3. WIRING

3.1 Wiring Cautions

• For thermocouple input, use the appropriate compensation wire.

• For RTD input, use low resistance lead wire with no difference in

resistance between the three lead wires.

• To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric equipment.

• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

Instrument power

Shorten distance between pitches

- Shorten the distance between the twisted power supply wire pitches

to achieve the most effective noise reduction.

- Always install the noise filter on a grounded panel. Minimize the

wiring distance between the noise filter output and the instrument power supply terminals to achieve the most effective noise reduction.

- Do not connect fuses or switches to the noise filter output wiring as

this will reduce the effectiveness of the noise filter.

• Power supply wiring must be twisted and have a low voltage drop.

• About 5 to 6 seconds are required as preparation time for contact

output every time the instrument is turned on. Use a delay relay when the output line, is used for an external interlock circuit.

• This instrument is not furnished with a power supply switch or fuses. Therefore, if a fuse or power supply switch is required, install close to the instrument.

- Fuse type: Time-lag fuse

- Recommended fuse rating: Rated voltage 250 V Rated current: 1 A

• For the current input specification, a resistor of 250 Ω (±0.02 % ±10 ppm, 0.25 W or more) must be connected between the input

termin als. This resistor must be provided by the customer.

• Use the solderless terminal appropriate to the screw size.

- Screw size: M3 x 6

- Recommended tightening torque: 0.4 Nm [4 kgfcm]

• For an instrument with 24 V power supply, supply power from a SELV circuit.

6. OPERATIONS

 All mounting and wiring must be completed before the power is

turned on. If the input signal wiring is disconnected or short-circuited (RTD input only), the instrument determines that burnout has occurred.

− Displays:

• Upscale: Thermocouple input (specify when ordering),

RTD input (when input break)

• Downscale Thermocouple input (specify when ordering), RTD input (when short-circuited), Voltage input (1 to 5 V DC), Current input (4 to 20 mA DC)

• For the voltage (0 to 5 V DC, 0 to 10 V DC*) or current (0 to 20 mA DC) input, the display becomes indefinite (display of about zero value).

* Z-1010 specification

− Outputs:

• Limit output: OFF

• Alarm output: Both of the Alarm 1 and Alarm 2 outputs of this

 A power failure of 20 ms or less will not affect the control action.

When a power failure of more than 20 ms occurs, the instrument assumes that the power has been turned off. When power returns, the controller will retain the conditions that existed prior to shut down.

 The alarm hold action is activated when not only the power is turned

on, but also the SV is changed.

6.1 Operation Procedures

1. Prior to starting operation, check that the mounting and wiring have been finished, and that the limit set value (SV) and various parameters have been set.

2. This instrument does not have a power supply switch.

3. If the power is turned ON, the limit signal continues to be output

until the <RST key is pressed regardless of a measured value. First, press the <RST key briefly for one or more seconds depending on the setting in SL9, then start operation.

6.2 Set Data Lock (LCK) Function

The set data lock restricts parameter setting changes by key operation. This function prevents the operator from making errors during operation. There are 8 set data lock levels.

Parameters protected by Set Data Lock function are still displayed for monitoring.

7. INITIAL SETTING

Parameters in the Initialization mode should be set according to the application before setting any parameter related to operation. Once the Parameters in the Initialization mode are set correctly, those parameters are not necessary to be changed for the same application under normal conditions. If they are changed unnecessarily, it may result in malfunction or failure of the instrument. RKC will not bear any responsibility for malfunction or failure as a result of improper changes in the Initialization mode.

7.1 Go to Initialization Mode

1. Turn on the power to this controller. The instrument goes to the PV/SV display after confirming input type symbol and input range.

2. Press the SET key for two seconds to go to the Parameter Setting Mode from the PV/SV display.

3. Press the SET key until “LCK” (Set Data Lock display) will be displayed.

4. The high-lighted digit indicates which digit can be set. Press <RST key to high-light the thousands digit. (The section in each image of the controller shows the digits which are not high-lighted.)

5. Press the UP key to change 0 to 1.

Set value 0: Initialization mode locked 1: Initialization mode unlocked

6. Press the SET key to store the new set value. The display goes to the next parameter, and the Initialization mode is unlocked. (The parameter displayed varies on the instrument specification.)
