Hi,
PDM15 (v1 I believe) with v1.1.6 SW with a Rife analog temp sensor connected to an input. How do you get Sensor Calibration tables to work? I have it configured but it always outputs 0. I tried fudging it with a 2D table which did work, which makes me think it's a bug in v1.1.6?
Thanks
Simon
Hi all,
I'm using a PDM25 as the central control and logic unit in an EV conversion — it drives the HV contactors and passes on shutdown commands from a separate BMS via CAN.
Mine is the earlier revision (it came with the PDM 15/25 manual, not the newer 15/25/35 one), so I'd like to confirm a few behaviours against the right hardware before I finalise the safety design.
Three questions:
If the processor hangs or locks up while the unit is still powered, what happens to the outputs — do they hold their last commanded state, or switch off? I'm trying to work out whether a locked-up PDM could leave an output (and therefore a contactor) energised.
Is there any internal watchdog or fail-safe that switches the outputs off if the processor stops running normally? Or would I need to add an external heartbeat for that?
Can the PDM's…
Hey everyone, I am having an interesting issue. My ECU keeps randomly restarting. I have included a video of the issue. The HS Status on the output goes to 4 which is not listed in the manual anywhere, and the output does not show tripped. I have already replaced the entire engine harness to the ECU. Does this seem like a PDM issue or the ECU itself? Any input would be greatly appreciated!
I took the car out and it shut off again. Interestingly it looks like it took out the whole can bus network because the keypad cycled and would not reconnect. Everything else in the car remained functional. I turned the key off which is wired to C3 to turn on the PDM and still nothing. The only way I was able to everything back working was to shut the main power off and let it sit for 30 seconds.
Hello everyone, someone has a Emtron keypad (grayhill 8) working with the pdm? I would like the hardwire pdm to control it, not the emtron, I try with ID 900,901,902 that is what I could find on the Emtron information but never show up as connected. Any input would be appreciated.
ended up controlling the keypad with the emtron, and using the dbc files from emtron (one have the keypad on it).
Hi, Can you make sure that the last few values are filled in on the sensor calibration table
