Key Operations
WARNING
To prevent electric shock, the controller should be mounted on the panel so that you do
not accidentally touch the terminals when power is being applied.
IMPORTANT
The temperature controller is shipped with the parameters set at the factory-set
defaults. Check the default values against the “Parameter Lists” in the following page,
and change the parameter settings that need to be changed.
This section explains how to set and register parameter values.
The procedure for changing SP (target setpoint) and A1 (alarm 1 setpoint) can be found on
“Changing Target Setpoint (SP)” and “Changing Alarm 1 Setpoint (A1),” respectively. You can set the
other parameters in the same way.
There are no setup displays for parameters specific to functions, such as the optional alarm output
functions or heating/cooling control, if they were not selected at ordering.
The setting of some parameters (such as the control mode parameter CTL) determines whether the
other parameters are displayed or not.
The flowchart below will help you understand how this works.
CAUTION
At power-on, the temperature controller displays the operating display, but if the input
range setting remains OFF, then “IN” appears. In this case, press the
key to display
the input range code you want to use, then press the
key to register it. (Refer to the
flowchart below.)
(1) You can move between parameter setting displays using the
key.
(2) To change the set value,
(i) Change the display value with the
or
key (the period flashes).
(ii) Press the
key to register the setting.
(3) At the operating display, pressing the
key for at least 3 seconds retrieves the operating
parameter setting display.
(4) At the operating parameter setting display, pressing the
key for at least 3 seconds transfers
back to the operating display. Registering the key-lock parameter LOC to “–1” retrieves the setup
parameter setting display.
(5) At the setup parameter setting display, pressing the
key for at least 3 seconds transfers back
to the operating display.
CUATION
Set “-1” to enter the setup parameter setting
display. But if “LOC=1 or 2” is already set, the
parameter value can not be changed by setting
“LOC=-1” only. To change the parameter value,
set “LOC=0” at first (for disabling keylock),
then set “LOC=-1” once again.
Note: If no key is pressed for a period
of two minutes or more while in
the operating or setup parameter
setting display, the controller
automatically returns to operating
display.

Note: If you cannot change

value, check the

(LOC) setting.
CAUTION
Changing certain setup parameters may automatically
initialize the operation parameters. Therefore, after you
change the setup parameters, always check the operation
parameter settings to find out if appropriate values have
been set for them. If the operation parameters have been
initialized, set them to their appropriate values.
The following instructions assume that the
controller is already receiving power.
Step 1:
Confirm that the controller
shows the operating display
during normal operation.
(See note 1)
If the controller displays PV,
press the key once to
display SP (SP display lam
is on).
Step 1:
Confirm that the controller
shows the operating display
during normal operation.
(See note 1)
Step 3:
Press the key once to
display the current A1
value.
The SP display lamp
flashes quickly.
Step 2:
Press the or key to
change the displayed SP
value to the required value. In
this example, SP is changed
to 200°C.
The period flashes while the value is being changed.
Step 2:
To enter the operating parameter
setting display, press the
key for at least 3 seconds.
If your controller has the /AL or
/HBA option, the display for the
Alarm 1 setpoint (A1) appears.
(If not, control mode (CTL)
appears.)
Step 3:
Press the key once
to register the setting.
The period goes out.
SP is now changed.
Note 1: The operating display shows either PV or SP.
You can find out which data is displayed by the
SP display lamp status.
a. OFF: PV display of operating display
b. ON: SP display of operating display
c. Slow flashing: Parameter code is displayed.
d. Quick flashing: Parameter value is being
changed.
The period goes out.
Step 4:
Press the or key to
change the displayed A1
value to the required value.
In this example, A1 is
changed to 200°C.
The period flashes while the value is being changed.
Step 5:
Press the key once
to register the setting.
The period goes out.
Step 6:
To return to the display at
step 2, press the key
once again.
A1 is now changed.
Another press of the key
calls up the Alarm 2 setpoint
(A2) display.

When Power Failure Occurred during Operation
● Momentary power failures of less than 20ms (or less than 1ms when “/V24” is specified)
have no effect on the controller operation (i.e., normal operation continues).
● For power failures longer than 20ms (or longer than 1ms when “/V24” is specified), however the
status will be as follows.
(The controller action at power recovery is the same as at power-on.)
• Alarm action: Continues (but alarms with a waiting action enter the waiting state once)
• Setting parameters: Maintained
• Auto-tuning: Canceled
