Operating Instructions Temperature Indicating Controller CF1H

***** Note to users *****

Before operating this controller, make sure you have understood the following.

Warning

Turn the power supply to the instrument OFF before wiring or checking. Working or touching the terminal with the power switched ON may result in Electric Shock, which can cause severe injury or death. Moreover, the instrument must be grounded before the power supply to the instrument is turned on.

Caution

Do not apply a commercial power source to the sensor connecting to the input terminal nor allow the power source to come into contact with the sensor, as the input circuit may be burnt out. Set-up by the DIP switch and the rotary switch inside of the controller is required before the power is turned on. The product is factory adjusted as [Sensor input: K, Control action: Fuzzy self-tuning PID, Heating action, Alarm (A1): No alarm action, no standby function, Unit: °C and Program starting form: manual]. Refer to page 9 “Setup”.

It is recommended that the PID auto-tuning be performed on the trial run.

It is advised to provide the protective device against such environmental conditions which may cause damage to the device or contribute to the deterioration of its parts.

If you are mounting this controller to the control panel or machine, read this manual from Chapter 10 “Mounting to control panel” or 11 “Wiring connection” after checking the model name by 1 “Model names”.

If you are operating this controller already mounted, read this manual from Chapter 2 “Name and functions of the sections” or 4 “Operations”.

3.1 Taking the internal assembly out

Before the power supplied to this instrument is on, take the internal assembly out from the case by pushing the hook (bottom of the instrument) in the direction indicated by the arrow and holding the notches.

[Fig. 3.1-1]

Warning

Do not take the inner assembly out nor touch the terminal with the power supply on. Touching the terminal with the power switched ON may result in Electric Shock, which can cause severe injury or death.

3.2 Switch setting (multi-function)

Using a small slotted screwdriver and tweezers, set the Sensor input, Alarm 1 action, Alarm 2 action, Control action, Heating (reverse)/Cooling (direct) action, Alarm 1 and 2 standby functions, Unit °C/°F and Program starting form Auto/Manual change by rotary switch and DIP switch by the following procedure. If the option A2 is not applied, the rotary switch A2 (SW301) will not be equipped.

For RTD input, the minimum value of the negative side is –199.9. For DC input, the minimum value of the negative side is –1999. (Decimal point place follows the selection.) *1: For DC input, the Input range span is the same as the Input range scaling span. *2: For DC input, Input range maximum (minimum) is the same as the Input range scaling maximum (minimum) value.

The alarm will be activated when the process variable (PV) does not rise as much as the span or greater within the time it takes to assess the loop break alarm after the manipulating value has reached 100 % or the output high limit value. The alarm will also be activated when the process variable (PV) does not fall as much value as the span or greater within the time it takes to assess loop break alarm after the manipulating value has reached 0 % or the output low limit value.

When the control action is Direct (Cooling), the alarm acts conversely.

Unlock status. All setting values are changeable.

None of the setting items can be changed.

Only main setting value is changeable.

All setting items can be changed, however, the

value returns to the former value after the power off because the value is not written on the non volatile memory. This mode is used when changing the value temporarily. Since it has no relation to the memory life, it is suitable when the option [CR2 or CR5] is applied.

Fuzzy self-tuning or Auto-tuning PID action will not function if [
