Installing the DH.21B/41B option
Assembly and Installation Notes
LEDs L6, L7, L8,
L9 (DIO n/m)
LEDs L6, L7, L8, L9 indicate the state of the binary inputs and outputs (X31:3 -
X31:10) n or m (e.g. DIO2/3).
LED L10
(24V/ I/OOK)
LEDL10 indicates the state of the voltage supply for binary inputs and outputs.
4.7.8 DIP switch S1
You can use DIP switch S1 to set a default IP address for the Ethernet 2 connection
(X37). This IP address will be applied with the next boot process.

State of L6, L7, L8,
L9 LEDs
Diagnostics Remedy
Off No voltage present.
-
Green Voltage at terminal n.
Red Voltage at terminal m.
Orange Voltage at terminals n and m.
State of the L10 LED Diagnostics Remedy
Green Voltage supply for the binary inputs
and outputs is OK.
-
Off No voltage supply is present at the
binary inputs and outputs.
1. Switch off the inverter in which the
DH.21B/41B option is installed.
2. Check and correct the cabling of the
binary inputs/outputs according to
the electrical wiring diagram.
3. Check the current consumption of
the connected actuators (max.
current → "Technical Data" chapter).
4. Switch on the inverter in which the
DH.21B/41B option is installed.
Orange Voltage supply is present at the binary
inputs and outputs. However, one of
the following faults has occurred:
• Overload on one or more binary
inputs or outputs
• Overtemperature of the output
driver
• Short circuit in at least one of the
binary inputs or outputs
S1 switch setting Meaning
Up IP parameter:
• IP address: 192.168.10.4
• Subnet mask: 255.255.255.0
• Standard gateway: 1.0.0.0
Down Addresses entered in the configuration file (see chapter "Functional
description of terminals, DIP switches and LEDs")
