H2 - off correct power supply for the input/output
module
H2 Undervoltage in the input/output module Check of the 24V power supply
H3 - off input/output module is configured as Module 1
(I/O 0...15)
H3 green on input/output module is configured as Module 2
(I/O 16…32)
H3 red blinking watchdog, error executing firmware Turn power supply off and on If the error
occurs again, contact Customer Service.

Fig. 15-22: Definitions of General Status Displays and Error-Clearing
Status Displays for the Inputs:
The status displays for the inputs are ready for operation as soon as
supply voltage is applied to the input/output module.
The following table shows the relationship between input voltage, input
value and LED status.
Input Voltage Input Value LED Status
DC –3 V - 5 V "0" OFF
DC 5 V - 11 V not defined not defined
DC 11 V - 30 V "1" ON

Status Displays for the Outputs
If an output is set to "1," the LED assigned to that output is on.
If an output is set to "1" and the LED is not on, check the following:
• Is the power supply to the outputs connected?
• Is there a short-circuit at the output?
• Is the output turned off in the input/output module because of
overtemperature?
