Function module replacement
If you add or delete a function module, or change the arrangement of the modules, or replace a
module with a different model, be sure to perform “Module initialization (identifier CL)”
before setting the data. “Module initialization” stores the new module configuration in the
H-PCP module. If data is set before “Module initialization” is performed, the H-PCP module
will set the previously stored initial data of the old modules in the new modules, which may
cause malfunction.
For details on how to initialize the module, refer to SR Mini/SR Mini HG SYSTEM
Supplementary Information Initialize Settings [Extended Communications]
(IMSRM07-E
).
When replacing the function module with the same model code, initialization of a module is
unnecessary. Before replacing the present module with a new one, set channel operation
mode used in the former to Unused mode. Be careful not to remove the module without
first setting this channel to the Unused mode, otherwise a failure will be output from the
H-PCP module. However, the FAIL lamp of the H-PCP module will not light at this time.
In this instrument, even if a function module is detached, the operation of the other channels
can be continued as before. After mounting the normally operating module, set the channel
used by this module to the Normal mode. This operation causes the previously used
temperature set value, PID constants, etc. to be transmitted from the H-PCP module, and it is
possible to use the module as before.
To remove the function module from the mother block, follow the reverse order of module mounting.
Replacement procedure (When replacing the function module with the same model code)
1. Switch the used channel of the faulty module to Unused mode.
2. Turn off the power to the control unit.
3. Remove the module mainframe from the mother block.
4. Mount the normal module mainframe.
5. Turn on the power to the control unit.
6. Switch the used channel to Normal mode.
This operation causes the previously used temperature set value, PID constants, etc. to be
transmitted from the H-PCP module, and it is possible to use the module as before.
7. Replacement end
For details on mounting/removing the module mainframe, refer to the 4.5 Mounting the
Module Mainframe (P. 93) and 4.7 Removing the Module Mainframe (P. 94).
