3. Operation

The sensor input character and temperature unit are indicated on the PV display for approx. 3

seconds after the power is turned on, and the rated scale maximum value is indicated on the SV display. (Table 3.1-1) (If the other value is set in the scaling high limit value, it is indicated on the SV display.) During this time all outputs and the LED indicators are on their OFF status. After a while control starts indicating actual temperature on the PV display and setting value on the SV display.

Sensor correction function

This corrects the input value from the sensor. When a sensor cannot be set at a location where control is desired, the sensor measuring temperature may deviate from the temperature in the When controlling with multiple controllers, the accuracy of the sensors has influence on the control. Therefore In such case the control can be set at the desired temperature by shifting the input value of the sensors.

Loop break alarm

The alarm will be activated when the process variable (PV) does not rise as much value as the span or

greater within the time it takes to assess the Loop break alarm after the manipulated variable has re 0% or the output low limit value. When the control action is Direct (Cooling), the alarm acts conversely.

3.6 Control output manipulated variable indication

Name and Description

Control output manipulated variable indication

Press the key for approx. 3 seconds during PV/SV indication mode. Keep pressing the key until the output manipulated variable shows up, though the main

setting mode appears during the process.

(The control output manipulated variable is indicated on the SV display and the decimal point at

the second digit blinks in 0.5 seconds cycle.)

Pressing the key again, it reverts to the PV/SV mode.

4. Converter function

The converter function of this instrument converts each input (Thermocouple, RTD, DC voltage and

DC current input) value to 4 to 20mA and outputs taking advantage of the control parameter of the controller.

When this instrument is used as a converter, follow the process (1) to (7) described below.

When the process (1) to (7) is finished, this can be used as a converter.

(1): Wire and connect this instrument. (Power, Input and Output)

(2): Turn the power of this instrument ON.

(3): Call the “Secure Menu" by pressing the and key (for approx 3s).

(4): Select the sensor type from “Sensor selection ( )”.

(5): Set the high limit of the value which is going to be converted from “Scaling high limit setting ( )". (6): Set the low limit of the value which is going to be converted from “Scaling low limit setting ( )”.

(7): Select converter (

• Outputs the input from scaling low limit setting value to high limit value in 4 to 20mA. The ratio of the changing quantity resolution is 1 to 1000 to scaling span.

• When functioning alarm action by Converter function, set the alarm action to Process alarm action.

If converter function is selected from “Controller/Converter function selection” in the Secure Menu, the parameter below is automatically set. (Table 4.1-1).

and decreasing manual reset value. Output decreases when proportional band value is set to + side, on the other hand output increases when it is set to – side.

When shifting from converter function to controller function, the control parameter and values set by converter function are held as they are even if the function is switched to controller function. So, correct the control parameter and values set by converter function to the value necessary to the controller function after switching to the controller function.

5. Running

When mounting and wiring to the control panel (DIN rail) are finished, running starts following the next

procedure.

(1) Turn the power supply to the SCZ10-ON.

For approx. 3s after power on, the character of the sensor type and temperature unit are indicated

on the PV display, and the rated maximum value is indicated on the SV display. See [Table 3.1-1]. (If any other value is set at the main setting value high limit setting, SV display indicates it.) During this time, all outputs and LED indicators are in their OFF status. After that PV display indicates actual temperature and SV display indicates the main setting value.

(2) Input the setting value.

Input each setting value referring to “3. Operation”.

(3) Turn the load circuit power ON.

Starts control action so as to keep temperature of the controlled object at the main setting value.

6. Other functions

(1) Power failure countermeasure.

Backs up the setting data in non-volatile IC memory.

(2) Self diagnosis

The CPU is monitored by a watchdog timer and when any abnormal status is found on the CPU,

the controller is switched to warm-up status.

(3) Automatic cold junction temperature compensation (Only thermocouple input)

Detects the temperature at the connection terminal between thermocouple and instrument and

keeps it on the same status at which the reference junction is located at 0°C (32° F).

(4) Sensor burnout (Burnout)

When thermocouple or RTD input is burnt out, control output is turned OFF (DC current output

type: control output low limit) and “ ” blinks on the PV display.

When DC voltage and DC current input are burnt out, the status is as follows.

When DC current input (4 to 20mA) and DC voltage input (1 to 5V) are burnt out “ ” blinks

on the PV display.

When DC voltage input (0 to 1V) is burnt out, “ ” blinks on the PV display.

When DC current input (0 to 20mA) is burnt out, the same value at 0mA is indicated.

When DC current input (0 to 10V) is burnt out, a value close to 0V is indicated.

(5) Input burnout indication

Thermocouple, RTD input

and control output is turned OFF (DC current output type: control output low limit setting value). However, in the case of the range with a decimal point when PV exceeds -199.9°C(°F), “ ” blinks and control is carried out until the value becomes [-199.9 - (50°C or 100°F)] or less.

RTD input

If the PV value exceeds [Input range low limit – (input span x 1)] “ ” blinks on the PV display

and control output is turned OFF (DC current output type: control output low limit setting value). However, in the case of the range with a decimal point when PV exceeds -199.9°C (°F) “ ” blinks and control is carried out until the value becomes [-199.9 - (input span x 1%)] or less.

DC voltage and current input

10. Wiring

Warning

Turn the power supplied to the instrument OFF before wiring or checking.

Working or touching the terminal with the power switched ON may result in an Electric Shock which could cause severe injury or death.

Caution

• Do not drop wire chips into SCZ10 when wiring, because they could cause fire, malfunction and trouble

• Insert the connecting cable into the designated connector securely to prevent malfunction, or it

may cause malfunction due to imperfect contact.

• Connect the AC power wiring to the designated terminal as is written in this Instruction manual, or it may burn and damage

• Tighten the terminal screw with the specified torque,

• Use thermocouple and compensating lead wire that fit sensor input specification of this unit.

• Use 3-wire RTD that fits sensor input specification of this unit.

• Do not

• Keep input wire (Thermocouple, RTD) away from power source and load wire when wiring.

• To prevent the unit from harmful effects of the unexpected level noise, it is recommended that a
