OFF Control Parameters
Switching between the 2-PID control method and ON/OFF control method
is carried out by the PID ON/OFF parameter (Initial Setting function group).
When this parameter is configured to pid, 2-PID control is selected, and
when configured to onof, ON/OFF control is selected.

Hysteresis
In the ON/OFF control method, hysteresis is used to provide a
margin/differential for switching the control output ON when the controlled
temperature moves away from the required set point. The Hysteresis
parameter is used to give stability to the output around the set point.
The hysteresis value for HEAT control output and COOL control output
functions are configured in the Hysteresis (HEAT) and Hysteresis (COOL)
parameter functions respectively. In standard heating or cooling control, the
HEAT Hysteresis setting is used as the hysteresis setting (Adjustment function
group) regardless of the control mode, heating control or cooling control.

Overview
When you configure the controller to execute Auto-Tuning, the optimum PID
constants for the current set point during program execution are
automatically configured by the controller forcibly changing the manipulated
variable (MV) to calculate the characteristics (called the limit cycle method) of
the control target.
Either 40% AT or 100% AT can be selected depending on the width of MV
variation in the limit cycle. In the AT Execute/Cancel parameter, specify
at-2 (100% AT) or at-1 (40% AT). To cancel AT, specify off (AT cancel).
• Only 100% AT can be executed for heating and cooling control.
• AT cannot be executed when control has stopped or during ON/OFF
control.
• The results of AT are reflected in the Proportional Band (P), Integral Time
(I), and Derivative Time (D) parameters in the Adjustment function group.
The result of a controller AT cycle can be viewed/monitored from the
Proportional Band (P), Integral Time (I), and Derivative Time (D) parameters
in the Adjustment function group.
Figure 3.56 — PID
AT Description and Display Consideration
AT (Auto-Tuning) is started when you configure either at-2 (100%) or
at-1 (40% AT).During execution of AT, the No. 1 display for the AT
Execute/Cancel parameter blinks (refer to Figure 3.57). When AT ends, the
AT Execute/Cancel parameter turns OFF, and the No. 1 display stops
blinking.
