STAHL HMI model :EXICOM ET-416-FX- troubleshooting guide

[electrician1]

Good morning Support

Any experience with STAHL HMI model :EXICOM ET-416-FX.
After re-initiating power to the control panel HMI didn’t boot up. When powering up , the HMI emits 4 beeps and LCD doesn’t power up. Failed HMI was removed from the panel and bench tested in workshop with identical symptoms.

Since this model of HMI is obsolete and no spares on stock client decided to remove identical HMI from another working system ( less critical).
The HMI was then installed on control panel in question and it didn't work i.e when powering up , the HMI emits 4 beeps and LCD doesn’t power up.
This HMI was then tested in workshop and behave the same way.

Voltage inside control cabinet in question is stable 24V DC.

Can’t find any troubleshooting manual for this HMI. What is 4 beeps indicating ?

I didn't see anything about beeps, per se, but perhaps this will prove useful:
