Note The E5jJ will be in ON/OFF control mode regardless of the setting of pin 3 if pin
The alarm output is ON the moment the E5jJ is turned on because the process
value is within the alarm range. To prevent this, select a mode with a standby
sequence. If a mode with a await sequence is selected, the alarm output will not
be ON even if the process value is within the alarm range unless the process
value once goes out of the alarm range. The following diagram shows the opera-
tion of the E5jJ in lower limit alarm mode with a standby sequence.
It is possible to change the alarm hysteresis (set to 0.2 C before shipping) on the
engineering level.
All the function selector pins are factory-set to OFF.
Refer to the following table for function switch setting.
2 is set to ON.
If pin 1 of the E5jJ is set to OFF, when the process temperature is lower than the
set point, the E5jJ will operate so that the heater output will increase.
If pin 1 of the E5jJ is set to ON, when the process temperature is higher than the
set point, the E5jJ will operate so that the output of cooling water will increase.
The ON/OFF control is also called two-position operation.
Set the E5jJ in this mode for P, PI, or PD control or if the most suitable PID
constants for the controlled device are already known.
Set the E5jJ in this mode so that Fuzzy self-tuning adjusts the PID constants to
the most suitable values according to the controlled device for ideal temperature
control. Refer to Section 4 Fuzzy Self-tuning for details.
Set pin 4 to ON if it is necessary to change any parameter on the engineering
level. Set this pin to OFF for normal operation.
