3-7. Operation preparations
Before operating the controller, you should first check the wiring and carry out the following by screen group setting method.
There is however no need to change the settings that have been set at the factory or already been made by the manufacturer.
1. Wiring check
Make sure the wiring to the connection terminals is correct. Incorrect wiring could result in burnout.
2. Power ON
Turn on the operating power. The displays, etc., light when power is supplied to the controller.
3. Measuring range setting
Select code from Measuring Range Codes of “4-58 Measuring range codes setting screen” of 4 screen group and enter.
Select temperature unit of “4-59 Input unit setting screen” of 4 screen group and enter.
For current, voltage and mV input, set lower limit value, higher limit value and position of decimal point of display contents
for input signal.
(You should also select by 4-60, 4-61 and 4-62 screens by code.)
4. Control mode (PID) setting
For ON-OFF (2 position) action, select OFF by “2-1. Output 1 PID1 proportional band setting screen” of 2 screen group and enter.
Sets hysteresis by “2-2. Output 1 PID1 hysteresis setting screen.”
If equipped with output 2, set by same method.
If using auto tuning (AT) with other than ON-OFF hysteresis, this setting operation is not required.
5. Control output characteristics setting
Select RA (for heating) or DA (for cooling) according to output specification (heating/cooling) on “4-45 Output 1 output
characteristics setting screen” and “4-48 Output 2 output characteristics setting screen” of 4 screen group and enter.
6. Event type setting
If equipped with event, select types of event on “4-2, 4-7 and 4-12 Event type setting screen” of 4 screen group and enter.
7. Analog output setting
If equipped with analog output, select items to be output as analog signals on “4-23 Analog output type setting screen” of 4
screen group and enter.
8. Precaution concerning initialization by data modification
Modifying measuring range code, type of event or type of analog output initializes related setting values (data). The data
must therefore be set again.
