Pmx Startup Behavior - HBM PMX Operating Manual

Starting up

9.6 PMX startup behavior

Important
PMX initialization takes a few seconds. A self-test of all the modules is run
during this time. All the LEDs flash to indicate this status. Once the self-test
has been completed, you can read the status of each component from the
relevant status LED (see Sections 7.1.1 to 7.1.3)
− When the PMX is switched on, the digital and analog outputs are set to 0 V.
− When the system powers up, the analog outputs are set to 0 V.
− After power-up, the configured and valid outputs are set to
−10 ... + 10 V.
− Invalid (unconfigured) outputs jump to 0 V (safe value).
If an output becomes invalid during operation, it will also jump to 0 V.
− The safe value can be set to any other value, but its default setting is 0 V.
