• The display characters may not be visible in external sunlight or heavily illuminated indoor
• Please avoid places with heat accumulation caused by direct sunlight, radiant heat, etc.
• When water enters, short circuit or fire may occur, so please inspect the product carefully.
• For thermocouple input, use the predetermined compensating cable (temperature errors occur when using ordinary cable).
• For RTD input, use a cable with small lead wire resistance and without resistance difference among 3 wires (temperature errors occur if the resistance value among 3 wires is different).
• Use the input signal line away from power line and load line to avoid the influence of inductive
• Input signal line and output signal line should be separated from each If separation is not possible, use shield wires for input signal line.
• Use a non-grounded sensor for thermocouple (using a grounded sensor may cause malfunctions to the device due to short circuits).
• When there is a lot of noise from the power, we recommend to use insulation transformer and noise Please install the noise filter to a grounded panel or structure, etc. and make the wiring of noise filter output and product power supply terminal as short as possible.

Main function description

Auto-tuning (AT)
The auto-tuning function automatically measures, computes the control system characteristics, and automatically sets the optimum proportional
band (P), integral time (1),and derivative time(D) constants. Press and hold and   simultaneously for more than 2 sec. to start the auto tuning. When auto- tuning is terminated, the control starts automatically.
Alarm

• Alarm usage
  AX series supports 2 independent alarms (AL1 and AL2). These alarms can assign AL1 or AL2 signal to RLY1~RLY3 outputs and be used.
  If alarm signal is not assigned to RLY1-RLY3 then the menu related to the alarm will not be displayed.

• Alarm hold operation
  If the low alarm is turned ON while the power is supplied and the temperature increases, set (alarm n standby mode) to ON, in order to prevent the low alarm from turning ON while the temperature increases, and you will be able to prevent the low alarm operation from power on until the alarm set value is exited.

• Alarm output LOCK
  If the value is set to ON, alarm output is not cancelled even during alarm cancel condition, after the alarm is output.
  Press and hold for approx. 2 sec. to cancel alarm output.

Loop break alarm (LBA)
When the control output value by PID operation is “0”% or “100%” in the control system, it detects heater breaks and sensor break actuator
breakdowns by comparing the change amount of measured value at each set time. You can also set the LBA deadband so that it is not affected by
normal control loops.

1. When control output value by PID operation is 100%, if the temperature does not increase more than L bAw value within the LBA set time, LBA output will turn ON.
2. When control output value by PID operation is 0%, if the temperature does not decrease more than L b Ru value within the LBA set time, LBA output will turn ON.

Time share cycle control and phase control of voltage pulse output ※ for SSR output only
When selecting control output type as SSR, you can select the voltage pulse output type. The time share cycle control turns ON/OFF the output by proportioning time to the output amount at regular time cycles. Set in the period parameter of control output. Within half cycle of power wave, the phase control controls the output amount by computing the output ON phase, depending on output amount.
More continuous output than cycle control can be obtained. However, when using the phase control, users must use RANDOM ON/OFF type SSR.

Operation mode
Supplying the power after wiring will display the current temperature. Every time you press the set temperature and output amount will be displayed alternatively on the set value (SV) displaying unit.
User setup mode
User setup mode is the mode that sets the set values changed by users frequently such as alarm and loop break alarm (LBA) set values.
The parameters of the operator setup mode are also displayed in the user setup mode, so that they can be easily set.
Operator setup mode
Operator setup mode is the setting mode that sets the specifications of the temperature controller when the engineer installs it for the first time.
Pressing and simultaneously for more than 2 sec. in the operation mode or user setup mode will enter to the operator setup mode.
Pressing and again for more than 2 sec. will return to the operation mode.



SV change

1. In operator setup mode, when SuE parameter value is on, you can change value on operation mode with left, Down, Right and set with
2. In operator setup mode, when SuE parameter value is off , you can change value on user setup mode parameter with left, Down, Right and set with .

Input error display
When input break (sensor break) occurs or when the maximum temperature range is exceeded, will be displayed
