Installing the MOVI-PLC® advanced DHE41B controller
Mounting/Installation Instructions
LED L4
(PLC status)
The LED L4 indicates the status of the firmware of the MOVI-PLC
®
advanced
DHE41B controller.
LED L5 (user) The LED L5 is freely programmable in the IEC program.
LED L6, L7, L8, L9
(DIO n/m)
The LEDs L6, L7, L8, L9 indicate the status of the binary inputs and outputs (X31:3
- X31:10) n or m (e. g. DIO2/3).
LED L10
(24V / I/O OK)
The LED L10 indicates the status of the voltage supply for binary inputs and
outputs.

Status of the LED L10 Diagnostics Troubleshooting
Green Voltage supply for the binary
inputs/outputs is OK.
-
Off Voltage supply for the binary
inputs/outputs is not applied.
1. Switch off the inverter in which the
MOVI-PLC
®
advanced DHE41B con-
troller is installed.
2. Check and correct the cabling of the
binary inputs/outputs according to the
electrical wiring diagram.
3. Check current consumption of the
connected actuators (max. current →
chapter 8).
4. Switch on the inverter in which the
MOVI-PLC
®
advanced DHE41B con-
troller is installed.
Orange Voltage supply for the binary
inputs/outputs is applied. However,
one of the following faults has
occurred:
• Overload on one or several
binary inputs/outputs
• Overtemperature of the output
driver
• Short circuit in at least one of
the binary inputs/outputs
