9. TROUBLESHOOTING
This section lists some basic causes and solutions to be taken when any problem would arise in this
instrument. If you cannot solve a problem, please contact RKC sales office or the agent, on confirming
the type name and specifications of the product.
If the instrument is necessary to be replaced, observe the following warning.
All wiring must be completed before power is turned on to prevent electric shock,
instrument failure, or incorrect action.
The power must be turned off before repairing work for input break and output failure
including replacement of sensor, contactor or SSR, and all wiring must be completed before
power is turned on again.
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, Register addresses: 02BFH)” (P. 84, 127, 153) before setting the data.
“Module initialization” stores the new module configuration in the H
-PCP-J
module.
If data is set before “Module initialization” is performed, the H
-PCP-J
module will set the
previously stored initial data of the old modules in the new modules, which may cause
malfunction.
As all data on PID constants, alarm set values, etc. is managed by the H-PCP module, it
is necessary to re-enter and re-set all data when the H-PCP module is replaced.
However, re-entry and re-set are not required in the following cases.
When data backup software is operating in the module by the external host
computer.
When it is set on the operation panel so that data on the operation panel side is
transferred to the control unit side when the power is turned on again.
CAUTION
To prevent electric shock or instrument failure, always turn off the system
power before replacing the instrument.
To prevent electric shock or instrument failure, always turn off the power
before mounting or removing the instrument.
To prevent electric shock or instrument failure, do not turn on the power until
all wiring is completed. Make sure that the wiring is correct before applying
power to the instrument.
To prevent electric shock or instrument failure, do not touch the inside of the
instrument.
All wiring must be performed by authorized personnel with electrical
experience in this type of work.
