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.

4.1 Set the Number of Patterns

- The maximum number of steps are determined depending on the number of patterns.

- The relationship between the number of patterns and the maximum number of steps is as shown in the table below.

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.

: Wait Zone... This means the deviation area between SV(Setting Value) and

PV(Process Value) enable to start next step.

WAIT TIME

: Wait time... This means the maximum waiting period to start next step when

PV(Process Value) does not reach to the SV(Setting Value).

4.4 PV/SV start

PV start1．．． Operation will start from the Ramp step including the PV at the starting time of Program operation.

In case more than one step applied, it starts the one with smaller step number.

At these area, operation will not start.

Start operation from this point.

step 1 step2 step3 step4

PV start2．．．The operation is started with the PV (Process Value) at the start of operation as the start temperature.

Start operation from this point.

4.7 External Operation Function

-It is a function to switch between reset mode and operation mode by external input (DI).

-When "External operation selection setting" is "ON", the function is enabled.

-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.
