5.Before power up, check if A phase or B phase connects to correct voltage level. (there are three voltage level: +24, +12V and +5V) If +24V signal connects to +5V input terminal, it may damage internal circuit.

6.After power up MPU, it will start to detect extension module. If no external +24VDC power is applied to HC at this time or power is applied after EH MPU completing detecting extension module, the connection will fail. Therefore, power wiring and power supply timing should be as following.

When power supply for HC is +24V_INT:

When power supply for HC is +24V_EXT:

Because start time (t2) of external power supply for HC extension module is unknown, user must make sure that t2+t4 ＜ t1+t5, otherwise HC extension module cannot be detected by MPU.

TRIAL RUN & TROUBLESHOOTING

MPU connects to HC extension module

1.Make sure that the power of MPU and extension unit is OFF before wiring.

2.Open extension port of EH MPU and connect to HC extension unit with cable. There is no connection order for EH MPU to connect extension unit, mix connection is allowed.

3.The power supply of HC extension unit must be external +24VDC power supply.

4.Before power up, check if the load circuit of output points YH0 and YH1 is correct, especially the circuit between YH0+, YH0- and YH1+, YH1-. There is a Zener Diode that is connected between YH0+, YH0- and YH1+, YH1- in HC. If the positive/negative pole is wrong, it may cause unexpected result.

7.The maximum special extension modules number for EH MPU connects is 8 special extension modules. After power is ON, EH will save module codes of connected special modules in D1320~D1327 in order. The module code of 01HC is H’0120. It indicates communication is OK when H’0120 is displayed in the corresponding special D register by using HPP02 or other monitor software.

Troubleshooting

Judge the errors by the indicators on the front panel. When errors occurred on DVP PLC, please check:

☼“POWER” LED

The “POWER” LED at the front of HC extension module will be lit (in green) if the power is on. If the indicator is not on when power up, please remove the wiring on terminals +24V. Once the indicator lights after this, it means that the 24V DC power supply of the PLC is overloaded. Please do not use the DC power supply from the +24V terminals, but use a DC24V power supply instead.

☼L.V. LED

The “L.V.” LED at the front of HC extension module will be lit if input voltage is not enough. The extension module won’t active at this time.
