CAUTION
This is a Class A instrument. In a domestic environment, this instrument may cause radio
interference, in which case the user may be required to take adequate measures.
This instrument is protected from electric shock by reinforced insulation. Provide
reinforced insulation between the wire for the input signal and the wires for instrument
power supply, source of power and loads.
Be sure to provide an appropriate surge control circuit respectively for the following:
- If input/output or signal lines within the building are longer than 30 meters.
- If input/output or signal lines leave the building, regardless the length.
This instrument is designed for installation in an enclosed instrumentation panel. All
high-voltage connections such as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating personnel.
All precautions described in this manual should be taken to avoid damage to the
instrument or equipment.
All wiring must be in accordance with local codes and regulations.
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.
To prevent instrument damage or failure, protect the power line and the input/output lines
from high currents with a protection device such as fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid
electric shock, fire or malfunction.
Tighten each terminal screw to the specified torque found in the manual to avoid electric
shock, fire or malfunction.
For proper operation of this instrument, provide adequate ventilation for heat dispensation.
Do not connect wires to unused terminals as this will interfere with proper operation of the
instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or
discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.
To avoid damage to instrument display, do not rub with an abrasive material or push front
panel with a hard object.
Do not connect modular connectors to telephone line.

1. OUTLINE
This manual describes the communication function of the SR Mini HG SYSTEM and the OMRON
programmable controller (hereafter called PLC).
This manual is attached when the model code of H-PCP-J module is H-PCP-J--D∗
-03E.
For details of the H-PCP-J module, see the Power Supply/CPU Module H-PCP-J
Instruction Manual (IMS01J02-E).
The SR Mini HG SYSTEM can be connected to the OMRON SYSMAC series without using any
program.
The SR Mini HG SYSTEM occupies the fixed area in the PLC data memory for each unit address.
The control unit for SR Mini HG SYSTEM consists of the H-PCP-J module and temperature control
function modules.

The 6-pin type modular connector should be used for the connection to the H-PCP-J module.
Recommended model: TM4P-66P (Manufactured by HIROSE ELECTRIC CO., LTD.,)
Because there is not SG, in case of SYSMAC CS1 series, electric wiring is unnecessary.
Customer is requested to prepare a communication cable fit for the control unit to be
connected by the PLC. Connection cable W-BF-01 * (RKC product) can use to connect
PLC.
* Shields of the cable are connected to SG (No. 6 pin) of the H-PCP-J connector.
A wiring example when using our W-BF-01 connection cable is shown in the following.

SETTING ON THE H-PCP-J MODULE SIDE
4.1 PLC Data Memory Address Setting
Set the data memory address of each control unit using the unit address setting switch at the front of
the H-PCP-J module. For this setting, use a small blade screwdriver.

Up to 4 SR Mini HG SYSTEMs can be connected to a PLC communication port. Therefore the data
memory address uses the 4 SR Mini HG SYSTEMs as a group. The SR Mini HG SYSTEMs
connected to the same PLC communication port sets the address in the same group.
Set unit address of each group including 0, 4, 8 and C by all means. 0, 4, 8 and C work
as a master of communication transfer.
Set unit address within address range of PLC (CPU unit) to use.
