3. Wiring
3.1 TTM-P4W series
3.2 Caution on wiring
Before wiring, be sure to turn off the power supply. Otherwise, you may get an
electric shock.
This equipment does not execute control operation for about 4 seconds after the
power is turned on. (Control output does not work. during the period)
Pay attention when you use this equipment for interlock circuit.
Confirm the wirings of the input terminal, power terminal, and optional terminal
by reading the label at the side of the equipment.
- Use crimping terminals matching to M3.5 screws. Also, when you wire to the central terminals,
tighten the wire directly.
- As for wire rods to be used for connecting this equipment with a thermocouple, use a specific
compensating lead wire or wire itself.
- When you use this equipment near the source of noise, use a shielded wire. Also, do not wire the
input/output line in the same duct or wire conduit.
- Leave the input/output signal line more than 50 cm away from the power and load lines.

4.3 Wait operation
If the measured value (PV) has not reached the Wait Zone after the step time has elapsed,
the next step will not start.
However, after the wait time has elapsed, the next step begins.
At the wait operation, the indication at SV blinks.

-When the external input is open, the reset mode is set, and when the external input is closed, the operation mode is set.
4.8 Timer operation function
-It is a function to count the time without controlling in step 1. After "Step 1 Time" has elapsed, shift to the next step and
start control.
-The function is enabled when all of the following conditions ①to ③are met.
①Set "SV / PV start selection setting" to "PV start 1" or "PV start 2"
②Set "Step 1 temperature setting" to " (lower limit -1)"
③Set "Step 1 hour setting" to "1 minute" or more

5. Before Program Operation
You can select the input type. Thermocouple(K, J, R, T, N, S, B) and RTD(Pt100) are provided for
this product.
In this Instruction Manual, the following symbol is used in order to use this equipment safely.
Before using this equipment, be sure to set the input type.
- This equipment can handle PID control. Because the control parameter can be set independently for
low, middle, and high temperature, be sure to set each control temperature range.
The setting by key input is stored even though the power is turned off.

6.2 Detailed description of modes
①Reset mode
- This mode will stop control. (The system becomes this mode when the power is turned on.)
②Operation mode
- This mode will conduct programmed run control. (The RUN lamp lights.)
- The SV display will blink while a wait operation is in process in the wait zone or wait time.
- After a patterned operation is complete, the SV display will display " " and stop the
control. The PV display will display the current temperature.
- Holding the ▽key down for 3 seconds during operation will enable step feed.
③Pause mode
- This mode will pause programmed run control. (The RUN lamp blinks.) It will stop the time
and maintain the control temperature measured at that point in time.
④Pattern number setting mode
- This mode will set the pattern number of the program to be executed.
- Use the △and ▽keys to set a pattern number.
- When the system shifted from "operation mode," holding the ▽key down for 3 seconds will
enable step feed.
- When the system shifted from "operation mode," pressing the PATT./STEP key will display
the time elapsed and time setting.
PV screen: time elapsed, SV screen: time setting
- Pressing the △and ▽simultaneously while holding down the PATT./STEP will turn on all
the indicators.
<Display when shifted from reset mode>
PV: Displays the pattern number selection
character.
SV: Displays the pattern number setting.
<Display when shifted from operation mode>
PV:Displays the pattern number being
executed or the time elapsed.
SV:Displays the step number being executed
or the time setting.

⑤Programming mode
- This mode will set the program for each pattern.
- Setting the time to 0 minutes will invalidate that particular step.

- If you press the [▽] key when the temperature setting for each step is the minimum value in the
setting range, " " will be displayed, and on or after the set step, it will be invalid and the setting
parameters will not be displayed. The operation ends at the step before the step set as " ".
- In changing a setting during operation, you cannot change the step temperature or step time during
operation.
- If you press the [▽] key when the temperature setting in step 1 of each pattern is the minimum
value in the setting range, " " will be displayed, and timer operation will be performed in step
1 of the set pattern. For details, refer to "4.8. Timer operation function".
- If all steps are set to their initial values (0°C), setting a temperature will automatically set the next
step to the same temperature as well.
- Setting a step time to a value higher than the maximum in the setting range (displayed as " ")
will cause the product to run continuously at the set temperature in that particular step.
