Setup Procedure
Section 3-1
• Read the Configuration Error A Status and check that there are no er-
rors.
• Read the Device B Status and check that bit 12 (Configuration Regis-
tered) is OFF.
d. Use the operation command to execute registration of Unit configura-
tion.
e. Use the method outlined in step b) above to reset the EJ1G system
then check the following.
• Read Configuration Error A Status and check that there are no errors.
• Read the Device B Status and check that bit 12 (Configuration Regis-
tered) is ON.
• Check that the COM2 indicator is flashing for all Units.
Note Refer to SECTION 7 Errors and Error Processing to determine the
cause of any errors that occur during when performing the proce-
dure outlined above.
7. Set decimal point position B.
Decimal point position B is set for the HFU.
The decimal point position for the PV is set using the Decimal Point Posi-
tion B parameter. Set the same decimal point position as was set for the
TC2 Unit or TC4 Unit.
Decimal point position B must be set because it is used as the decimal
point position for the SP and alarm values.
In this example, the input type is set to 5 (Thermocouple (K):
−
200 to
1,300) so the decimal point position must be set to 0.
Note The input type can be set separately for each channel, but if different input
types are set, input types with the same decimal point position. Temperature
control will not be executed correctly if different decimal point input types are
used.
8. Make the SP and alarm settings.
The SP and alarm settings are made for the HFU.
