6. OPERATIONS OF THE BASIC FUNCTIONS
6-2 IMR02C15-E4
6.1 RUN/STOP Transfer
It is possible to transfer between control start (RUN) and control stop (STOP). RUN/STOP transfer
can be performed by key operation, by key operation using the RUN/STOP setting in Engineering
mode, by digital input (DI) [optional] or communication [optional]. All methods of RUN/STOP
operation are linked. For example, when the mode is changed from RUN to STOP via key
operation, the setting of RUN/STOP setting in Engineering mode will also change to “STOP.”
When the digital input RUN/STOP transfer function is used, it is impossible to transfer
RUN/STOP through key operation if the contact is not closed. (When contact opens:
STOP mode is maintained.)
For details of the RUN/STOP transfer by communication, refer to Communication Quick
Instruction Manual (IMR02C41-E) and Communication Instruction Manual
(IMR02C16-E).
State of this instrument when set to STOP mode
STOP display
• STOP lamp lights (Green)
• Displays the STOP symbol “
STOP” on the SV or PV displays
The display content depends on the setting of STOP display selection.
Setting range:
0: STOP on PV display + STOP lamp (green) lights
1: STOP on SV display + STOP lamp (green) lights [Factory set value]
2: STOP lamp (green) lights
Control output
When the time-proportional control output: Output OFF
When the continuous control output: Output of −5 %
Event output
Transmission output
(AO)
The output content depends on the setting of Output action at STOP mode.
Setting range:
0: Both Event output and Transmission output (AO) are off.
[Factory set value]
1: Event output remains unchanged, and Transmission output (AO)
is off.
2: Event output is off, and Transmission output (AO) remains
unchanged.
3: Both Event output and Transmission output (AO) remain
unchanged.
Autotuning (AT) AT canceled (The PID constants are not updated)
For the settings of STOP display selection, and Output action at STOP mode, refer to
8.5 Engineering Mode (P. 8-96, P. 8-97).
State of this instrument when set to RUN mode
If the instrument is transferred to RUN mode from STOP mode, it performs the same operation
(control RUN, event determination start-up) as the power-on.
