4D-3637-A 1-2
1.1 Feature
★Improved controllability due to new PID algorithm
(1) Time required to stabilize after start of control has been reduced (compared to Toho’s other models).
(2) Jumpless control function is supported, where post-disturbance overshoots are suppressed.
(3) Selection can be made from three types of PIDs.
(PID auto-tuning with the overshoot suppression function is set as factory default.)
★Full multi-input
Thermocouples (13 types), resistance temperature detector (2 types), voltage (5 types) and current (one
type) are achieved as input specifications on a single unit. Their changes are possible through setting
changes of parameters. (“K thermocouple” is set as factory default)
★Compact-sized with dimension of 59.7 mm (TTM-214) or 65 mm (other than TTM-214) in depth
★Sampling cycle of 200 ms
★Loader communication function
Best suited for setting various parameters
Dedicated cable: Option (with charge) (See page 7-9 for specifications.)
Dedicated software: Option (free-of-charge)
★Blind function and priority screen for a simplified operation
Blind function:Among multiple parameters, only those needed can be displayed.
Priority screen: By transferring the necessary parameter screen to the operating mode screen, indication as
well as the setting would be possible without calling the parameter screens. (max. 20 screens)
★The valve position proportional control is made possible without feedback resistance.
★Bank function
Each process value (such as SV, PID constants) which varies in each process can be set at every bank,
enabling the setting changes according to the content of the process. (max. 8 points)
★Simple timer function
Control of “start or stop of control after predetermined time has elapsed” can be done on a single unit.
The independent use of timer is also allowed. (Independent 3 points)
★Protective structure In compliance with IP66 or equivalent (TTM-214 only)
★Applicable to various instrumentation systems, using manual control
★Password function
★Modification to the settings at factory default is possible.
★Ramp function enables the setting of gradient.
★Soft-start function
During PID control, a limit can be applied to an operation volume for a predetermined period of time
when the power switched.
★Delay timer function
During ON/OFF control, the control output (primary/secondary) can be done with a predetermined lag
time.
★Program run function
A max. of 8-step program operation is possible.
★Bank auto-switchover run function
A bank auto-switchover run is possible by using 8 banks at most.

4D-3637-A 1-3

■Communication function
★Communication
* This function is for communication with a host computer. (The communication function option is
required.)
* Communication protocol TOHO protocol
MODBUS protocol (RTU mode)
MODBUS protocol (ASCII mode)
* Interface RS-485
* For detailed specifications, see pages 6-65 and 66.
★Loader communication
* This communication function is for setting all data of TTM-210 series in a lump.
* In order to use the loader communication, the dedicated software for the communication must be
installed on the personal computer (PC) being used.
* To connect TTM-210 series to your PC, TOHO’s dedicated connection cable “TTM-LOADER” (sold
separately) is required.
(For the product specifications, see page 7-9.)
* When normal communication (or communication in option) is used (or active), the loader
communication cannot be used.

1.6 Basic flow of setting
Power-on
The mode changes to either “constant value run mode”or “program run mode”when four seconds are
elapsed after the power is turned-on.
Initial screen
4 sec
* Constant run value mode is established with the SET 21 operating type setting (C/P =0).
In addition, the SET 21 and 22 parameters are not displayed.
* With SET 23 bAF =1, the auto bank switchover function is selectable.
With bAF =0, the SET 23 parameters are not displayed.
Constant value run mode
* All setting item selection screens can move to the
constant value run mode screen.
MODE key for 2 seconds
The screen SET 01 appears when the run mode
screen moves to each setting item selection screen.
Each setting item selection screen
SET 01 - SET 23
* Using the ▲/▼key, the setting item selection
screens SET 01 to SET 23 are displayed in
sequence.
(In case of no function registered, the
corresponding screen is not displayed.)
(For bank auto-switchover, see page 6-80.)
Blind setting

SET
* Each parameter setting
screen is displayed in
sequence when the MODE
key is pressed on the
parameter setting screen,
which is displayed when the
MODE key is pressed in each
setting item selection screen
(SET**). Holding the MODE
key pressed for at least 2
seconds moves each
parameter setting screen back
to the run mode screen.
Program run mode
* Program run mode is established
with the SET 21 operating type
setting (C/P =0).
* With SET 23 bAF =1,
the auto bank
switchover function
is selectable.
With bAF =0, the
SET 23 parameters
are not displayed.
MODE key for 2 seconds
Each setting item selection

* Using the ▲/▼key, the setting item selection
screens SET 01 to SET 23 open in sequence.
(In case of no function registered, the
corresponding screen is not displayed.)
(For program run, see page 6-73.)
(For bank auto-switchover, see page 6-80.)

* Each parameter setting screen
is displayed in sequence when
the MODE key is pressed on the
parameter setting screen, which
is displayed when the MODE
key is pressed in each setting
item selection screen (SET**).
Holding the MODE key pressed
for at least 2 seconds moves
each parameter setting screen
back to the run mode screen.
* A shortcut to SET 22 can be
made if FU* =d is set for the
SET 3 function key function
setting.
(For details, see pages 6-12 and
13.)
* The screen moves back to the run mode screen in case of no key operation in each setting item
selection screen or parameter setting screen in each SET for about 2 minutes.
* For how to set the blind setting, see pages 4-27 and 28, the section 4-2-9 “Basic operation.”

2.1 Precautions on installation
Warning
Ensure to turn the power supply off before beginning removal or reinstallation of the equipment in order to prevent
an electric shock or equipment failure.
★Ambient temperature and humidity (the equipment to be used in the specified range as listed below)
(1) Temperature range: 0 to 50 °C
(2) Humidity range: 20 to 85% RH (no dew condensation allowed)
(3) Installation gradient: Base plane ± 10 degrees
★Do not install the equipment in the following places.
(1) Where temperature abruptly changes to generate dew
(2) Where corrosive or flammable gases are generated
(3) Where water, oil, steam or chemicals are received
(4) Where vibration or noise is directly applied
(5) Where dusty or salty ambience, or many iron scraps is present
(6) Where direct sunlight is received
(7) Where circuits may negatively be affected by static electricity, noise or magnetism
(8) Where direct warm or cool air is received from an air-conditioner
★Precautions on installation
(1) Provide sufficient space for ventilation so that the ambient temperature does not rise to 50 °C or
higher. In case that the temperature of 50 °C or higher is suspected, use a fan or air-conditioner to
cool the ambience.
Take care that no cold air flows directly on the equipment.
(2) Do not install the equipment on a device that may generate large heat, such as heater and
transformer.
(3) Install the equipment away as much distant as possible from high-voltage devices, power lines or
power equipment.
(4) Do not block off the ventilation opening on the equipment. Ensure a sufficient gap between
stacked units of equipment.

2.2 How to install or remove the equipment
★Installation on a panel
(1) Make an opening on the panel.
(2) Insert the equipment into the opening.
(3) Install the mounting attachment from behind the panel. Ensure that the equipment is securely
fixed.
* Conduct wiring after the equipment is installed.
* Turn on the power after the wiring.
TTM-214 TTM-215/217/219
★Removal from the panel
(1) Turn off the power.
(2) Disconnect the wiring.
(3) Insert a flat-head screw driver into the clearance formed between gabs on the equipment and
attachment. Turn the screw driver clockwise or counterclockwise to dislocate the gabs to remove
the attachment from the equipment.
(4) Remove the equipment from the panel.
* Ensure to conduct removal work after turning off the power.
