3-8. Before Starting Operation
To begin with, check the wiring and set the items listed below by the setting methods of the screen groups.
Factory-set items and items already set by equipment manufacturers need not be set here.
1. Checking of wiring:
Check that the wiring to connected terminals is carried out properly. Erroneous wiring will result in burnout.
2. Application of operating power:
Apply operating power. The controller is energized and the data display and other lamps light.
3. Setting of measuring range:
Call the screen 1-51 (measuring range code screen) of the screen group 1 and select and register a code from the
measuring range codes. Call the screen 1-52 (temperature unit setting screen) of the screen group 1 and select
and register a temperature unit. For current, voltage or mV input, lower/higher limit values and the position of
decimal point should be set on the screen 1-53, 1-54 or 1-55 respectively.
4. Setting of control mode (PID):
In the case of ON-OFF (two-position) control, call the screen 1-2 (output 1 proportional band setting screen) of the
screen group 1, select OFF and register it. Call the screen 1-3 (output 1 hysteresis setting screen) of the screen
group 1, set and register it.
Follow the same procedure for output 2 if the option is added.
Omit this setting in the case of AT (Auto Tuning).
5. Setting of control output characteristics:
Call the screen 1-45 (control output characteristic setting screen) of the screen group 1 and select either RA
(Reverse Action) or DA (Direct Action) correspondingly to output characteristic specification (Heating/Cooling).
6. Setting of event type:
If the optional event function is added, call the screen 1-21 and/or 1-24 (event alarm type code setting screen) of
the screen group 1 and select and register a code.
7. Setting of analog output:
If the optional analog output function is added, call the screen 1-32 (analog output type setting screen) of the
screen group 1 and select one from the setting range and register it.
8. Note on initialization following data change:
When the code of measuring range, event type or analog output type is changed, a set value is initialized and
resetting is required.
